These levels change during a woman's normal menstrual cycle, so the history of having ceased menstruation coupled with high levels aids the diagnosis of being menopausal.
The underlying cause is due to the defective migration of GNRH neurons from olfactory placode to hypothalamus, leading to congenital GNRH deficiency. This leads to olfactory problems such as anosmia, optic defects like color blindness, and results in hypothalmic deficiencies associated with low levels of LH, affecting sex hormone testosterone in males or estrogen and progesterone in females.

The diagrams below take inter-cycle and inter-woman variability into account in displaying reference ranges for estradiol, progesterone, FSH and LH. Levels of estradiol (the main estrogen), progesterone, luteinizing hormone and follicle-stimulating hormone during the menstrual cycle. [88]
The stages of the menopause transition have been classified according to a woman's reported bleeding pattern, supported by changes in the pituitary follicle-stimulating hormone (FSH) levels. [57] In younger women, during a normal menstrual cycle the ovaries produce estradiol, testosterone and progesterone in a cyclical pattern under the control ...
