A private UK fertility clinic is offering couples a new form of IVF treatment that lets conception occur in the womb rather than in the lab, reports BBC.

Doctors hope that making fertilisation more natural will mean healthier pregnancies.

The Complete Fertility clinic in Southampton is first in the UK to use the AneVivo device method.

It is a tiny tubular capsule that is loaded with the sperm and egg before being placed into the uterus.

Prof Nick Macklon, head of the clinic, insisted it was not a gimmick. The technique, which costs around £700 per go, has been approved by the UK's fertility watchdog, the HFEA.
