According to media reports Friday, a paternity case involving a set of twins had twist ending, even Maury would blink at.
The girls have different dads.
A judge ruled Monday in a paternity case that the man from whom the twins’ mother sought child support has to pay for only one of the children. A DNA test showed that he was almost certainly the father of one twin, but wasn’t the father of the other.
In court testimony, the mother said she had sex with both men in a span of about a week.
It’s rare for a woman to give birth to twins with different fathers, but can happen naturally. The phenomenon, called heteropaternal superfecundation, can occur when a woman produces two eggs during her fertility cycle instead of one, and they can become fertilized and implant within a few days of the same cycle.
“The sperm live in the genital tract for two days,” Dr. Brooke Rossi told ABC News. “It’s possible a woman can have sex with a man on a Tuesday and have sex with a different man on Wednesday, and it is possible for [her] to get pregnant,” with twins.
According to DNA expert Dr Karl-Hanz Wurzinger, the incidence of twins with different fathers occurred in about one in every 13,000 paternity cases involving twins, reports USA Today.
The judge ruled that the man owes $28 per week for only one of the children.
The incidence of twins with different fathers occurs in about one in every 13,000 paternity cases involving twins, according to a 1997 medical journal cited in the court ruling. Passaic County Superior Court Judge Sohail Mohammed wrote in his opinion that he found two other court cases nationally on such matters.
Typically during ovulation only one ovum is released to be fertilized by one sperm. However, sometimes a woman’s ovaries release two ova. Each must be fertilized by a separate sperm cell. If she has intercourse with two different men, the two ova can be fertilized by sperm from different sexual partners. The term for this event is heteropaternal superfecundation (HS): twins who have the same mother, but two different fathers.
In May 2009, Mia Washington from Texas also gave birth to twins with different fathers.
She and her fiancé ordered a paternity test when they noticed the twins had very different features. She then admitted to having an affair.
