NCT05759871

Brief Summary

The aim of this study is to compare the efficacy of a protocol using FSH alone with that of a protocol using FSH plus a GnRH antagonist for controlled ovarian hyperstimulation in cycles of elective freezing in the context of a donor/recipient programme.

Outcome Measures

Primary Outcomes (2)

  • Rate of LH secretory peaks

    A secretory peak of LH is defined as the increase at levels ≥10 IU/l.

    3 weeks after start of ovarian stimulation.

  • Rate of concentration of progesterone >1 ng/ml

    Concentration of progesterone elevation \>1 ng/ml

    At any time within 3 weeks after start of ovarian stimulation.

Secondary Outcomes (2)

  • Rate of ongoing clinical pregnancy

    12 weeks after last menstrual period

  • Rate of miscarriage

    Within 20 weeks after last menstrual period

Other Outcomes (2)

  • Total dose of gonadotrophins (rFSH)

    2 weeks after last menstrual period

  • Number of retrieved cumulus oocytes complexes (COCs)

    3 weeks after last menstrual period / and start of ovarian stimulation

Study Arms (2)

FSH only (no GnRH antagonist)

EXPERIMENTAL

Women receive only FSH starting on day 2 of the cycle. The starting dose of FSH is 225-300 IU s.c. for the first 4 days adjusted thereafter according to the ovarian response.

Other: GnRH antagonist

FSH + GnRH antagonist

ACTIVE COMPARATOR

Women receive 225-300 IU s.c. FSH, and a GnRH antagonist from day 6 of FSH treatment at the dose of 0.25 mg per day until the triggering day. The GnRH antagonist in group 2 is injected each time immediately after the injection of FSH.

Other: GnRH antagonist

Interventions

The GnRH antagonist in the control group (standard therapy) is administered from day 6 of FSH treatment at the dose of 0.25 mg per day until the triggering day and is injected each time immediately after the injection of FSH.

Eligibility Criteria

Age21 Years - 32 Years
Sexfemale
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • healthy women 21-32 years old with a BMI of 21 to 29 kg/m2 who wish to donate their oocytes
