Male 'contraceptives': "The pills appeared to lower testosterone levels without adverse side effects"
(interestingengineering.com)https://interestingengineering.com/male-contraceptive-pills-birth-controlspoiler: If your T levels are so low that you are shooting blanks, there will be massive side effects. Literally every doctor on the planet should be able to tell you this. If your T levels are that low you could probably compete in women's sports as a MtF tranny.
"No adverse side effects" Is a dirty lie and they know it. Even a layman should be able to see this but sadly most are just sheep who will take the pill so they can do the nasty with out a rubber.
