Summary

We aimed to decrease quantity of exogenous estrogen and evaluated the success rate of ongoing pregnancy in women undergone artificial FET who have a surplus embryos at previous fertility treatment cycles.

In this study, endometrial prepared with standard long GnRH protocol and for luteal phase support patients received 6 mg oral E2 and intramuscularly P 100 mg/d and embryos on day 2-3 were transferred. Control group continued E2 until 12 week of pregnancy, while for cases after identify gestational sac with heart beat (the 6 week of pregnancy) by vaginal ultrasonography, E2 will discontinued.

Conditions

  • Infertility, Female
  • Frozen Embryo Transfer

Interventions

DRUG

Strogen

The OCP-LD begins in 2 to 3 days of the last menstrual cycle and then 500 μgr/d GnRH-a will received on day 17 for fourteen days. Then in 2-3 days of the next menstrual cycle, GnRH-a reduced to 200 μgr/d dose. the patients will receive 6 mg oral that will be continued for 14 days and during this time endometrium thickness evaluated by vaginal ultrasonography. If endometrial thickness is estimated ≥7mm, intramuscularly progesterone 100 mg/d will be started. After the onset of progesterone (days 17 to 18 cycles) frozen embryos transferred. Control group receive 6 mg oral estrogen and 100 mg intramuscularly progesterone until 12 week of pregnancy. The levels of maternal estrogen and progesterone was measured at the time of the starting day of progesterone (day 15), the day of embryo transfer, 6 and 12 weeks of pregnancy.

In patients 35 days after embryo transfer and observation of gestational sac with heart beat (6 weeks of pregnancy) by ultrasound, exogenous estrogen will discontinued while progesterone will remain daily use until twelfth week of pregnancy. The levels of maternal estrogen and progesterone was measured at the time of the starting day of progesterone (day 15), the day of embryo transfer, 6 and 12 weeks of pregnancy.
