A Dutch fertility doctor accused of using his own sperm to inseminate patients without their consent has been confirmed as the father of 49 children.

DNA tests revealed that Jan Karbaat, who died two years ago, impregnated their mothers at his clinic in Bijdorp, near Rotterdam.

The results were confirmed on Friday after judges allowed their release.

One of the children, named Joey, said he could “finally close the chapter” now he knew Mr Karbaat was his father.

“After a search of 11 years I can continue my life. I am glad that I finally have clarity,” he told Dutch broadcaster NOS.
