Is it medically possible for two men to father twins with one woman?

Answer 1

Yes, if they are fraternal twins.

With identical twins, the nucleus of the fertizlized egg splits, creating two genetically identical embryos.

With fraternal twins, you have two eggs released at the same (approximately) time, separately and independently fertilized by different sperm cells. If there's more than one person's sperm present, and two eggs, you could, potentially, have non-identical twins of different parentage - half-siblings, but twins.

Answer 2

Fraternal twins are formed when two separate eggs are fertilized by two sperms. If a woman has contact with different partners within her fertile time period (5-7 days) and has multiple ovulations, it is possible for her to have fraternal twins or even triplets with different fathers. This phenomenon has been dubbed in medical literature as heteropaternal superfecundation.

Cincinnati, OH. U.S.A. December 13, 2005 — DNA Diagnostics Center (DDC), a leading DNA testing company, reports several cases of twins that DNA paternity testing proved to have different fathers. Such occurrences, although rare, are being more frequently revealed via DNA testing.

Answer 3

Yes it is very possible. That happened to my mom. She has a set of fraternal twins with two different dads. A paternity tests was done with one of the men and he was 99.9 percent positive for one but not the other. i know its a weird thing but it does happen and they are 15 years old now so evidently its been happening in the world a while, i guess people just dont think things like that can happen

Answer 4

Well I know it's possible for cats to have kittens from different fathers. Of course a cat in heat is a whore. But never the less, I don't see why it would be any different with a woman. If she ovulates two eggs and has sex with two men, why wouldn't each man be able to fertilize one egg. Makes sense but probably doesn't happen very often.
On a side note: I wonder if the two sperms that don't know each other have a jousting match to win the egg????

Answer 5

yes it is possible for a woman to release 2 eggs have sex with two men within those days and have each egg fertilized by a different man and have non identical twins with different fathers it has even happen before! look it up online there loads of info about this sort of thing, just make sure you check reliable pages.

Answer 6

If you watch Days of Our Lives...then yes!!

It's possible for a woman to ovulate more than one egg at a time...so I would assume that it could be *possible* for two men to father separate twins....now do I feel it likely? Nope, not in a million.

Why? Because the sperm are supposed to keep swimming until all the eggs are fertilized...I would think that unless it was a three-some (or more) having sex literally at the same time....then the likelyhood of one egg remaining unfertilized for a day or so until the mother had sex again I think is slim ot impossible.

Answer 7

i think of I heard of this taking place while i became watching divorce court docket on television. the female had fraternal twins yet they had distinctive fathers. Its extremely uncommon. a million in 12 instruments of fraternal twins have distinctive fathers (the 1st rate term for that's bi-paternal, meaning 2 fathers). yet fraternal twins make up 2% of the worlds inhabitants. And intercourse would not would desire to ensue minutes aside for this to ensue. all of it has to do with ovulation, the quantity of time it takes for each mans sperm to realize the egg, stuff like that. Like, if a woman had intercourse with greater effective than one guy quite a few days till now ovulation, the sperm will attain the fallopian tubes till now the eggs get there and lie in wait. as quickly as the egg arrives interior the tube, it actual relies upon on who's the fortunate wiggle malicious software that makes it interior the egg and fertilizes it. no rely the way you look at it, its an extremely outstanding occurance.

Answer 8

I imagine if it were medically possible the woman would have had to release two eggs that cycle resulting in fraternal twins. She then would have had to have sex with both men during her fertile time.

Answer 9

I guess theoretically it is possible for fraternal twins to have different fathers since they are from two eggs being fertilized by two different sperm. I'm sure the chances are pretty slim though!!!

Identical twins, that would be impossible because they are from one fertilized egg.

Answer 10

Yes, if the woman released 2 eggs and she had sex w/ 2 men right around ovulation. They would be fraternal twins (not identical)
