Say if they use depo provera injections as the long term contraceptive it could very well reduce their willingness to do it. And help with [painful] periods btw.
Well, more accurately speaking it should reduce/get rid of [testosterone]-induced libidinal impulses. Of course some inherent preference, cultural compulsion and your partner[s] are big factors too (I'm guessing haha). But yea, I'm willing to bet some money that if used for over a year it would significantly reduce sexual behavior in the treated population. Which also makes me surprised why pro-abstinence people are often opposed to such methods.
