### process | secretion | hormone | progesterone:

Natural progesterone
* Some natural progesterone causes effects
  - side effects
  - has effects
* can actually help build bone back
  - also help alleviate breast soreness
  - help to properly balance the estrogen and progesterone ratios
* counterbalances the effects of estrogen dominance.
* has no side effects and is recognized and used by the body as needed
  - protective and balancing effects throughout the body
* is an important component in menopausal symptom management for many women
  - broken down by the liver too quickly when taken orally
  - chemically identical to progesterone found in the human body
  - created by the ovaries at the time of ovulation
  - extremely safe
  - identical to progesterone produced by the human body
  - less likely to cause mood disorders
* is needed for proper hormonal balance
  - to affect proper hormonal balance
* is needed to effect proper hormonal balance
  - imbalance
  - one of the most effective ways to prevent and reverse osteoporosis
  - the exact same hormone that is produced by a woman's ovaries
  - very useful to balance excess estrogen
* tends to have fewer side effects.

Synthetic progesterone
* differs in composition from the progesterone naturally found in the body.
* is used as a contraceptive.

Protein hormone
* Most protein hormones are produced by glands
  - pituitary glands
  - produce in glands
* Some protein hormones are actually glycoproteins, containing glucose or other carbohydrate groups
  - made by pancreases
* have no activity when taken by mouth, while steroid hormones do have activity.

Relaxin
* are hormones
* does seem to reverse many signs and symptoms of aging in fibromyalgia patients.
* increases serotonin levels.
* is of no value for the treatment of scleroderma.
* promotes connective tissue remodeling by inhibiting excess tissue formation.
* relaxes the muscles of the pelvic region at the time of childbirth.

Release hormone
* Most release hormones are secreted by hypothalami.
* Most release hormones regulate blood pressure
* Most release hormones stimulate anterior pituitaries
  - production
* inhibit secretion.

### process | secretion | hormone:

Reproductive hormone
* Most reproductive hormones influence development.
* Some reproductive hormones have effects on seemingly unrelated neurotransmitter pathways.
* affect the development of the nervous system.
* are critical to pregnancy success
  - important in the development of the breast in puberty and in lactation
  - one of the primary causes of breast cancer in the cat
* cause the cycles to start after puberty in sexually mature females.
* contribute to fat in the legs and butt.
