The testicular reproductive system encompasses the structures and functions of the testes, which are responsible for producing sperm and testosterone. It is a crucial aspect of male fertility and hormonal balance.
congrats on reading the definition of testicular reproductive system. now let's actually learn it.
The testes produce sperm through a process called spermatogenesis, which occurs in the seminiferous tubules.
Testosterone production in the testes is regulated by luteinizing hormone (LH) from the anterior pituitary gland.
The interstitial cells (Leydig cells) within the testes are primarily responsible for testosterone secretion.
Testicular function can be affected by various drugs, including anabolic steroids and certain chemotherapy agents, impacting both fertility and hormone levels.
Conditions such as testicular torsion or infections like orchitis can severely impact testicular health and function.
