TESE (Testicular Sperm Extraction) & PESA (Percutaneous Epididymal Sperm Aspiration)
Couples facing problems in conceiving may be as a result of male infertility. Some male partners are azoospermic as they have no sperms in their semen.
In most of these men fortunately sperm may be found in the testicle (sperms are producing site) or the epididymis (sperms are storing site). Using an ICSI technique these sperms can fertilize an egg when injected directly.
Azoospermic men were considered infertile since this method was developed. Now with the assistance of TESE and ICSI many of such couples are able to conceive today.
With the help of local or general anesthesia extraction procedure is performed. Testicular tissue is scanned under microscope and sperm is extracted. Typically, number of sperm is small in such tissue sample, or several of them lack the ability to move forward. Chances of conception are appealing as in most cases fertilization occur by way of one sperm needed to fertilize one egg.
