Treatments that involve the use of hormones or their antagonists are commonly referred to as hormone therapy or hormonal therapy. Oncologic hormone therapy, hormone replacement therapy (HRT), androgen replacement therapy (ART), oral contraceptive pills and gender-affirming hormone therapy are the major classes of hormonal therapy in addition to a few others. Some hormonal therapies will be discussed in detail under different chapters including oncologic hormone therapy, glucocorticoids and mineralocorticoids and insulin under antineoplastic agents, antiinflammatory steroids and antidiabetic agents, respectively. After studying this chapter, students will be able to:

• Explain all types of hormone replacement therapy including menopausal, androgens, and oral contraceptives.

 • Discuss the use of androgen replacement therapy (ART) in males with low levels of testosterone due to disease or aging.

• Describe gender-affirming hormone therapy such as feminizing hormone therapy and masculinizing hormone therapy. • Identify appropriate growth hormone therapy for growth hormone deficiency.

• Demonstrate understanding of thyroid hormone replacement in hypothyroidism and antithyroid therapy in hyperthyroidism.
