Salt Lake City, UT—A trans woman was rushed to the hospital this week after getting kicked in the junk.

Doctors and medical experts are mystified by the case and are still unable to locate the source of the woman’s pain.

The Netflix Series Unsolved Mysteries has announced a full episode dedicated to the incident. The episode, titled, “Ouch! My Balls!” will air next Thursday, and feature special guest star Caitlyn Jenner.
