Hey @benedikt-hartmann , thanks for bringing up this topic! Can you describe a bit more why you're interested in this? Only from a fertility perspective or are there other longevity aspects to look at?

I do my weekly 82°C sauna sessions without any cooling. You’re right @benedikt-hartmann, this whole topic has blown up since Bryan Johnson started posting his new sauna protocols.

Anyone in the community with expertise in sauna or male fertility?

What I understand is that cooling your testicles has no effect on long term markers or longevity. It only protects the batch of sperm that was already produced. It makes sense to cool them if you are planning to get a child with your partner at the moment or if you want to test or donate your sperm.

I’m so many years of going to sauna I’ve never seen someone with ice between his legs. Even if it’s useful I don’t believe this will ever be normal in Germany.
