NCT06005207

Brief Summary

This study is a single-center, randomized, controlled prospective study. Those patients with repeated implantation failure (RIF) who will recieve frozen thawed embryo transfer (FET) are enrolled in the study. To determine the effect of vaginal progesterone on the clinical pregnancy outcomes of RIF patients.

Outcome Measures

Primary Outcomes (1)

  • Embryo implantation rate

    The proportion of the number of implanted embryos to the total number of transferred embryos is the embryo implantation rate.

    45 days after embryo transfer

Secondary Outcomes (4)

  • Clinical pregnancy rate

    45 days after embryo transfer

  • Early pregnancy loss rate

    12 weeks after embryo transfer

  • Persistent pregnancy rate

    20 weeks after embryo transfer

  • Live birth rate

    40 weeks after embryo transfer

Study Arms (2)

Vaginal progesterone supplementation

EXPERIMENTAL

90 mg progesterone vaginal sustained-release gel is added daily to induce endometrial transformation and luteal support

Drug: progesterone vaginal sustained-release gel

Regular progesterone

NO INTERVENTION

No additional vaginal progesterone gel, routine endometrial transformation and luteal support drugs

Interventions

90 mg progesterone vaginal sustained-release gel is added daily during endometrial transformation and luteal support

Vaginal progesterone supplementation

You may qualify if:

  • Aged between 20 and 40 years old;
  • BMI: 18-28 kg/m2;
  • Consistent with the diagnosis of repeated implantation failure of unknown reasons, the previous embryo transfer situation meets one of the following:
  • Total embryos transferred ≥ 4 high-quality cleavage-stage embryos; ≥ 2 blastocysts; ≥ 2 high quality cleavage-stage embryos +≥ 1 blastocysts;

  • Adverse pregnancy history (stillbirth, fetal malformation, etc.);
  • Severe paternal factors: need for TESA or PESA;
  • PGT;
  • Failure of embryo implantation due to any definite reason, including but not limited to: endometrial adhesion (moderate to severe), thin endometrium (\<7 mm before transformation), endometritis, endometriosis (medium or severe), adenomyosis, untreated hydrosalpinx, hysteromyoma (submucosal fibroids, non submucosal fibroids \> 4.0 cm and/or endometrial compression), reproductive malformation, serious immune disease, serious coagulation function abnormality;
  • Chromosome abnormality of either spouse;
  • Those with contraindications to pregnancy or assisted reproductive technology.
