Study Notes
Male Reproductive System
- The male reproductive system comprises the testes, genital ducts, accessory glands, and the penis.
- Testes produce sperm and hormones, including testosterone.
- Testosterone drives male reproductive function.
- Testosterone is crucial for:
- Spermatogenesis (sperm production)
- Sexual differentiation during embryonic and fetal development
- Regulating pituitary gland hormone secretion.
- Dihydrotestosterone (a testosterone metabolite) is also essential.
- Dihydrotestosterone affects tissue development, specifically male accessory glands and hair follicles during puberty.
- Genital ducts and accessory glands produce secretions vital for sperm function.
- These secretions propel sperm and provide them with necessary nutrients within the male reproductive tract.
- Semen is a combination of sperm and secretions from accessory glands.
- Semen is introduced into the female reproductive tract by the penis and contains needed nutrients for sperm.
- Sperm movement and secretions are propelled via muscular contractile activity, including within the penile urethra.
