Percutaneous Epididymal Sperm Aspiration (PESA)
A technique that, like TESA, may be repeated multiple times at a minimal cost and without a surgical cut. PESA is used to treat obstructive azoospermia in particular. It does not necessitate the use of a high-powered microscope. PESA can be performed under either local or general anaesthesia. The doctor carefully removes fluid from the epididymis using a needle linked to a syringe. When sperm do not come out during the PESA process, a surgical operation is required.
This procedure is performed in case of obstruction of the vas deferens. Most often, this involves collecting spermatozoa which are then analyzed in one of our sperm analysis testing centres. Only the healthiest of them are used for IVF with micro-injection.
