Contraception requirements for participants assigned Female at Birth and of Childbearing potential

If the partner assigned female at birth and of childbearing potential is not pregnant, additional contraception recommendations should also be considered.

Participants assigned male at birth must also refrain from sperm donation and cryopreservation of sperm cells during treatment and until the end of contraception requirement.
