A male contraceptive capsule will finally be produced, however it should overcome “the angle of males”, the American biologist Gregory Pincus mentioned. Pincus, the “father of the capsule” for ladies, made that prediction when visiting Sydney – in 1964.
The capsule had arrived in Australia simply three years earlier, bringing the sexual revolution with it. Since then, the hormonal stage and blend has been improved and long-acting contraceptives corresponding to implants and intrauterine units have added to girls’s choices.
However 60 years after Pincus’s pronouncement, vasectomies and condoms stay the one contraceptive choices for males – leaving girls with the monetary burden, the psychological load and the unwanted effects of stopping undesirable pregnancies.
Over that point, promising merchandise have popped up, however, regardless of common headlines claiming a capsule is simply across the nook, none has made it to market.
Some have blamed double requirements and sexism in drugs. Trials have been cancelled due to unwanted effects which can be just like these girls put up with, together with temper adjustments, pimples and decreased libido.
By 1964, Pincus had been experimenting with sperm-stopping drugs for six years.
“One of many greatest issues standing in the best way of scientists is the angle of males usually,” he mentioned. “Many feared a contraceptive capsule would intrude with their intercourse drive. [That] can’t be thought of acceptable.”
‘It’s just like the IUD, for males’
Whereas gendered hurdles stay, some assume attitudes are lastly shifting. And there are (once more) promising hormonal and non-hormonal merchandise on the horizon.
Louise Keogh, a well being sociology professor on the Melbourne College of Inhabitants and International Well being, says she is cynical however nonetheless hopeful that at some point males can have entry to reversible contraception.
“Each 5 years there’s a brand new drug, it really works, it stops the manufacturing of sperm or there’s one other mechanism,” she says.
“The sample appears to be they get to trial, then there are reported unwanted effects and a ‘delayed return of fertility’, then they offer up on it.
“The unwanted effects are sometimes similar to what’s reported for ladies. Temper swings, weight acquire, pimples … I don’t perceive why a delayed return of fertility can be a dealbreaker.
“So I’m very cynical after I hear of a brand new trial as a result of I’ve heard it so many instances earlier than.”
In 2016, the trial of an injection that lowered sperm counts to stop 96% of pregnancies was aborted due to too many unwanted effects. Some males suffered pimples, weight acquire or temper swings.
There have been extra severe issues – one man developed extreme melancholy and one other turned suicidal (the feminine contraceptive capsule may also trigger melancholy) – however different trials have been stopped as a result of males discovered the unwanted effects of protected and efficient remedies “unacceptable”.
That may very well be one purpose the pharmaceutical trade has traditionally proven a “lack of curiosity” Keogh says, although research have proven sufficient males would have an interest to make a contraceptive commercially viable.
Contenders embody methods to suppress sperm manufacturing, motility (the flexibility for sperm to maneuver effectively) or means to fertilise an egg, and methods to cease the sperm from leaving the vas deferens.
Researchers have examined testosterone and progestin, a “swap” that stuns sperm, and a polymer that blocks tubes.
Dundee College researchers have been engaged on a variety of choices, with assist from Invoice and Melinda Gates Basis grants. They’ve examined hundreds of already accepted medication and say they’ve discovered efficient methods to “halt the sperm in its tracks”.
The biotech firm Contraline is trialling an injectable non-hormonal hydrogel that blocks the trail of sperm. “It’s just like the IUD, for males,” the corporate says.

The US National Institute of Child Health and Human Development is conducting clinical trials, including of a hormonal gel that men rub into their shoulders to reduce sperm production. The National Institutes of Health have tested a compound on mice that stops sperm being able to move.
Societal changes
The medical director of Family Planning Australia (FPA), Dr Clare Boerma, says there have been “big shifts” in attitudes among men and in society generally. Traditionally contraception was seen as women’s responsibility, particularly within relationships, so women bore the side effects and the cost.
But the number of vasectomies is on the rise. FPA’s service is booming and it now has a waiting list, Boerma says.
Medicare statistics compiled by Vasectomy Australia show a 75% increase over the decade to 2022-23 from 22,213 in 2013-14 to 38,875.
“We do hear from both men and women there’s a desire for more options for men … some men find the idea of a vasectomy terrifying,” Boerma says.
“Societal attitudes are shifting and there’s probably more demand for it now. The more options the better.”
Last year a Senate inquiry into universal access to reproductive healthcare found male contraceptives were “an effective method to prevent pregnancy”. It noted that women disproportionately bore responsibility for contraception.
“This results in women commonly carrying greater financial costs as well as incurring any associated health burdens that may result, such as common negative physical side effects and the consequences of contraceptive failure,” it found.
The government is currently considering the report.
“All too often the burden of, and responsibility for contraception falls solely on women,” the assistant health and aged care minister, Ged Kearney, says. “It’s important that both men and women have a range of contraceptive options available to them.”
Boerma says when and if a male pill is finally available, it will spark a range of new questions and conversations around responsibility, trust and consent.
“And the motivations for someone to put up with side effects … the question has been whether the motivators would be different and whether women would trust partners [to keep taking the contraceptive],” she says.
“It’s a brand new area – growing a drug to stop a situation in one other particular person.”
