Does creatine cause erectile dysfunction? The evidence says no

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

Jan 01, 2026 · 9 min read

In healthy adults, creatine monohydrate has not been shown in human studies to cause erectile dysfunction or lower libido. Because creatine’s main job is recycling ATP for muscle energy—and the rumor often comes from confusing kidney-disease–related ED with supplement use—here’s what the evidence supports and what to do if erections change. “When patients ask ‘does ...

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

Dec 26, 2025 · 12 min read

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. This step-by-step plan shows you how to reset “conditioning” and when numbness is a nerve, vascular, medication, ...

Does having sex increase testosterone? The truth about bedroom habits and hormone levels

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

Sex and ejaculation can cause a short-lived testosterone rise of about 2 ng/mL, but levels typically return to baseline within 10–20 minutes, so it doesn’t meaningfully increase long-term testosterone. The bigger picture is a bidirectional feedback loop—testosterone drives libido, while arousal triggers a brief neuroendocrine surge—and why overall health often explains the “high T” sex-life ...

Does testosterone make your dick bigger? The clinical reality of growth, hormones, and male anatomy

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

Dec 21, 2025 · 10 min read

In adult men, increasing testosterone above normal levels does not make the penis bigger after puberty (typically complete by ages 18–21) because the corpora cavernosa have reached “terminal size” and don’t restart androgen-driven growth. Low testosterone can still make size look smaller by causing penile tissue atrophy and reduced elasticity—here’s what hormones can and can’t ...

Does testosterone affect how long you last? The science of stamina

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

Dec 19, 2025 · 11 min read

Testosterone mainly supports libido and erectile function, but it doesn’t directly increase Intravaginal Ejaculatory Latency Time (typically about 5–7 minutes) because ejaculation timing is largely a serotonin‑mediated neurological reflex. Low testosterone can still make you feel like you’re finishing “too fast” by destabilizing erections and creating a rush-to-finish pattern—here’s what actually controls stamina and when ...
