A male birth control pill would mean that men have greater reproductive control. Currently the only form of birth control that men have available to them is condoms (or a vasectomy), and so they must rely on their female partners to use birth control and to use it properly. It's a lot of trust to put into another person.
A male birth control pill would mean more evenly shared birth control, in terms of responsibility, costs, and side effects.
Not all women are able to take hormonal contraception, so it will be great that couples have another option.
Ultimately, I think it would lead to less unwanted pregnancies (couples could use both male and female birth control if they wanted), as well as less, well, "half-wanted" pregnancies (i. e. situations where the woman gets pregnant and wants to keep it, but the man doesn't want a baby).
One possible negative affect of a male birth control pill is that it could decrease the use of condoms, which could increase the rate of STDs.
