If You Don't Understand Prolactin, You Don't Understand Masculinity

Overview

Nathan Sages argues that testosterone alone does not determine how men feel and that prolactin and other hormones should also be considered. He describes prolactin as an “energy killer,” linking high prolactin to low motivation, reduced focus, and lower testosterone-related markers. He presents his blood tests and client transformations as examples and promotes his hormone-coaching services.

His explanation centers on dopamine and lifestyle habits. He says frequent stimulation from scrolling, gaming, cannabis, alcohol, nicotine, caffeine, pornography, or masturbation can disrupt dopamine levels and, in turn, raise prolactin. He contrasts these habits with effortful activities he says support well-being, such as working, caring for family, and spending time outdoors.

Strategies and habits he recommends

• Avoid reaching for your phone first thing in the morning and reduce mindless scrolling.
• Read before bed instead of using your phone, and prioritize good sleep.
• Spend time in nature and work on managing stress.
• Limit highly stimulating habits, including gaming and the use of cannabis, alcohol, nicotine, and caffeine.
• Eat a balanced diet. He also advises limiting foods he associates with estrogen or prolactin, including oats, fenugreek, brewer’s yeast, fennel, leafy greens, nuts, legumes, and eggs.
• Consider hormone blood tests and discuss the results with a qualified clinician.
