Average Penis Size: How Studies Measure—and Why Self-Reports Run Bigger

Coconut Oil With Condoms and Toys: Lubrication Is Not Compatibility

Coconut oil is slippery, but it weakens latex and polyisoprene, is only conditional with polyurethane, and behaves differently across silicone, glass, steel and porous toys. Match the exact barrier, toy and body site.

Semen Sample Rules: How Many Days Should You Abstain—and Why Can Too Long Be Worse?

For semen analysis, WHO uses 2–7 days without ejaculation, while many labs require 2–5 or 3–5. Learn why longer can raise count but worsen other measures, and how collection and transport affect the result.
