Androgen Hormone Definition
Androgen hormones are a group of hormones that are responsible for the development and maintenance of male sex characteristics. These hormones include testosterone and androstenedione. Androgen hormones are produced in the testes and the adrenal glands. They are responsible for the development of the penis and testes, the growth of pubic and facial hair, and the production of sperm.
Sertoli Cells
The Sertoli cells are found in the testes and play a key role in the development and maintenance of the male reproductive system. They are responsible for producing the hormone testosterone and for nurturing and developing the sperm cells. The Sertoli cells also help to transport the sperm cells from the testes to the penis during ejaculation.
Testes and Their Hormones
The testes are a pair of organs located in the scrotum that produce sperm and testosterone. The testosterone produced by the testes is responsible for the development of male sex characteristics, such as the growth of facial hair and the deepening of the voice.
Testosterone Functions
Testosterone is a hormone that is produced primarily by the testes in men and the ovaries in women. It is responsible for the development of male sex characteristics, including the growth of body hair, the deepening of the voice, and the increase in muscle mass. Testosterone also plays a role in the production of sperm.
Disorders of Testosterone
There are a number of disorders that can affect testosterone levels. These can include anything from problems with the testicles themselves, to issues with the pituitary gland that controls testosterone production.
One common disorder of testosterone is known as hypogonadism. This occurs when the body is unable to produce enough testosterone. This can be due to a problem with the testicles, or with the pituitary gland.
Another common disorder is known as hypergonadism. This occurs when the body produces too much testosterone. This can be due to a problem with the testicles, or with the pituitary gland.
Both hypogonadism and hypergonadism can cause a number of symptoms, including changes in sex drive, changes in mood, and changes in body composition.
Spermatogenesis
Is the process of sperm production. In males, it occurs in the testes. Spermatogonia, the initial cells in the process, divide to form spermatocytes. These cells then undergo meiosis to form four sperm cells. These sperm cells then travel through the epididymis and are ejaculated during orgasm.
Spermatogenesis is the process of sperm production. The process begins with the formation of spermatogonia, the cells that give rise to sperm. These cells are located in the testes and are located in the seminiferous tubules. The spermatogonia divide to form spermatocytes. These cells then divide to form sperm.
