Estrogen
oestrogen, estradiol, estrone, estriol
If we named hormones according to their place of origin, as Selye suggested, we could call estrogen folliculin (as Selye did because it is produced abundantly in the ovarian follicle), or adipin, because it is sometimes produced in fat cells. But it can be produced by many cells when they are under stress, and it seems to be normal for some to be produced in the testicle.
Estrogen is a group of ovarian hormones that includes estradiol, estrone, and estriol, and is often referred to as "folliculin" due to its production in the ovarian follicle.
Estrogen has various functions in both males and females, and its antifertility actions and toxicities have been extensively studied over the last 100 years. Despite its reputation as a "female hormone," estrogen is also produced in the testicle and can be produced by many cells when they are under stress.
Estrogen is involved in the process of renewal and growth, and can eliminate recently recorded information, restoring the underlying primitive capacity for growth. It has been demonstrated that estrogen stimulates the adrenal glands, independently of the pituitary's ACTH, which can increase the production of androgens.
The ratio of progesterone to estradiol is important for prostaglandin metabolism during human delivery, and a well-balanced equilibrium of these hormones is necessary for proper uterine function. However, the levels of estrogen and progesterone in the blood do not always correlate with the tissue biochemical changes that occur during delivery.
A high-fiber diet may reduce serum oestrogens by altering the colonic transit rate, which affects the proportion of oestrogen that is deconjugated and/or absorbed. Additionally, the estradiol produced by the gonads is the main source of estrogen in the blood, and blood estrogen levels can indicate ovarian function in women and gonadal function in men.
However, serum steroid levels are not a good surrogate for tissue steroid levels, and tissue levels of estrogen can be an order of magnitude higher than serum levels. This suggests that estrogen dominance may be a more common condition than previously thought, particularly in menopause.
