Microfalosomy is rare, and hormonal or genetic problems are the most common cause. Doctors usually diagnose it at birth.
What exactly is a micropenis?
Doctors diagnose micropenis when an individual’s stretched penis is 2.5 centimeters below the average standard for their age and level of sexual development.
Research has estimated that the average penis size for an adult is 13.24 centimeters when erect .
Average and micropenis size for each age range:
Full-term newborn: 3.2 cm (average) 2.4-2.5 cm (micropenis)
0–5 months: 3.9 cm (average) 1.9 cm (micropenis)
6-12 months: 4.3 cm (average) 2.3 cm (micropenis)
1-2 years: 4.7 cm (average) 2.6 cm (micropenis)
2-3 years: 5.1 cm (average) 2.9 cm (micropenis)
3-4 years: 5.5 cm (average) 3.3 cm (micropenis)
4-5 years: 5.7 cm (average) 3.5 cm (micropenis)
5-6 years: 6.0 cm (average) 3.8 cm (micropenis)
6-7 years: 6.1 cm (average) 3.9 cm (micropenis)
7-8 years: 6.2 cm (average) 3.7 cm (micropenis)
8–9 years: 6.3 cm (average) 3.8 cm (micropenis)
9-10 years: 6.3 cm (average) 3.8 cm (micropenis)
10–11 years: 6.4 cm (average) 3.7 cm (micropenis)
Adult: 13.3 cm (average) 7.1 cm (micropenis)
Is it very common to have a micropenis?
Micropenis prevalence statistics vary between studies. The micropenis and other birth abnormalities may be related to environmental factors such as parental exposure to pesticides during pregnancy. As a result, this condition may be more common in specific populations.
When a person has a micropenis, their internal genitalia and testicles are usually normal.
Causes
Hormonal problems are the most common cause of micropenis. Less commonly, they can occur when the mother experiences exposure to pesticides or other toxic chemicals during pregnancy.
Testosterone deficiencies, during pregnancy, are often the cause of micropenis and can also cause other genital abnormalities.
A testosterone deficiency can arise when a male fetus does not produce enough testosterone, or when the mother does not produce enough human chorionic gonadotropin during pregnancy, which stimulates the development of testosterone in the fetus.
When testosterone levels are normal, some medical conditions can prevent a person’s body from responding properly to testosterone. This response is called androgen insensitivity. When any of these hormonal problems arise, the penis of a male fetus may not develop in the usual way.
A male baby will experience a testosterone surge around 0 to 3 months after birth. This is a crucial period for penis growth. If this process is interrupted by hormonal problems, the baby could have a smaller penis than normal.
In rare cases, the micropenis is idiopathic, which means that doctors cannot find a specific cause. Because hormonal problems generally cause micropenis, people with this condition may also have other symptoms , such as hypogonadotropic hypogonadism, Prader-Willi syndrome, Kallmann syndrome, growth hormone deficiencies, abnormal chromosomes, or Laurence-moon syndrome. (LMS).
Does having a micropenis affect sexual function?
Most people with a micropenis have normal sexual function. It does not affect a person’s ability to urinate, masturbate, or have an orgasm. The only downside is that there are people who may have more difficulty urinating while standing up.
Anxiety about penis size can be a barrier to enjoying sex with a partner. Men can remain dissatisfied with their appearance even with treatment despite being able to have an active and healthy sex life. In this case, sex therapy is recommended.
Recall that, according to research published in 2018, only 18.4% of women reach orgasm only with vaginal penetration. Focusing on other sexual techniques, such as oral sex, can help a man with a micropenis feel more confident about sexual interactions, which can be positive for both of you.
