An injection for men appears to be just as effective at preventing pregnancy as the birth control pill, finds new research that could revolutionize contraception.

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

The contraceptive is a form of testosterone that is injected into the buttocks once a month. It works by temporarily blocking sperm production.

Chinese researchers injected 1,045 healthy Chinese men aged 20 to 45 years with a 500 mg of testosterone undecanoate in oil, once a month for 24 months. All of the study participants had had at least one child and all their female partners, aged 18 and 38 years, also had normal reproductive function.

They found the contraceptive was almost 99 per cent effective, with a failure rate of only 1.1 per 100 men. Continue reading

Scientists in the United States have successfully tested the new technique – which involves tiny objects called nanoparticles – on rats and believe it could also be used to help humans.

Under the therapy, nanoparticles that release the anti-erectile chemical nitric oxide are rubbed on the problem area, and absorbed directly into the skin.

Of the seven rats treated by the Albert Einstein College of Medicine in New York, five showed signs of arousal, according to results presented to the American Urological Association (AUA).

The new treatment would likely have fewer side effects than Viagra, which is taken orally and been shown to cause headaches and facial flushing.

Researchers also believe that the nanoparticle therapy could work much more quickly than Pfizer’s market-leading drug, which takes up to an hour to kick in.

“This is a very interesting concept which has potential to impact treatment of many conditions including erectile dysfunction if it can be translated from the animal lab to clinical practice,” said Ira D Sharlip of the AUA.

An estimated 2.3 million men in Britain are thought to suffer from the erectile problems, which can be caused by a variety of conditions.
