In men, FSH helps control the production of sperm and the amount of FSH in men normally remains stable after puberty.
In men, LH stimulates testosterone production from the interstitial cells of the testes (Leydig cells). FSH stimulates testicular growth and enhances the production of an androgen-binding protein by the Sertoli cells, which are a component of the testicular tubule necessary for sustaining the maturing sperm cell.
FSH in Males
In men, it stimulates testicular growth and helps produce a protein that plays a vital role in male fertility by aiding in the creation of normal sperm cells and maintaining them until they are ready to be released.
LH induces the proliferation and maturation of interstitial Leydig cells which will secrete T. FSH acts on the Sertoli cells (SC) of the seminiferous tubules by stimulating the production of signaling molecules and metabolites necessary for spermatogenesis.
Follicle-stimulating hormone (FSH) is released by the anterior pituitary gland. Its presence in males is necessary for the maturation of spermatozoa. Follicle-stimulating hormone stimulates both the production of androgen-binding protein by Sertoli cells and the formation of the blood-testis barrier.
For men or people AMAB, FSH stimulates sperm production. In collaboration with testosterone inside the testes, which is triggered by LH, FSH also sustains sperm production.
As in women, gonadotropin releasing hormone, or GnRH, is released in a pulsatile fashion, stimulating the release of follicle stimulating hormone (FSH) and leutinizing hormone (LH). In men, LH primarily stimulates testosterone production, while FSH stimulates the production of sperm.
Through interaction with its receptor (FSHR) [9], FSH acts on its unique target in male cells, namely, the Sertoli cells, located at the basis of the seminiferous tubules of the testis [10,11]. These cells create a niche in which spermatogonia proliferate and mature [10,11].
High FSH levels in men may mean the testicles are not functioning correctly due to: Advancing age (male menopause) Damage to testicles caused by alcohol abuse, chemotherapy, or radiation. Problems with genes, such as Klinefelter syndrome. Treatment with hormones.
LH in males stimulates the Leydig cells to release androgens. In females, LH result in ovulation. FSH in males stimulates the Sertoli cells to release factors for spermiogenesis but in the case of females, it helps to control the menstrual cycle and stimulates the growth of eggs in the ovaries.

How do low LH and FSH affect male fertility? Both LH and FSH are vital to the proper production of sperm. Low levels of these hormones can be at least partly responsible for low sperm counts, which is the biggest cause of infertility in men. Normally, diagnosis would begin with a semen analysis.
Elevated LH and FSH levels suggest primary hypogonadism, whereas low or low-normal LH and FSH levels suggest secondary hypogonadism. Normal LH or FSH levels with low testosterone suggest primary defects in the hypothalamus and/or the pituitary (secondary hypogonadism).
However, if the FSH is low (<1.0 mIU/mL), then the testicles may not receive the necessary signal from the pituitary gland, and decreased sperm production can result even if the testicular sperm production “machinery” is normal.
In patients with hypogonadotropic hypogonadism, male infertility is due to the lack of stimulation of spermatogenesis by the gonadotropins FSH and luteinizing hormone (LH).
Testosterone (T) replacement therapy causes suppression of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) that can lead to decrease in semen parameters and possible infertility. Different T formulations may have varying suppression on FSH and LH.
The most common cause of low FSH levels in men is the use of testosterone or steroids. These tell the brain that your body is producing enough Testosterone, causing it to shut down its natural production and, consequently, your body stops producing FSH.
In men presenting with low FSH levels leading to secondary hypogonadism or high FSH levels resulting from primary hypogonadism, the history reveals erectile dysfunction, decreased libido, infertility, and low energy. In those with hyperprolactinemia, galactorrhea and/or gynecomastia may be present.
Primary hypogonadism is associated with low levels of testosterone and high-normal to high levels of LH and FSH. Secondary hypogonadism is associated with low levels of testosterone and normal to low levels of LH and FSH.
In multiple linear regression analysis, FSH and LH were inversely associated with sperm concentration, motility, and morphology. Inhibin B and free T4 were positively associated with sperm concentration, while there was a suggestive positive association between testosterone and sperm motility.
The rise in FSH and LH with increasing age is consistent with the decline in testosterone, assuming normal operation of the feedback pathway by which low testosterone level signals the hypothalamic-pituitary axis to release FSH and LH.
Occasionally, male infertility can be due to a decrease or absence in the production of two hormones essential for sperm production: follicle stimulating hormone (FSH) and luteinizing hormone (LH).
No, masturbating won't cause you to have a low sperm count or affect your ability to have children. Masturbating is normal and healthy. And it's totally okay to masturbate a lot – even more than once a day.
GnRH stimulates the pituitary gland to produce follicle stimulating hormone (FSH), the hormone responsible for starting follicle (egg) development and causing the level of estrogen, the primary female hormone, to rise.
Testosterone is indispensable for sperm production, however both testosterone and Follicle Stimulating Hormone (FSH) are needed for optimal testicular development and maximal sperm production.
