Male Infertility -- 4 Main Types

Male infertility can be classified into four main types:

  • No sperm (azoospermia) accounts for 3-4% of male infertility.
  • Quantity or quality. This subgroup may account for about 90% of male infertility:
    • Quantity: Poor sperm quantity (oligospermia)
    • Quality :
      • low motility (asthenozoospermia)
      • a high percentage of abnormal sperm (teratozoospermia)
      • Antisperm antibodies, etc.
  • Sperm dysfunctional, where there is a normal semen analysis, but the sperm lack or have a defective fertilizing capacity, resulting in complete failure of fertilization or poor fertilization of the eggs in IVF. This accounts for 3-6% of male infertility.
  • Inability to ejaculate into the vagina. This accounts for 4-6% of male infertility.
