About a year ago I got into taking ice baths, to recover from hard running workouts that I was doing. Not doing any research, I stupidly made the water very cold (possibly around 40 degrees, maybe a little under - way colder than what is recommended) and submersed my legs and lower stomach into the bath. I only took baths such as this once or twice, and only for a duration of 8-10 minutes. Could my testicles have been harmed in anyway?? My legs were pretty numb after the bath for like 15 minutes, but I felt normal after that. No pain or any signs of actual injury. After learning that ice baths should not be colder than like 45 degrees, I am kind of worried I could have harmed my fertility. I know, I am probably being neurotic, but I am just looking for some piece of mind about this.
When I think of the fact that people go ice/winter swimming in water that is literally freezing, I think that I must be okay, but... I am still a bit unsure...
