Approximately 40% of infertility problems are associated with male factor etiologies. Production of sperm can be injured or impaired by testicular injuries, surgery, infection, allergies, toxins, undescended testes, varicoceles, drugs, hernia, and athletics. It is well worth the time to ask questions regarding these factors at the time of an infertility evaluation.

When patients are sent for a semen analysis, we ask them to abstain from intercourse for two to three days and recommend that a sample be obtained by masturbation in the clinic. If it is collected at home, it needs to arrive in two hours and should be kept at body temperature. We consider a normal semen sample to have a volume of 2 to 6 ml, a pH between 7 and 8, a count greater than 20 million per milliliter, and a morphology of greater than 60% normal.

Many causes of infertility are amenable to treatment (e.g., surgery repair of varicocele or for obstruction of the vas deferens). In men with a lower-than-normal sperm count or other defects, intrauterine insemination to improve and concentrate the sperm are available.

Assisted reproductive techniques such as in vitro fertilization with intracytoplasmic sperm injection are also options that are available to couples abnormalities of sperm parameters.
