Drug:
• Myo-inositol
2 x 1 bag per day, per os (subjects can take myo-inositol during the meal but it is not obliged).
• Clomiphene Citrate
Each tablet contains 50 mg of clomiphene citrate which means 33,9 mg of clomiphene.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Rate of cumulative ongoing pregnancy (a pregnancy diagnosed by ultrasonic visualisation of one or more gestational sacs with fetal heart beat) after 3 treatment cycles with inositol versus clomiphene citrate for ovulation induction.	Recently, a meta-analysis on the use of inositol in PCOS was published. This study showed that inositol leads to a more regular menstrual cycle and recovery of ovarian function. Less data are present on pregnancy rates. No RCT was found on the comparison between inositol and the golden standard first line treatment of ovulation induction, namely clomiphene citrate. Another advantage of inositol is that it doesn't have side effects compared to metformin and that there is no elevated risk on multiple pregnancies, which is the case with clomiphene citrate.	At 7 - 8 gestational weeks
Secondary	The number of potential adverse events	The potential adverse events will be measured to determine whether the compliance for the patient is acceptable.	During 3 consecutive treatment cycles (each treatment cycle is up to 5 weeks)
Secondary	The occurrence of ovulation	The occurence of ovulation will be measured to determine whether the compliance for the patient is acceptable.	During 3 consecutive treatment cycles (each treatment cycle is up to 5 weeks)
Secondary	The number of cancelled treatment cycles	The number of cancelled treatment cycles will be measured to determine whether the compliance for the patient is acceptable.	During 3 consecutive treatment cycles (each treatment cycle is up to 5 weeks)
Secondary	The number of multiple pregnancies	The number of multiple pregnancies will be measured to determine whether the compliance for the patient is acceptable.	During 3 consecutive treatment cycles (each treatment cycle is up to 5 weeks)
