Biology-Male Reproductive Organs

carries sperm to the penis during ejaculation

Vas deferens

Prostate gland

adds alkaline fluids that neutralise vaginal acids

Urethra

carries urine during excretion and semen during ejaculation

Penis / erectile muscle

becomes erect to increase chances of sperm reaching the top of the vagina

Seminal vesicle

adds nutrients (fructose for respiration) and mucus to protect sperm

Epididymis

sperm mature, gain mobility, and are stored until ejaculation

Testis (testes)

produces millions of sperm daily and secretes testosterone

Scrotum

supports and protects testes by keeping them at a lower temperature outside the body

Cowper's gland (bulbourethral gland)

secretes mucus to lubricate sperm transport and neutralise vaginal pH

Bladder

collects urine from kidneys and releases it when full
