In the male, the principal sex hormones are the androgens, of which testosterone is the most important. The androgens are steroid hormones produced mainly by the Leydig cells(interstitial cells located near the seminiferous tubules) of the Testes. Testosterone and other androgens are directly responsible for the primary and secondary sex characteristics of the male. In addition to specific sexual behaivor and sex drive the androgens also increase general agressiveness, and are respnsible for vocal behaivor such as singing in birds and calling in frogs. With the hormonal control of the male system the Gonadotropin-releasing hormone (GnRH) from the hypothalamus stimulate the anterior pituitary to secrete two gonadotropic hormones with different effects on the testes. One hormone is luteinizing hormone (LH) which acts on the Leydig cells which produce androgens mainly testosterone. The other hormone is follicle stimulating hormone (FSH) which acts on Sertoli cells that nourish developing sperm cells this in turn will produce sperm.

Male reproductive functions are controlled mainly by hormones from the hypothalamus and?
Male reproductive functions are controlled mainly by hormones from the hypothalamus and pituitary gland. These hormones stimulate the production of testosterone in the testes, which is responsible for sperm production, sex drive, and secondary sexual characteristics. The hypothalamus releases gonadotropin-releasing hormone (GnRH), which triggers the pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH) to regulate testosterone production.
Hypothalamus produces hormones secreted by which gland?
The hormones produced by the hypothalamus are secreted by the pituitary gland. The hypothalamus regulates the pituitary gland by releasing hormones that stimulate or inhibit hormone production in the pituitary.
What will Hypoglycemia will stimulate the production of?
Hypoglycemia stimulates the production of hormones like glucagon and epinephrine. These hormones help to increase blood sugar levels by promoting the breakdown of glycogen stores in the liver, as well as stimulating the release of glucose into the bloodstream.
The male sex hormones that stimulate development of male sexual characteristics are known as?
androgens. The main androgen produced in males is testosterone. It plays a crucial role in sperm production, deepening of the voice, growth of facial and body hair, and muscle mass development.
Function of inhibin hormones in males?
In males, inhibin hormones are produced by the testes and act to regulate the production of follicle-stimulating hormone (FSH) from the pituitary gland. Inhibin helps to provide negative feedback to the pituitary gland to reduce FSH secretion, which in turn helps to regulate the production of sperm in the testes.
How the sperm is secrete?
Sperm is produced in the testes through a process called spermatogenesis. The testes secrete hormones that stimulate this production. Once sperm are fully formed, they are released through ejaculation during sexual intercourse.
What gland produces hormones that stimulate the production of T-cells?
Thymus gland
What are two hormones that stimulate white blood cell production?
boner juice
What gland produces hormones that stimulate the production T cells?
Thymus gland
What development leads to abnormal production of breast milk?
Any condition that upsets the balance of hormones in the blood or the production of hormones by the pituitary gland or sexual organs can stimulate the production of prolactin.
What substances are involved in controlling the production of sperm and eggs in humans?
hormones
What substances involved in controlling the production of sperm and eggs in humans?
hormones
Why do hormones affect some organs but not others?
Because hormones have specific hormone binding sites to act
What two hormones stimulate production of all other sex hormones during adolescence?
The two hormones that stimulate the production of all other sex hormones during adolescence are luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are released by the pituitary gland. These hormones act on the gonads (ovaries in females and testes in males) to promote the production of estrogen and testosterone, which are responsible for the development of secondary sexual characteristics.
What hormones intiate sperm production?
FSH it is produced by the potouatarey gland in the brain
What is secreted by the anterior pituitary to stimulate sperm cell production?
It is probably Follicle stimulating hormone.
What are almond shaped male glands responsible for the production of sperm and male hormones?
testes
