Does NoFap Increase Testosterone?
Written by Muneeb Rana · Medically reviewed by Safi Allah Khan · Last updated 24 October 2026
Quick answer: Does NoFap increase testosterone? Not in a lasting way, based on current evidence. A small 2003 study of 28 men found a temporary peak around day 7 of abstinence, then a return to baseline. There's no good evidence that long streaks raise testosterone. Sleep, exercise and weight matter far more.
The day-7 study
Jiang et al. (2003) measured serum testosterone in 28 men during abstinence. Levels peaked on day 7, at about 145% of baseline, then dropped back (PubMed). It was small and hasn't been widely replicated.
Other research
Studies on sexual activity and hormones are mixed and mostly short-term. Normal masturbation isn't known to lower testosterone in a harmful way.
Why claims spread
The day-7 finding gets repeated without context, and people feeling better on NoFap attribute it to hormones. Other changes, like more sleep and exercise, are more likely explanations.
What supports healthy levels
Enough sleep (CDC), regular exercise (Mayo Clinic), a healthy weight and managing stress. If you have symptoms of low testosterone, like low libido, fatigue or mood changes, see a doctor for a blood test.
