"Empowering Millennials: The Urgent Need for Menopause Research Funding"
Menopause occurs when estrogen levels decrease, leading to the end of the menstrual cycle, typically around age 51 in the US. Perimenopause, the period leading up to menopause, can last for several years and may begin in the late 30s or early 40s, with symptoms varying widely among individuals. Medical menopause can result from treatments like ovary removal surgery or chemotherapy, and may have more severe side effects than natural menopause.
