When i was in school 20 years ago, they taught that sperm will die when exposed to air. But nowadays, I sometimes wonder if this is true because we put sperms in a jar and wash them for IUI and IVF. How come the sperms can survive for so long? Does anyone know???
Sophie, don't worry, you can't be pregnant. Don't let it bother you and study hard.
