QUICK ANSWER
No. Masturbation does not lower your testosterone in any lasting way. Levels rise briefly around orgasm, then settle back to normal within minutes. The viral claim that a week of abstinence spikes testosterone comes from a study that was later retracted. Only a blood test shows your real level.
Check your testosterone with the right test →As of July 2026.“Does masturbation lower testosterone?” is one of the most searched men’s health questions online. This guide sticks to what the studies actually found, and to what a blood test can and cannot tell you.
You have read that masturbation drains you. That it tanks your testosterone, saps your drive, or that quitting for a week will make you feel like a new man. It is a fair worry. It is also, on the evidence, mostly a myth.
1. Does masturbation lower testosterone?
No. Masturbation has no lasting effect on your testosterone. The research is limited, but it points one way. Your testosterone does move around sex, yet only for a few minutes.
One study measured hormones through the act itself. Testosterone rose from arousal to orgasm, then fell back to its starting point about ten minutes later. That is a blip, not a shift. A separate study followed ten men through three weeks without orgasm and found no meaningful change in their baseline levels.
So whether you masturbate daily or not at all, your baseline testosterone stays roughly the same. A medically reviewed summary of the research puts it plainly: masturbation does not seem to have any long-lasting effect on testosterone levels.
The bigger point is this. If you feel flat, low on drive or tired, those symptoms are worth taking seriously, but they are non-specific. The NHS makes the same point about male hormone symptoms in general.
“In many cases the symptoms are nothing to do with hormones.”
— NHS, The ‘male menopause’
In other words, do not blame your habits and stop there. If the worry is real, measure the hormone instead of guessing at it.
2. Where did the “no-fap raises testosterone” claim come from?
You have probably seen the number: skip ejaculation for seven days and your testosterone jumps by about 45 percent. It sounds precise. It is also built on shaky ground.
That figure traces to a single 2003 study of 28 men. It reported that testosterone peaked at 145.7 percent of baseline on day seven of abstinence. That is where the “45 percent” online claim began.
There are two problems. First, the journal later retracted the paper, because it overlapped heavily with an earlier article by the same author. A retracted study is not evidence. Second, even at face value, it described a brief peak on one day, not a higher baseline you get to keep.
The fact-checking site Snopes traced the viral claim back to that same retracted study. So “semen retention” and no-fap streaks will not raise your long-term testosterone. If you want a real number, you have to test for it.
3. What actually changes your testosterone?
If you want to protect your testosterone, forget about masturbation and focus on the things that genuinely move it:
- Sleep. Most of your daily testosterone is made while you sleep. Short, broken nights lower it, as our sleep and testosterone guide explains.
- Body fat. Carrying extra weight, especially around the middle, is one of the strongest drivers of low levels. See belly fat and testosterone.
- Alcohol. Heavy or regular drinking suppresses testosterone. Our guide on whether alcohol lowers testosterone covers how much is too much.
- Age. Levels drift down slowly from your late thirties, as our testosterone levels by age chart shows.
- Stress. Long spells of stress raise cortisol, which works against testosterone.
These are the levers that matter. Our guide on how to increase testosterone naturally walks through the habits that help, and the ones that do nothing.
4. How do you check your real testosterone level?
You cannot feel a testosterone level. Symptoms like low drive, low mood or tiredness are real, but they overlap with many other things. The only way to know your number is a blood test. The markers worth reading together are:
- Total and free testosterone. The hormone itself, plus the active fraction your cells can actually use.
- SHBG. The protein that binds testosterone and sets how much is free to work.
- LH and FSH. The brain signals that show whether a low reading starts in the testes or higher up.
Timing matters. Test in the morning, ideally before 10am, because levels are highest then and drift down through the day. Our guide to the best time to test testosterone covers the rules.
These markers sit in Helvy’s Complete Male Hormones panel (£119). Testosterone and SHBG also appear in the Hormone Balance panel (£99). To check the mix that fits your symptoms, the build-my-test tool matches you to the right markers. All are home finger-prick tests, with results in about five working days from UKAS-accredited UK laboratories.

Swap the myth for a number
Helvy’s home blood tests read testosterone alongside the other markers that shape male hormone balance, with clear, plain-English context. So you can stop worrying about habits that do not matter, and see what your levels are really doing. Results in about 5 working days from UKAS-accredited UK laboratories.
Frequently asked questions
Does masturbation lower testosterone?
No. The research shows testosterone rises briefly around orgasm and returns to normal within minutes, with no lasting change to your baseline. Medically reviewed summaries agree there is no long-term effect. This is general information, not medical advice.
Does not ejaculating for 7 days raise testosterone?
Not in any lasting way. The viral “day 7 spike” claim comes from a 2003 study that the journal later retracted, and even that described only a brief one-day peak, not a higher baseline. Semen retention will not raise your long-term testosterone.
What actually lowers testosterone?
Poor sleep, excess body fat, heavy drinking, chronic stress and age are the main drivers. These matter far more than how often you masturbate. The habits that raise testosterone naturally are the mirror image of that list.
How do I check my testosterone level?
A morning blood test that reads total and free testosterone, SHBG, LH and FSH together gives the clearest picture. The build-my-test tool matches you to the right markers. If a result is abnormal or your symptoms are severe, speak to a qualified clinician.
