Association of raised serum progesterone and gene polymorphisms with risk of failure pregnancy and miscarriage

•In a controlled prospective study patients undergoing COS under controlled ovarian hyper stimulation were evaluated.•The ovulation trigger yielded >6 oocytes retrieval in majority of the patients.•The mean stromal day were found to be statistically significant whereas the mean day of glands were insignificant.•None of polymorphisms deviated Hardy Weinberg equilibrium, suggesting that distribution is representing actual population.•The level of cytokines is guarded by various parameters, which are essential for a successful pregnancy•It is very complicated to predict the effect on endometrium and corresponding pregnancy rates due to increased progesterone. Balanced cytokine required for a healthy pregnancy to avoid miscarriage. There is yet no accord on the effect of raised progesterone on the endometrium, recurrent miscarriage and association with cytokines. The present study see the effect of raised serum progesterone level on ovulation, miscarriage, and association of selected Cytokines polymorphisms with recurrent miscarriage. In a controlled prospective study patients undergoing COS under controlled ovarian hyper stimulation were evaluated. On the day of trigger progesterone levels were measured and serum hormonal estimation assay was done on the day of ovulation trigger by automated immunoassay. Genotyping analysis using allelic discrimination method was conducted which detects SNPs base pair differences by comparing allele-specific fluorescence signal. There was no significant different between cases and controls in age, smoking habit and alcohol consumption habit. The ovulation trigger yielded >6 oocytes retrieval in majority of the patients. The mean stromal day were found to be statistically significant whereas the mean day of glands were insignificant. There is no significant difference observed between two groups for three studied polymorphisms. None of the polymorphisms deviated significantly from the Hardy Weinberg equilibrium, suggesting that the distribution in our subjects was representative of the actual population. The level of cytokines is guarded by various parameters, which are essential for a successful pregnancy. It is very complicated to predict the effect on endometrium and corresponding pregnancy rates due to increased progesterone.
