Scientific titleA randomised controlled trial of 225 versus 300 IU recombinant follicle stimulating hormone (FSH) for ovarian stimulation in predicted normal responders by antral follicle count
Study objectivesTo test the hypothesis that, among women predicted to have a normal ovarian response, ovarian stimulation using 300 IU follicle stimulating hormone (FSH) results in retrieval of more mature oocytes than 225 IU.

As of 05/04/2012, the anticipated end date of trial has been updated from 01/10/2008 to 01/04/2008.
Ethics approval(s)Obtained from National Health Service (NHS) research ethics committee on the 14th September 2008 (ref: 06/MRE04/33).
Health condition(s) or problem(s) studiedInfertility
InterventionConventional controlled ovarian stimulation using a fixed daily doses of 225 IU or 300 IU of recombinant FSH. The total duration of treatment is 6 weeks with 2 weeks of the research medication and up to 8 weeks of follow up.
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Follicle stimulating hormone (FSH)
Primary outcome measureNumber of mature oocytes retrieved, measured at about 2 - 3 weeks of starting the research medication.
Secondary outcome measures1. Number of follicles measuring more than 10 mm and more than 14 mm in diameter on the day of human chorionic gonadotropin (hCG) administration
2. Cycle cancellation due to poor ovarian response
3. The number of frozen embryos
4. The prevalence of moderate or severe ovarian hyperstimulation syndrome (OHSS)
5. The clinical and on-going pregnancy rates

Measured at 10 weeks at the latest.
Overall study start date01/10/2006
Completion date01/04/2008
