Specific Hormones Functions of FSH and LH [Gonadotropins

  1. READ MORE BELOW! In this video, we explore the functions of the major gonadotropins, FSH and LH, and how they are released. INSTAGRAM | @thecatalystuniversit..
  2. Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). Both these hormones affect the reproductive organs of both the female and the male. They are named for what they do for the ovaries of a female, although they do affect the testes of the male as well. We'll deal with guys first, then the more complicated women. FSH and LH in me
  3. FSH is also critical for sperm production. It supports the function of Sertoli cells, which in turn support many aspects of sperm cell maturation. Control of Gonadotropin Secretion. The principle regulator of LH and FSH secretion is gonadotropin-releasing hormone (GnRH, also known as LH-releasing hormone)
  4. FSH (Follicle Stimulating Hormone) regulates the growth, development, pubertal maturation and reproductive functions of the body. FSH works together with the Luteinizing hormone (LH) to produce testosterone, which plays a major role in the development of the male reproductive organs such as testes and prostate gland and the external sexual.

  6. Follicle-stimulating hormone (FSH) is a gonadotropin, a glycoprotein polypeptide hormone. FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland, and regulates the development, growth, pubertal maturation, and reproductive processes of the body.FSH and luteinizing hormone (LH) work together in the reproductive system
  7. LH levels decrease as the luteal function is regulated by the hormone hCG which is released by the placenta. The woman may have normal LH and FSH levels, about 20 and 15 days after the delivery, respectively

All hormones are tightly controlled in males and go as follows. GnRH, or gonadotropic releasing hormone, is a hormone released by the hypothalamus. It triggers for the release of FSH and LH from the anterior pituitary gland. FSH, or follicle stimulating hormone, targets the testes, specifically, the Sertoli cells. The Sertoli cells stimulate the production of sperm cells FSH - is folliscle stimilating hormone it helps mature eggs within the ovary ready to be realised for fertilization. LH- is the hormone that helps release the eggs that are matrure. Estrogne- this helps ony one egg get through by inhibiting fsh so only one egg is mature ready to be realised, it also maintains the lining of the uteru LH (Luteinsing Hormone) or Interstitial Cell Stimulating Hormone: In females, together with FSH, it triggers ovulation, stimulates conversion of ovarian follicles into corpus luteum and secretion of progesterone in females.It helps in maintaining pregnancy by controlling estrogen and progesterone

Luteinizing hormone (LH, also known as lutropin and sometimes lutrophin) is a hormone produced by gonadotropic cells in the anterior pituitary gland.In females, an acute rise of LH (LH surge) triggers ovulation and development of the corpus luteum.In males, where LH had also been called interstitial cell-stimulating hormone (ICSH), it stimulates Leydig cell production of testosterone What are the functions of follicle-stimulating hormones (FSH) and luteinizing hormones (LH) and the secretion of estrogen from this follicle is dependent on FSH and LH FSH LH; Female: stimulates ovary to produce steroids ovary will produce estradiol during follicular phase and progesterone during luteal phase. surge at midcycle, with LH, triggers ovulation. stimulates ovary to produce steoroids surge at midcycle triggers ovulatio

FSH function. FSH and LH regulate the functions of the ovaries and the testes. In females, FSH stimulates growth and development of follicles in preparation for ovulation and secretion of estrogens by the mature Graafian follicle. LH triggers ovulation and stimulates the secretion of progesterone by the corpus luteum In concert with the other pituitary gonadotropin follicle stimulating hormone (FSH) it is necessary for proper reproductive function: * In the female, an acute rise of LH - the LH surge - triggers.

  1. The decreased levels of LH in children causes delayed puberty and is an indication of ovarian or testicular failure, hormone deficiency, etc. Also Read: Hormones and Hormonal Disorders. This article concludes the introduction to the Luteinizing hormone (LH), their level of production and functions
  2. Follicle stimulating hormone is one of the hormones essential to pubertal development and the function of women's ovaries and men's testes. In women, this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation
  3. Human gonadotrophin preparations have been used in the treatment of infertility for almost four decades. The earliest preparations were derived from urine from postmenopausal women and contained approximately equal amounts of follicle stimulating hormone (FSH) and luteinizing hormone (LH) activities
  4. Follicle-stimulating hormone (FSH) is a hormone that regulates many processes related to fertility. Levels of FSH that are too low or too high can have a negative impact on your fertility.<br /> Read on to discover more about the functions of follicle-stimulating hormone
  5. The follicle-stimulating hormone (FSH) is part of the two gonadotropins, FSH and LH. Gonadotropins are necessary for normal reproductive function in both males and females. 1. In women FSH stimulates the growth of an ovarian follicle. In the folli..

Hormone - Hormone - Luteinizing hormone (interstitial-cell-stimulating hormone): Luteinizing hormone (LH; also called interstitial-cell-stimulating hormone, or ICSH) is another gonadotropin, a glycoprotein with a molecular weight of 26,000 in humans. In the female mammal it promotes the transformation, following release of the egg (ovulation), of the graafian follicle into the corpus luteum. FSH production increases when the levels of these hormones are low [2, 3, 4]. Function In Women. In women, FSH is essential to pubertal development and the proper function of the ovaries. FSH also regulates estrogen secretion [5, 6]. When hormone levels fall towards the end of the menstrual cycle, the pituitary gland is stimulated to produce. LH is always present in the body, but a rise in estrogen causes a spike in luteinizing hormone, which triggers ovulation (the release of a female egg cell from an ovary). When to measure LH Ovulation happens at the end of the follicular phase in the menstrual cycle, but unless you know your predicted fertile window , it can be hard to know when to measure for the presence of luteinizing hormone Understanding the function of luteinizing hormone (LH) and its role in reproduction will explain why an LH test is sometimes performed in cases of infertility.LH is gonadotropin. Gonadotropins are hormones that stimulate the reproductive process. LH is also known as lutropin

Luteinizing hormone (LH), follicle-stimulating hormone (FSH) and thyroid-stimulating hormone (TSH) from pituitary and chorionic gonadotropin (CG) from placenta are a family of closely related glycoproteins. Each hormone is a heterodimer, consisting of an alpha- and a beta-subunit FSH is responsible for the first part of follicle maturation and growth which is then spurred on by LH and estrogen. Although many follicles in the ovaries respond to the hormones, only one follicle will fully mature each month. The Female Hormones Estrogen and Progesteron FSH and LH - FSH and LH are secreted by the anterior pituitary in response to gonadotropin-releasing hormone (GNRH) secreted by the hypothalamus. In both males and females, FSH and LH secretion is regulated by a balance of positive and negative feedback mechanisms involving the hypothalamic-pituitary axis, the reproductive organs, and the pituitary and sex steroid hormones

Too little luteinising hormone will also result in infertility in both men and women, as a critical level of luteinising hormone is required to support testicular or ovarian function. In men, an example of a condition where low levels of luteinising hormone are found is Kallmann's syndrome, which is associated with a deficiency in gonadotrophin-releasing hormone secretion from the hypothalamus of FSH and LH as Glycoproteins Regulating Reproduction in Mammalian Species 157 The Asn-linked oligosaccharides of the and -subunits of the glycoprotein hormones, of both pituitary and placental origin, consist of a heterogenous array of neutral, sialylated FSH, follicle-stimulating hormone; LH, luteinizing hormone. The standard of care is testosterone replacement to induce secondary sex characteristics and pubertal growth [ 54 ]. However, the lack of FSH and of sufficient intratesticular testosterone levels results in arrested spermatogenesis and low inhibin B [ 45 , 46 , 53 , 55 ] F SH and LH are two hormones secreted by the pituitary gland in the brain during the menstrual cycle.Blood levels of these hormones are often tested to determine how your ovaries are functioning. FSH (follicle-stimulating hormone) is released when estrogen levels are low.During a regular menstrual cycle, FSH levels begin to rise sharply midcycle, a day or two before ovulation

Luteinizing and Follicle Stimulating Hormones

LH and fsh responsible for ovulation in women at the beginning of menstrual cycle LH and fsh are 5-20 mlU/ml equal in beginning of menstrual cycle and rise of LH that is known as LH surge 25-20 mlU/ml before 24 hour of ovolution and level of LH hormone is slightly degrees after release of eg LH and FSH function. Luteinising and follicle-stimulating hormones control reproductive functioning and sexual characteristics. Stimulates the ovaries to produce oestrogen and progesterone and the testes to produce testosterone and sperm. LH and FSH are known collectively as gonadotropins

Start studying Hormones, functions, and control of secretion. Learn vocabulary, terms, and more with flashcards, stimulates release of follicle- stimulating hormone (FSH)/ stimulates release of luteinizing hormone (LH) *Control of secretion- hypothalamus FSH and/or LH gets too low This test measures the level of follicle-stimulating hormone (FSH) in the blood. FSH plays an important role in sexual development and function. FSH levels that are too high or too low can cause health problems for men and women and delayed or early puberty in children. Learn more These hormones play a role in one or more stages of development and function of the female reproductive system 2. Estrogen. Ovaries produce three varieties of estrogen called estradiol, or FSH and luteinizing hormone, or LH which locally regulate follicular function in the ovary. FSH and LH FSH Levels for Female Fertility. An FSH test is a blood test that measures follicle stimulating hormone to check whether levels are normal, and it is a common part of any infertility workup ordered at a reproductive endocrinology clinic. This hormone test is not done as a urine test. The same blood sample is typically used for FSH testing and to measure several other fertility hormones

PIP: The pituitary-ovarian function of women receiving oral contraceptives (OCs) was studied by measuring basal levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and prolactin, as well as gonadotrophic response to gonadotropin-releasing hormone (GRH). 12 healthy, regularly ovulating women were studied in the early follicular and midluteal phases of the. Stops FSH being produced (so that only one egg matures in a cycle). Repairs, thickens and maintains the uterus lining. Stimulates the pituitary gland to release LH Follicle-stimulating hormone (FSH) is produced in the pituitary gland to control reproductive functions in both men and women. In women, FSH stimulates the growth of ovarian follicles and the production of estradiol during the first half of the menstrual cycle. FSH levels increase after menopause Spermatogenesis is a concerted sequence of events during maturation of spermatogonia into spermatozoa. The process involves differential gene-expression and cell-cell interplay regulated by the key endocrine stimuli, i.e., follicle-stimulating hormone (FSH) and luteinizing hormone (LH)-stimulated testosterone. FSH affects independently and in concert with testosterone, the proliferation. LH and FSH are members of the gonadotropin family. They regulate and stimulate the growth and function of the gonads (ovaries and testes) synergistically. In women, within a control system involving the hypothalamus, anterior pituitary and the ovaries, LH and FSH, are responsible for the cyclical ovarian changes during the menstrual cycle

Structural and Functional Roles of FSH and LH as

If the test result falls in the normal reference range, generally no medical intervention is necessary. In women, the increased levels of FSH and luteinizing hormone (LH) may indicate a condition called primary ovarian failure, where the ovaries fail to function properly.Many conditions such a LH levels in the 1.0 - 3.0 range can be caused by a number of things that can temporarily imbalance hormones such as:Overtraining (endurance)Being significantly under or overweightAlcohol consumptionSpikes in insulinMedications or other drugsHigh stressChronic conditions that can imbalance hormones such diabetes, insulin resistance and various auto-immune disorders can cause borderline or. Gonadotropins are protein hormones secreted by the pituitary gland and include luteinizing hormone (LH) and follicle stimulating hormone (FSH). Both LH and FSH govern the estrous cycle i.e. the cyclical pattern of ovarian activity that facilitates the transition of female animals between periods of reproductive non-receptivity to receptivity enabling mating and subsequent pregnancy

PPT - Brain-Testicular Axis PowerPoint Presentation - ID

Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH) are intimately involved in the control of the growth and reproductive activities of the gonadal tissues, which synthesize and secrete male and female sex hormones. The levels of circulating FSH and LH are controlled by these sex hormones through a negative feedback relationship FSH and LH: FSH or follicle-stimulating hormone and LH or luteinizing hormone are hormones released by the anterior pituitary in response to GnRH (gonadotrophin release hormone) and have functions.

Endocrine Glands

LH and FSH stimulate the gonads to release testosterone or estrogen and progesterone. As these sex hormones circulate in the blood, their rising concentrations are detected by the hypothalamus and pituitary. The sex hormones help to inhibit the release of GnRH, LH, and FSH, which results in decreased sex hormone production and secretion An LH blood test measures the amount of LH in your bloodstream. If you're a woman, the amount of this hormone in your bloodstream varies with age and throughout the menstrual cycle These hormones include thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), and luteinizing hormones (LH)

Follicle-stimulating hormone (FSH) is a glycoprotein gonadotropin secreted by the anterior pituitary in response to gonadotropin-releasing hormone (GnRH) released by the hypothalamus. The pituitary gland also secretes luteinizing hormone (LH), another gonadotropin. FSH and LH are composed of alpha and beta subunits Menotropins are a mixture of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) that are produced in the body by the pituitary gland. Menotropins injection is used in women with healthy ovaries who are enrolled in a fertility program called assisted reproductive technology (ART) Female Hormones. The control of reproduction in females is more complex than that of the male. As with the male, the hypothalamic hormone GnRH (gonadotropin-releasing hormone) causes the release of the hormones FSH (follicle stimulating hormone) and LH (luteinizing hormone) from the anterior pituitary Gonadotrophin-releasing hormone (GnRH) is produced from cells in the hypothalamus.It is then released into small blood vessels that carry the hormone to the pituitary gland.As a consequence, the pituitary gland produces luteinizing hormone (LH) and follicle-stimulating (FSH) hormones. These hormones, LH and FSH, are essential to male and female reproductive health

Follicle-stimulating hormone - Wikipedi

Control of LH production is a complex system involving hormones produced by the gonads (ovaries or testes), the pituitary, and the hypothalamus. Women's menstrual cycles are divided into the follicular and luteal phases, characterized by a mid-cycle surge of follicle-stimulating hormone (FSH) and LH Luteinizing hormone (LH)/testosterone and follicle-stimulating hormone (FSH) are the pivotal endocrine factors controlling testicular functions. The relative importance of either hormone is somewhat different between rodents and primates.

These hormones are produced by different tissues (pituitary and placenta) and their main function is gonadic regulation (ovaries and testicles). The gonadotropins include: FSH ( folliculo-stimulating hormone), LH (luteinizing hormone) and hCG (human chorionic gonadotropin). 2.1.1 Folliculo-stimulating hormone (FSH Difference Between FSH and LH www.differencebetween.com Key Difference - FSH vs LH Follicle stimulating hormone (FSH) and Luteinizing hormone (LH) are commonly referred to as gonadotropins. They involve in the stimulation of germ cells in the production of gametes in both males and females Follicle-stimulating hormone (FSH), one of two gonadotropic hormones (i.e., hormones concerned with the regulation of the activity of the gonads, or sex glands) produced by the pituitary gland.FSH, a glycoprotein operating in conjunction with luteinizing hormone (LH), stimulates development of the graafian follicle, a small, egg-containing vesicle in the ovary of the female mammal; in the male. Luteinizing hormone (LH) is produced and released in the anterior pituitary gland. This hormone is considered a gonadotrophic hormone because of its role in controlling the function of ovaries in females and testes in males, which are known as the gonads

In women of childbearing age, several hormones (LH, follicle-stimulating hormone (FSH), estrogen and progesterone) rise and fall in a specific sequence during each menstrual cycle. Womens' menstrual cycles are divided into follicular and luteal phases, with each phase lasting about 14 days FSH or follicle stimulating hormone helps in the maturing of the egg inside the follicle. LH or luteinizing hormone comes into play once the egg is mature inside the follicle. In one of the endless miracles of the human body, a surge of LH hormones causes the release of this egg from inside the ovary

FSH is follicle stimulating hormone and LH is leutinizing hormone. FSH is important because it can predict a woman´s fertility potential. As a woman gets older, the number of eggs that she has in her ovaries decreases and the quality of those eggs decrease Follicle stimulating hormone (FSH): In males, FSH regulates spermatogenesis (formation of sperms) and in females, FSH stimulates growth and development of ovarian follicles and secretion of estrogen hormone. Luteinizing hormone (LH): In males, LH is also called ICSH (interstitial cell-stimulating hormone) which stimulates testes to synthesize. pituitary. It has long been recognized that reproductive function is closely associated with energy balance, and metabolic dysregulation is linked with reproductive abnormalities (Lu et al.,2008). Compare the differences in levels of adiponectin, FSH, LH, testosterone and estradiol between the diabetic patients and control group and in diabeti These hormones regulate the gonads (testes in males and ovaries in females) and therefore are called gonadotropins. In both males and females, FSH stimulates gamete production and LH stimulates production of hormones by the gonads. An increase in gonad hormone levels inhibits GnRH production through a negative feedback loop

The effects the four hormones estrogen, progesterone, follicle stimulating hormone (FSH), and luteinizing hormone (LH) have on your body. Although many women take it for granted that their ovaries play an important role in the female reproductive system, the majority of them do not understand how essential their ovaries are to the proper functioning of the female body As with the male, the anterior pituitary hormones cause the release of the hormones FSH and LH. In addition, estrogens and progesterone are released from the developing follicles. Estrogen is the reproductive hormone in females that assists in endometrial regrowth, ovulation, and calcium absorption; it is also responsible for the secondary sexual characteristics of females GnRH specifically binds to the GnRH receptor (GnRH-R), mainly expressed on the surface of gonadotropins cells in the pituitary and stimulates the release of gonadotropin hormones LH and FSH (Kakar et al., 1992).This binding results in the stimulation of pituitary gonadotropin release that regulate sperm and ovum maturation and steroidogenesis in the gonads (Harrison et al., 2004)

FSH is secreted from cells in the anterior pituitary gland and acts synergistically with LH (Luteinizing Hormone) in reproduction. These hormones are at their lowest levels late in the follicular phase, and at the end of the luteal phase there is a slight increase, which is necessary to begin the next ovulatory cycle These hormones binds to cell surface receptors and stimulates the release of certain molecules (secondary messengers) to perform biochemical functions; On the basis of secondary messengers group II hormones are of 3 types; i. Secondary messenger is cAMP: eg. Adrenocorticotropic hormone, FSH, LH, PTH,ADH, calcitonin, glucagon, ii

What are the functions of LH, GnRH, and FSH in the male

Lack of complete separation of follicle-stimulating hormone (FSH, follitropin) and luteinizing hormone (LH) suggested that one gonadotropin may exist with dual activity. The development of the human chorionic gonadotropin (hCG) augmentation assay for FSH (Steelman and Pohley, 1953) and the ovarian ascorbic acid depletion test for LH (Parlow, 1961) further accelerated the purification of FSH. Men with a selective decrease of LH and FSH without any apparent cause, and with normal function of the other pituitary hormones, are categorized as having isolate gonadotropin deficiency or idiopathic hypogonadotropic hypogonadism. In Kallman syndrome (classic hypogonadotropic hypogonadism) FSH, testosterone and LH levels will be low. Women FSH is Follicle Stimulating Hormone, and it is produced by the brain (via the pituitary gland) to stimulate follicles in the ovary to grow. When the brain realises that there is low E2 around (ie at the time of a period), and a further group of follicles should be recruited to start another cycle, the blood level of FSH rises, but generally to not more than 9iu/l LH produceras i hypofysen. Om du är kvinna är LH en viktig del av din menstruationscykel. Hormoner fungerar tillsammans med follikelstimulerande hormon (FSH), vilket är en annan gonadotropin gjord i hypofysen. FSH stimulerar äggstocksfollikeln, vilket gör att ägget växer. Det utlöser också produktionen av östrogen i follikeln

Abstract. There has been much debate about the role of luteinizing hormone (LH) during follicle stimulating hormone (FSH)-treated ovarian stimulation for assisted reproduction, where the endogenous LH is suppressed using a gonadotrophin-releasing hormone analogue Inhibitory hormone that prevents release of hormones such as growth hormone from the anterior pituitary: Gonadotrophin releasing hormone (GnRH) Anterior pituitary: Stimulates release of follicle stimulating hormone (FSH) and luteinising hormone (LH) from the anterior pituitary: Corticotrophin releasing hormone (CRH) Anterior pituitar It is my understanding that an FSH level higher than 10-15mIU/L is what doctor's believe may indicate diminished fertility or diminished ovarian reserve, but that normal FSH levels during the follicular and luteal phase should range between 5 and 20 IU/L. Test results should be within that 5-20 IU/L range if hormones are balanced and reproductive organ function optimal Several hormones. are involved in the menstrual cycle. of a woman: follicle stimulating hormone (FSH) causes the maturation of an egg in the ovary luteinising hormone (LH) stimulates the release.

Difference between FSH and LH Major Difference

FSH is one of the gonadotrophic hormones - the other being Luteinizing Hormone (LH). FSH is essential in pubertal development and in the function of women's ovaries and men's testes[5]. Low FSH levels can have a significant effect on a woman's reproductive system - it can result in incomplete development at puberty and poor ovarian function; each of which may lead to infertility[6] FSH and LH - General Info. FSH (follicle-stimulating hormone) and LH (luteinizing hormone) are two vital hormones for proper process of fertilization. They can be normal, reduced or increased and apart from being tested in case of infertility they are also used in diagnosing pituitary disorders Most of the hormones of our body are secreted from pituitary gland, Anterior pituitary secreates FSH, LH, ACTH, GNRH, Prolactin, Adrenal Gland Function - Duration: 4:30 The luteinizing hormone test is usually accompanied by a test to measure the FSH levels in blood, because both these hormones are essential for the reproductive system, and a deep analysis of the patient's symptoms, his/her general health, and the hormonal profile will help a doctor understand the real problem causing abnormality in the LH levels, and, thus, determine the right line of.

Luteinizing hormone - Wikipedi

Gonadotropin-releasing hormone (GnRH) is a releasing hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary.GnRH is a tropic peptide hormone synthesized and released from GnRH neurons within the hypothalamus.The peptide belongs to gonadotropin-releasing hormone family.It constitutes the initial step in the hypothalamic. FSH stimulated ovarian follicular development and caused sexual maturity in immature rats, and LH had no effect when given alone but caused follicles that were stimulated by FSH to luteinize. When given together, these two hormones accounted for all of the ovarian effects of the pituitary extracts (Goodman, 2004) Synthesis and release of pituitary hormones luteinising hormone (LH) and follicle stimulating hormone (FSH) is under the control of gonadotrophin releasing hormone from the hypothalamus, and modulated by circulating gonadal steroids. These tests are therefore used routinely to assess the hypothalamo-pituitary-gonadal axis

Relationship of FSH, LH, DHEA and Testosterone Levels in Seminal Plasma with Sperm Function Parameters in Infertile Men December 2017 Merit Research Journal of Medicine and Medical Sciences 5(12. A luteinizing hormone (LH) test is a blood or urine test that measures the levels of LH in a person's blood. This hormone plays a key role in the reproductive system of both males and females FSH or follicle stimulating hormone is a crucial hormone for regulating the reproductive processes of the body. In women older than 45 years, high FSH levels may indicate an impending menopause. Know more about the relation between FSH levels and menopause in this article Luteinizing hormone (LH) is a hormone associated with reproduction and the stimulation of the release of an egg from the ovary (ovulation) in women and testosterone production in men. This test measures the amount of luteinizing hormone in the blood or urine. LH is produced by the pituitary gland, a grape-sized organ found at the base of the brain

Endocrine System Flashcards | Easy Notecards

Follicle stimulating hormone (FSH) is often used in conjunction with other tests (LH, testosterone, oestradiol and progesterone) in the investigation of infertility in both men and women.FSH levels are also useful in the investigation of menstrual irregularities (irregular periods) and to aid in the diagnosis of pituitary gland disorders Follicle-stimulating hormone (FSH) is released by the pituitary gland in both men in women. The role of FSH in women is different from its role in men, because it controls the menstrual cycle in females. The amount of FSH changes during the cycle and is usually highest just before ovulation occurs. This hormone works in conjunction with luteinizing hormone (LH) to release the right amount of. An LH test works closely with another hormone called follicle-stimulating hormone (FSH) to control sexual functions. So an FSH test is often done along with an LH test. These tests are used in different ways, depending on whether you are a woman, man, or child. In women, these tests are most often used to Most hormone testing (estradiol, FSH, LH, TSH, prolactin) can be done at any time of day, but blood for testosterone levels should be drawn between 7:00 and 9:00 a.m., as this is when most men have their highest blood levels of testosterone hormone (FSH) Protein (1) Follicle growth (2) Estrogen release (3) Spermatogenesis Luteinizin g hormone (LH) Protein (1) Ovulation (2) Corpus luteum formation and function (3) Testosterone release Prolactin Protein (1) Milk synthesis Adrenocorticotropin (ACTH) Polypeptide (1) Release of glucocorticoi Control of LH production is a complex system involving hormones produced by the gonads (ovaries or testes), the pituitary gland and the hypothalamus, such as gonadotrophin-releasing hormone (GnRH). Women's menstrual cycles are divided into 2 phases, the follicular and luteal, by a mid-cycle surge of follicle-stimulating hormone (FSH) and LH
