Follicle Stimulating Hormone (FSH), Assisted Reproductive Technologies (ART), Follitropin Delta, REKOVELLE
Brief summary
The aim of the study is to explore how the individualized dosing regimen of REKOVELLE is used in routine clinical practice and to describe the effectiveness and safety of REKOVELLE under real-world conditions.
Interventions
The Intervention (solution for injection) is delivered with a pre-filled injection pen. The REKOVELLE dose will be based on a recent determination (within the last 12 months) of AMH (anti- müllerian hormone) measured by the ELECSYS AMH Plus Immunoassay.

| Treatment used for Luteal phase support (for naïve and non-naïve subjects) | From start of REKOVELLE treatment until 10-11 weeks after embryo transfer | Decided as a choice between Progesterone, Oestrogen and hCG |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of biochemical pregnancy (for naïve and non-naïve subjects) | Up to 10-11 weeks after transfer | Biochemical pregnancy is defined as positive beta hCG (βhCG) test but no gestational sac is observed on later transvaginal ultrasound, or menstruation is reported. |
| Incidence of spontaneous abortion (for naïve and non-naïve subjects) | Up to 10-11 weeks after transfer | Spontaneous abortion is defined as positive βhCG test but all intrauterine gestational sacs without fetal heart beat as documented by ultrasound, or there are no viable fetuses observed by ultrasound. |
| Incidence of elective abortion (for naïve and non-naïve subjects) | Up to 10-11 weeks after transfer | Elective abortion is defined as induced abortion done at the request of the woman for other than therapeutic reasons. |
| Incidence of vanishing twins (for naïve and non-naïve subjects) | Up to 10-11 weeks after transfer | Vanishing twin is defined as spontaneous disappearance of an intrauterine gestational sac with or without heart beat in a pregnancy where one viable fetus remains as documented by ultrasound. |
| Incidence of ectopic pregnancy (for naïve and non-naïve subjects) | Up to 10-11 weeks after transfer | Ectopic pregnancy is defined as extrauterine gestational sac with or without fetal heart beat as documented by ultrasound or surgery. |
| Proportion of subjects with cycle cancellation (for naïve and non-naïve subjects) | Up to 10-11 weeks after transfer | Cancellation could be done before oocyte pick up (due to poor ovarian response, excessive ovarian response, any illness which prevents oocyte collection procedure, subject not taking hCG injection at the correct time, subject choice, other) or after oocyte pick up (due to no oocytes collected, no oocytes fertilized, abnormal fertilization, abnormal embryo development, no embryo development, ovarian hyperstimulation syndrome (OHSS), subject choice, other) |
| Type of gonadotropin used (previous cycle information for non-naïve subjects) | At baseline | — |
| Dose of gonadotropin used (previous cycle information for non-naïve subjects) | At baseline | — |
| Duration of treatment with gonadotropin (previous cycle information for non-naïve subjects) | At baseline | — |
| Type of GnRH used (previous cycle information for non-naïve subjects) | At baseline | Defined as a choice between GnRH agonist and GnRH antagonist |
| Rate of Ongoing Pregnancy (for naïve and non-naïve subjects) | Up to 10-11 weeks after transfer | Ongoing pregnancy is defined as at least one intrauterine viable fetus, 10-11 weeks after first fresh or frozen embryo/blastocyst transfer. |
| Treatment used for the triggering of follicle maturation (previous cycle information for non-naïve subjects) | At baseline | — |
| Treatment used for Luteal phase support (previous cycle information for non-naïve subjects) | At baseline | Decided as a choice between Progesterone, Oestrogen and hCG |
| Number of oocytes retrieved (previous cycle information for non-naïve subjects) | At baseline | — |
| Number of embryos/blastocysts transferred (previous cycle information for non-naïve subjects) | At baseline | — |

| Proportion of subjects with preventive interventions for early OHSS (previous cycle information for non-naïve subjects) | At baseline | Preventive interventions cover triggering of final follicular maturation with GnRH agonist and fresh embryo/blastocyst transfer or cryopreservation of oocytes/embryos/blastocysts, cycle cancellation, coasting. |
| Proportion of subjects with preventive interventions for early OHSS (for naïve and non-naïve subjects) | Up to 10-11 weeks after transfer | Preventive interventions cover triggering of final follicular maturation with GnRH agonist and fresh embryo/blastocyst transfer or cryopreservation of oocytes/embryos/blastocysts, Cycle cancellation, Coasting. |
| Frequency of adverse drug reactions (ADR) (for naïve and non-naïve subjects) | From start of REKOVELLE treatment until 10-11 weeks after embryo transfer | An ADR is characterized by the causal relationship between REKOVELLE and the adverse event is at least a reasonable possibility. |
