No Nut November, or the NNN challenge, is an internet challenge in which participants try not to masturbate or ejaculate for the month of November; many also avoid porn. It is a social-media trend with informal rules, not a health programme, a treatment, or a test of character.
You have probably seen it on Reddit or in a video and wondered whether to join, or what a month without would actually do for you. This page answers that from the research, not from the memes.
This site takes its name from the challenge, but it is not a competition, a streak leaderboard, or a claim about the benefits of semen retention.
Evidence strength: early for the effects of a month of abstinence; one online survey of the challenge itself, one seven-day trial, and qualitative forum studies.
What does No Nut November mean?
The researchers who studied the trend define it as a mainstream internet challenge in which participants attempt to avoid masturbation, or ejaculation as a result of masturbation, for the month of November. Garas, Levang and Pukall. The word “nut” means ejaculation.
The phrase appeared online in 2011 and spread among men on social media from around 2017; a dedicated Reddit community grew from roughly 16,500 members in 2018 to 52,000 a year later. It is associated with the NoFap community, which encourages abstinence from porn and masturbation more generally. Wikipedia has the timeline.
The framing and the jokes are aimed at men, but there is no gatekeeper. The 2025 study describes its 435 participants and non-participants as a diverse sample, and the questions on this page apply to anyone who watches porn and wonders what a break would show them.
What are the No Nut November (NNN) rules?
There is no official rulebook. The commonly described version is abstinence from masturbation, and for many participants from sexual activity altogether, for the whole month. Wikipedia summarises the common form. Groups differ on whether partnered sex counts and on whether porn is included, even though porn is the reason a lot of people join.
Because the rules are informal, the version you follow is yours to define. The most useful decision is whether you are testing masturbation, porn, or both. They are different behaviours with different roles in your life, and a month without one does not automatically tell you anything about the other.
Why do people do No Nut November?
For some it is a joke with friends. For others it is a serious attempt to change something.
Researchers who analysed 104 abstinence journals written by men on a “rebooting” forum found that members mostly started because they believed they were addicted to porn, or blamed it for negative consequences, especially sexual difficulties. These were self-selected writers describing their own perceived problems. Fernandez, Kuss and Griffiths.
Motivation also tracks beliefs. In an online survey of 1,063 people recruited through Reddit, the wish to abstain from masturbation was associated with seeing masturbation as unhealthy, with conservatism and religiosity, with lower trust in science, and with self-rated hypersexuality. It was not associated with behavioural markers such as the maximum number of orgasms in a day. Zimmer and Imhoff. Wanting to abstain, in other words, says as much about what a person believes as about what they do.
Does No Nut November have benefits?
In the only published study of the challenge, people who had taken part in No Nut November scored higher on sexual flexibility than people who never had. That is a difference between groups at the start, not an effect of the month. Over the month itself, in this sample, measures of sexual pleasure, solitary desire, sexual function, and sexual excitation did not differ between participants and non-participants. The study was an online survey with self-selected respondents, and only 114 of the 435 completed the second questionnaire. Garas, Levang and Pukall.
The often-quoted claim that testosterone peaks on day seven of abstinence comes from a 2003 study of 28 men, retracted by the journal in 2021. A retracted paper is not evidence. The original record carries the retraction notice. We found no published replication. Nothing about energy, focus, confidence, or attractiveness has been shown to follow from a month of abstinence.
What we know: in one small survey, a month of abstinence was not associated with better or worse sexual wellbeing; the physiological claim behind the challenge rests on a retracted study.
What we do not know: what happens over longer periods, what happens in clinical samples, how women and non-binary participants fare, and whether anything changes that a questionnaire cannot measure.
Can No Nut November help with a porn problem?
It can, as an experiment, if you treat it as one.
The journal writers above found abstinence very hard, because of habit and because so many everyday cues triggered the urge to watch. Those who kept going credited a mix of their own strategies and support from other people, and they attributed a range of benefits to abstinence. The authors say prospective studies are needed before abstinence can be called an intervention. Fernandez, Kuss and Griffiths.
Withdrawal is not a given either. A randomised seven-day trial of abstinence from porn, not from masturbation, found no overall group difference in craving, mood, or withdrawal-like symptoms. Fernandez and colleagues. What a month will show you is where and when the urge arrives. If you later decide to change your porn use properly, that is the material you will need.
One thing the month cannot do is find the cause of erection problems. If erections have been unreliable, do not postpone a medical appointment until the challenge is over.
What if you break the streak?
Then you have a data point, not a verdict. Read what to do after you watched again before you decide what it means.
Be careful about turning a game into a moral test. A meta-analysis, mostly of cross-sectional studies, found that feeling one’s porn use is a problem is strongly tied to moral disapproval of one’s own use, over and above how much a person watches. Grubbs and colleagues. If a lapse on 12 November leaves you feeling like a failure, that reaction tells you something about your beliefs, not only about your behaviour.
If, on the other hand, you found that you could not stop even when you wanted to, or that the pattern is costing you time, sleep, or closeness, that is worth taking seriously whatever the calendar says. Look at control and consequences, and consider talking to someone if repeated attempts are not changing anything.
Before you start
Write down which version you are following and what you want to learn from the month. Tell one person if that makes it easier to keep going. At the end, read your own notes before you read anyone’s list of benefits.
You do not need a trend to begin. But if November is when you start paying attention, that is a fair place to start.
