About 0,6 of the boys is born with a micropenis.
One normally speaks of a micropenis if a newborn has a penis smaller than three quarters of an inch (1,9 cm) or an adult has one that is smaller than 1,5 inch (3,8 cm).You measure it at the top of the penis, from base (the pubic bone) to the tip of the penis, while stretching it.
Sometimes the cause is clear, but not always. It can for instance be the result of a chromosome abnormality, an insensitivity of the body to male hormones, a testosterone insufficiency or a problem related to the central nervous system. When parents seek help in time hormone therapy may help, stimulating the growth of the penis.
If you think you have a micropenis go to your GP to have it checked out.
Those with a micropenis normally enjoy sex. They get excited, have erections and climax like other guys. They cannot have intercourse, but often make up by being more creative when having sex. The worst part is that as a child they are often ragged, for instance when showering together with others. This can make it hard for them to accept their own body. Fortunately this is often temporarily. Research has shown that most men with a micropenis feel good about themselves and have satisfying (sexual) relationships.
