Patients with regular cycles undergoing FET in reproductive medicine renter of Sun Yat-sen Memorial Hospital will be recruited, who should not be elder than 40 and had more than 3 frozen embryos.They will be randomized to receive the natural cycles.
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.
Other Name: spontaneous ovulation cycles
Patients with regular cycles undergoing FET in reproductive medicine renter of Sun Yat-sen Memorial Hospitalwill be recruited , who should not be elder than 40 and had more than 3 frozen embryos will be randomized to receive the estradiol and progesterone replacement therapy cycles.
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.
- Live-birth rate [ Time Frame: Live-birth after FET ]
- pregnancy rate [ Time Frame: 2 weeks after Embryo transplantation ]2 weeks after Embryo transplantation, people go urine HCG and blood HCG test，positive as pregnancy
- clinical pregnancy rate [ Time Frame: 5 weeks after Embryo transplantation ]5 weeks after Embryo transplantation,people go Vaginal B ultrasonic，being saw the gestation sac as clinical pregnancy
