The man, who has alleged to be the biological father of Nadya Suleman's octuplets, is also willing to offer help to raise her brood of 14 children.
Speaking in an interview on ABC's Good Morning America, the man, whose identity is being kept under wraps, claimed that Suleman brought him to donate sperm at the clinic where she received in vitro fertilization. However, Suleman denied that the man was the father of her children.
Her representative, Victor Munoz, has denied the man's claims by saying that he's not the sperm donor who fathered the babies.
"The real sperm donor knows who he is. This guy is definitely not the one. It's kind of comical. Nadya's not sure why he's doing this," People magazine quoted Munoz as saying.
However, the alleged donor said that he was "shocked [and] surprised" when he came to know that Suleman had delivered octuplets on Jan. 23.
He has claimed that he dated Suleman from 1997 to 1999, and is even pushing for a paternity test.
And now, he is even willing to help Suleman raise the children because he thinks that she can't do it on her own.
"Either which way, you know, know that if she needs it I'll lend a helping hand," he said.
