Aah! That's the magic of the amazing scrotum! There is a countercurrent heat exchanger made up of the arrangement of blood vessels that essentially isolates the scrotum from the heat of the rest of the body. Because of this, the testes stay cool even if the body is warm.

This arrangement is taken to extremes in dolphins and whales (which have no external scrotum), which run blood vessels through their fins to cool it, and then direct the cooled blood to their (internal) testes.

I like how she said that she was 'lucky' to dodge her attacker, even though she is a martial arts expert. Linked article says that one of the boys then pulled a knife, and she decided to de-escalate the fight. By then 911 had been called by witnesses. Overall, the woman took restrained action and kept herself safe.
