Scientists at Cornell University may be closing in on the long-sought “holy grail” of male contraception: a safe, reversible, nonhormonal method that completely halts sperm production. In a breakthrough mouse study, researchers used a compound called JQ1 to temporarily shut down meiosis—the critical process that produces sperm—without causing lasting harm. After treatment stopped, sperm production bounced back, fertility returned, and the animals produced healthy offspring.
Nah, they’d gladly prevent trans women , who they view as men, from getting gender affirming care. They would try to prevent this on the same grounds of “it’s not natural to mess with people’s hormones”
