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

IJU Case Reports
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 ...

Epigenetics of nonobstructive azoospermia

Asian Journal of Andrology
Abstract Nonobstructive azoospermia (NOA) is a severe and heterogeneous form of male factor infertility caused by dysfunction of spermatogenesis. Although various factors are well defined in the disruption of spermatogenesis, not all aspects due to the heterogeneity of the disorder have been determined yet.

Elevated LncRNA LINC00966 Suppresses PDE2A to Impair Sperm Motility in Asthenozoospermia

FASEB BioAdvances, Volume 8, Issue 8, August 2026.
This study identifies LINC00966 as an upregulated lncRNA in asthenozoospermia associated with reduced sperm quality. Linc00966 suppresses Pde2a, disrupts cGMP signaling, and promotes oxidative stress, thereby impairing spermatogenic cell viability and migration.

Spontaneous miscarriage after intracytoplasmic sperm injection with frozen sperm of patients with testicular germ cell tumour

BJU International, Volume 138, Issue 2, Page 315-323, August 2026.
Objective To clarify the impact of chromosomal aberrations on the offspring of patients with testicular germ cell tumour (TGCT) by evaluating the outcomes of intracytoplasmic sperm injection (ICSI). Patients and Methods Under the ethical review of Yokohama City University, 12 patients with TGCT and 25 with non‐TGCT cancer who had cryopreserved sperm ...

Intact spermatogenesis in an azoospermic patient with AZFa (sY84 and sY86) microdeletion and a homozygous TG12-5T variant in CFTR

Basic and Clinical Andrology
Background Azoospermia, the most severe form of male infertility, is categorized into two types: non-obstructive azoospermia (NOA) and obstructive azoospermia (OA), which exhibit significant genetic heterogeneity.

Varicocele and nonobstructive azoospermia

Asian Journal of Andrology
Abstract Approximately 15% of men in the general population have varicoceles, and varicoceles are diagnosed in 40% of men presenting for fertility evaluations. One percent of men in the general population are azoospermic, and 15% of men presenting for fertility evaluations are diagnosed with azoospermia. This article aims to review the impact

Genetic Insights into Azoospermia and Severe Oligozoospermia: Discovering Seven SNPs through GWAS and In Silico Analysis

Current Issues in Molecular Biology
Azoospermia and severe oligozoospermia represent the most extreme forms of male infertility. Despite their prevalence, the genetic foundations of these conditions are not well understood, with only a limited number of genetic factors identified so far ...
