<s>[INST] We consulted a Gynac yesterday...she told that the egg has got released from the ovary of my wife...She suggested us to have intercourse as the egg would be alive for about 48 hours...i wanted to know what are the chances of my wife becoming pregnant?? [/INST] Hi, Rightly said Egg has life of around 48 hrs, but is very healthy for 24 hrs only. Sperms stay alive for 3 days, that is 72 hrs. So chances of pregnancy is high if you have sex just before ovulation & also for next 2-4 days. Sperms should reach the tube first & then wait for the egg to come into tube, where they meet & form the baby. Then baby moves & fixes in the uterus. Chances of pregnancy in normal couple is only 10 %. That's because the healthy egg may not meet the healthy sperm always. Healthy doesn't mean you have a problem. Incidentally the egg or the sperm chosen may not be good. If you are lucky, you may be in that 10 % & you get the best sperm to meet the best egg & you have a healthy lovely baby. These are something's we cannot control. All the best, God bless you Chat Doctor.  </s>
