Micro-surgical Sperm Aspiration

PESA-percutaneous epidydimal sperm aspiration, TESE-testicular sperm extraction, mese-microsurgical epidydimal sperm extraction. These are surgical procedures carried out by the andrologist on the male partner, if he is azoospermic, to aspirate or extract sperm to carry out ICSI to achieve a pregnancy. Azoospermia is a condition where no sperms are present in the fluid a man ejaculates. A man might have azoospermia because of a blockage in the connecting passages from the testicles-called obstructive azoospermia or very few sperms or no sperm produced in the testicles called non-obstructive azoospermia.
