Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The study includes men who underwent their first micro-TESE at a high-volume fertility center over a 10-year period. All procedures followed a standardized surgical protocol and were performed by a single experienced surgeon, ensuring uniformity in technique.
Clinical data routinely collected before surgery, such as hormone levels, semen parameters, testicular volume, and relevant medical history, were analyzed and compared between men who required only the mini-incision and those who proceeded to an extended dissection. By examining these differences, the study aims to determine whether certain patient characteristics can predict the success with the less-invasive approach.
The findings may help guide pre-surgical counseling and support more tailored surgical planning for men with severe male factor infertility
