Hormone therapies can lead to various side effects by affecting the body's hormone production or interfering with the natural functioning of hormones. The type and severity of these side effects vary depending on the specific treatment administered, individual bodily response, and the person's sex. Since each patient responds uniquely to treatment, the same side effects may not be observed in everyone.
