The Male Partner

Common Problems related to the male partner are:
  • Anatomic abnormalities, which obstruct the passage of sperm into the ejaculate; or lack of proper development of the internal reproductive organs
  • Hormonal abnormalities, where certain imbalances can affect the ability to produce sperm
  • Abnormal dilation, or expansion, of the veins in the testicle; also known as a varicocele, this abnormality is found in approximately 25-35 percent of infertile males during a physical examination.
