Couples sought for male contraception trial

Couples in Edinburgh and Manchester are being invited to take part in trials of a new form of male contraception.

Men will be asked to use a daily gel that suppresses sperm production as their sole method of birth control as part of two-year study to assess whether the gel is effective in preventing pregnancy and whether this method is acceptable to couples.

Daily gel

The gel – called NES/T – is a hormone-based treatment that is designed to reduce sperm production without affecting libido.

Men will apply the gel daily to their upper arms and shoulders and attend monthly clinics to monitor their sperm count.

Previous trials have shown that hormonal contraception for men can be safe and effective. This trial allows men to self-administer a gel, which may be much more convenient and acceptable than needing repeated injections, as was the case with previous trials.

Birth control

Condoms and vasectomy are currently the only form of contraception available to men. Many women experience unacceptable side effects with their contraceptive method and so couples are looking for alternatives.

International study

The study is being led in the UK by Saint Mary’s Hospital, part of Manchester University NHS Foundation Trust, and the University of Edinburgh. 

It is part of an international project funded by the US National Institute of Health and led by the Los Angeles Biomedical Research Institute and the University of Washington School of Medicine.

Take part

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

Currently the contraceptive options for men are limited to condoms and vasectomies. We believe this preparation will allow men to control their fertility in a safe and simple way.
