What this trial studies

This interventional program gives adolescent females (14–19 years, at least 3 years after menarche) a combined supplement regimen containing myo‑Inositol, α‑lactalbumin, Dioscorea villosa, and vitamin D to address oligomenorrhea or amenorrhea. Participants with primary amenorrhea, other endocrine disorders, or recent hormonal or relevant supplement use are excluded. The supplements are provided at doses commonly sold commercially and are intended for repeated use over the treatment period. The main outcome is improvement in menstrual cycle regularity in patients with and without PCOS, with visits conducted at participating centers in Georgia, Italy, and Russia.

Who should consider this trial

Good fit: Girls aged 14–19 who are at least three years post‑menarche, have oligomenorrhea or amenorrhea, are not using hormonal therapies or the study supplements, and do not have other endocrine disorders are ideal candidates.

Not a fit: Patients with primary amenorrhea, hyperandrogenism from other causes, hyperprolactinemia, overt hypothyroidism, other hormonal abnormalities, or recent use of hormonal treatments or myo‑Inositol/Dioscorea supplements are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the regimen could help restore more regular menstrual cycles in adolescents and offer a non‑hormonal option for managing cycle irregularities.

How similar studies have performed: Myo‑Inositol has shown benefit for menstrual regularity and metabolic features in adult PCOS in prior studies, but combining it with Dioscorea villosa and testing this approach in adolescents is relatively untested.
