California becomes favored center

The number of Chinese seeking surrogacy services at the Southern California Reproductive Center in Los Angeles has risen gradually in recent years, according to Mark Surrey, the center's chief medical officer.

Last year, more than 100 Chinese clients opted for the center's surrogacy services, accounting for about 50 percent of all Chinese who used the facility, Surrey told China Daily in an email exchange.

As a result of physical factors, the average age of clients for surrogacy services is 40, he wrote. In addition, about 50 percent of Chinese people undergoing the treatment were trying to have a second child.
