Can 2 different men get a woman pregnant?
It is possible for twins to have different fathers in a phenomenon called heteropaternal superfecundation, which occurs when two of a woman’s eggs are fertilized by sperm from two different men. Ordinarily, a woman becomes pregnant because one of her eggs has been fertilized by sperm.
How common are twins with different fathers?
Having twins from different fathers is an extremely rare event. One study found that twins with different fathers occurred in 2.4% of all fraternal twins whose parents had been involved in a paternity lawsuit. Even though 2.4% might seem like a high percentage, this study only researched a small number of pregnancies.
Can two sperm cells be combined?
Combining two sperm wouldn’t work (there aren’t enough goodies in a sperm to sustain an embryo early on) but maybe you could add two sperm to an egg in which you have removed the DNA. You’d end up with a child with just a bit of the donor’s DNA but the fertilized egg would have the DNA of both dads.
Can a child have two men’s DNA?
It raises the possibility of so-called “two-dad babies” – children born using sperm from one man, and some kind of other cell derived from a second man. For a fertilised egg to divide and form an embryo, it also needs to reprogram the genes of the sperm.
Does each sperm create a different baby?
Identical twins have the same genetic material, but as you can see, every egg they both make is different. Every sperm a man makes is different. Hence the chances of their babies being identical are pretty close to zero.
Can you have triplets with different fathers?
The Times said the phenomenon of twins or triplets having different fathers can occur when a woman, having ovulated at least twice in the same cycle, sleeps with more than one man within 24 hours and conceives children by them. The children, one of whom died after an illness in 2001, are now 10.
