TESA (testicular sperm aspiration)

Testicular sperm aspiration (TESA) is a minimally invasive procedure used to retrieve sperm from the testicles of men who have low sperm counts or no sperm in their ejaculate. This procedure is often used in conjunction with in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) to help couples conceive.

​

During TESA, a small needle is inserted into the testicle under local anesthesia, and a small sample of tissue is aspirated, or drawn out, from the testis. This tissue is then examined under a microscope to identify and isolate viable sperm.

​

TESA 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, have undergone a previous vasectomy, or have low sperm counts due to other medical conditions.

​

After the sperm is retrieved through TESA, 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, TESA is a safe and effective option for men who have low sperm counts or no sperm in their ejaculate and wish to conceive. 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.
