PESA/TESA/TESE

PESA and TESA fall under obstruction category

TESA (Testicular Sperm Aspiration)

This technique is done by using a needle attached to a syringe. The process is injection of needle through the skin of the scrotum and taking out of the fluid in the testicle.

PESA (Percutaneous Epididymal Sperm Aspiration)

The process involves the needle and syringe like in TESA technique, only difference is the needle is directly positioned into the epididymis.

Surgical sperm retrieval when there is no obstruction

Some men can produce semen, but no sperm, despite no obstacles in tubes in their testicles. These people face issues in the production of sperm and there is lesser amount of sperms. So, these people have to undergo surgical retrieval process with no obstruction.

TESE, and Micro-Tese comes under no obstruction category

TESE (Testicular Sperm Extraction)

In this process the scrotum needs to be opened for taking a large amount of testicular tissues from several parts of the testicle. Then sperm is retrieved with the help of a microscope to discover a healthy and single sperm.

Success rates after sperm surgical retrieval

The infertility techniques are in their early stage and the details are collected. This is too early to comment about the treatments. In the released analysis of the process MESA comes first, followed by ICSI, and above explained treatments. ICSI reported pregnancy and fertilization rates of 45 to 52%.

Conclusion

These alternative methods of retrieving of sperm let men to use their own sperm under the IVF process. This process cost less; also eliminate the requirement of sperm donor and the cost for the same. There are several fertility clinics in India that offers these facilities at low cost to the infertility couples with high success rates. The retrieved sperm are used in the in vitro fertilization (IVF), egg donation treatments, or gestational surgery with Intracytoplasmic Sperm Injection (ICSI).
