Understanding Penis Growth Stages
Your penis doesn’t grow at a constant rate. Growth happens in stages, based on testosterone surges during puberty.
| Puberty Stage | Typical Penis Growth | Testosterone Levels |
|---|---|---|
| Stage 1 (Ages 9-11) | No significant growth | Low |
| Stage 2 (Ages 11-13) | Growth begins, slight length increase | Rising |
| Stage 3 (Ages 13-15) | Rapid length growth, girth starts increasing | High |
| Stage 4 (Ages 15-17) | Length slows, girth increases | Peak |
| Stage 5 (Ages 17-21) | Growth completes, slight girth increases possible | Adult levels |
📌 Most men stop growing by age 18, but some continue until 21.
