I know it has many side effects. My girfriend suffered many of them when she was taking the pill and I had to beg her to stop because it just was not worth it.
And fuck off of course it's easier to stop ovulation than sperm production. It's a numbers game. Also not like I fucking made hormonal birth control. What we have now is bad and you can go ahead and find a better alternative with less side effects. That does not mean the new birth control should also have side effects. Take issue with the people that approved the current ones.
