A male contraceptive jab could be as effective at preventing pregnancies as the female pill or condoms, work shows.

The monthly testosterone injection works by temporarily blocking sperm production and could revolutionise birth control, experts believe.

In trials in China only one man in 100 fathered a child while on the injections, the Journal of Clinical Endocrinology & Metabolism reports.

Six months after stopping the jabs the men's sperm counts returned to normal.

Family planning campaigners welcomed the news and said they hoped an injection would give couples more choice and enable men to take a greater share of the responsibility for contraception.

At the moment the onus is on the woman and men do not have that much choice

But experts said more trials were needed to check the safety of the jab.

Previous attempts to develop an effective and convenient male contraceptive have encountered problems over reliability and side effects, such as mood swings and a lowered sex drive.

Despite the injection having no serious side effects, almost a third of the 1,045 men in the two-and-a-half year trial did not complete it and no reason was given for this.
