PESA/TESA treatment at IFC
Percutaneous epididymal sperm aspiration (PESA) is a male infertility treatment to collect sperms of males with fertility issues. In this case, a thin, delicate needle is inserted into the scrotum to gather sperms from the epididymis where the sperms are stored. It is also considered as a part of Intra Cytoplasmic Sperm Injection (ICSI) to obtain sperms.
PESA is performed in males with zero sperm counts due to production in sperms or blockage in the male’s reproductive tract. A male with azoospermia, a condition of absence of sperms, at our clinic is closely evaluated by our urologist, who has specialized training to treat male infertility cases. Blood tests, examinations or if required, testicular biopsy is done to determine the most viable treatment option to achieve maximum sperm.
In ICSI, PESA treatment at our clinic in New Delhi is usually done in the morning of egg retrieval while TESA is done a day before egg retrieval. A small needle is used and the patient is kept under the influence of local anesthesia, whereas in TESA, sperms are aspirated using testicular biopsy.
PESA / TESA is primarily done in cases where the male has absolutely no sperms or azoospermia. Both PESA and TESA are performed under the influence of general anesthesia. In PESA, sperms are obtained from the epididymis and in TESA, sperms are taken from testicles and they do not take more than 15-20 minutes to complete.
