I agree many modern doctors are divided on this topic, but many who speak against semeb retention, have themselves never experienced the deep, lasting & even spiritual benefits of it. The benefits which I saw after no seminal discharge & nightfall for close to 6 months : 1. Rock solid elections 2. Anxiety & depression almost disappeared 3. OCD thoughts/sticky thoughts became less powerful or non existent 4. A wave of general happiness throughout the day 5. Ability to walk, run & exercise almost 3x times of what I previously could do 6. Deep & restful sleep 7. Glowing eyes & skin 8. Liking one's own company to work on deep projects close to the heart 9. Negligible social anxiety 10. Fearlessness 11. No incidence of cough/cold/sickness during the period of retention 12. Scalp hair getting shinier & healthier plus beard hair getting fuller and denser
