Pregnancy & Natural Progesterone
Interestingly, the word progesterone is given its name
because of its vital supportive role in gestation (Latin: gestare), a fact that
sheds some insight into its importance in pregnancy and the reproductive process.
Modern science confirms that insight, as, of all female hormones, progesterone
is the one most essential for conception and to the survival of the fertilized
egg and the fetus throughout gestation. It is necessary for full-term pregnancy.
At ovulation, progesterone levels rapidly
rise from 2-3 mg/day to an average of 22-25 mg. per day, peaking as high as 30 mg/day.
If fertilization does not occur in ten or twelve days, progesterone levels fall
dramatically, triggering the shedding of the secretory endometrium (the menstrual
cycle).
If pregnancy does occur, however, progesterone production is taken over by the
placenta which secretes an ever increasing supply, reaching 300-400 mg/day during
the third trimester!
Among the numerous other desirable effects
of Natural Progesterone are the following:
Makes Possible the Survival of the Fertilized Egg (successful pregnancy)
Maintains the Secretory Endometrium which Feeds the Ovum & Resultant Embryo (full-term pregnancy)
Progesterone Surge at Ovulation is the Source of Libido
Because progesterone is essential to prevent the premature
shedding of the supportive secretory endometrium, a significant drop in progesterone
levels or blockade of progesterone receptor sites during the first 10 - 12 weeks of
pregnancy may result in the loss of the embryo (failed pregnancy or miscarriage).
Dr. Katherine Dalton reports that women who use a properly
formulated progesterone cream during the first 19-20 weeks of pregnancy produce healthier,
more intelligent children.
