Rates
of ovarian hormones in woman before menopause.
Estradiol:
its blood rate varies from 0.06 nanograms per milliliter in
the proliferative part of the menstrual cycle towards 0.2
nanograms per milliliter in the secretory part of the
menstrual cycle
Testosterone:
its rate is on average of 0.57 + 0,19 nanograms per
milliliter throughout all ovarian cycle and
dihydrotestosterone levels are commonly the half of the
testosterone rates in healthy women (1).
Progesterone:
its blood rate varies from 0.3 to 1.5 nanograms per
milliliter (in the proliferative part of the menstrual cycle
towards 3 to 20 nanograms per milliliter in the secretary
part of the menstrual cycle.

IN WOMAN CONCENTRATION OF TESTOSTERONE IN PLASMA IS ALLWAYS
GREATER THAN ESTRADIOL CONCENTRATION (1)
The plasma concentration of testosterone is + or – 10 fold
the level of estradiol during the proliferative phase and +
or – 3 fold the level of estradiol during the secretory
phase
Serum levels of testosterone increases during ovulation
(Direct RIA) in
normal menstrual cycle.

Daily production of ovarian hormones
Estradiol: its daily production varies from 40 micrograms
per day in the proliferative part of the menstrual cycle
around 200 micrograms per day in the secretory part of the
menstrual cycle
Testosterone:
its daily production is of 200 micrograms throughout all
ovarian cycle.
The
progesterone: its daily production is of 4,200
micrograms during the proliferative phase of the ovarian
cycle and of 42,000 micrograms in the secretory part of the
menstrual cycle.
