About this trial
Hypotheses:
We hypothesize that serum progesterone levels on the day of embryo transfer in HRT-FET cycles are positively associated with clinical pregnancy rates.
Aims:
To evaluate the relationship between serum progesterone levels on embryo transfer day and clinical pregnancy outcomes in frozen-thawed embryo transfer cycles using hormone replacement therapy (HRT).
Primary outcome:
To compare the incidence of clinical pregnancy outcome in those infertility patients undergoing frozen embryo transfer with caterized Progesterone level on the day of embryo transfer
Secondary outcomes:
Biochemical pregnancy rate. Implantation rate. Early pregnancy loss rate. Ectopic pregnancy rate.
