Causes of male infertility

  • The sperm's exit route is blocked (from birth, by scarring from infection, past vasectomy, etc.)
  • Retrograde ejaculate (semen is ejaculated backwards, into the bladder)
  • Sperm production in the testes is low or absent (there can be many causes for this finding)
  • Oligospermia, Azoospermia (when sperm count is too low, sperm has a much lower chance of reaching and fertilizing the egg, leading to infertility)
  • TESE
  • Klinefelter syndrome
  • Vasectomy (can be considered a cause of male infertility, if the male partner changes his mind about having children after having had a vasectomy)
  • Varicocele
  • Blockage in a man's reproductive system
  • Certain medications
  • Spinal cord injury
