TESA
TESA
One of the most recent sperm retrieval methods is called TESA, or testicular sperm aspiration. Men with azoospermia, a condition in which there are no sperm in the ejaculate, are suggested to perform this treatment. Previously, the only treatments for azoospermia were donor insemination or reconstructive surgery (if there was obstruction). Since the development of intra-cytoplasmic sperm injection (ICSI), many azoospermic men have been able to become biological fathers by using sperm from their testicles or epididymis.
The TESA test is used on males who need to have their sperm extracted for IVF or ICSI.. It is done under local anesthesia in the operating room or office, and it is timed to coincide with the egg retrieval of their female spouse. The testicle is pricked with a needle, and tissue and sperm are aspirated.
To fertilise an egg, sperm cells may not necessarily need to mature and go via the epididymis. They require ICSI, a procedure in which one sperm is extracted from the semen and inserted directly into the egg, as the testicular sperm are immature.
Given that TESA is a somewhat difficult surgery, there may be some discomfort for a few days. Without the need for a hospital stay, it is done under local anesthesia or sedation in a daycare setting.
