Virilization is a condition in which a female develops characteristics associated with male hormones (androgens), or when a newborn has characteristics of male hormone exposure at birth.

Hypothalamus hormone production

The controlling hormones from the hypothalamus regulate hormone production by the pituitary. These hormones regulate body processes such as metabolism and control the release of hormones from glands like the thyroid, the adrenals, and the gonads (testes or ovaries).
