Can we reverse the damage done?

I have been practicing semen retention for about 2 years, but I relapsed couple of times.

This time I feel very different though. I have been going strong for two months. I have changed my diet to animals based with lots of fatty meat, eggs and butter. I am not even entertaining lustful thoughts and edging and I disregard anything sexual. Screen time reduced, more books read, an instrument is practiced, positive mindset is almost always present.

All withdrawal symptoms like anger, anxiety and mood swings aside, I have never felt healthier and more content with my life.

One thing I wonder just like the title says, when we retain for long periods, can we reverse some of the damage we did due to our years long excessive generative loss? Or we just halt the process and slow the aging down to an extent?

Wish the best for all.
