Introduction
Spermatogenesis
- occurs throughout adult life
- spermatagonia derived from a long series of mitoses, with 1012 sperm produced in a lifetime. This provides the opportunity for new mutation
- process takes 64 days
Testosterone produced by the fetal testes is responsible for the development of the male genitalia and then declines to close to 0 until puberty.
During puberty, release of LH from the anterior pituitary stimulates the testes to begin testosterone production again.
Testosterone regulates the development and normal functioning of sperm, the male reproductive organs, and the male sex drive. It is also contributes to muscle and bone growth during puberty.
