Effect of platelet-rich plasma in regeneration of thin endometrium and its implications in in vitro fertilization cycles: A novel approach

Abstract

The thin endometrium is an important cause of failure of cycle cancellations in in vitro fertilization (IVF). Several modalities like estrogen, lowdose aspirin, heparin, vaginal sildenafil, pentoxifylline, and granulocyte-colony stimulating factor (G-CSF) intrauterine perfusion have been tried and studied in patients with a thin endometrium. We discuss platelet-rich plasma (PRP) administration by intrauterine infusion as a novel approach in these patients. We reviewed and analyzed all important and relevant articles including case series, pilot studies, and case reports published from January 2000 to December 2020. Studies pertaining to other uses of PRP were not included. We found that intrauterine infusion of PRP can significantly increase the endometrial thickness and improve the pregnancy rates in infertile patients with thin endometrium <6 mm.
