The major hormones in the male reproductive system are:
1. Gonadotropin Releasing Hormone (GnRH) is mainly made in the hypothalamus from where it travels to the pituitary gland where it stimulates the synthesis and secretion of the gonadotropins which are follicle-stimulating hormone and luteinizing hormone.
2. Follicle Stimulating Hormone (FSH) is released by the anterior pituitary gland. It is necessary for the maturation of spermatozoa.
3. Luteinizing Hormone (LH) is released by the anterior pituitary gland. In the testes, LH
stimulates the synthesis and secretion of testosterone. It also stimulates the testes to produce the hormone androgen.
4. Testosterone is made in the interstitial cells. It stimulates the sex drive.
5. Inhibin is made by the Sertoli cells when they are low in nutrients in order to feed developing sperm cells. It acts as a negative feedback, going to the brain to slow the release of FSH and GnRH.
Gonadtrophin Releasing Hormone is released by hypothalamus. Has effect on Anterior Pituitary Gland causing it to begin releasing Leutinising hormone and Follicle Stimulating Hormone.
Leutinsing Hormone acts on the Leydig cells in the testes and they begin secreting Testosterone the main male sex hormone. Testosterone and FSH both affect Sertoli Cells in the Testes and the production of sperm is initiated.
In humans, spermatogenesis is triggered by Follicle Stimulating Hormone (FSH) and Testosterone
That is the hormone, Testosterone.It is secreted by testis.
Testosterone is the hormone which regulates spermatogenesis.It is produced by testis.
Follicle Stimulating Hormone (FSH)
testosterone
Testosterone, produced by the testes, stimulates spermatogenesis.

Hormone
The Pituitary produces: 1. Leutenizing Hormone. 2. Follicle Stimulating Hormone. In both males and Females. However, their acitions are different in the sexes. In males: Leutenizing hormone in males stimulates testes to secrete Testosterone. Follicle stimulating Hormone brings about Spermatogenesis.
Secretin is a hormone released by the small intestine. Like insulin, the presence of food in the stomach triggers it to release secretin which in turn triggers the pancreas and liver to release bile and pancreatic juice for food breakdown and absorption.
In men, follicle stimulating hormone starts spermatogenesis. This hormone is also abbreviated FSH.
LH(Leutenizing Hormone) hormone induces the process of spermatogenesis.
Spermatogenesis is stimulated dy FSH.Other hormone is LH
Testosterone, produced by the testes, stimulates spermatogenesis.

Inhibin
the hormone FSH ( Follice Stimulating Hormone) triggers the menses (period) in a healthy female. During the menses, the uterine lining is being shed.
It acts on inferior pitutory.It triggers secretion of growth hormone.
GnRH
luteinizing hormone
