Reproductive steroids are powerful hormones that play a key role in the growth and development of our bodies, especially during puberty. These natural chemicals, produced by the ovaries in women and the testes in men, shape physical changes such as breast development, muscle growth and fertility. Beyond these functions, reproductive steroids also influence overall health and well-being.
Dr Philippa Saunders, an expert in reproductive steroids, defines them as a group of essential hormones that regulate bodily changes. The most well-known among these are oestrogen, progesterone and testosterone. Oestrogen, primarily found in women, is responsible for breast development, the onset of menstrual cycles and preparing the body for pregnancy. Progesterone, also in women, thickens the uterine lining, making it ready for potential pregnancy.
