Estrogen & progesterone
Osmosis from Elsevier・2 minutes read
Estrogen and progesterone are essential female sex hormones produced by the ovaries, influencing the menstrual cycle, pregnancy, and menopause, with estrogen dominant in the follicular phase and progesterone dominant in the luteal phase. These hormones, derived from cholesterol, have systemic effects on the body, impacting puberty, reproductive organs, bone density, cardiovascular health, and skin elasticity throughout a woman's life.
Insights
- Estrogen and progesterone are the main female sex hormones, with estrogen dominant in the follicular phase and progesterone dominant in the luteal phase of the menstrual cycle. They are crucial for puberty, pregnancy, and menopause, impacting reproductive organ maturation, secondary sex characteristics, bone density, cardiovascular health, and skin elasticity.
- Estrogen and progesterone are steroid hormones derived from cholesterol, with enzymes converting it into pregnenolone, progesterone, and ultimately into estrogen. The placenta secretes estriol and progesterone during pregnancy, preparing the body for lactation. Menopause leads to decreased estradiol levels, making estrone the dominant estrogen produced by the body.
