Causes of Infertility

In about 80% of the cases, the cause of infertility can be identified after a comprehensive fertility work-up. Approximately 1/3 of the causes are attributed to the male, 1/3 are attributed to the female and 1/3 are attributed to a combination of problems that stem from both the male and female. Male factor infertility can be caused by problems with sperm function, sperm production, sperm transport and / or sexual dysfunction. Prior vasectomy is common condition that easily can be treated. Typically, most male infertility factors are related to malformed sperm (teratospermia), poor sperm motility (asthenospermia), or low sperm count (oligospermia). Additional common causes include the complete lack of sperm in the ejaculate (azoospermia), which might be caused by the abnormal transport of sperm or a lack of sperm altogether. A comprehensive evaluation of the male partner is a vital part of the initial infertility work-up. Common causes of female factor infertility can include the blockage of the fallopian tubes, failure to ovulate (release of the egg), and ovarian dysfunction or failure. Abnormalities of uterine function and pelvic conditions including endometriosis can cause complications with normal conception. A thorough work-up of the female will identify many of these issues.

A couple’s problems are often related to the combination of various factors. Sometimes several mild defects combine to prevent reproduction or make it ineffective.
