Unfortunately, steroids result in hormone imbalance. Teenagers basically need a healthy hormone balance, which is essential to the development of physical traits in both girls and boys. However, when kids is abusing steroids, they are actually making some gender confusion or mix-up. For instance, boys can have shrunken testicles or low sperm count (as early as their age). They can even end up having breasts, also known as gynecomastia. On the other hand, girls who use steroids will develop more masculine features, such as too much body hair or decrease in breast size.
