    Causes of Male Infertility

    Discover The Reasons Behind Male Infertility

    Male infertility occurs when abnormalities in sperm production, function, or delivery reduce the likelihood of achieving pregnancy. Understanding the underlying causes is essential for accurate diagnosis and appropriate treatment planning. 

    • Sperm Production Problem

      Conditions affecting sperm production within the testes are among the most common causes of male infertility. These may result in low sperm count, poor sperm movement, or abnormal sperm shape. Contributing factors include:

      • Hormonal imbalances
      • Genetic conditions
      • Infections
      • Exposure to toxins, radiation, or certain medications
    • Obstruction of Sperm Transport

      Blockages within the male reproductive tract can prevent sperm from being present in the ejaculate despite normal sperm production. Obstructive causes may involve:

      • Congenital absence or blockage of the vas deferens
      • Infections or inflammation causing scarring
      • Previous surgeries affecting the reproductive tract
    • Sexual Disorders and Functional Issues

      Blockages within the male reproductive tract can prevent sperm from being present in the ejaculate despite normal sperm production. Obstructive causes may involve:

      • Congenital absence or blockage of the vas deferens
      • Infections or inflammation causing scarring
      • Previous surgeries affecting the reproductive tract
    • Hormonal Imbalances

      Hormonal disorders involving the hypothalamus, pituitary gland, or testes can interfere with sperm production. Conditions affecting testosterone, follicle-stimulating hormones, luteinizing hormone levels may lead to reduced sperm quantity or quality.

    • Sperm Antibodies

      Sometimes, the body’s immune system mistakenly identifies sperm as a “foreign invader” and creates antibodies to attack them. This can happen after a vasectomy, an injury, or an infection in the epididymis.
