Which of the following is NOT a side effect of anabolic steroids in women?

Heightened estrogen levels is not typically associated with the use of anabolic steroids in women. Anabolic steroids are synthetic derivatives of testosterone, which means that their use generally leads to an increase in testosterone levels rather than estrogen. Anabolic steroids can indeed cause various side effects in women, including hair loss, increased facial hair (hirsutism), and hypertrophy of the clitoris due to the androgenic effects these substances can exert. These side effects result from the body’s adaptation to elevated levels of androgens, which can disrupt normal hormonal balance. Therefore, heightened estrogen levels would not be a direct effect of anabolic steroid use but rather a consequence of other hormonal interactions, making it the correct choice for the question regarding non-side effects.
