Key findings

What ClinicalTrials.gov does not surface for Polycystic Ovary Syndrome on its own pages , computed from the registry mirror as of 2026-08-08. Each line carries its own denominator so it can be quoted as it stands.

  1. Polycystic Ovary Syndrome is recruiting above its size-band peers.

    13 of 31 indexed trials (41.9%) are open to enrollment, against a 39.7% average across 762 conditions with 20-99 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

    University of Virginia accounts for 4 of 31 trials (12.9%). 26 distinct sponsors appear on at least one study for this condition label.

  3. Most Polycystic Ovary Syndrome trials plan to enrol fewer than 100 people.

    Median target enrolment is 70 among the 31 trials that report a genuine target (sentinel values excluded). 20 of those (64.5%) plan for fewer than 100 participants.
