Ösztrogénhatás

Ösztrogénhatás refers to the biological effects produced by estrogen, a group of steroid hormones primarily produced by the ovaries in females, but also present in smaller amounts in males and produced by other tissues. These hormones play a crucial role in the development and regulation of the female reproductive system and secondary sex characteristics. The effects of estrogen are widespread, influencing various bodily functions beyond reproduction.

Key physiological processes influenced by estrogen include the growth and maturation of the uterus, fallopian tubes, and vagina, as well as the development of breasts and the characteristic female body shape during puberty. Estrogen also plays a vital role in the menstrual cycle, regulating the shedding of the uterine lining and ovulation. Beyond the reproductive system, estrogen impacts bone density, cardiovascular health, and even brain function, influencing mood and cognitive processes.

In males, estrogen contributes to sperm maturation and libido, though at significantly lower levels. Disruptions in normal estrogen levels, either too high or too low, can lead to various health issues in both sexes. These can range from menstrual irregularities and fertility problems to increased risks of certain cancers and bone disorders. The term "ösztrogénhatás" encompasses the entire spectrum of these diverse biological actions.
