Oestrogen
* also play a part as the cell receptors for progesterone are oestrogen-dependent.
* are essential for helping the tissues keep their strength and elasticity.
* can increase the number of proliferating cells in the human endometrium in vivo.
* have very broad effects in the body.
* reduces milk output.

Estrone
* Most estrone is formed in peripheral tissue from androgens secreted by ad.
* appears to increase risk of breast cancer.
* are drugs
  - estrogens
* does the same work that estradiol does, but it is considered weaker in it s effects.
* increases the activity of osteoblasts, the cells that build bones.
* is an oestrogen
  - another estrogen that occurs naturally in the human body
  - converted from estradiol in the liver
  - much less potent than estradiol but has the same function
  - produced by the fatty tissues
* is the estrogen most commonly found in increased amounts in post menopausal women
  - hormone thought to be responsible for breast cancer
  - oxidized form of estradiol
  - thought to be the estrogen primarily responsible for breast cancer
* precursor to estradiol.
* relatively strong estrogen.

Progestin
* -These medications mimic the action of progesterone.
* All progestins are synthetic hormones.
* Some progestins also have adverse effects on cholesterol levels
  - can also reverse the benefits of estrogen on lipid and carbohydrate metabolism
  - impart a higher risk of associated thromboembolism
* act by establishing a state of false pregnancy in women.
* also can demonstrate estrogenic, anabolic, and androgenic activity.
* are also mild, direct stimulants of the respiratory center
  - low during the follicular phase and increase following ovulation
  - one of the female hormones
  - steroid hormones
* are synthetic compounds that are designed to mimic the actions of natural progesterone
  - intended to mimic the actions of natural progesterone
  - bear some similarities to natural progesterone
  - progesterone-like drugs prescribed as pill or injections
  - steroids
* can also be responsible for a person feeling tired or fatigued
  - increase a woman's risk of heart disease, liver disease, and lung disease
* have some limited advantages.
* help to regulate the effects of estrogens.
* helps prepare the lining of the uterus for a potentially fertilized egg
  - protect against uterine cancer
* offsets the cancer-causing effect.
* produce an endometrium that is unfavorable to blastocyst implantation.
* reduces the risk by causing monthly shedding of the endometrium
  - of cancer by causing monthly shedding of the endometrium
* refer to the synthetic compounds with the properties of progesterone.
* seem to give mood side effects in many women.
* thins the lining of the uterus and prevents it from shedding.
* works in a manner similar to breast-feeding.

Synthetic progestin
* is used as a contraceptive.
* occupy progesterone receptors and thereby block progesterone function.

Progestogen
* Many progestogens have oestrogenic activity and can modify the effects of oestrogens.
* can be either natural or synthetic.
* is added when a woman has an intact uterus
  - important in protecting against cancer of the uterus
  - taken in pill form
