The success rate of PESA (Percutaneous Epididymal Sperm Aspiration) is high. Studies have shown that, when performed by experienced surgeons, it can yield a pregnancy rate of up to 50%. This procedure is recommended for couples who have been trying to conceive through in vitro fertilization (IVF) for at least two to three years without success. PESA is also the preferred method for men with azoospermia (no sperm in ejaculate), as it often yields better results than other methods like testicular sperm extraction (TESE). Additionally, the procedure has minimal risk of infection and complication.
PESA can be done under local or general anesthesia and typically takes 30 minutes to an hour. The success rate increases with experience, so it is best to choose a clinic that has experience in performing the procedure. Furthermore, couples should always consult with their fertility specialist before undergoing this procedure for best results.
