If sperm are seen then additional tubule is pulled out from the same site. The determination of hormone levels, including total and free testosterone, FSH, LH, and estradiol, is recommended six months after open testicular retrievals. If no sperm are found, or if the tubule appears fibrous, then another area is punctured and another tubule is pulled out and examined. This could be because:. Find articles by Sandro C Esteves.
Surgical sperm extraction

This is grasped with non-serrated microsurgical forceps and more tissue is pulled out of the testis. Conversely, the absence of sperm in a biopsy specimen does not absolutely exclude the chances of finding sperm elsewhere within the testis due to the heterogenic distribution of spermatogenesis in NOA men 5,8,
An update on sperm retrieval techniques for azoospermic males
The needle is usually inserted into the anteromedial or anterolateral portion of the superior testicular pole at an oblique angle toward the medium and lower poles. How to cite this article: However, this implies that it would be possible to cryopreserve the scanty sperm obtained in these men and retrieve them in adequate numbers after thawing, with no reduction in the fertilization and pregnancy rate as compared to fresh sperm. It is still a matter of debate whether percutaneous retrievals are more cost-effective than MESA. Repeated or multiple testicular biopsies may increase the risk of androgen deficiency [ 28 , 32 ]. Pregnancy after fertilisation with human testicular spermatozoa. The goal of percutaneous epididymal sperm aspiration PESA is to obtain the epididymal fluid, which should contain sperm.
The operation required a hospital stay and lengthy recuperation. In conclusion, testicular damage can be found independently of the kind of intervention used. Non-obstructive azoospermia NOA , on the other hand, is a consequence of spermatogenic failure and is the cause of most cases of azoospermia 8. The extraction of the testicular parenchyma for sperm search and isolation was first described in Van Steirteghem, and P. If you have any side effects at all, you should contact your clinic straight away.
