Why is it important to be evaluated for Male Factor Infertility?

Infertility is defined as the inability to achieve a pregnancy after 12 months of unprotected intercourse. Over 50% of the time, this is related to a male factor problem. An initial evaluation should include a semen analysis, and if this is found to be abnormal, a referral to a reproductive urologist is recommended. The first step in evaluation involves a review of the patient's history and a physical examination. The comprehensive urologic evaluation is important because it can possibly identify significant and potentially treatable conditions such as testis cancer or other significant medical conditions such as diabetes, genetic abnormalities, etc. that may be impacting fertility. This concept was first identified by Dr. Honig and others in a paper dating back to 1994.

Are there treatable or reversible causes of Male Factor Infertility?

Absolutely.  A thorough history and physical examination may identify factors that can affect fertility potential. These factors can include smoking, alcohol, testosterone use, and marijuana. In addition, a physical examination may identify enlarged veins called varicoceles that can be treated to improve semen quality. Blood tests may be also recommended to identify hormone imbalances or genetic abnormalities.

How can I better understand my semen analysis results?

Dr. Honig will review your semen analysis results in detail. All parameters of a semen analysis are important, including semen volume, sperm concentration, motility, and sperm morphology (or sperm shape).
