Newer birth control for men is beginning to fill the gap between the traditional condoms and sterilization.

One new technology involves inserting a hypodermic needle into the scrotum. It is said to decrease libido.

For men, contraception had remained fairly stagnant for the past century, primarily limited to condoms (85 percent effective when used correctly) and vasectomy, which is usually permanent. New methods are trying to move beyond centuries-old contraception applications, and some younger men say they are enthusiastic about the prospects.

But they want them to be safe.

“Contraceptives are necessary regardless of which partner is using them,” said Shane Sullivan, a senior at Colgate University in New York. But, “I’m adverse to solutions that may induce side effects.”

But as with contraception for women, methods free of side effects are hard to come by.

Nestorone-Testosterone is a hormonal birth control gel for men that’s been in the making for more than a decade. The gel is applied to the arms and shoulders every day and works to shut down hormones responsible for sperm production. But because it drops testosterone levels, reported side effects include a low libido or problems with ejaculation.

Meanwhile, scientists at the National Institutes of Health in Bethesda, Maryland have developed a daily birth control pill called DMAU. It lowers testosterone and sperm production, which decreases the likelihood of pregnancy, according to a study by the University of Washington Medical Center and at Harbor-UCLA Medical Center in Torrance, California.

All participants who tried DMAU noted some weight gain and a decrease of high-density lipoproteins (HDL, “good” cholesterol responsible for healthy cardiovascular functioning).

“Despite having low levels of circulating testosterone, very few subjects reported symptoms consistent with testosterone deficiency or excess,” said the study’s senior investigator, professor of medicine Stephanie Page at the University of Washington in Seattle.

“DMAU is a major step forward in the development of a once-daily ‘male pill,’” Page said. “Many men say they would prefer a daily pill as a reversible contraceptive, rather than long-acting injections or topical gels, which are also in development.”
