Q

SERIES OF STAGES OF EJACULATION

A
  1. Sperm is FORCEFULLY MOVED from the epididymis through the vas deferens through peristalsis during orgasm.
  2. Sperm ENTERS THE EJACULATROY DUCT, where it receives fluid from the prostate and seminal vesicles.
  3. ADDITIONAL FLUID is added by the bulbourethral gland.
  4. The urinary sphincter CLOSES OFF THE BLADDER.
  5. The SEMEN EXITS the body via the urethra in the penis.
