Testicular Sperm Aspiration or TESA is a minor procedure yet a great technological advancement in the field of male infertility. The procedure that takes about 5 to 10 minutes under sedation is a marvel for men suffering with Obstructive Azoospermia. The procedure is mainly used to find sperm and source them from where they are directly produced.
The sperm that is then found from the testes can be either directly used for an IVF-ICSI cycle or can be preserved for later use. It should, however, be noted that while TESA is a viable option for both, Obstructive Azoospermia, as well as Non-Obstructive Azoospermia. But the chances of success of TESA are higher in men with Obstructive Azoospermia.
The combined effect of TESA with artificial reproductive technology has proven to be a boon to a high percentage of couples who face trouble in natural conception.
Q. Is TESA painful?
With needle aspiration procedures, there is generally some minor pain and swelling in the area, which fades away in a rather short span of time.
Q. How successful is TESA?
Sperm extraction through TESA has a really high rate of success. The general figure stands at above 80%, with some research studies also reporting a 100% success rate for sperm extraction.
Q. Can azoospermia cure itself?
Azoospermia is the condition where there are no sperms in the ejaculate of a male. It is generally of 2 types. Obstructive and Non-Obstructive Azoospermia, none of which are curable on their own. However, there are simple and non-obstructive surgical procedures that can be performed to either cure the condition, or assist in conception through artificial methods.
