"taking so much away from women [but leaving viagra on the will pay for prescription list]?"

SMH.  You know there's a reason why Viagra is covered down there (pun intended), right?  Actually several.  Here's two: 

One, it is used for hypertension.  In both sexes.  My understanding of the US system is that this is actually the main reason it is included at all.  
Two, governments have a vested interest in promoting birth rates.  That means more tax payers (and less importing of foreigners).  Which, if you haven't figured it out yet... is the exact same logic behind not funding abortions (ie: abortions reduce birth rates).  Kinda like the real reason religions are against homosexuality... it isn't because "gay is gross", it is because they need more people to fight wears and pay tithes.
