Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Dehydroepiandrosterone (DHEA) is an important endogenous steroid hormone. It is the most abundant circulating steroid hormone in humans. DHEA is used to treat systemic lupus erythematosus (SLE), osteoporosis, multiple sclerosis (MS), low levels of steroid hormones (Addison disease), depression, schizophrenia, chronic fatigue syndrome (CFS), and to slow the progression of Parkinson disease. It is also used for preventing heart disease, breast cancer, diabetes, and metabolic syndrome. DHEA is used for weight loss, for decreasing the symptoms of menopause, and for boosting the immune system. It is naturally produced in the human body.

So, the correct answer is option D.
