The Puerto Rico Senate voted 21 in favor, 5 against on Wednesday to approve House Bill PC 164 banning transgender athletes from school and university sports teams aligned with their gender identity. ^[1] The amendment requires the proposal to go to a conference committee before final approval, postponing the outcome of one of the most controversial legislative debates of the term. ^[2] The PPD, PIP, and Proyecto Dignidad all opposed the measure unanimously. ^[3] Bill PC 164 requires medical verification including anatomical, genetic and testosterone testing for any student athlete whose sex is disputed. ^[4] Puerto Rico Department of Health stated the bill's sex verification requirements would violate privacy, cause psychological trauma and discriminate against trans students. ^[5] The amended version of PC 164 will now return to the Puerto Rico House of Representatives for reconciliation before being sent to the governor. ^[6] The key change involved removing provisions regarding the statute's implementation, leaving negotiations between legislative bodies open. ^[7]
