Sex hormones include, but are not limited to estrogen, testosterone, progestrone and DHEA.
Estrogen, not one hormone, but a group of similar hormones of varying degrees of activity, is secreted by the ovaries throughout a woman’s reproductive years.
Estrogen is the female hormone that is responsible for ovulation. Estrogen plays an important role in a woman’s life from the time she begins puberty until the final menstrual period.
Not only does estrogen have beneficial effects on cholesterol; lowering blood cholesterol, and lipid levels, it also contributes the production of proteins, to bone strength and the a woman’s mental well-being.
Estrogen also supports and maintains the secondary female sex characteristics such as the distribution of fat in the breasts, hips and buttocks (which is what produces those wonderful womanly curves). It also influences pitch of the voice and distribution of hair on the body.
Progesterone, the second major sex hormone in women; is the other primary hormone produced by the ovaries each month during the second half of the cycle.
Progesterone is responsible for prepping and maintaining the uterus lining so it grows a thick layer of tissue in preparation for the fertilized egg. Progesterone is necessary for the survival of the ovum and then the resulting embryo; until the placenta takes over this task.
Progesterone also works on the breasts to prime the mammary glands for milk secretion. After menopause, progesterone stimulates osteoblasts to help build bone and increase bone density.
It is the natural decline in progesterone each month that triggers the menstrual cycle. Progesterone and estrogen are closely interrelated and their actions in the body are in a very delicate balance.
So balanced that a deficit of progesterone in the system can cause face and body acne to break out and in some cases, the acne can be so bad it can cause scarring.
