The average erect penis length is about 13 cm, and “celebrity” size claims are usually meaningless because flaccid photos, camera angles, and nonstandard methods (vs. bone-pressed erect length) can’t reliably indicate true erect size. Here’s how to measure accurately, stop misleading comparisons, and focus on what actually improves performance and confidence (like erection quality and ...

On TRT, a portion of injected testosterone is converted by the aromatase enzyme into estradiol, and about 15–20% of men develop elevated estrogen levels that can cause symptoms like water retention, nipple/breast tenderness, mood changes, and sexual dysfunction. Here’s how to recognize the pattern, why it can mimic low‑T, and what to adjust so your ...
