Previous research has shown zero risk for heterosexual couples of passing on the virus, when one person is taking HIV treatment, prompting UNAIDS to launch its undetectable = untransmittable campaign.

Dr Ford Hickson, from the London School of Hygiene and Tropical Medicine, said the study confirmed that if people suppress their HIV with antiretroviral therapy, they "cannot pass their virus to other people during sex, whatever kind of sex they have".

In the study, the men with HIV had been taking antiretroviral therapy for an average of four years before it began, making the virus undetectable - defined as fewer than 200 copies per ml of blood.

Most people reach this level after taking daily HIV treatment for six months.

In the UK, 98% of people diagnosed with HIV are receiving treatment - and 97% of those have an undetectable level of the virus - meaning they are unable to pass on the infection.
