Infertility in Men – Possible Causes

In about half of the couples who trying to conceive, male infertility plays a role. Male Infertility may be due to low sperm production, low motility, or morphology. There may also be blockages that prevent the delivery of sperm. Illnesses, injuries, chronic health problems, lifestyle choices and other factors can play a role in causing male infertility.


Varicocele – The most common abnormality found on physical exam is a varicocele. This is a dilated vein around testicle and may impair the process of making sperm. The correction of this condition may involve a minor surgical procedure. The procedure will improve blood flow around the testicle and hopefully improve the quantity and quality of sperm.

Semen Analysis – Semen analysis is performed on an ejaculated sample collected after masturbation. It is best that this sample be collected after abstaining from sexual activity for two to five days. The laboratory will analyze for many different parameters, including fluid volume, sperm concentration, sperm motility and sperm morphology. Variations may occur from test to test and the analysis should be repeated at least twice. When there is an abnormal semen analysis, often an Urologist is consulted.
