Low progesterone is one of the primary hormone imbalances affecting women in the western world. This can be especially troubling when you consider that about 1 in every 8 couples has difficulty getting or staying pregnant, and progesterone is the hormone of pregnancy.
Progesterone and infertility
Progesterone helps to maintain the uterine lining so that the newly fertilized embryo is able to implant and the pregnancy is able to progress. Low progesterone often results in something called Luteal Phase Defect, which means that the phase in which the uterine lining is maintained by progesterone decreases to less than 9-10 days. This results in the shedding of the uterine lining, aka the period, before the embryo has a chance to implant in the uterus.
If pregnancy occurs, the body rapidly ramps up its progesterone production, which remains high throughout the duration of the pregnancy. Without adequate progesterone, pregnancy cannot be sustained.
What about those of us who aren’t trying to conceive? Low progesterone is still a problem for us, too.
