Before undergoing TESA, couples will meet with a fertility specialist to assess whether the procedure is the right approach for their specific fertility challenges. The male partner will undergo a thorough medical evaluation, including a semen analysis, hormonal tests, and sometimes a genetic screening, to understand the root cause of the fertility issue.

TESA is typically performed under local anesthesia and is a relatively quick procedure. During the procedure, A small needle is inserted into the testicle or epididymis. A tissue sample is aspirated using gentle suction. The tissue is then processed in the lab to extract viable sperm. TESA is usually completed in less than 30 minutes and is considered minimally invasive, with most patients recovering quickly.

After the sperm-containing tissue is collected, it is sent to a laboratory where embryologists isolate and prepare the sperm for fertilization. The retrieved sperm are assessed for quality, and the best sperm are selected for use in fertilizing the female partner’s eggs, typically through ICSI. If enough sperm are obtained, they may also be frozen for future fertility treatments.

Once the sperm have been selected, they are injected directly into the retrieved eggs through the ICSI process. Fertilization is carefully monitored over the following days, with embryologists observing the development of the embryos. Once the embryos reach the appropriate stage of development, they are prepared for transfer to the woman’s uterus.

The highest-quality embryos are selected for transfer into the female partner’s uterus. The embryo transfer is a simple, minimally invasive procedure that typically doesn’t require sedation. Following the transfer, the patient is monitored to ensure optimal conditions for embryo implantation.

After the embryo transfer, the patient is monitored to support successful implantation. A pregnancy test is conducted approximately 10 to 12 days after the procedure to determine if the treatment was successful. If the test is positive, regular monitoring and check-ups will follow.
