NCT02251925

Brief Summary

This study is a prospective randomized controlled trial to compare the pregnancy outcomes of frozen embryo transfer in natural and hormonal replacement cycles. The study population consisted of all infertile women with regular menstrual cycles who will undergo IVF/ICSI and frozen embryo transfer in Reproductive Biomedicine Research Center, Royan institute, Tehran Iran.

  • Ongoing pregnancy

    12 weeks

  • miscarriage rate

    12 weeks

Study Arms (4)

Natural cycle

EXPERIMENTAL

In natural cycle without hCG, daily monitoring of urinary LH is started from day eight of the cycle and frozen-thawed embryo transfer is planned 3-5 days after detection of LH surge, observing mature follicles in ultrasound and endometrial thickness over 7mm for cleavage embryos.

Biological: frozen Embryo transfer

Natural cycle + hCG for ovulation induction

EXPERIMENTAL

In natural cycle with hCG, after detection of mature follicles in ultrasound and endometrial thickness over 7mm, 10,000IU hCG is injected for ovulation and embryo transfer is performed 3-5 days later in cleavage stage.

Biological: frozen Embryo transferDrug: 10,000U hCG injection

Hormonally controlled cycle with GnRH-a

EXPERIMENTAL

In this group , injection of GnRH agonist (Superfact) at a subcutaneous daily dose of 0.5 mg is started on the day 17-19 of the natural menstrual cycle. Once pituitary desensitization is confirmed, hormonal treatment is commenced with 4mg/day oral Estradiol valerate and after 7 days if endometrial thickness is adequate, Estradiol administration will be continued with the same dose and 100mg Progesterone is administered before embryo transfer, otherwise patients are candidates for higher dosage of Estradiol till favourable endometrial thickness is achieved.

Biological: frozen Embryo transferDrug: GnRH agonist (Superfact)

Hormonally controlled cycle without GnRH-a

EXPERIMENTAL

In the hormonal group without GnRH-a, endometrial preparation will be started with daily administration of 6 mg Estradiol valerate from the 2nd day of the natural menstrual cycle for 6 days. Then treatment will be continued similar to the 3rd group.

Biological: frozen Embryo transferDrug: administration of 6 mg Estradiol valerate

Interventions

In this study all patients who will undergo frozen embryo transfer are randomly allocated to be prepared for transfer by using either natural cycle (with or without hCG for ovulation induction) or Hormonal cycle (with or without administration of GnRH-a).

Natural cycle + hCG for ovulation induction

In group 3, injection of GnRH agonist (Superfact) at a subcutaneous daily dose of 0.5 mg is started on the day 17-19 of the natural menstrual cycle. Once pituitary desensitization is confirmed, hormonal treatment is commenced with 4mg/day oral Estradiol valerate and after 7 days if endometrial thickness is adequate, Estradiol administration will be continued with the same dose and 100mg Progesterone is administered before embryo transfer, otherwise patients are candidates for higher dosage of Estradiol till favourable endometrial thickness is achieved.

Hormonally controlled cycle with GnRH-a

In the hormonal group without GnRH-a, endometrial preparation will be started with daily administration of 6 mg Estradiol valerate from the 2nd day of the natural menstrual cycle for 6 days. Then treatment will be continued similar to the 3rd group.
