What is "estrogen"?

Estrogen is a hormone primarily produced by the ovaries in females, although it is also present in smaller amounts in males. It plays a crucial role in the female reproductive system and has various effects on the body. Estrogen is responsible for the development of secondary sexual characteristics in females, such as breast development and the widening of the hips. It also plays a role in the regulation of the menstrual cycle and is involved in the maintenance of bone health. Additionally, estrogen affects mood, cognition, and cardiovascular health. Overall, estrogen is an important hormone involved in reproductive processes and the overall well-being of individuals.
