I maintain my conviction that, (as I said in my initial response) while there may be many men who would welcome the opportunity to control their own reproductive futures with access to a male-administered and male-maintained contraception, there just aren’t enough of them and — on my side of the globe anyway — our societal power structures just make it unlikely to ever happen.
I suggest that you look a little deeper. Men do want another form of reversible contraception. in a study of Australian men’s attitudes toward male contraception in which 75.4% of new fathers interviewed indicated they would be willing to try a male method if it were available. I am wondering what “societal power structures” you mention are? I know the drug companies aren’t keen on male contraceptives since the costs to develop something safe to prevent millions of cells doing their thing is much harder than preventing one cell from performing its function. And since funding for men’s health is abysmal in comparison to women’s funding, I can see that as a barrier. Other than that I don’t see any “power structures” at play.
Many men certainly think so. A study by the Kaiser Family Foundation showed that 66 percent of men were willing to take a birth control pill, whereas 44 percent were up for a birth control shot and 36 percent were interested in the idea of an implant. And researchers across America agree; they’ve been working for years to develop a variety of options — gels, oral contraceptives, shots and more — for males.
If there’s a future for male birth control, it’s a long time coming, experts say. Obstacles include a long development period, financial shortages and a lack of existing regulatory guidelines. Meanwhile, the pharmaceutical industry is wary of supporting new methods of birth control for a variety of reasons — such as lawsuits and a fear of disrupting a lucrative oral contraceptive market. Scientists also say it’s more difficult to block sperm — every milliliter of semen produced has 15 to 200 million sperm in it — than it is to control the ovulation of one egg.

A cross-cultural study to assess attitudes toward hormonal male contraception interviewed a total of 1843 men in Edinburgh, Cape Town, Shanghai and Hong Kong. The majority of participants (44–83%) stated they would use a male contraceptive pill.[33] In a survey of over 9000 men aged 18–50 years from nine countries, 28.5–71.4% of various nationalities expressed willingness to use a hormonal male contraceptive, with an overall willingness rate of 55%;[44] 55–81.5% of these participants indicated that both they and their partner participate in the selection of a contraceptive method.[44] Even more positive figures were reported in a study of Australian men’s attitudes toward male contraception in which 75.4% of new fathers interviewed indicated they would be willing to try a male method if it were available.[35]
