Progesterone Hormone
Progesterone
Serum levels
“Ovulation results in a mid-cycle surge of luteinizing hormone (LH) followed by an increase in progesterone secretion, peaking between day 21 and 23. If no fertilization and implantation has occurred by then, supplying the corpus luteum with human gonadotropin-drive growth stimulus, progesterone secretion falls, ultimately triggering menstruation. A day 21 to 23 serum progesterone peak of 6.5 to 7 ng/ml is the minimal level considered consistent with ovulation (emphasis added). A level in excess of 18 ng/ml is considered proof of ovulation."
Placental insufficiency has been associated with low levels of LH and progesterone.
Increased levels of LH and progesterone may be indicative of adrenal or testicular tumors.
