Abstract
Background: The increasing prevalence of infertility cases is becoming a major public health problem in developing countries due to changes in diet and lifestyle. Objectives: Black Carrot Extract BCE (Daucuscarota) plays an important role as fertility agent due to its antioxidant and anti-proliferative properties. Therefore, the aim of the present study was to identify the effects of different concentrations of BCE on the outcome of in vitro human sperm activation of infertile patients. Methods: Thirty two semen samples were prepared which served as a control, using direct swim-up technique. Modified Earl's medium (MEM) was used only in group 2 (G2) and two concentrations of BCE (10µg/1ml and 20µg/1ml) were added to culture media MEM of groups 3 (G3) and 4 (G4) for in vitro sperm activation (ISA). Results: A highly significant (P<0.001) correlation was noticed between G4 with G2 and G3 in progressive motility when activation by adding 20µg/1ml of BCE to culture media as compared to G3 (which adding 10µg/1ml of BCE to culture media) and G2 (activation with culture media only). Moreover, swim-up activation technique with culture media and by both adding (10µg/1ml and 20µg/1ml of BCE respectively) to culture media enhancement in the (sperm motility, progressive sperm activity and sperm morphology). Conclusion: The high concentration of BCE is effective in the enhancement of progressive sperm activity during in vitro human sperm activation.
