During his 2024 campaign, President Donald Trump made a big promise to Americans seeking fertility care to start or expand their families.

“Under the Trump administration, your government will pay for — or your insurance company will be mandated to pay for — all costs associated with IVF treatment, fertilization for women,” he said at a campaign rally that August, referring to in vitro fertilization.

While the president has raised awareness about infertility and taken several steps aimed at making IVF more accessible much more needs to be done to fulfill that promise, reproductive medicine advocates and experts tell CNN.

Notably, his measures to date do not impose a mandate that IVF be covered by employers or others. Instead, he proposed a rule last week aimed at enticing more employers to voluntarily offer IVF benefits and has negotiated discounted cash prices for three popular fertility drugs on the TrumpRx website.

“The policies President Trump and the administration have proposed so far do not amount to full coverage or full access for those who need it,” said Usha Ranji, associate director for women’s health policy at KFF, a nonpartisan research group.
