Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Polycystic ovarian syndrome (PCOS) is a heterogeneous, multifaceted and complex disorder characterized by insulin resistance (IR), hyperinsulinemia, and hyperandrogenism leading ovarian disfunction and infertility. Given the central pathogenic role of IR in the endocrine, reproductive, and metabolic disturbances of PCOS, several pharmacological and non-pharmacological approaches have been proposed to counteract the hyper insulinemic IR typical of the syndrome. Two Inositol stereoisomers, Myo-Inositol (MI) and D-chiro-inositol (DCI), captured the attention of researchers for their insulin-sensitizing actions, which configure them as proper candidates for the treatment of PCOS.

Very few studies reported on spontaneous clinical pregnancy rates, none were powered for this outcome, and none reported on the clinically relevant outcome of live birth. Therefore, data about clinical pregnancy rate, live birth rate, and miscarriage rate comparing inositols with placebo are limited.

Nevertheless, regarding infertility the primary outcomes that should be considered are clinical pregnancy rate, miscarriage rate and live birth rate. Although many studies showed improved hormonal and metabolic profile and improved ovulation rate and higher quality and number of oocyte retrieved in Assisted Reproductive Technology (ART) in PCOS women after inositols administration, data about clinical pregnancy rate, live birth rate, and miscarriage rate are limited with several concerns regarding interpretation of the studies.

Furthermore, independently by the effect on PCOS related infertility, few data are available about the role of inositol on obstetrics outcomes of pregnancies conceived after treatment with inositol and/or orally supplemented during pregnancy. Considering that the combination of MI and DCI alleviate many of the metabolic dysregulations typical of PCOS thanks to insulin-sensitizing actions, it is plausible consider a beneficial effects on pregnancy complications such as gestational diabetes and preeclampsia.

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors
The patients, care provides, investigators and outcome assessors are blinded for the treatment: Inositol + Folic acid versus Folic acid alone. The treatment allocation is identified by code number before the study start, and will be revealed only after data analysis.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Inositol + Folic acid

Couples with PCOS infertile women, diagnosed according to the Rotterdam criteria, who access infertility center with conception desire. These women will receive oral supplementation with Inositol (Myo-inositol and D-chiro-inositol at 40:1 ratio) plus Folic acid before spontaneous conception until delivery.

Group Type EXPERIMENTAL

Inositol + Folic acid

Intervention Type DIETARY_SUPPLEMENT

Daily oral supplementation before spontaneous conception until delivery:

Myo-Inositol: 1100 mg D-chiro-inositol: 27.6 mg Folic acid: 400 mcg

Folic acid

Couples with PCOS infertile women, diagnosed according to the Rotterdam criteria, who access infertility center with conception desire. These women will receive oral supplementation with Folic acid before spontaneous conception until delivery.

Group Type PLACEBO_COMPARATOR

Folic acid

Intervention Type DIETARY_SUPPLEMENT

Daily oral supplementation before spontaneous conception until delivery:

Folic acid: 400 mcg

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria
