The New Jersey Fertility Clinic has been ordered to reveal the list of sperm donors after a baby mix

A New Jersey fertility clinic has to hand in a list of sperm donors after a white couple said that the facility had improperly impregnated a woman with the sperm of an unknown Asian man.

The couple said they went to the Institute of Reproductive Medicine and Science at St. Barnabas Medical Center in Garden State after being prevented from getting pregnant. By opting for artificial insemination through in vitro fertilization, they had a successful little girl. But when the child was about two years old, the couple noticed that their child was developing "Asian traits," according to his lawyer, Dave Mazie.

Mazie told NBC News that the couple, who asked to remain anonymous, performed a DNA test that revealed that the father did not share any biological traits with his child and that the father was of Asian descent. The news has devastated the couple, who have since divorced, citing the stress caused by confusion in fertility clinics, Mazie said.

The couple is now seeking damages, claiming that while they were very fond of their child, the so-called error of the clinic had caused them "great pain, suffering, permanent injury and disability, as well as loss of enjoyment of the quality of life ".

The couple, who spent $ 500,000 on fertility treatment, also wants to know who is the biological father of their child. At the end of August, according to a first report published by NJ.com, a judge said the fertility clinic had to hand over the donor list. Mazie says it's the first step to learning more about the child's biological father.

"The child has the right to know what is his genetic makeup and if there are problems," said Mazie.

Parents are open to the presence of the biological father in their child's life, but they must first know who the father is. Mazie said the father wanted to know if his sperm had ever been used during the pregnancy of someone else.

The fertility clinic did not respond to NBC News's request for comment.

"I do not think the clinic should be shut down, people make mistakes," said Mazie, "but that should never happen."
