Hello,
Actually, sperm could only live for a few hours (2 to 3 hours) after ejaculated.
However, that is if the guy did NOT ejaculated anywhere near the girl's vagina. If he DID ejaculated near, on, or in the vagina, then it becomes a little bit more complicated. Here's the break down:
--If no fertile fluid is present, sperms will die within a few hours, usually when the semen is all dried up.
--If the guy happens to ejaculated near the genital area, or on the vagina (still consider as coming outside, not inside yet), the sperms still can SWIM into the vagina, and go inside the girl's body.
--Once the sperms are inside the girl's body, they can survive for 3 to 5 days.
--A lot of these sperms will die because the girl's body constantly produces a type of cervical fluid (calls "mucus") that is very acidic. Now, ironically, the mucus will eventually change and actually help keep sperms alive for about 3 to 5 days. (I don't remember when, where, and how the mucus does that, sorry, I forget like over half of what I learn, hehehe, my mind is bad like that =P)
--Also, if the condition is good (strong sperm, good vagina condition, etc.), sperms can survive a maximum of 7 days within a girl's body.
And 48 hours around the ovulation time is actually the time that the girl is fertile.
Hope this help,
