In brief: Unknown.

Likely not. If sperm that are "cold" or less than body temperature are placed in the female, they will rapidly increase their temp to 98.
6. At that point it is likely that pregnancy could occur. Sperm are very tough in the lab and can still be motile 24+ hours after sitting at room temperature. Be careful.
