OBJECTIVE Overproduction of reactive oxygen species results in oxidative stress, a deleterious process that damages cell structure as well as lipids, proteins, and DNA. Oxidative stress plays a major role in various human diseases, such as oligoasthenozoospermia syndrome. MATERIALS AND METHODS We evaluated the effectiveness of antioxidant co-supplementation therapy using vitamin C, vitamin E,...

We present nine cases of spermatid intracytoplasmic injection for the treatment of non-obstructive azoospermia. In eight cases, no elongated spermatids or spermatozoa were found in previous spermiograms or testicular biopsies. In these patients, treatment was performed using ejaculated (n = 6) and testicular (n = 2) retrieved round spermatids (Sa type). In cases where ejaculated round spermatid...

In vitro supplementation with date seed oil (DSO) can protect spermatozoa against hydrogen peroxide (H2O2)-mediated damage and can improve sperm function, possibly owing to antioxidant properties. We tested the antioxidant effects of DSO on human sperm motility, sperm viability, reacted acrosome and lipid peroxidation assessed in vitro after H2O2-mediated oxidative damage in spermatozoa. Sixtee...

Varicocelectomy is the most commonly performed operation for the treatment of male infertility. Varicocele is found in approximately 15% of general male population and in 40% of men with infertility. The treatment of varicocele is not necessary unless the varicocele causes pathological spermiogram, difficulties and intense testicular volume at work and walking, also in children with varicocele ...
