Vitamin E effect on controlled ovarian stimulation of unexplained infertile women.
OBJECTIVE
To determine Vit E effect on the treatment outcomes of women with unexplained infertility undergoing controlled ovarian stimulation and intrauterine insemination (IUI).


METHODS
The study group (Group A, n053) underwent controlled ovarian stimulation with clomiphene citrate with Vit E administration, 400 IU/day p.o. while the control group(Group B, n050) underwent ovulation induction without VitE. Treatment outcomes were compared between the groups.


RESULTS
There were no significant differences between the two groups with respect to the demographic outcomes. The difference in endometrial thickness on the day of hCG administration was significant between the two groups (p00.001).The effect of receiving Vit E on the implantation and the on going pregnancy rates were assesed Odds Ratio (OR) and corresponding 95% Confidence Intervals (CI). Receiving Vit E was not significantly associated with the implantation and the ongoing pregnancy rates; OR 0 1.22, 95% CI (0.44–3.4)and OR 0 1.43, 95% CI (0.49–4.1), respectively.


CONCLUSIONS
Vit E administration may improve the endometrial response in unexplained infertile women via the likely antioxidant and the anticoagulant effects. It may also modulate the antiestrogenic effect of clomiphene citrate and the problem of a thin endometrium in these cycles may beadjusted
