|
Seminiferous Tubules |
Make male gametes |
Sperm |
|
|
Sertoli Cells |
Nourish & protect sperm. Inside seminiferous tubules |
|
|
|
Interstitial Cells |
Produce testosterone |
|
|
|
Epididymis |
Sperm storage and maturation |
|
|
|
Vas Deferens |
Passage from epididymis to urethra |
|
|
|
Ejaculatory Duct |
Connects vas deferens & urethra, passes through the prostate |
|
|
|
Urethra |
Conducts urine & semen out of the body |
|
|
|
Seminal Fluid |
Sperm & fluid are secreted from accessory glands |
|
|
|
Accessory glands |
Prostate gland & Cowper's gland: alkaline & mucoid fluids Seminal vesicles: fructose (energy), also, mucoid & alkaline |
|
|
|
Impotency |
Difficulty maintaining erection -Caused by damage to the parasympathetic nerves or hormonal imbalances; psychological problems |
|
|
|
Testes |
Endocrine glands -Interstitial cells secrete testosterone & androsterone -both anabolic (muscle-building) and androgenic (reproductive) effects |
|
|
|
Testosterone |
-stimulates spermatogenesis -influences development of puberty & secondary sex characteristics -enhances sex drive |
|
|
|
Lutenizing Hormone (LH) |
Cause interstitial cells to produce testosterone |
|
|
|
Follicle Stimulating Hormone (FSH) |
(With testosterone) sertoli cells stimulate sperm production |
|
|
|
Gonadotropin Releasing Hormone |
Causes LH and FSH release |
|
|
|
Negative Feedback |
-testosterone inhibits GnRH release -sertoli cells release inhibin which also inhibits GnRH release |
|
|
|
Male Birth Control Pill |
Prevents FSH from stimulating Sertoli cells - inhibits sperm production |
|
