Thin Endometrium, Female Infertility
Intrauterine G-CSF Infusion for Thin Endometrium
Thin endometrium is a condition in which the lining of the uterus is too thin during preparation for embryo transfer. This may reduce the chance of pregnancy and live birth in patients undergoing frozen-thawed embryo transfer.
