Sex hormones

Progesteron

Progesterone is the most important agent of the progestogens and belongs in the group of sex hormones. In women, it is mainly formed by the corpus luteum in the ovaries and in much greater quantities during pregnancy from the uterus. The main proportion of this hormone in men is produced in the testes. Low progesterone levels are synthesised by men and women also by the adrenal cortex. Progesterone is formed in human bodies predominantly from cholesterol. Progesterone stimulates the growth of the uterine lining and prepares them for the embedding of a fertilized egg.

At the beginning of the menopause the progesterone level drops since progesterone production is linked with ovulation. If there is a sustained lack of progesterone in the body there will be an oestrogen dominance and consequently an increased risk of breast cancer and other serious conditions.

Essential functions of progesterone are:

Oestrogens

Oestrogens, also known as folliculin, are the most important female sex hormones in the class of steroid hormones. They are mainly formed in the ovaries in follicles and in the corpus luteum and to a smaller extent in the adrenal cortex. During pregnancy oestrogens are additionally produced in the uterus. Men also produce oestrogens in the testes in small quantities, and in addition a certain proportion of testosterone in the fatty tissue is converted to oestrogen by an enzyme.

In terms of the effects that they have, oestrogens behave in the mirror image of progesterone.

Essential functions of oestrogens are:

The three most important oestrogens:

Östradiol

Oestrone

Östriol

An oestrogen substitution should therefore include Oestriol alongside Oestradiol.

DHEA (Dehydroepiandrosterone)
