Sperm quality improvement after date seed oil in vitro supplementation in spontaneous and induced oxidative stress.

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. Sixteen patients (mean age: 35 years; range: 25-45 years) referred to the Histology-Embryology Laboratory of the Medicine Faculty of Sfax for semen analysis after 12-24 months of sexual intercourse without conception were selected.
