Female hormones need to be conceded in a relative fashion to each other.
Female hormone ratios are more often important than absolute levels.
Female hormone range of normal is large and if levels are repeated on a different day other female hormones should be repeated as well.
Female hormone levels required knowledge of the timing of the menstrual cycle.
Steroidogenesis pathway is complex, and fluid with female hormones that can be changed back-and-forth between progesterone, estrogen, and androgens depending upon enzymes at any given time in the cycle.
Enzymes vary from tissue to tissue and from day today and can influence steroidogenesis.
Enzymes interact with thyroid, adrenal, insulin/leptin, IGF 1and 2, GH, prolactin and other hormone pathways.
Female hormones influenced by pituitary and hypothalamic regulators, and a function at the autocrine, paracrine, and intracrine levels.
Female hormones have different functions at different levels and concentrations.
Female hormones at high-level may have a function that is opposite of low levels of the same hormone.
Female hormones are protein-bound, and only the unbound part is active.
Female hormone binding proteins may be more important than the apps level of the hormone themselves.
FH usually function on negative feedback loops but at some concentrations function with positive feedback loops.
Surges on certain days are important for ovarian function and long-term health.
Steroid hormones can bind with each other’s receptors to some degree and activate them.
Female hormones are progesterone with 21 carbons, androgens with 19 carbons, and estrogens with 18 carbons.
FH are made from cholesterol with 27 carbons.
FH can easily be converted back-and-forth between the three families.
