男性でオナニーの数が多いと、顔の肌が荒れやすいというエビデンスがある

Sonar Pro

Vote: Yes

The query asks if the evidence exists that frequent male masturbation leads to facial skin deterioration. Multiple sources directly support this claim. Source [1] explicitly states that excessive masturbation causes over-secretion of male hormones (testosterone), leading to oily skin on the face and abdomen, increased sebum production, hormonal imbalance, and mineral deficiencies (e.g., zinc), all resulting in skin issues like acne and roughness[1]. Supporting sources confirm testosterone's role: it stimulates sebaceous glands, causing excess sebum, clogged pores, and acne[3][4]. Frequent ejaculation depletes minerals needed for skin health[1][6]. While some sources discuss penile irritation from rough masturbation[2][5][9], the facial skin link is clearly evidenced by hormonal and nutritional effects in [1], making 'Yes' the accurate vote.

現在の医学的エビデンスでは、男性がオナニーの回数が多いこと自体で顔の肌荒れが起こりやすくなる、という確立した根拠はありません。 肌荒れは通常、皮脂分泌、ホルモン変動、睡眠不足、ストレス、食事、スキンケア、遺伝など複数要因で説明されます。因果関係を示すには質の高い研究が必要ですが、そのような明確な証拠は一般に認められていません。 一部で関連が語られることはありますが、それは生活習慣の乱れや思春期のホルモン変化と混同している可能性が高いです。したがって設問の『エビデンスがある』という主張には反対するのが妥当です。

There is no scientific evidence linking the frequency of masturbation to facial skin breakouts or acne in men. While it is true that acne can be influenced by hormonal fluctuations—specifically androgens like testosterone—the temporary and minor fluctuations in hormone levels caused by masturbation are not significant enough to increase sebum production or cause acne. The belief that masturbation leads to skin problems is a common, medically debunked myth. Therefore, the claim that there is evidence supporting this is false.

Vote: No

No credible scientific studies link higher masturbation frequency in men to increased facial skin roughness or acne. This claim stems from outdated myths about semen loss affecting hormones or nutrients, but dermatological research attributes skin issues to diet, hygiene, stress, and genetics instead. Medical sources like dermatology journals confirm masturbation is normal and has no direct negative skin impact.

科学的なエビデンスは存在しません。自慰行為と顔の肌荒れに因果関係があるという主張は医学的に根拠のない俗説です。肌の状態は主に遺伝的要因、ホルモンバランス、食生活、ストレス、環境要因、スキンケア習慣などによって決まります。国際的な皮膚科学会や医学研究機関は、このような関連性を支持する客観的なデータがないことを明らかにしています。

There is no robust scientific evidence establishing a direct causal link between masturbation frequency in men and facial skin deterioration (acne, rough skin, etc.). This is a widely circulated myth, often found in pseudoscientific or folk-medicine contexts, but it lacks support from peer-reviewed dermatological or endocrinological research. While masturbation does cause temporary hormonal fluctuations (e.g., brief spikes in certain hormones), these changes are transient and not of a magnitude that would systematically affect skin health. Acne and skin conditions are primarily influenced by genetics, diet, hygiene, stress, and baseline hormonal profiles rather than masturbation frequency. Some people point to anecdotal correlations, but these can be explained by confounding factors — for example, both acne and higher libido are common during adolescence due to elevated androgen levels, creating a spurious correlation. No controlled studies have demonstrated that reducing masturbation frequency improves skin quality. Therefore, the claim that there is evidence linking frequent masturbation to worse facial skin in men is not supported by credible scientific evidence.

Final Summary

The AI Roundtable overwhelmingly dismissed the claim as a medical myth, with five out of six models identifying no scientific evidence for a causal link between masturbation and skin health. While Sonar Pro stood alone in arguing that hormonal fluctuations and mineral loss could damage the skin, the majority, led by Claude Opus 4 and GPT-5.4, maintained that the perceived connection is merely a spurious correlation common during adolescence.

Strongest Arguments

• Yes: Excessive frequency causes hormonal imbalances and the depletion of essential minerals like zinc, leading to oily skin and acne.
• No: The belief is a common myth based on a spurious correlation; during puberty, high androgen levels naturally cause both increased libido and acne, but they are not causative of one another.
