No Nut November and Semen Retention: Does Holding It In Really Raise Testosterone, Clear Your Skin, or Make You More Attractive?

Does going without ejaculating for a month, or for much longer, really make you better looking? That is the promise behind No Nut November, which starts November 1, and behind semen retention, its year round cousin. Fans say it gives you more testosterone, clearer skin, a deeper voice, a sharper jawline, and a strange pull on women. Here is what the research actually found, what new 2026 studies add, what men on long streaks report this month, and a blunt verdict on whether it is worth doing for your looks.

What supporters say

The claims are big, and they get bigger the longer the streak.

More testosterone. This is the core claim, and it is the one with a little real data behind it (see below).
Better skin, eyes, and hair. Long time retainers talk about a "glow," whiter eyes, faster beard growth, and less hair fall.
A deeper voice and more presence. Many say they speak with more authority and that other men treat them with more respect.
More attention from women. This is the most common claim by far, often called "magnetism" or "aura."
More drive and focus. Less brain fog, more energy for the gym, and more boldness to approach people.

It is also a big online topic. A 2022 study of men's health content found semen retention was the most viewed men's health topic on TikTok, with over 1.2 billion views on its top hashtags. It was also the least accurate topic the researchers rated, scoring 1.5 out of 5 for accuracy. Doctors made only about 1 in 10 of the posts.

What the research says about testosterone

There are only two small studies, and both are old.

The 7 day study (2002). Researchers in China checked blood testosterone every day in 28 men after they ejaculated. Levels stayed flat on days 2 to 5, then peaked on day 7 at about 146% of their starting level. After that peak, there was no steady pattern. Levels did not keep climbing.
The 3 week study (2001). A study had 10 men go without sex or masturbation for 3 weeks. Their testosterone was higher after the break. But orgasm itself did not change their hormone response.

That is the whole testosterone case. Two studies, 38 men total, no long streaks tested, and no study showing a lasting rise over 30, 60, or 100 days. A urologist quoted on Oct. 27, 2026 pointed out a catch in the 3 week study: the men knew they could finish at the end, so the bump may have come from anticipation, not from holding it in. Her view was that any rise is likely short lived.

The lesser-known part: testosterone is not what makes you attractive anyway

Even if a streak did raise testosterone a bit, it would not change your face.

A 2008 study found men's testosterone levels were linked to mating success, but not to how attractive or masculine they looked to others.
A big 2022 review pooled 96 studies and over 177,000 people. Voice pitch, height, and testosterone all predicted mating success a little, but strength and muscle were the strongest and only steady predictor. Facial masculinity did not predict it.

So if your goal is looking better, lifting weights does far more than any streak. That matches what many retainers end up saying themselves (see the next section).

What men on long streaks say (late October 2026)

We read dozens of posts from men doing retention in the last week of October 2026. Here is an honest summary of both sides.

The big wins usually come with other changes. A man at 35 days listed a deeper voice, less brain fog, a "slight glow," a denser beard, and a sharper jawline. But he also wrote that he had been very regular at the gym and that his jawline showed "due to cleaner healthy habits and regular workout."
Highs, then a flatline. A recently divorced man past 120 days said days 30 to 60 felt like "magical powers," with more energy, workouts every day, a leaner face, and better skin. Then the last 60 days went flat. He lost the drive to work out, felt more emotional, and was hard on himself for not keeping the high.
Some feel worse. An 18 year old at 52 days said the only real change was feeling "more angry horny and sad," and that women seemed to like him even less. Another man said that after 2 months he noticed no change at all and life had become "more boring."
Even believers question the attraction claim. One man asked if the extra attention from women is real or if men on streaks "are simply noticing more of the attention they get."
The stories get stranger. Posts this week credited retention with luck, green traffic lights, a shy cat that suddenly loved a stranger, and women "out of my league" making moves. None of this can be tested, and it shows how fast the claims drift away from the body.
Shame over wet dreams is common. A man 40 days in woke up after a wet dream asking if he had "broken" his streak and said he felt ashamed. Others asked if one slip erased all their "benefits."
Some push back on the science. One poster argued that doctors say there are no downsides to masturbation when little research exists, and that the prostate cancer study counted sex too. That last point is fair (more on it below).

New research (2026): what long streaks do to sperm

The newest science on abstinence is about sperm, and it does not favor long streaks.

Aug. 6, 2026 review. A large review of 82 studies found that longer gaps between ejaculations raised semen volume and total sperm count, while shorter gaps gave better sperm movement. The authors rated the evidence low certainty.
March 2026 review in Proceedings of the Royal Society B. This Oxford led review pooled 115 human studies and 56 animal studies. In men, storing sperm through abstinence raised oxidative stress and DNA damage and lowered sperm movement and survival. The authors call it sperm aging.
Sept. 22, 2026 study. A study of 2,782 men at a fertility clinic in Qatar found DNA damage in sperm rose steadily with longer abstinence. As reported on Oct. 16, 2026, average DNA damage went from about 27.8% after 1 to 2 days to 34.2% after 7 or more days. The authors suggest no more than 4 days of abstinence before a DNA damage test.
Sept. 22, 2026 Medscape summary. A review of this research concluded that more days without ejaculating do not mean better odds of having a child. The World Health Organization range of 2 to 7 days is for keeping lab tests consistent, not for boosting fertility.

None of this is about looks. But it does kill the claim that holding it in makes you more "potent." If you and a partner are trying for a baby, a month long streak works against you.

The prostate question

A large Harvard study followed 31,925 men for about 18 years. Men who reported 21 or more ejaculations a month had about a 19% lower risk of prostate cancer than men who reported 4 to 7. The skeptic above is right that it counted all ejaculation, not just masturbation, and that it is an observational study, so it cannot prove cause. But it is the biggest study on the topic, and it points the opposite way from the retention claims.

Why some men really do feel better

There is a fair case for a month off, and it is mostly not about semen.

Less porn can mean more time and less shame. Many men use the month to cut porn, which frees hours and can help if they felt their use was out of control.
Withdrawal is not a given. A 2023 trial had 176 regular porn users either stop for 7 days or carry on as usual. Overall, stopping did not cause withdrawal style symptoms.
Belief shapes the urge to quit. A 2020 survey of 1,063 people found the drive to quit masturbation was tied mostly to seeing it as unhealthy, plus conservative views, religion, and lower trust in science. It was not tied to behavior like how often people actually had orgasms.
A goal gives structure. Men who stack the challenge with gym time, sleep, and fewer late nights often see real changes in their face and body. The habits do the work, and the streak gets the credit.

The darker side is real too. A January 2026 study of a large semen retention forum found that users framed it as self mastery and as resisting a society they see as in decline, and that claims it cures mental health problems have no support. The authors linked the fear of "losing" semen to Dhat, a known pattern of distress over semen loss first described in South Asia. The shame over wet dreams and "relapses" in the posts above fits that pattern.

Lesser-known tips if you try it anyway

Pick your real goal. If it is cutting porn, say so and track that. If it is looks, put the energy into lifting, sleep, and grooming, because those have evidence.
Do not judge your face by your streak count. Take the same photo in the same light on day 1 and day 30. Most "glow" claims vanish in a side by side.
Wet dreams do not undo anything. They are a normal body process. Treating them as failure feeds the shame loop the 2026 study described.
Skip it if you are trying to conceive. The 2026 sperm research points the other way.
Watch your mood. If you feel angrier, sadder, or more fixated as the days go on, that is a real cost, not a test to push through.

Bottom line

No Nut November will not change your face. The testosterone story rests on two tiny studies from over 20 years ago, the bump they found was short, and testosterone is not what makes faces attractive anyway. The 2026 research says long streaks make sperm older and more damaged, not stronger. What does help is the stuff men often add during the challenge: less porn, more lifting, better sleep, and more nerve to talk to people. Keep those and drop the magic. If you want to know whether your look is actually improving, The Face They See lets people of the opposite gender rank your photos for free, so you can compare a day 1 photo with a day 30 photo.
