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 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.
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
Maintains the Secretory Endometrium which Feeds the Ovum & Resultant Embryo
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 (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.
