Sea moss benefits for men: Fact checking the fertility superfood

Jan 06, 2026 · 9 min read

Sea moss does not have solid clinical evidence showing it directly boosts testosterone or male fertility, but its high iodine content can support thyroid hormone production (T4/T3), which indirectly affects energy and libido when a deficiency is present.

Dr. Alexander Grant, MD, PhD: Urologist & Men's Health Advocate

TRT best optimizes male performance when a man has clinically low testosterone (levels decline about 1% per year after age 30) because it replaces missing androgen directly, while growth-hormone secretagogue peptides target recovery and tissue repair by stimulating the pituitary to pulse more of its own HGH—so neither is universally “better” for longevity. Here’s how ...

How to make penis more sensitive: A urologist’s evidence-based plan to get sensation back

Dr. Alexander Grant, MD, PhD: Urologist & Men's Health Advocate

Penis sensitivity often returns when you stop desensitizing friction habits (high pressure, low lubrication) and address underlying medical causes—because sensation depends on skin receptors sending signals through the dorsal penile nerve and adequate blood flow to penile tissues.
