A white woman who was accidentally impregnated with an African-American’s sperm donation has lost her legal battle with the sperm bank she alleges was at fault.

An Illinois judge tossed out the lawsuit filed by Jennifer Cramblett, who was artificially inseminated with sperm from the wrong donor in 2014.

As a result Ms Cramblett gave birth to a mixed-race daughter, leading to the MidWest Sperm Bank apologising and refunding the cost of the procedure.

Ms Cramblett’s suit said the mistake caused her and her family stress, pain, suffering and medical expenses.

She said she feared her daughter would be an outcast in the predominantly white community where her family lives.

However DuPage County judge Ronald Sutter threw out the lawsuit, agreeing that the case lacked legal merit.

The lawsuit also claimed that Ms Cramblett was unprepared to raise an African-American child, according to The Washington Post.

“Getting a young daughter’s hair cut is not particularly stressful for most mothers,” the lawsuit said. “But to Jennifer it is not a routine matter, because Payton has hair typical of an African-American girl.

“To get a decent cut, Jennifer must travel to a black neighbourhood, far from where she lives, where she is obviously different in appearance, and not overtly welcome.”

The mix-up meant that when the couple chose sperm from donor no.380, they were given sperm from donor no.330 instead.

The suit alleges the paper record system led to an employee misreading the number.

“Jennifer’s stress and anxiety intensify when she envisions Payton entering an all-white school,” the lawsuit said.

“Ironically, Jennifer and Amanda moved to Uniontown from racially diverse Akron, because the schools were better and to be closer to family.

“Jennifer is well aware of the child psychology research and literature correlating intolerance and racism with reduced academic and psychological well-being of bi-racial children.”

She sought at least $50,000 in damages.
