Abstract

Objective: To study the impact of Vitamin E (VE) levels of follicular fluid (FF) on oocyte competence, embryo development and pregnancy outcome in patients after intra cytoplasmic sperm injection (ICSI). Methods: It was a cross-sectional study conducted in Islamabad Clinic Serving Infertile Couples in which follicular fluid of 137 females booked for ICSI, was obtained during oocyte retrieval, centrifuged and stored for analysis. VE levels in FF were analyzed by enzyme linked immune sorbent assay. Receiver Operating Curve (ROC)was used to demarcate VE levels required for acquiring pregnancy. Generalized linear model using log binomial regression was applied to see the effect of VE on pregnancy, the effect of VE on oocyte and embryo parameters was assessed by linear regression; all p-values less than 0.05 were considered statistically significant. Results: ROC suggested 5.49 (unit) as the cutoff value of VE in the pregnancy group, with 72.9% area under the curve. Ninety-one females comprised Group I with VE > 5.49, whereas forty six females formed Group II with VE < 5.49. Follicular fluid VE levels were significantly high in 39 (28.5%) females who compromised pregnancy group. Chances of pregnancy increased to 4% with an increase in VE levels (p-value 0.01). VE gave significant positive relationship with all oocyte (retrieved, mature and fertilized) parameters, cleavage of embryo till its differentiation to blastocysts (p<0.01). Conclusion: Adequate amount of VE in follicular fluid enhances the possibility of maturation of oocytes which resulted in better reproductive outcome after ICSI.
