There are male birth control pills under research, but the only ones so far that have been effective have had extremely undesirable side effects. It's basic physiology...women have a finite number of eggs, and release them once a month with certain hormonal triggers so there are many options for preventing that, and there are many options for preventing sperm reaching the egg. However, the technology for chemical birth controls like this doesn't translate into viable options for men, because men produce sperm all the time by the millions and, short of finding ways to kill off all the sperm, make sure the man doesn't feel like releasing them, or removing the means of escape for the sperm, there's really nothing that can be done within our current scientific and medical expertise.
That said, if something were developed, it would obviously depend on the individual...just as with women, some men are very detail-oriented and trustworthy while others are not. However, perhaps if men also had to remember a pill every single day they would realize why many women really appreciate partner support in remembering birth control pills...it's all too easy to forget every now and then, and if it's made into something that both partners monitor then it will be much more reliable.
