Molecular Biology of Spermatogenesis: Novel Targets of Apparently Idiopathic Male Infertility
International Journal of Molecular Sciences, 2020 Male infertility affects half of infertile couples and, currently, a relevant percentage of cases of male infertility is considered as idiopathic. Although the male contribution to human fertilization has traditionally been restricted to sperm DNA ...

Asian Journal of Andrology, 2014 Excessive amounts of reactive oxygen species (ROS) cause a state of oxidative stress, which result in sperm membrane lipid peroxidation, DNA damage and apoptosis, leading to decreased sperm viability and motility. Elevated levels of ROS are a major cause

Contribution of Bacterial Infection to Male Infertility in Nigerians [PDF]
, 2009 There is disagreement as to the influence of certain microbial infection on male infertility and such agents are ignored. The incidence of these microbial agents in seminal fluid isolates is on the increase.

Role of Oxidative Stress in Male Infertility: An Updated Review
Journal of Human Reproductive Sciences, 2019 Current evidence links oxidative stress (OS) to male infertility, reduced sperm motility, sperm DNA damage and increased risk of recurrent abortions and genetic diseases.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Middle East Fertility Society Journal, 2018 Objective: The aim of this study was to compare intra-Cytoplasmic Sperm Injection (ICSI) outcomes (fertilization rate, embryo quality, pregnancy rate, and live birth rate) for couples with unexplained infertility and couples with male factor infertility,

Oxidative stress and male infertility
Reproductive Medicine and Biology, 2020 Between 30% and 80% of patients with male infertility produce excessive reactive oxygen species (ROS) in their ejaculate even though the cause of male infertility is unexplained in approximately half of cases.

FEBS Open Bio, EarlyView.This study optimizes a two‐step induction system to generate PGCLCs from chicken ESCs. The induced cells express germline markers and migrate to gonads in ovo, offering a novel approach for avian genetic resource conservation. Primordial germ cells (PGCs) are the progenitor cells of sperm and eggs.
