Percutaneous Epididymal Sperm Aspiration (PESA)

Percutaneous Epididymal Sperm Aspiration (PESA) is a medical procedure used to retrieve sperm from the epididymis, a duct located behind the testicles. The procedure is used to treat infertility in men who have a blockage in the reproductive tract, making it difficult for sperm to reach the semen.

PESA is typically performed using a fine needle that is inserted into the epididymis through the scrotal skin. The needle is used to aspirate (remove) a small amount of fluid from the epididymis, which is then examined in the laboratory to identify and retrieve the sperm. The sperm is then used for assisted reproductive technology (ART) procedures, such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).

PESA is a relatively simple and quick procedure that is performed in the doctor’s office or clinic. The procedure is performed under local anesthesia and typically takes less than 30 minutes.

The success rate of PESA depends on several factors, including the cause of infertility, the quality of the sperm, and the woman’s age. In general, the success rate of PESA is lower than that of other sperm retrieval methods, such as testicular sperm extraction (TESE).

It is important to discuss the risks and benefits of PESA with a fertility specialist, as well as any potential side effects and the cost of treatment, before starting the process. With advances in technology and the ongoing research in the field, PESA remains an effective option for individuals and couples facing infertility issues.
