Twins with Different Fathers
Did you know that fraternal twins can have different fathers?
When two egg cells are fertilized by two sperm cells in the same period of time, fraternal twins are formed. So, if a woman’s ovaries release more than one egg during ovulation and the woman has contact with more than one man during her fertile period, it is possible that she will become pregnant with twins who have different fathers. This phenomenon is extremely rare, but possible.
In even rarer cases, fraternal twins from different fathers may result from mistakes made during assisted fertility procedures. For instance, if a woman is artificially inseminated with a mixture of two men’s sperm cells because the equipment was not properly cleaned after its last use, she may become pregnant with fraternal twins who have different biological fathers. Again, while possible, this occurrence is exceedingly rare.
Note: Identical twins cannot have different fathers. Identical twins are formed when the zygote created from one egg cell and one sperm cell splits during its development. When a single zygote produces twins, one man is the father of both children.
In paternity cases involving fraternal twins, Beta Paternity encourages both twins to be tested with the alleged father. For more information about our paternity testing service, please visit our Home Paternity Testing page.
