1
, Functions:
Testis
• Produces sperm cells by meiosis.
• Produces the male hormone testosterone.
Seminiferous Tubules
• Site where sperm production (spermatogenesis) takes place.
Epididymis
• Stores sperm temporarily.
• Allows sperm to mature and become motile.
Vas Deferens (Sperm Duct)
• Transports sperm from the epididymis to the urethra.
Seminal Vesicles
• Secrete a fluid rich in fructose.
• Nourishes sperm and provides energy for movement.
• Contributes to the formation of semen.
Prostate Gland
• Produces an alkaline fluid.
• Neutralises the acidity of the urethra and vagina.
• Improves sperm survival and motility.
Cowper's (Bulbourethral) Gland
• Secretes an alkaline mucus.
• Neutralises traces of acidic urine in the urethra.
• Lubricates the urethra before ejaculation.
Urethra
• Passage through which semen and urine leave the body.
• NB: Semen and urine do not pass through simultaneously.
Penis
• Copulatory organ.
