A Study of Human Chorionic Gonadotrophin as Luteal Phase Support in Frozen Embryo Transfer
A randomised trial on the use of luteal phase support in frozen-thawed embryo transfer cycles. The hypothesis of the study is that the use of luteal phase support with human chorionic gonadotrophin would increase the pregnancy…
