This was done to cater to the “men” on campus who were born female.

University of Wisconsin-Madison offers free tampons in men’s bathrooms

The University of Wisconsin-Madison is rolling out a new pilot program to provide free menstrual products in several of its campus bathrooms — including some men’s restrooms.

The public university will offer the women’s hygiene products in three campus buildings. In two of them, Helen C. White and Sterling halls, the products will be available in all of the women’s restrooms, said Steve Wagner, a spokesman for the school, in an email to The College Fix.

But in a third venue, the Red Gym, the products will be available in all of the building’s bathrooms, he said.

Asked why women’s hygiene products are needed inside men’s bathrooms, Wagner said: “Menstrual products will be available in all of the bathrooms of the Red Gym so that they are available to any student who might need them.”

It appears the products are needed in men’s bathrooms to benefit transgender males (biological women who identify as male).

The three-level Red Gym houses the institution’s Lesbian, Gay and Transgender Campus Center, the Office of Multicultural Arts Initiative, Multicultural Student Center and a variety of other student and academic programs and divisions, according to its website.
