Summary

The goal of this retrospective observational study is to learn whether certain clinical characteristics can help predict which infertile men may successfully have sperm retrieved using a less-invasive "mini-incision" version of micro-TESE. The study focuses on men with very low or absent sperm counts (non-obstructive azoospermia, cryptozoospermia, or severe OAT).

The main questions it aims to answer are:

Can sperm be successfully found using only a small, limited-dissection micro-TESE in some men?

Which clinical factors (such as hormone levels or medical history) help identify men who may benefit from this less-invasive approach?

Researchers will compare men who had successful sperm retrieval with the mini-incision alone to men who required a more extensive micro-TESE to see if certain characteristics predict which approach is likely to work.
