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.

100% this.
I know of a few people that this happened to…make sure you are testing 0% sperm count before going “hats off”
Oh absolutely. These kids gonna eat me out of house and home. I ain’t trusting it until after I’ve been given the all clear and still pulling out just in case
Even if it’s zero percent at the test, does that mean all future ejaculations will be 0%?
