Which hormone's decline is commonly linked to the development of osteoporosis in postmenopausal women?

When oestrogen levels decline, such as during menopause in women, the body's ability to build new bone tissue decreases, while the breakdown of existing bone tissue may continue at a normal rate or even increase. This imbalance can lead to osteoporosis, a condition characterized by weak and brittle bones, making them more prone to fractures.
