The measure would prevent health insurers from excluding benefits for outpatient expenses related to in vitro fertilization, in which the egg is fertilized outside a woman’s body and the embryo is implanted in the uterus. Under current law, insurers only have to provide the benefit for someone using a husband’s sperm. That has precluded female same-sex couples from coverage.
