Which of the following is a common negative side effect of anabolic steroids in men?

Breast development, or gynecomastia, is a well-documented side effect of anabolic steroid use in men. Anabolic steroids can disrupt the hormonal balance in the body, leading to an increase in estrogen levels or estrogenic activity. When these steroids are consumed, they can convert androgens into estrogens, which can stimulate breast tissue growth. This phenomenon not only reflects the hormonal changes induced by anabolic steroids but also highlights the risks associated with their misuse, particularly in a population that may seek these substances for physical enhancement or performance improvement.

The other options highlight different hormonal effects that are not typically associated with anabolic steroid use in men. Inhibition of follicle formation, for instance, is more relevant to women and reproductive function rather than men. Increased vocal pitch and reduced body hair are also not common side effects; in fact, anabolic steroids often lead to deepening of voice and increased body hair due to the androgenic effects associated with these substances. Thus, breast development stands out as a notable adverse effect linked to the use of anabolic steroids in men.
