Study Notes

Male Reproductive System

  • Structure: Bulbourethral glands

  • Description (Structure, Function, Location): Small glands below the prostate gland; secrete a lubricating fluid to neutralize acidity in the urethra prior to ejaculation.

  • Structure: Ejaculatory ducts

  • Description (Structure, Function, Location): Ducts formed by the union of the vas deferens and seminal vesicles; transport semen to the urethra during ejaculation.

  • Structure: Epididymis

  • Description (Structure, Function, Location): A coiled tube located on the posterior side of the testes; stores and matures sperm cells before ejaculation.

  • Structure: Penis

  • Description (Structure, Function, Location): The external male organ for sexual reproduction; delivers semen into the female reproductive tract and allows for the excretion of urine.

  • Structure: Prostate gland

  • Description (Structure, Function, Location): A gland located below the bladder; secretes a fluid that contributes to semen, enhancing sperm motility and viability.

  • Structure: Scrotum

  • Description (Structure, Function, Location): A pouch of skin and muscle containing the testes; regulates the temperature necessary for optimal spermatogenesis.

  • Structure: Seminal vesicles

  • Description (Structure, Function, Location): Glands located behind the bladder; produce a sugary fluid that provides energy for sperm and makes up the bulk of semen.
