AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for women aged 18 to 35 with polycystic ovary syndrome (PCOS) who want to become pregnant and are starting clomiphene citrate to trigger ovulation.
- Age
- 18 to 35 years
- Sex

- Disease stage
- Polycystic ovary syndrome (PCOS) as defined by the Rotterdam criteria: at least two of three signs (many small follicles in the ovary, a cycle disorder, high male hormones).
- Earlier treatment
- Never treated with clomiphene citrate (CC), or an earlier CC treatment stopped more than 3 months ago.
- Biomarker or test result
- High antral follicle count (more than 19 per ovary) is one of the three signs of PCOS; at least two of the three are needed.
Main reasons for not taking part

- Original description
The main objective will be to check if MyoInositol (MYO) reduces the total resistance rate to Clomiphene Citrate (CC). For this, our study will be controlled, randomized and double blinded. It will include patients with PCOS (polycystic ovary syndrome, defined by the Rotterdam criteria) who wish to become pregnant and are eligible to simple ovulation induction by CC. Half of them will receive MYO + levomefolic acid (5-MTHF) in addition to the CC, while the other half will receive a placebo containing only 5-MTHF in addition to the CC. The MYO supplementation will be initiated at least one month before taking CC and will be continued throughout this treatment until pregnancy or before switching to another type of treatment for ovulation induction if no pregnancy is obtained after 6 ovulatory cycles.Read full original descriptionShow less
Interest of Myo-inositol Supplementation in Women With Polycystic Ovarian Syndrome During Induction of Ovulation With Clomiphene Citrate
The main objective will be to check if MyoInositol (MYO) reduces the total resistance rate to Clomiphene Citrate (CC). For this, our study will be controlled, randomized and double blinded. It will include patients with PCOS (polycystic ovary syndrome, defined by the Rotterdam criteria) who wish to become pregnant and are eligible to simple ovulation induction by CC.

Inclusion: Wishing pregnancy,; Having PCOS defined by the Rotterdam criteria: high antral follicle count (AFC) (> 19 per ovary) and/or a disorder of the cycle and/or hyperandrogenism (at least two of the three criteria),; Having never been treated with CC (or previous treatment with CC interrupted for > 3 months); Having received complete information and having signed consent; Covered by social security.
Exclusion: Intolerance to CC in previous treatment,; History of ovarian drilling,; BMI > 35,; Other associated cause of oligoanovulation requiring specific treatment (eg., Hyperprolactinemia or functional hypothalamic anovulation),; Ongoing pregnancy at the time of CC initiation,; Other male or female cause of hypo-fertility,; Negative rubella serology.
