Summary

There are three main cycle regimens used for endometrial preparation for frozen embryo transfer（FET）: natural cycles (NC) with/without ovulation triggering, hormone replacement therapy cycles (HRT) in which the endometrium is artificially prepared by estrogen and progesterone hormones with/without a gonadotrophin releasing hormone agonist (GnRH-a) down regulation, and ovulation induced cycles (OI) in which follicular development is supported with increasing doses of gonadotrophin hormones and ovulation is induced. At present, there is still no sufficient evidence that which kind of FET cycle regimen to plan more advantage. The purpose of this study was to compare the pregnancy outcome of NC-FET to that of HRT-FET in women with regular cycles.

Conditions

Interventions

OTHER

natural cycles

the ovulation is monitored spontaneously or induced by HCG when the dominant follicle is larger than 18mm without LH surge. Transfer of thawed embryos will be performed 4 days after LH surge/HCG administration or 3 days after ovulation is observed.

DRUG

estradiol and progesterone

oral estradiol, 2 mg, once daily, is introduced on cycle day 3 with an increasing doses protocol. If the endometrial thickness is greater than 7mm, progesterone 40-60 mg in oil will be administered via intramuscular injection. Transfer of thawed embryos will be performed 3 days later.
