A Novel Mutation of DAX-1 Associated with Secretory Azoospermia. [PDF]

PLoS ONE, 2015
Secretory azoospermia is a severe form of male infertility caused by unknown factors. DAX-1 is predominantly expressed in mammalian reproductive tissues and plays an important role in spermatogenesis because Dax-1 knockout male mice show spermatogenesis ...

TXNDC2 joint molecular marker is associated with testis pathology and is an accurate predictor of sperm retrieval

Scientific Reports, 2021
The association of PRM1/2 with male azoospermia is well-documented, but the relationship between TXNDC2 deficiency and the azoospermia phenotype, sperm retrieval, and pathology has not been elucidated.

Sperm retrieval rates and clinical outcomes for patients with different causes of azoospermia who undergo microdissection testicular sperm extraction-intracytoplasmic sperm injection

Asian Journal of Andrology, 2020
The aim of our study was to compare the sperm retrieval rates (SRRs) and clinical outcomes of patients with different causes of azoospermia who underwent microdissection testicular sperm extraction-intracytoplasmic sperm injection (micro-TESE-ICSI).

A case of azoospermia in a non-destructive testing worker exposed to radiation

Annals of Occupational and Environmental Medicine, 2017
Background Interest in radiation-related health problems has been growing with the increase in the number of workers in radiation-related jobs. Although an occupational level of radiation exposure would not likely cause azoospermia, several studies have ...

Differentiating between obstructive and non‐obstructive azoospermia: A machine learning‐based approach

BJUI Compass
Background Infertility is a major global concern, with azoospermia, being the most severe form of male infertility. Distinguishing between obstructive azoospermia (OA) and non‐obstructive azoospermia (NOA) is crucial due to their differing treatment ...
