Key findings

What ClinicalTrials.gov does not surface for Contraception 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. Contraception is recruiting below its size-band peers.

    16 of 73 indexed trials (21.9%) 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.

  2. Sponsorship of Contraception trials is spread across many organizations.

    University of Utah accounts for 6 of 73 trials (8.2%). 42 distinct sponsors appear on at least one study for this condition label.

  3. Typical Contraception enrolment sits around 150 participants.

    Median target enrolment is 150 among the 73 trials that report a genuine target (sentinel values excluded). 30 of those (41.1%) plan for fewer than 100 participants.

  4. Contraception research is mostly interventional.

    57 interventional and 16 observational studies make up this index (78.1% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
