SB 157 Wisconsin Senate · 2025-2026 Regular Session

Relating to: prohibiting gender transition medical intervention for individuals under 18 years of age.

SB 157 prohibits healthcare providers from performing or referring minors under 18 for specific gender transition medical interventions. The bill bans surgeries (like hysterectomy or mastectomy), puberty-blocking drugs, and supraphysiologic hormone treatments aimed at changing a minor’s body to align with a gender discordant with their biological sex (defined as female or male based on chromosomes, sex organs, and hormones). Exceptions apply for minors with genetic disorders of sex development, infections, injuries, or life-threatening conditions requiring immediate surgery. Violations could lead to license revocation for healthcare providers, with disciplinary processes outlined in the bill.
