Birth Control Shot: Gel Injection Into Male Reproductive System Stops Pregnancy

Just months after the trial of a hormonal birth control injection for men was
halted when some complained of side effects, there is new hope of a way to b\
lock sperm — and thus pregnancy — without a condom.

Researchers have reported that a gel injection completely prevented pregnancy
among monkeys, opening the door for human trials. The Parsemus Foundation said in a statement about the work that the results confirm findings of previous tests on rabbits, that the Vasalgel blocks the passage of sperm from the testicles into the penis when injected into their connecting tube called the vas
deferens.

The related study in Basic and Clinical Andrology describes the way the con\
traceptive works as filling up the passageway to the penis. It “acts as a mechanical barrier to the passage of sperm.” And if the male using the birth control method reverses direction and wants to have children, the gel could be flushed out.

The Vasalgel “could be the first long-acting, non-hormonal, potentially rever
sible male contraceptive to reach market,” according to the foundation.

For the men who experienced side effects while taking hormonal birth control, the study says with the Vasalgel the side effects were comparable to what men may experience after a vasectomy. “The presence of Vasalgel appears to be well-tolerated and placement resulted in minimal complications.”

The monkey trials were proof that the gel could work on large animals that are
“anatomically similar to humans,” the Parsemus Foundation said, and now the
researchers are preparing for human trials. If they are successful, men could
have a method of birth control other than condoms, vasectomies, and “pulling
out.”

“The demand for new male contraceptive methods is growing,” the organization
said. “Surveys indicate that the majority of men would be interested in usin
g a new contraceptive, and about 20 percent of couples already rely on existin
g male methods for reproductive control.”
