Treatment of unexplained thin endometrium with autologous platelet-rich plasma in a frozen embryo transfer cycle
Inadequate endometrial proliferation is a known cause of implantation failure in assisted reproductive technology cycles. It is generally agreed that >9 mm endometrial thickness is associated with higher implantation. Several strategies have been explored to enhance endometrial proliferation. However, the results are either poor, inconsistent or subject to safety concerns. A 34-year old woman presented with unexplained thin endometrium in successive frozen embryo transfer (FET) cycles. Autologous platelet-rich plasma (PRP) was infused in the uterine cavity on day 10 of second FET cycle enhancing endometrial thickness, which post-PRP infusion measured 10.9 mm. Blastocyst-stage embryos were transferred resulting in a successful pregnancy. Autologous intrauterine infusion of PRP positively impacts endometrial proliferation and implantation which is safe, low resource and minimally invasive.
