Percutaneous epididymal sperm aspiration (PESA) and testicular sperm aspiration (TESA) are procedures for overcoming extreme male infertility. Men having very low or zero sperm counts, and sperm that are largely dead or completely immotile, can have children by these methods. The sperms are obtained directly from the testis or the tiny ducts leading from the testis (epididymis) before they risk damage from oxidation or are exposed to antisperm antibodies in the epididymis or the vas deferens. For men having azoospermia (complete absence of sperm) caused by the general failure to develop, small fields of sperm production that can often be located using TESA. The sperm collected can be used for intracytoplasmic sperm injection (ICSI). How is PESA done? How is TESA done? This procedure can be used for instances where sperm production is a problem (non-obstructive azoospermia) or where there is an obstruction to sperm flow (obstructive azoospermia). Obstructive azoospermia can be due to congenital absence of the vas deferens or after a vasectomy operation. TESA for non-obstructive azoospermia (low sperm production or maturation arrest) takes around an hour. Here both testicles are usually operated on, and multiple biopsies are taken. It is normally done under general anesthesia. However, very often sperms can be successfully aspirated by fine needle aspiration under local anesthesia or without any cut or stitches. What should be the timing of PESA/TESA? MESA and TESE are often performed in advance of the IVF cycle and frozen to reduce stress on the couple since the sperm is "safe in the bank" and can be used at any time. This approach allows each partner to be supportive to the needs of the other at time of their procedure.The chosen sperm retrieval method is timed to coincide with the female egg retrieval and IVF/ICSI cycle. The percutaneous methods are preferably done fresh since sperm quantity and quality may not be sufficient to allow for freezing. Can my children (born using TESA) inherit my condition? Can the sperm retrieved by PESA/TESA be used for IUI? Letters to Dr. Richa Katiyar Dear Dr. Richa, I feel that all my husbands semen flows out after intercourse. He got his speerm checked and there are no, He is azoo. How can i conceive? I amm very trobled. please reply.Nazneen Dear Nazneen,
Dr. Richa Dear Ma'am, Greetings of the day!! Sorry to learn that you are having problem in getting pregnant. With azoospermia, we have two options, either IUI or IVF. DEAR MAM,
