The pelvic floor muscles (pubococcygeus, PC muscles) are directly involved in the ejaculation reflex in men — strengthening them is a clinically proven method for improving control.
How to find the right muscle Stopping the flow of urine is exactly the muscle you need to train. This is just a familiarization exercise, not a regular practice method.
Exercise regimen Contraction of the muscle for 3-5 seconds, then relaxation for the same time — 10-15 repetitions, 3 times a day. Gradually increase the duration of the contraction to 10 seconds.
Clinical Evidence A 2014 study (involving men with premature ejaculation) showed that after 12 weeks of PC training, most participants experienced significant improvements in control.
Expected results over time Like any muscle training, results are not immediate — at least 4-6 weeks of regular practice are required for noticeable changes.
