Secret 'lunch hour breaks', where women can get themselves sterilization appointments are becoming popular.
A private clinic claims it is the first in the country to offer a "walk in - walk out" ten minute procedure which permanently renders a woman infertile, without leaving any scars.
"Women can elect to have the quick and painless procedure when it suits them - and their partner won't be able to tell," the Telegraph quoted Cadogan Clinic in Knightsbridge as saying in a promotional ad.
Consultant gynaecologist Martin Farrugia, who works for the clinic, said it was a solution for those who didn't want to tell their partners that they did not want any children, or that they felt their family was complete. Others lived "complicated lives" with multiple lovers, which meant they did not want to risk becoming pregnant.
"There are many reasons why a woman might choose to have this treatment here; privacy is certainly one of the advantages of the procedure - there are no scars, so women can take control over the decision," he said.
The operation, called Essure, involves inserting two tiny metal coils through the vagina with the aid of a hysteroscope into both Fallopian tubes. In three months, the tissue around it grows, blocking the tubes entirely. Essure takes ten minutes, involves no incision or stitches, and requires just 45 minutes recovery, so women can go straight back to work, after having the 2,700 pounds operation in their lunch hour, the clinic says.
