In men, diet is rarely a major driver of high estrogen: most foods labeled “high in estrogen” contain phytoestrogens that only weakly activate estrogen receptors, while most estradiol is made inside the body when aromatase converts testosterone into estradiol in tissues such as body fat. If your estrogen-to-testosterone balance is off, here’s what the research ...

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

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

Dec 23, 2025 · 11 min read

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 ...

How much deep sleep do you need for recovery and hormone optimization?

Dr. Jonathan Pierce, PhD: Clinical Psychologist & Neuroscience Specialist

Dec 21, 2025 · 9 min read

Deep (Stage 3 NREM) sleep should make up about 13%–23% of your total sleep time—roughly 60–110 minutes per night if you sleep 7–8 hours—for optimal physical recovery and hormone regulation. Because this slow‑wave window drives growth hormone release, supports overnight testosterone production, and powers the brain’s glymphatic “rinse cycle,” you can feel run‑down even when ...

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

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

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 ...
