This is the Guardian.

When the contraceptive pill was introduced in the 1960s, it promised a new era of freedom for women.

It allowed women to sever the tie between sexuality and reproduction so that they could control their

reproduction without their partners knowledge or participation.

But six decades on that control can seem more like a burden.

Women are still largely responsible for contraception and all the admin and side effects that can

come with it.

For men, there remain only two choices. Condoms or

vasectomies. It's also reducing men's autonomy because men don't have any good options

and we are going to hold you

socially and financially responsible

for any unintended pregnancies.

And in some ways that feels unfair to men

because we're not equipping them with the tools to prevent

unintended pregnancy.

But that could finally be about to change.

At the end of last year a new male birth control pill entered human trials here in the UK and there are several other serious contenders making their way down the pipeline.

I do think we can genuinely say hand on heart they were looking at good progress at the moment.

So today we're asking what's been holding male contraceptives back all these years and if we had a male pill

would men want to use it. I'm the Guardian Science Editor Ian Sample and this is
