- Human penises vary in size on a number of measures, including length and circumference when flaccid and erect.
- Besides the natural variability of human penises in general, there are factors that lead to minor variations in a particular male, such as the level of arousal, time of day, room temperature, anxiety level, sport activity and frequency of sexual activity.
Average penis sizes around the world
- Average length when flaccid was from 7 to 10 centimetres (2.8 to 3.9 inches).
- Flaccid circumference/girth was between 9 to 10 centimetres (3.5 to 3.9 inches) when flaccid.
- When Erect the average length ranged from 12 to 16 centimetres (4.7 to 6.3 inches).
- When erect the circumference was around 12 centimetres (4.7 inches).
- Only men with a flaccid length of less than 4 centimetres (1.6 inches), or a stretched or erect length of less than 7.5 centimetres (3 inches) should be considered candidates for penile lengthening.
- Micropenis is a medical term for a small but normally structured penis.
- Hormonal or genetic factors can cause this condition. Healthcare providers often note the condition during the newborn to early childhood period.
- As long as no other health concerns are present, a micropenis can function normally.
- People with micropenis are still able to urinate (pee) and have erections.
- Androgens like testosterone are responsible for penis enlargement and elongation during puberty.
What are the symptoms of a micropenis?
- The most common micropenis symptom in babies is a penis that measures less than 0.75 inches when gently stretched. In adults, a penis that measures 3.67 inches or less when gently stretched is a micropenis.
What causes a micropenis?
- Micropenis is usually caused by fetal testosterone deficiency, which can be the result of a variety of conditions, including Prader-Willi syndrome, Kallman syndrome or, most commonly, hypogonadotropic hypogonadism.
- Hypogonadotropic hypogonadism occurs when your hypothalamus doesn’t secrete the hormones that stimulate your testicles to produce testosterone. This process is necessary for normal maturation and reproductive function.
How is a micropenis diagnosed?
- Your healthcare provider can diagnose micropenis with a physical examination.
- They’ll gently stretch your penis and measure it.
- The number is then compared to the size range of your particular age group.
How is a micropenis treated?
- The most common micropenis treatments include testosterone therapy and surgery.
