No - once one spern gets into the egg it immediately develops a hard shell to prevent others from getting in. It is possible though for a woman to give birth to fraternal twins that have two different fathers.
meld1707 - you defined identical twins in which case you are right - one sperm, one egg. But fraternal twins are two separate eggs and two sperm. You are the one that needs to do your homework.
Reading some of the other posts (and many other Qs and As that I have seen)- it really is scary what people 'know' about reproduction.

Yes and no.
Yes - a woman can get pregnant by 2 different men if she has 2 eggs develop at the same time (twins). This means that she is either having a 3-some or has hopped out of one bed and into the next in a short amount of time.
No - one baby will not have the dna of 2 different fathers. One egg and one sperm. That is it. Once a sperm enters the egg, all the other sperm are blocked.
To be a littler freakier - if she has 3 eggs (tripletts), she could have 3 different dads for one pregnancy, but poor kids to be born to a woman with such low morals!

No, this is impossible. DNA (deoxiribose neuclaic acid) has a signiture which is unique to it's own. Sperm cells which contain the DNA and the genetic-code of that one person (man), cannot intermingle and become a combination of two separate individuals. These are elementary facts which are learned in the ground-floor level of microbiology. If you have had sex with two men, and you become pregnant, that pregnacy comes from one of the men...not a combination of both. This is HOW genetic DNA tests can prove who the TRUE father is...by a simple DNA test which can match that one and only "father". Do some reading from a book on microbiology and reproduction...you will learn and acheive more answers than than you can file.

No. However, you CAN have "twins" that have two different fathers though. If you happen to release two eggs, have sex with two men and those two men both have sperm that fertilize both eggs. That was on msn.com website a couple of weeks ago and I was freaked out by that. Evidentally, it has happened many times. The first documented case occured during slavery times when a black woman had a black child AND a mixed child. Things that make you go hmmmmm.

When an egg beomes fertilized a hormone is released that makes the other available eggs' shells harden so a sperm can't get in. I suppose if you were having sex with both men at the same time there might be a very tiny chance that two eggs would get fertilized at the same time, but I wouldn't bet on it happening. If you want to have babies from two different men you will either need to use artificial insemination or you will have to have them one at a time.

I seriously doubt that that could happen. The only thing I could see happening is if the men ejaculated in the woman very close together, like SECONDS, and one sperm from each man impregnated 2 eggs and she had twins with two different fathers. That's the only thing I see happening, but I could be wrong!

If a woman had sex with 2 males in a close amount of time, and released 2 eggs (twins), and one male's sperm penetrated one egg, and the other male's sperm penetrated the other egg, then she could be pregnant by both at the same time. But, neither child would share any of their opposite father's DNA. They would only share in their mother's DNA. This phenomenon has been dubbed in medical literature as heteropaternal superfecundation.

Only one sperm can fertilize one egg. The male sperm has half the chromozones and the egg has the other half needed to make one individual. It is impossible that one man gives 1/4 of the chromozones and the other man gave the other 1/4.
There is a possibility that if you had two eggs already then the sperm of number 1 man could fertilize one egg and the sperm of number 2 man could fertilize the other. In this case they would be fraternal twins.

No, only one sperm can fertilize the egg and that would carry only the DNA make up of the father who produced it. In the case of twins however, it is possible to have to different men be the fathers if each of their sperm fertilizes one of the eggs. This is very rare but has occurred.

I do not believe so but I know twins can be born with two separate fathers because of two eggs being impregnated within a short time.
