Penile Size Concerns and Hormonal Effects in Young Men - Urology

Share to:

The penis is very small when not erect, with almost only the glans and a little shaft visible?


I am currently 18 years old and severely obese.
I have excessive body hair, including pubic hair, armpit hair, and leg hair.
However, the length of my penis when not erect is very short and seems to have hardly grown since childhood.
Additionally, I do not feel that the foreskin has retracted; when not erect, it almost completely covers the penis, leaving only a small opening that does not obstruct urination.
When erect, the glans is only partially exposed, and the length is about 9 cm.
When not erect, the appearance is almost just the glans with a little bit of shaft visible, with the penis mostly retracted into the body, measuring about 4 cm in total, with the glans making up the majority.
(1) I would like to ask if this is considered abnormal and if I need to seek medical attention.
(2) Is the excessive body hair due to high hormone levels? Will this affect the development of my penis?

Hello: You should seek medical attention; excessive hair growth should not affect development.

It's understandable to have concerns about penile size and hormonal effects, especially during the formative years of late adolescence. Let's address your questions one by one, while also providing some context regarding hormonal influences and physical development.

1. Is my condition abnormal, and should I seek medical attention?
Based on your description, it sounds like you may be experiencing some developmental concerns that could warrant a consultation with a healthcare professional. The fact that your penis appears to be significantly smaller than average, both in its flaccid and erect states, could indicate a condition known as micropenis, which is defined as an erect penile length of less than 7 cm (approximately 2.75 inches). However, it's important to remember that penis size can vary widely among individuals, and many factors contribute to this variation, including genetics, hormonal levels, and overall health.

Additionally, the issue with your foreskin not retracting properly could suggest a condition called phimosis, which is common in younger males and can sometimes resolve on its own as one matures. However, if it causes discomfort or hygiene issues, it may be worth discussing with a urologist. A healthcare provider can perform a thorough examination and determine if there are any underlying hormonal or anatomical issues that need to be addressed.

2. Is the abundance of body hair due to high hormone levels, and does this affect penile development?
The presence of excessive body hair, particularly in areas like the armpits and legs, can indeed be associated with higher levels of androgens, which are male hormones such as testosterone. However, the relationship between body hair and penile size is not direct. While testosterone plays a crucial role in male development, including the growth of body hair and the development of the penis, the amount of body hair does not necessarily correlate with penile size or function.

It's also important to note that hormonal levels can fluctuate during puberty and may not stabilize until your late teens or early twenties. If you have concerns about your hormone levels, a healthcare provider can conduct blood tests to assess your testosterone and other hormone levels. If they are found to be low, hormone replacement therapy may be considered, but this should be approached cautiously and under medical supervision due to potential side effects.

In summary, while your concerns are valid, it's essential to consult with a healthcare professional who specializes in urology or endocrinology. They can provide a comprehensive evaluation, including physical examinations and hormonal assessments, to determine if any medical intervention is necessary. Remember that everyone's body develops at its own pace, and there is a wide range of normal when it comes to physical development. Seeking professional advice can help clarify your situation and provide peace of mind.
