Gov. Gavin Newsom signed SB729 Sunday.
The bill will require a large group health plan and disability insurance policies to provide coverage for infertility and fertility services, including IVF.
Newsom said in a statement, "We are proud to help every Californian make their own choices about the family they want."
The signing of this bill comes weeks after U.S. Senate Republicans blocked a bill that would guarantee access to in vitro fertilization nationwide.
The new law is expected to go into effect starting July 2025.
