PESA( percutaneous epididymis sperm aspiration)
Percutaneous epididymal sperm aspiration (PESA) is a minimally invasive procedure used to retrieve sperm from the epididymis, a small tube located behind the testicles that carries and stores sperm. This procedure is often used in conjunction with in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) to help couples conceive.
During PESA, a small needle is inserted through the scrotum and into the epididymis, under local anesthesia, to retrieve a sample of fluid that contains sperm. This sample is then examined under a microscope to identify and isolate viable sperm.
PESA is a safe and effective procedure that is typically performed on an outpatient basis. It is often recommended for men who have a blockage in their reproductive tract or have undergone a previous vasectomy.
After the sperm is retrieved through PESA, it is typically used in conjunction with assisted reproductive techniques, such as IVF or ICSI, to fertilize an egg and facilitate conception. The success rates of these techniques vary depending on several factors, including the age and fertility of the female partner, the quality of the sperm, and the skill of the medical team performing the procedure.
Overall, PESA is a safe and effective option for men who have difficulty conceiving due to a blockage in their reproductive tract or a previous vasectomy. It is important to discuss the risks and benefits of this procedure with a qualified healthcare provider to determine if it is the right choice for an individual's specific situation.
