新泽西州帕塞伊克县发生了一起奇案，一对双胞胎女婴竟然有两个父亲。据法院判决，法庭文件中与孩子母亲同居称为 “A.S.”的男子只需要支付一个孩子的抚养费，另一负责任男子付另一份。
　　帕塞伊克县高等法院法官Sohail Mohammed做出裁决，这对双胞胎的母亲“T.M.”在与A.S.发生性行为的一周内，又与另一名未公布身份的男子也发生了性关系，导致她怀上的双胞胎罕见地有两个父亲。
　　专家证实，在同一个受孕周期内，两个卵子可以接受不同的精子。根据1997年发表的一个学术研究，每1.3万个亲子鉴定结果中，才有一起这样的情况。

1 womb, 2 dads: Judge rules man must only support one twin

The man who was believed to have fathered twin girls in Passaic County actually only fathered one of them, according to a precedent-setting ruling by a Superior Court judge.

It's the first paternity case in New Jersey and only the third nationwide to feature two different fathers for a set of twins.

Judge Sohail Mohammed ruled that a man identified only as "A.S." was off the hook for child support payments to one of the twins after DNA testing determined he fathered one with 99.9 percent certainty but could not have been the father of the other.

The mother, identified only as "T.M." gave birth to twin girls in January of 2013 and named A.S., a romantic partner, as the father of both kids when applying for public assistance. But after she admitted that she had sex with another, unidentified man within a week of having had sex with A.S., social services ordered a DNA test. In November of 2014, the tests came back. And they were surprising.

Dr. Karl-Hanz Wurzinger, a DNA expert, testified that the two eggs were fertilized from different fathers during the same menstrual cycle.

An academic study he published in 1997 found that different fathers occurs in about one out of every 13,000 reported paternity cases involving twins, according to the court case.

"A.S.," who represented himself in court, will pay $28 a week in child support payments to his offspring.

Liana Allen, who represented the Passaic County Social Services Board in the case, could not be reached for comment.
