Autologous Platelet-rich Plasma for Clomiphene Citrate-induced Thin Endometrium

This is a pilot prospective self-controlled clinical trial. Women with Clomiphene Citrate failure with documented thin endometrium less than 7 millimeters for at least 3 stimulation cycles will be chosen (N = 30). Patients will experience 2 ovarian stimulation cycles with Clomiphene citrate (CC) in a dose of 100 mg/ day for 5 days starting from cycle day 3. A control cycle (CC only cycle) woman will continue on Clomiphene Citrate alone plus cervical irrigation of cervix with 1 ml of 0.9% normal saline at cycle day 8 and 10 to confirm patient-blinded process. The study group, the same will be done in addition to the intrauterine infusion of with Autologous platelet-rich plasma (PRP) in 8th and 10th days of the cycle. In both groups, the endometrial thickness and Power Doppler evaluation of their endometrial and sub-endometrial blood flow will be measured on the day of HCG administration.
