An AMH level above 1.5 suggests a woman is likely not perimenopausal and menopause is at least six years away if over 40.

“I think where the amh is helpful is when it's high so if your amh is above 1.5 um you know you're likely not perimenopausal in fact even if you're over 40 but your amh is over 1.5 menopause is probably at least six years away”

“prior to menopause towards menopause the amh drops very suddenly I mean it's you know within a period of about a year or two it goes from 0.6 to you know 0.1 uh and certainly less than that”

“so for example if your amh is below 0.2 and you're more than 40. uh then the probability that you're going to go through menopause in the next five years is very high”
