Can 2 sperm fertilize the same egg?
Each is fertilized independently, and each becomes an embryo. With identical twins, one egg is fertilized by one sperm, and the embryo splits at some later stage to become two. Occasionally, two sperm are known to fertilize a single egg; this ‘double fertilization’ is thought to happen in about 1% of human conceptions.
Can twins be conceived on different days?
Although two fetuses develop simultaneously in superfetation, they differ in maturity, having been conceived days or even weeks apart. … Superfetation is suspected only when the twins are of different sizes and at different stages of development. It is typically noticed during a routine checkup on the ultrasound.
Can another man’s sperm affect a fetus?
But it takes two to make a baby, so what about the men? Recent research has shown that genes encoded in men’s sperm can be modifed by the environment in which they were developing, and those modifications may affect the developing child.
Can you mix two sperms together?
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 woman get pregnant while already pregnant?
In extremely rare cases, a woman can get pregnant while already pregnant. Normally, a pregnant woman’s ovaries temporarily stop releasing eggs. But in a rare phenomenon called superfetation, another egg is released, gets fertilized with sperm, and attaches to the wall of the uterus, resulting in two babies.

What happens when two different sperms meet?
What happens when sperm from two different males meet up? … Incapacitation is slightly different because it does not even require the sperm of the second mate. Instead, something in the seminal fluid destroys the ability of the first sperm to perform its duty of fertilising eggs.
Do babies look like surrogate mother?
So, if the surrogate is a traditional surrogate (meaning she contributed the egg in addition to carrying the baby), then yes — the baby will look like her. If, however, the surrogate is a gestational surrogate (meaning another woman’s egg was used to create the embryo), then the baby will not look like the surrogate.
