Micropenis, also called microphallus, is a real condition, but it’s actually quite rare. In fact, studies show that of boys born in the U.S. in the years 1997-2000, only 0.015% had micropenises. That’s 1.5 in 10,000. Of the adult male population worldwide, only approximately .6% have micropenises. Let’s take a deeper dive into what causes micropenis and treatment options for this rare condition.
What is a micropenis?
Typically diagnosed at birth, micropenis is a condition in which the penis looks and functions just like a normal penis, but it’s significantly smaller in size. To diagnose, a physician will measure penile length. For perspective, an average-size adult penis has a stretched penile length, or SPL, of 5.25 inches (Cleveland Clinic). A micropenis is diagnosed when the SPL is 3-and-two-thirds inches or less. It’s not uncommon for men who have smaller penises to worry that they may actually have a micropenis, but that’s likely not the case. Penile length is based on the length of the erect penis, which is often approximated by stretched penile length, as noted above. A small flacid penis is probably normal, if it stretches. If you have questions or concerns about your penis size, consult with your physician.
What causes micropenises?
While genetics are thought to possibly play a role in the development of a micropenis, there are other potential and more likely causes as well. In fact, fetal testosterone deficiency is the leading cause of micropenis, and that testosterone deficiency is most often caused by a condition called hypogonadotropic hypogonadism. Easier to explain than to say, hypogonadotropic hypogonadism occurs during fetal development when the hypothalamus in the brain does not properly secrete hormones that signal to the testicles that they need to produce testosterone, a hormone that is essential for a male’s reproductive organs to grow and function in a normal fashion. That lack of testosterone is what can lead to the development of a micropenis.
Is there a cure for micropenis?
While there is no “cure” for micropenis, there are treatments that may help. Testosterone treatment is one option that, if pursued, should begin in infancy. This micropenis treatment option can be administered via testosterone injections or testosterone ointment application. The goal is to see if the testosterone stimulates growth in the penis, thereby adding length to the penile shaft. If it does work, testosterone treatments may be considered again when the patient reaches puberty age.
Although there is a surgical procedure for micropenis, phalloplasty, it is only rarely utilized. As with any surgery, micropenis surgery comes with its risks, so it’s imperative to have a frank and honest discussion with your doctor so you’re acutely aware of all potential outcomes.
Final thoughts
Micropenis is a rare condition, and there are treatment options available. If the treatments do not work, however, it may be beneficial to seek counseling to help you cope with the condition so you can enjoy a happy life.
