Fox News host Tucker Carlson asserted on Sunday that "science" was on the side of a doctor claiming male Hillary Clinton supporters suffered from low testosterone.

"A doctor [is] under fire for claiming men who support Hillary Clinton likely suffer from low testosterone," Carlson teased before a commercial break. "It's science. You can't deny it."

"Are you a Low T denier?" he quipped.

Following the break, Carlson explained that Fort Myers Dr. Dareld Morris was offering a free testosterone test to men who support the Democratic nominee.

"The question is, can you argue with science?" Carlson said.
