How to warm up testicles if they’re too cold
Warming up cold testicles can be done safely and easily. Here are some tips:
Sitting. When your testicles are in close contact with your thighs, there’s less opportunity for air to reach them and disperse heat. Sitting is a natural way to warm them.
Clothing. Layers of clothing can help trap heat, but avoid tight underwear and pants, as they can drive up the temperature too much.
Hot shower or sauna. A hot sauna will warm up your entire body. But remember, as the temperature of your testicles rises to your normal body temperature and higher, the quality of your sperm will temporarily decline.
How to prevent cold testicles
To prevent cold testicles, consider these tips:
Dress appropriately for the weather. If you’re going to be outside in cold temperatures, a pair of long johns or sports tights under your pants is a good idea.
Take breaks from the cold water of a swimming pool, beach, or other body of water.
Follow the instructions carefully if using specially designed underwear or other products meant to cool your balls to improve your sperm count. Prolonged exposure to cold temperatures could injure the skin of your scrotum and possibly harm sperm production.
