Macho pill

Why has the male pill taken so long to be available, when tests and trials have all been positive on the effectiveness of the contraceptive?
The pharmaceutical companies apparently, back in the 1990s, predicted it would take around 5 years for the male population to get used to the idea (and be persuaded) that they too can contribute to the family planning, hands-on.
A hard to swallow decision?
Because men cannot really be relied upon taking tablets, an implant is being considered (predicted to be available by 2016). But in the meantime (and not for the wimps!), there will be injections of both testosterone and progestin, the latter cancelling sperm production while testosterone stops fatigue, hair loss and replaces the libido. This hormone, in the form of androgen, will have to be ministered carefully to avoid the famous female mood swings, or on the other extreme, increased macho violence.
And no, fertility will not be affected, as studies demonstrate that 3 months after stopping taking the hormones, men are at their full ‘making babies’ potential.
Guys, think about it!
