Design outcomes

Primary

MeasureTime frame
Main Objective: To study if the pregnancy rates (COPR: cumulative ongoing pregnancy rate) after 3 treatment cycles with inositol are comparable to 3 cycles of ovulation induction with clomiphene citrate.;Secondary Objective: To investigate whether the compliance for the patient is acceptable. Therefore, potential adverse events (e.g. ovarian hyperstimulation syndrome), the occurrence of ovulation, cancelling of treatment cycles, and multiple pregnancies are registered. ;Primary end point(s): Pregnancy rates (COPR: cumulative ongoing pregnancy rate);Timepoint(s) of evaluation of this end point: After 3 treatment cycles of inositol (study group) or 3 ovulation induction cycles with clomiphene citrate (control group)

Secondary

MeasureTime frame
Secondary end point(s): Live birth rate number of gestational sacs number of cancelled treatment cycles and persistent anovulation;Timepoint(s) of evaluation of this end point: 32-42 weeks after conception at the time of the first ultrasound (around 7 weeks) during the study
