Platelets rich plasma: Effective embryo implantation requires a proper embryonic development coincident with a receptive endometrium. In clinical practice, satisfactory endometrial growth is needed for successful implantation. The required minimum endometrial thickness for embryo transfer is seven millimeters after the follicular phase. Thin endometrium non-responsive to standard treatments is still a challenge in assisted reproductive technique, which usually results in cycle cancellation and unexpected embryo cryopreservation. Hence various strategies have been developed for treating thin endometrium, including extended use of exogenous estrogen, use of low-dose aspirin, vitamin E and vaginal sildenafil citrate, electroacupuncture and application of granulocyte colony stimulation factor (G-CSF). However, several women with thin endometrium remain non-responsive even after these remedies are used.
