### process | secretion | hormone:

Progesterone
* Most progesterone causes secretion.
* Most progesterone helps endometriums
  - wombs
  - maintains pregnancy
  - prepares uteruses
* Some progesterone becomes dominant hormones
* Some progesterone causes effects
  - side effects
  - has effects
  - influences pituitary glands
  - maintains conditions
  - prepares glands
* VERY important part of hormone therapy.
* acts as a natural diuretic and has a constricting effect on blood vessels and muscles
  - regulator for the entire endocrine system
* again becomes the dominant hormone.
* alone can help that, as well.
* also acts as a natural anti-depressant and sedative to the nerves
  - with estrogen on breast tissue
  - causes thickening of cervical mucous
  - enhances the libido, especially in females
  - has a role to play in the management of breast cancer
* also helps create a balance of all other steroids
  - with the effects of estrogen dominance
  - inhibits the contractions of smooth muscle cells of the myometrium
  - interferes with insulin
  - prepares the oestrogen-primed endometrium for implantation of the fertilized ovum
  - promotes complete development of the alveoli of the mammary gland
  - provides an added health benefit by building bone mass
* also slows down the movement of the stomach muscles, making digestion sluggish
  - wavelike contractions of the stomach, making digestion sluggish
* also stimulates bone building and thus helps protect against osteoporosis
  - bone-building and thus helps protect against osteoporosis
  - glands in the endometrium
  - strengthens bones
* balances the effects of estrogen exposure
  - estrogen level in the body, thus lessening the risk
  - estrogens that build in a man's body
* blocks the effect of estrogen.
* breaks down in the stomach when taken orally.
* can also prevent ovulation and reduce circulating estrogen levels
  - cause bloating, breast tenderness, irritability and depression
  - even make estrogen if it's needed
* causes changes in the endometrial lining which prepare it for pregnancy
  - lining of the womb which protect it from cancer
  - maturation of the oocyte to produce the egg
  - new blood vessels to grow within the uterine lining
  - sleepiness
  - smooth muscle tissues, such as the bladder, to relax
  - stromal cells to store glycogen, conn
  - the endometrium to mature so that it can support the egg after it is fertilized
* changes from one hour to the next
  - the consistency of the vaginal mucus so that it becomes tacky or sticky
* comes in tablets, vaginal gels, and an intrauterine device
  - mainly from the ovaries and a very slight amount comes from the adrenal glands

* is one of the hormones essential for regular menstrual periods
  - that decline as a woman reaches menopause
  - two main hormones produced by the ovaries
  - two primary hormones produced by the female body
  - present only as a trace
* is produced after ovulation by cells in the now empty egg follicle
  - the corpus luteum, which forms on the ovary
  - both during the menstrual cycle and during pregnancy
  - in the ovaries during the second half of the menstrual cycle
  - only after ovulation
  - produced, after ovulation, by the cells of the corpus luteum
  - protective against cancer caused by excess estrogen
* is released from the corpus luteum in several large bursts during the day and night
