östrogeenihormoonidega

Östrogeenihormoonidega is a Finnish term referring to estrogen hormones. Estrogens are a group of steroid hormones, the primary female sex hormones, though they are also present in males and play a role in both sexes. The main types of estrogen produced in the body are estradiol, estrone, and estriol.

In females, estrogen is primarily produced by the ovaries and plays a crucial role in the development and regulation of the female reproductive system and secondary sex characteristics. This includes the maturation of eggs, the menstrual cycle, and the development of breasts, body hair, and fat distribution. Estrogen also has significant effects on other parts of the body, influencing bone density, cardiovascular health, skin, mood, and cognitive function. Levels of estrogen fluctuate throughout a woman's life, particularly during puberty, menstruation, pregnancy, and menopause.

In males, although produced in much smaller amounts, estrogen also has important functions, including regulating libido and sperm production. It also contributes to bone health.

Synthetic estrogens are used in various medical treatments, such as hormone replacement therapy (HRT) for menopausal symptoms and as components of hormonal contraceptives. Understanding estrogen hormones is vital for comprehending reproductive health, hormonal imbalances, and the effects of various medical interventions.
