Comparative study of intrauterine infusion of autologous platelet rich plasma in unresponsive thin endometrium in frozen ET cycle

Abstract

Aims: Study of intrauterine infusion of autologous platelet rich plasma in unresponsive thin endometrium in frozen ET cycle .Thin endometrium still remains a big challenge for clinicians, creating so much burden in the form of cycle cancellation, unplanned freezing of embryo and even need for surrogacy. Intrauterine infusion of platelet-rich plasma (PRP) is newer modality of treatment in thin endometrium, in various studies showing promising results. Material and methods: Our study was prospective randomised controlled trial done from 1 August 2018 to 31 May 2019 at a tertiary infertility centre, New Delhi, India. 30 patients undergoing frozen embryo transfer with history of thin endometriun (less than 7 mm) with normal hysteroscopic examination were enrolled. Patients with platelet count less than 1.50000/dl, uncorrected asherman syndrome, submucosal polyp, fibroid or congenital uterine anomaly and with history of systemic diseases were excluded from study. From day 2 of menses tab estradiol valerate was started in dose of 6–8 mg/day. It was increased up to 12 mg/day gradually after reviewing endometrial thickness serially. Patients with thin endometrium on day 10/11 received PRP on day 11 and repeat dose after 48 hours if endometrial thickness was less than 7 mm. Frozen embryo transfer was done in patients who achieved endometrial thickness 7 mm or more. Results: The mean pre-treatment endometrial thickness was 5.42 mm, which significantly increased to 6.64 mm, post treatment (P
