Sperm Problem

A number of infertility cases have a sperm defect as the main cause or a contributing cause. Normal sperm have an oval head with a long tail. Abnormal sperm have head or tail defects — such as a large or misshapen head or a crooked or double tail. These defects may affect the ability of the sperm to reach and penetrate an egg.

The picture above illustrates different kinds of abnormal sperm being observed under microscope.

Obstructive Azoospermia

Obstructive Azoospermia means not having any measurable level of sperm in man’s semen. This problem is found in many of azoospermia cases. Obstruction may result from defects in any of the passage ways involved in the sperm delivery system. The obstruction may be either congenital (you were born with it) or acquired (you were not born with it). Surgical techniques such as MESA/ PESA/ TESA/ TESE for sperm aspiration or extraction are required to assist in the fertilitsation.
