Oxidative stress plays a major role in the life and death of mammalian spermatozoa. These
gametes are professional generators of reactive oxygen species (ROS), which appear to …

This article addresses the importance of oxidative processes in both the generation of
functional gametes and the aetiology of defective sperm function. Functionally, sperm …

Reactive oxygen species (ROS) generated at low levels during mitochondrial respiration
have key roles in several signaling pathways. Oxidative stress (OS) arises when the …

The effects of diabetes mellitus include long-term damages, dysfunctions, and failures of
various organs. An important complication of diabetes is the disturbance in the male …

Oocytes and preimplantation embryos require careful regulation of the redox environment
for optimal development both in vivo and in vitro. Reactive oxygen species (ROS) are …

Varicocele is recognized as the leading cause of male infertility because it can impair
spermatogenesis through several distinct pathophysiological mechanisms. Current …

In brief Many aspects of the reproductive process are impacted by oxidative stress. This
article summarizes the chemical nature of reactive oxygen species and their role in both the …

Free radicals are molecules with one or more unpaired electron (s) commonly found in
seminal plasma. Physiologically, free radicals control sperm maturation, capacitation and …

Assessment of male fertility is based on the evaluation of sperm. Semen evaluation
measures various sperm quality parameters as fertility indicators. However, semen …

OBJECTIVE: To determine the abnormal patterns of reactive oxygen species (ROS)
production in male factor infertility (MFI) patients and to define the ROS reference values in …
