FAQ: NoFap - if I stop masturbating will it increase my testosterone levels?

In 2002, a study (full text available in pdf on top right of link) of 28 men was done on the relationship between masturbation and testosterone levels. The study showed that after 7 days of abstinence, there was a single day 46% increase in serum testosterone levels, and then a drop back to baseline on day 8. If you spread that out over the week, it averages to ~6% daily increase.

Is this a significant increase?

Should I do NoFap to increase my testosterone levels? What if I time it to fap exactly once every 8 days for optimal testosterone levels?

What's this I hear about androgen receptors? Are there any scientific studies that show NoFap has an effect on androgen receptors?
