Etiologies of sperm oxidative stress

open access: goldInternational Journal of Reproductive BioMedicine, 2016
Sperm is particularly susceptible to reactive oxygen species (ROS) during critical phases of spermiogenesis. However, the level of seminal ROS is restricted by seminal antioxidants which have beneficial effects on sperm parameters and developmental ...

Validation of sORP, a Measure of Oxidative Stress, in Australian Population

open access: yesFertility & Reproduction, 2022
Background: Excessive reactive oxygen species are normally eliminated by seminal plasma free radical antioxidant scavengers and enzymes. Assessing the oxidation reduction potential of seminal fluid (mV/million sperm/mL) enables the detection of an ...

Impairment of spermatogenesis and sperm motility by the high-fat diet-induced dysbiosis of gut microbes

open access: yesGut, 2020
Objective High-fat diet (HFD)-induced metabolic disorders can lead to impaired sperm production. We aim to investigate if HFD-induced gut microbiota dysbiosis can functionally influence spermatogenesis and sperm motility.
