Summary

This study tests whether infusing platelet-rich plasma (PRP) into the uterus can thicken the uterine lining and improve pregnancy success in women with infertility who have had failed IVF cycles due to a thin lining. About 62 women will receive either PRP or a placebo during a frozen embryo transfer cycle. The main goal is to see if PRP increases lining thickness and leads to more sustained pregnancies.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients who have previously undergone at least 2 unsuccessful frozen embryo transfer cycles, defined as failure to achieve a sustained clinical pregnancy (visualization of intrauterine gestational sac on ultrasound or a cancelled embryo transfer cycle due to inadequate endometrial thickness * Patients with a diagnosis of thin endometrial lining (less than or equal to 6 mm maximum thickness) during prior unsuccessful or canceled embryo transfer cycles. Exclusion Criteria: * Fewer than 2 prior unsuccessful or canceled frozen embryo transfer cycles. * Most recent unsuccessful embryo transfer prior to January 1, 2017. * Mullerian anomalies, excluding arcuate uterus * Concurrent submucosal fibroids, unrepaired uterine defects or present indication for uterine surgery * Communicating hydrosalpinx without plans for surgical correction prior to study enrollment. * Failure of patient to agree to enrollment in study with written consent. * Concurrent pregnancy * Anticoagulation use for which plasma infusion is contraindicated * History of thrombosis * Thrombophilia either inherited or acquired * Concomitant use of adjunctive therapies for proliferation. These must be discontinued upon enrollment. * Embryo planned to be used for transfer generated from surgically obtained sperm due to a diagnosis of non-obstructive azoospermia * Recurrent/persistent endometrial fluid in prior cycles
