A Hollywood actor is one of the most popular choices.

A sperm bank in Los Angeles is offering a celebrity lookalike donor service.

At California Cryobank, you can choose which famous man you want your baby to resemble.

Physical details of donors, such as height, eye and hair colour, are listed at all clinics but at California Cryobank, donors are filtered by the celebs they most look like.

Lookalikes available at the sperm bank include David Beckham, Leonardo DiCaprio, Prince Harry, Jon Snow, Bradley Cooper, Ashton Kutcher and Keanu Reeves.

There’s also a host of famous athletes and musicians, as well as lesser known stars.

Each vial of sperm costs $900 (approx. €773).

But who’s the top lookalike donor?

Scott Brown, vice president of communications for California Cryobank, told the Sun:

“Ben Affleck was always popular from the beginning.”

Scott said the actor’s a favourite choice due to his combination of brown hair and brown eyes, which many people like.
