Question

human male reproductive system

Answer 1

Hormones which control reproduction in males are:


Gonadotropin-Releasing Hormone (GnRH):

The hypothalamus secretes this hormone into the pituitary gland in the brain.

There are two gonadotropic hormones, FSH and LH.

Luteinizing Hormone (LH):

The pituitary gland secretes this hormone after receiving a GnRH signal from the hypothalamus.

LH stimulates Leydig cells, in the testes, telling them to produce testosterone.

Follicle-Stimulating Hormone (FSH):

The pituitary gland also secretes this hormone.

Testosterone helps FSH run through the bloodstream to make Sertoli cells, located in the seminiferous tubules of the testes, to make immature sperm to mature sperm.
