Registered outcomes7
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Emergence of an ovarian follicular wave after dominant follicle aspiration or hCG administration | One year | Evaluate if the aspiration of the dominant follicle is able to induce a follicular wave to emerge. Evaluate if administration of hCG is able to induce ovulation of a dominant follicle larger than 16mm and to induce a follicular wave to emerge. A follicular wave emergence is defined as an increase in the number of ovarian follicles smaller than 10mm seen at the transvaginal ultrasound scan after the interventions |
| Primary | Follicular growth pattern on ultrasound scan | One year | Evaluate with periodic transvaginal ultrasound scan the size (mm), number and growth rate (mm/day) of ovarian follicles in each of the three groups |
| Secondary | Estradiol and progesterone levels during ovarian stimulation | One year | Evaluate blood levels of estradiol (pg/mL) and progesterone (ng/mL) during ovarian stimulation in each of the three groups at each visit to evaluate the progress of treatment. |
| Secondary | Number of mature oocytes retrieved | One year | Evaluate the number of metaphase II oocytes retrieved in each of the three groups |
| Secondary | Total dose of gonadotrophins used | One year | Total dose of gonadotrophins (in international units) necessary to stimulate the ovaries (from the first day of stimulation until the last dose of recombinant FSH administered before the oocyte retrieval) |
| Secondary | Fertilization rate | One year | Number of embryos formed in relation with the number of oocytes inseminated |
| Secondary | Pregnancy rate | One year | Positive beta hCG determination on blood 10 days after embryo transfer |
