Study summary

Previous studies have demonstrated that Myo-inositol is capable of restoring spontaneous ovarian activity, and consequently fertility, in most patients with PCOS. The aim of our study is to investigate the role of folic acid conteined in the inositol preparation. The study group included 50 patients, randomly allocated to subgroup A (myo-inositol 1500 gr) and subgroup B (myo-inositol 2000 gr + folic acid 200 mcg). The investigation include menstrual pattern and hirsutism score evaluation, hormonal assays, oral glucose tolerance test, euglycemic hyperinsulinaemic clamp and lipide profile at baseline and after six months of treatment.

Inclusion criteria

  • women with PCOS diagnosed in accordance with Rotterdam Consensus Conference Criteria 2003
  • > 25 kg/m2
  • age 18-35 years

Exclusion criteria

Exclusion Criteria:

  • pregnancy
  • significant liver or renal impairment
  • other hormonal dysfunctions (hypothalamic, pituitary, thyroidal or adrenal causes for the clinical signs)
  • neoplasms
  • unstable mental illness
  • diagnosis of diabetes mellitus or impaired glucose tolerance
  • use of drugs able to interfere with gluco-insulinaemic metabolism for at least three months prior entering the study.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2012 to primary completion in Dec 2013, 23 months.

Of 202 non-industry interventional studies with no phase under Polycystic Ovary Syndrome, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 39. This study's 23 months is above that.

Counting every sponsor, half of 217 studies reached it within 18 months; a quarter within 7 and three quarters within 39.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 24, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
