Hormone gel transfer: does washing or clothing protect women?
NCT ID NCT02994602
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether washing the skin or wearing a shirt can stop a hormone gel (Nestorone + testosterone) from transferring from men to women during skin contact. Healthy men applied the gel, then women touched the application site under different conditions. The goal was to measure changes in women's hormone levels to understand how to prevent accidental exposure.
