67-year-old Prince Frederic von Anhalt visited a fertility clinic in Beverly Hills on Wednesday and said in a phone interview with KTLA, that "we wanted to do this 25 years ago when we first got married."
According to Anhalt, his 94-year-old wife has always dreamed of having a child with him -- preferably a boy -- to carry on the Gabor name, because "when she goes, the whole family will be gone."
"It would be great if she could stay alive for the next few years. She always wanted a little polo player... we both used to play polo."
Gabor's two sisters did not leave an heir and her only child -- 64-year-old Francesca Hilton, a product of Gabor's second marriage to hotel magnate Conrad Hilton -- does not use the Gabor name.
According to Anhalt, "she wants nothing to do with the family."
Hilton's full name is Constance Francesca Gabor Hilton.
When Hilton heard the news about the baby, she described herself as shocked and told CNN "That's just weird."
Gabor has suffered major health problems this year. In recent months, she had her hip replaced and her leg amputated. She has been unable to walk since a 2002 car accident.
Anhalt said, "When my wife had the operation, when her leg was amputed, she said to me remember we always wanted to have a baby? And I said, it's not too late."
The prince is Gabor's ninth husband. He acquired his royal title when he was adopted as an adult by a German woman.
The Hungarian-born actress is famous for her many marriages and outspoken personality.
She is best known for her roles in John Huston's Toulouse-Lautrec biopic, "Moulin Rouge," in 1953, "The Story of Three Loves" in 1953, and Orson Welles' 1958 cult classic, "Touch of Evil."
