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.
Plasminogen Activator Inhibitor-1 expression in serum and follicular fluid plays a crucial role in regulating fibrinolysis during the pregnancy period by blocking the action of other proteins called plasminogen activators. The aim is to assess the Plasminogen Activator Inhibitor-1 level in blood serum and follicular fluid as a predictive marker of pregnancy. This study included Sixty-nine infertile females undergone ovarian stimulation with antagonist protocol and received recombinant follicle-stimulating hormone, at the cycle day two. The serum and follicular fluid were collected from each female on the day of oocyte retrieval, for PAI estimation using the Elisa kit. The data were analyzed using version 23.0 SPSS and Microsoft Office 2010. The serum PAI-1 levels at the day of oocyte retrievals were significantly lower in positive pregnancy women in comparison with non-pregnant women (p < 0.05), Yet no significant follicular fluid PAI-1 levels were noted in comparison with non-pregnant women. There was a negative significant correlation (p > 0.05) between serum and follicular fluid PAI-1 levels on the day of oocyte retrieval according to oocyte ICSI outcome. The evaluation of serum PAI-1 levels can be used as a promising parameter for the prediction of pregnancy outcomes of ICSI patients. It is assumed that the pregnancy rate was affected by PAI-1 level during ICSI cycles. The concentration of PAI-1 in serum and follicular fluid at the retrieval day is not correlated with the oocyte's maturity.
