Woah, now. You are dangerously mistaken here. As I wrote over in: https://news.ycombinator.com/item?id=43746406 https://news.ycombinator.com/item?id=43746406 I’m on TRT, without hCG. I went and had a vasectomy a year ago. Because I’m weird and infinitely curious, two or three days after the procedure, I took three samples per day, and looked at each under the microscope. What I saw put to shame just about any video I could find online of a “good” sperm sample. Straight laser beams, zipping from one side of the slide to the other. If you were to scale Micheal Phelps down to these swimmers, he’d stand no chance. And the concentration was ridiculous, too. And this all 2-5 day old (at least) sperm! TRT is not a reliable form of birth control.
