Please clarify: I am not sure if we are talking about the same things. Sperm are often frozen at sperm banks and saved for future use. But, in general in real life there are no such 'cold environments' when it comes to daily living or anatomy. What context are you asking about? Ejaculated sperm die very quickly in air whether it is hot or cold. The only sperm that can survive after ejaculation are in the vagina.
