No! sperm cells live inside a woman for up to 48 hours. By 48 hours if it hasn't fertilized any of the female's eggs than the sperm cells die.
No, this is not true. Like the above poster stated, sperm can only live around 2 days (up to 5 in some cases).
This is why, if you're trying to conceive, you have best chances if you intercourse the couple of days leading up to ovulation.
No, sperm can only survive for 48-72 hours. So t is possible to conceive 2-3 days after sex during ovulation if it is the right time. But 2 weeks is way too long.
