简要总结
The purpose of this observational study is to examine the development and appearance of embryos before and after freezing following a single controlled ovarian stimulation cycle using REKOVELLE® (follitropin delta) as the recombinant follicular stimulating hormone (rFSH) for controlled ovarian stimulation. The primary objective of the study is to examine how specific factors of embryo development or appearance are related to the chance of becoming pregnant.
The ovarian stimulation protocol with REKOVELLE®, a new rFSH prescribed for ovarian stimulation, is individualised with a dosing regimen that is based on two parameters: the body weight and the level of a hormone, the anti-Müllerian hormone, (AMH), a parameter used to predict how the ovaries will respond to the ovarian stimulation.

结局指标
主要结局
Clinical pregnancy rate
时间窗: 7 weeks after each embryo transfer
Clinical pregnancy is defined as at least one intrauterine gestational sac with fetal heart beat at week 7, from frozen thawed blastocysts. The correlation between morphological parameters (blastocyst score, timelapse score, blastocoele re-expansion) and clinical pregnancy rate will be assessed.
次要结局
- Use of the algorithm-based individualized dosing regimen with REKOVELLE®(At the day of the consultation visit where the daily dose of REKOVELLE® is decided)
- Day of REKOVELLE® stimulation start(At the day of the first REKOVELLE® injection during the ovarian stimulation treatment)
- Any deviation in REKOVELLE® administration(From day 1 up to day 20 of REKOVELLE® stimulation)
- Daily dose of REKOVELLE® administered(From day 1 up to day 20 of REKOVELLE® stimulation)
- Day of REKOVELLE® stimulation end(At the day of the last REKOVELLE® injection during the ovarian stimulation treatment)
- Cumulative clinical pregnancy rate(Up to 24 months)
- Positive βhCG result (blood or urinary pregnancy test)(Up to 24 months)
- Number of days of treatment with REKOVELLE®(From day 1 up to day 20 of REKOVELLE® stimulation)
