Single-cell transcriptome analysis of the novel coronavirus (SARS-CoV-2) associated gene ACE2 expression in normal and non-obstructive azoospermia (NOA) human male testes

Science China Life Sciences, 2020
Being infected by SARS-CoV-2 may cause damage to multiple organs in patients, such as the lung, liver and heart. Angiotensin-converting enzyme 2 (ACE2), reported as a SARS-CoV-2 receptor, is also expressed in human male testes.

Transient Azoospermia Induced by Valganciclovir Treatment for Cytomegalovirus Infection in a Reproductive Male After Kidney Transplant: A Case Report

IJU Case Reports, Volume 8, Issue 4, Page 431-434, July 2025.
ABSTRACT Introduction Spermatogenic dysfunction is a side effect of valganciclovir, which is commonly used to treat cytomegalovirus infections. Here, we report the case of a reproductive man who underwent kidney transplantation and was diagnosed with azoospermia after valganciclovir treatment for cytomegalovirus infection.

How exome sequencing improves the diagnostics and management of men with non‐syndromic infertility

Andrology, Volume 13, Issue 5, Page 1011-1024, July 2025.
Abstract Male infertility affects approximately 17% of all men and represents a complex disorder in which not only semen parameters such as sperm motility, morphology, and number of sperm are highly variable, but also testicular phenotypes range from normal spermatogenesis to complete absence of germ cells.

Phenotypic continuum and poor intracytoplasmic sperm injection intracytoplasmic sperm injection prognosis in patients harboring HENMT1 variants

Andrology, Volume 13, Issue 5, Page 1137-1148, July 2025.
Abstract Background Small RNAs interacting with PIWI (piRNAs) play a crucial role in regulating transposable elements and translation during spermatogenesis and are essential in male germ cell development. Disruptions in the piRNA pathway typically lead to severe spermatogenic defects and thus male infertility. The HENMT1 gene is a key player in piRNAs
