Teratozoospermia

Overview

Teratozoospermia is a condition where there is an increase in abnormal sperms in a man’s semen. When the concentration of sperm with abnormal morphology exceeds 96% of the semen sample, Teratozoospermia is diagnosed. As the abnormal sperms become unable to fertilize the egg, the condition directly affects fertility.

Diagnosis

Teratozoospermia is diagnosed through a semen analysis test. According to the WHO, there must be at least 4% sperms with a normal morphology for the sample to be considered normal. Kruger parameters dictate that is 4 to 15 % of the sperms are normal, the sample has moderate Teratozoospermia. If the sample has less than 4% normal sperms, it indicates severe Teratozoospermia.
