Imaging methods for seminal tract obstruction

Андрология и генитальная хирургия, 2022
Differential diagnosis between obstructive and non-obstructive azoospermia is an important task in clinical management of infertile patients. Chances of extracting sperm in obstructive azoospermia are high enough to inform the couple about favorable ...

Chronic Immune-Mediated Orchitis Is the Major Cause of Acquired Non-obstructive Azoospermia in Dogs

Frontiers in Veterinary Science, 2022
Azoospermia, the lack of spermatozoa in the ejaculate, is the most common finding in infertile but otherwise healthy male dogs and represents an increasing reproductive health issue in men, too.

ThePGAM4gene in non-obstructive azoospermia [PDF]

Systems Biology in Reproductive Medicine, 2013
Non-obstructive azoospermia (NOA) is considered to be a severe infertility factor due to impaired spermatogenesis with the consequent absence of spermatozoa in the ejaculate. However, the underlying etiology and mechanism(s) remain elusive. The aim of this study was to investigate the mutation and association of single nucleotide polymorphisms (SNPs ...
