The new contraceptive – NES / T & # 39; is a gel that men rub on arms and shoulders

A new contraceptive is being tested, according to which men would apply a gel on their arms and shoulders.

Scientists are looking for couples in Edinburgh and Manchester to participate in an innovative study.

Called NES / T, it inhibits sperm production in men when it is used daily, the product being applied to the arm and shoulders.

As many women may experience unpleasant side effects with traditional contraceptives such as the pill, the researchers sought alternatives.

The gel was developed as part of an international project funded by the US National Institutes of Health and led by the Los Angeles Biomedical Research Institute and the School of Medicine at the University of Washington .

In the UK, the work is done by the Saint Mary's Hospital, which is part of the NHS Foundation Trust of the University of Manchester, and by the University of Edinburgh.

Professor Richard Anderson, of the MRC's Center for Reproductive Health Research at the University of Edinburgh, said: "Previous trials have shown that hormonal contraception for men can be safe and effective.

"This test allows men to self-administer a gel, which can be much more convenient and acceptable than needing repeated injections, as was the case when they were given a freeze. previous tests. "

Cheryl Fitzgerald, a consultant in gynecology at Saint Mary's Hospital, who is leading the study in Manchester, said: "Currently, contraceptive options for men are limited to condoms and vasectomies. preparation will allow men to control their fertility in a simple way. "

Men between the ages of 18 and 50 who have a stable relationship with a woman between the ages of 18 and 34 are invited to join the trial by calling 0161 276 3296 (Manchester) or 0131 242 2669 (Edinburgh).

The two-year trial will require them to use the gel as the only method of birth control, with men attending these visits being organized in monthly clinics to monitor sperm production.
