Oestrogen

Oestrogen (or Estrogen in American English) is the primary female sex hormone. It is responsible for the development and regulation of the female reproductive system and secondary sex characteristics. There are three major endogenous estrogens in females that have estrogenic hormonal activity: estrone, estradiol, and estriol. The estrane steroid estradiol is the most potent and prevalent of these.

Types of Oestrogen[edit | edit source]

There are three types of oestrogen, namely:

Estrone: This is the only type of oestrogen that the body can make after menopause. It is produced by the ovaries and fat cells.
Estradiol: This is the most common type of oestrogen and is primarily produced in the ovaries. It is the strongest type of oestrogen and plays a crucial role in the menstrual cycle and fertility.
Estriol: This type of oestrogen is produced in large amounts during pregnancy.

Functions of Oestrogen[edit | edit source]

Oestrogen has many functions, including:

Regulating the menstrual cycle
