Knowledge BasePESA, TESA and TESE
In PESA (percutaneous epidydimal sperm aspiration), a small needle is placed into the epidydimis, which is a reservoir of sperm that sits atop each testicle, using local anesthesia to obtain sperm in certain cases of male infertility Men who have no or very few sperm in their ejaculate due to a blockage or complete absence of the vas deferens, which carries the sperm from the testes to the penis, will require Testicular Sperm Aspiration (TESA). During TESA, sperm is obtained by means of a biopsy of the testicle. The sperm obtained from these procedures is then injected directly into the eggs.
