While this idea has yet to win over health regulators and companies, it may be catching on more quickly among the general population. In France, a new male birth control product has been making headlines in recent months: a thermal ring called Andro-Switch designed to bring the testes closer to the body to naturally raise their temperature.
The pitch: if worn at least 15 hours a day for a few months, it lowers sperm production enough to cause temporary and reversible infertility. In the US alone, 77 per cent of sexually active men aged 18 to 44 surveyed in were "very or somewhat" interested in trying out a male form of birth control other than condoms or vasectomy.

Recent research suggests a clear majority of men believe birth control should be a shared responsibility. A few decades ago, people were simply grateful there were contraceptive methods. Richard Anderson. Temporarily blocking this effect without lowering hormone levels to such an extent that it creates side-effects is the issue. But this latest male pill, being tested by researchers from LA BioMed and the University of Washington, should hopefully achieve this goal, researchers say.
Initial "phase one" safety tests with 40 men looked promising, they told the Endocrine meeting in New Orleans. And among those taking the androgen-based drug, levels of hormones required for sperm production dropped greatly compared with placebo, returning to normal after the trial. Five men on the pill reported mildly decreased sex drive - and two described mild erectile dysfunction - but sexual activity was not decreased, no participant stopped taking it because of side-effects and all passed safety tests.
The researchers behind the work, Prof Christina Wang and colleagues, are excited but cautious about the findings. But bigger, longer trials were needed to check it would work well enough as a birth control.
And this is not the only prototype hormone-based male contraceptive Prof Wang has been testing. She and colleagues have come up with a body gel men in the UK will be trying as part of an international trial.
Users apply it daily to their back and shoulders, where it can be absorbed through the skin. Progestin hormone in the gel blocks natural testosterone production in the testicles, reducing sperm production to low or nonexistent levels, while replacement testosterone in the gel maintains sex drive and other functions that rely on the hormone.
And trials in men have suggested this is safe enough to move into the next phase of testing. Other scientists have been trying delivering longer-acting birth control hormones in a jab given every other month. But they stopped enrolling men to their phase-two study , looking at the safety and effectiveness of the injection, after some of the volunteers reported side-effects, including mood disorders or depression.
For men who don't fancy taking hormones, researchers have been looking at ways to block sperm flow, stopping it from ever leaving the penis - effectively, a non-surgical vasectomy. Many men express a desire to share this responsibility equally with their female partners. Even so, the gap in options is large.
Science has tried to fill the void, but multiple research studies have started and stopped over the course of many years. Condoms are a type of barrier birth control. To prevent pregnancy, a condom is placed onto an erect penis and worn during vaginal intercourse. Condoms are usually made from latex or polyurethane.
They may also be made from lamb membrane called lambskin. Condoms come in various sizes and textures. Some are lubricated to make penetration easier and reduce friction, which can cause a condom to tear. Others are coated with spermicide for added protection against pregnancy.
Vasectomy, also known as male sterilization, is a surgical procedure designed to be permanent birth control. During a vasectomy, your surgeon will divide and close off the ends of the tubes that transport sperm the vas deferens. Since this stops sperm from entering seminal fluid, your ejaculate will not be able to inseminate your partner. Conventional vasectomies are outpatient procedures.
Recovery from a vasectomy usually takes about a week. During that time, you should avoid sexual activity and physical activities such as heavy lifting. Many insurance plans, including Medicaid, cover the cost of vasectomy.
