Sperm function is essential for fertilization and embryogenesis yet semen contain a
heterogeneous population of sperm. This study was designed to evaluate two different …

The objective of the study was to assess whether seminal plasma total antioxidant status
(TAS) can be used as a biochemical predictor of male fertility and its variation in different …

Mammalian fertilization involves a concerted interplay between the male and female
gametes that ultimately results in the creation of new life. However, despite the fundamental …

The accurate, selective measurement of reactive oxygen species (ROS) production by
human spermatozoa is still a work-in-progress. Traditionally, chemiluminescence …

Infertility affects an estimate of 50–80× 10 6 (= 7–15% of men at reproductive age) men
globally and annually. Among these men, a large number of patients (25–40%) suffer from …

Oxidative stress, sperm DNA damage, and apoptosis are associated with male infertility as a
cause and as a manifestation. Several clinical conditions and laboratory findings may be …

Aim: To examine the effects of ROS and OS on male fertility and to evaluate the use of
antioxidants as a means of treatment to improve fertilization rates in subfertile males …

The exact pathophysiology of varicocele and the subsequent alteration of spermatogenesis
has been the subject of much debate. Despite an enormous amount of literature on the …

Free radical (oxygen and nitrogen-derived)-induced sperm DNA damage may take place
during the process of spermatogenesis, during sperm transit through the epididymis, in the …

Despite advances in cryopreservation methodology, one of the main detrimental effects of
cryopreservation on human spermatozoa is a marked reduction in motility. The primary …
