HONG KONG • To take the risk of pregnancy at age 50, Andy Lau's wife Carol Choo tried both Eastern and Western medicine, said Apple Daily.

She is reported to be expecting the couple's second child, a happy development in a quest that began two years ago, said the newspaper yesterday.

That was when she returned to well-known gynaecologist William So, who delivered the couple's daughter, Hanna, and started receiving artificial insemination, said the report.

She also saw alternative therapist Chan Tai, who used moxibustion - burning mugwort on or close to the skin - to treat her "cold uterus". In traditional Chinese medicine, a cold uterus may result in endometriosis, miscarriage and infertility, said the daily.

An unnamed source was quoted as saying: "Andy Lau and his wife both had moxibustion. Andy Lau's was mostly on the back. His wife had moxibustion because she had a cold uterus."

The source said Choo kept having moxibustion before she became pregnant with Hanna and returned to the therapist last year "probably because she wanted to have a baby again".

Choo, who will be 50 next month, and Lau, 54, wed in the United States in 2008.

In 2009, after the marriage was reported by Apple Daily, he said they had tied the knot to be eligible for fertility treatment in Hong Kong.

Hanna will be four in May.
