Q

Familiarize the detailed flow of sperm production to ejaculation

A
  1. Sperm develop as tiney round cells in seminiforous tubules of testicles
  2. Hormones from testicles and pituitary gland help sperm mature
  3. They travel to epididymis and develop further for several weeks
  4. Migration to vas deferens
  5. Travel to seminal gland, nourished by semen fluid
  6. Travel to prostate gland and mix with prostate fluids
  7. Exit through urethra during ejaculation
