Testosterone and lifestyle factors

These notes combine advice from 10 reviewed passages across 3 workouts.

Overview

Coach’s claim

Coach makes several claims about testosterone. He says sunlight is one of the four biggest factors that raise it and external cold stimulation always increases it. He says ejaculation does not lower testosterone, being in a relationship should raise it further, and activity should raise it. He calls long-term abstinence harmful and NoFap unnecessary. He also claims that being around a baby sharply lowers testosterone. [1] [5] [6] [7] [8] [9]

Sunlight

Coach’s claim

Sunlight is one of the four biggest factors that increase testosterone. Sun exposure raises it. [1]

Cold exposure

Coach’s claim

External cold stimulation always increases testosterone. [9]

Coach’s claim

Some people may recommend cold exposure because they think it is more effective. [9]

Ejaculation and testosterone

Coach’s claim

Ejaculation does not lower testosterone. Testosterone increases with ejaculation, and it should also rise with the activities a person does. Being in a relationship should raise it further. Daily ejaculation can increase testosterone production even more. [5] [7]

Abstinence and NoFap

Coach’s claim

Long-term abstinence from ejaculation is harmful in the long run. Occasional release is inevitable and normal, and an unused organ weakens and eventually deteriorates, like a muscle. [4] [7]

Coach’s claim

Do not get into NoFap; it is unnecessary. Ejaculate about once a month. [6] [7]

Coach’s claim

Strict NoFap is unrealistic. Many athletes masturbate frequently, and it does not harm them. [2]

Coach’s claim

Quickly satisfying reproductive urges can reduce competitive drive and motivation for self-improvement. The body treats its reproductive purpose as fulfilled and stops pushing for development, which is the rationale behind NoFap. [3]

Babies and testosterone

Coach’s claim

Being around a baby lowers testosterone sharply, even when the baby is not one’s own. The smell babies emit drives the effect, and it is hormonal. [8]

Coach’s experience

In his own habits, the coach masturbates frequently and has never warmed to the NoFap approach. [2]
