Analysis of genes implicated in non-obstructive azoospermia

Non-obstructive azoospermia (NOA) is the most common cause of male infertility, accounting for approximately 60 % of azoospermia cases. In recent years, gene mutations have emerged as the primary factor under investigation for the etiology of NOA. Therefore, finding the cause and pathogenesis of NOA at the genetic level has become one of the current research hotspots. Genetic analysis of NOA patients revealed that gene mutations primarily concentrate in protein-coding regions and non-coding RNAs, predominantly occurring in cases of non-obstructive azoospermia. Hence, understanding the relationship between these gene mutations and NOA can not only provide new ideas for treatment, but also provide a theoretical basis for revealing the pathogenesis of NOA. This article comprehensively reviews recent advancements in identifying genes that are intricately associated with azoospermia. These results will provide meaningful guidance for the future development of NOA-targeted therapeutic drugs.
