AbstractAim: The aim of the present study was to evaluate the effect of intrauterine instillation of autologous platelet richplasma and G-CSF on endometrial thickness and pregnancy rate in frozen embryo transfer for women with thinendometrium.Methods: The present retrospective cohort study was conducted in the department of reproductive medicine,IGIMS, Patna, Bihar, India. All the patients of age group 22 – 40 years coming to OPD for ART during the periodof 9 months from March 2022 to November 2022 was selected after randomization into two groups for this studyafter fulfilling the inclusion & exclusion criteria. Sample sizes of 100 subjects were included in the final analysis.Results: The mean age, BMI, S AMH in both the groups were not statistically significant. The most frequentfactor for thin endometrium is AKT-or patients on anti-kochs treatment followed by uterine anomalies. Thedistribution of various other factors have been discussed here like RIF, RPL, endometriosis and ashermannssyndrome which are commonly associated with thin endometrium. Both the groups have similar distribution offactors. The mean of the endometrial thickness before and after are compared in both the groups with injectionGCSF showing higher increase in endometrial thickness than intrauterine PRP after 48 hours of administration. Itwas found that for chemical and clinical pregnancy rates, the p values were 0.77 and 0.37 respectively and hencestatistically not significant.Conclusion: Through the analysis done in this study it becomes evidently clear that injection GCSF is superiorin its action as compared to intrauterine Platelet Rich Plasma in increasing the endometrial thickness in patientsdiagnosed as thin endometrium for infertility.
