The move comes as the government says sexually transmitted diseases are on the rise among young people, and as this year's exceptional inflation is cutting especially deeply into the budgets of France's poorest.

Girls and women aged 25 and under already can get free birth control in France as part of government efforts to ensure young people of all incomes can prevent unwanted pregnancy.

Existing measures do not apply to men, however, or specifically address access for transgender or nonbinary people.

Macron had said on Thursday that condoms would be free in pharmacies for anyone 18-25 starting on January 1, but after a French TV presenter and others challenged him on social networks on Friday over why the condom measure did not include minors, the president agreed to expand the program.

"Let's do it," Macron said in a video that he shot from the sidelines of a summit in Spain. He later tweeted: "A lot of minors also have sex ... they need to protect themselves too."

Macron also promised stepped-up efforts to prevent and test for HIV and other sexually transmitted viruses.

France's state health system covers some birth control costs but not all, and doctor appointments for low-income patients often require long waits. Abortions in France are available free for everyone.

Several other European countries offer free or subsidised contraception.
