Anti-Müllerian hormone predicts positive sperm retrieval in men with idiopathic non-obstructive azoospermia—findings from a multi-centric cross-sectional study

open access: yesHuman Reproduction, 2023
STUDY QUESTION Is it possible to identify a reliable marker of successful sperm retrieval (+SR) in men with idiopathic non-obstructive azoospermia (iNOA) undergoing microdissection testicular sperm extraction (mTESE)?

Prevalence of Y chromosome deletions in a Brazilian population of nonobstructive azoospermic and severely oligozoospermic men [PDF]

open access: yes, 2003
We determined the prevalence of Y chromosome deletions in a population of 60 Brazilian nonobstructive azoospermic and severely oligozoospermic men. PCR-based screening of microdeletions was performed on lymphocyte DNA for the presence of 14 sequence ...
