FSH levels differ depending on what day of the month they are
tested on. The general base is to get a cycle day 3 FSH.
Anything under a level of 10 is considered to be within normal
levels that would allow for pregnancy to occur. Anything over 10
means that the ovarian reserve is getting low or the remaining
eggs are of poor quality. FSH levels can also differ from month
to month. A woman trying to get pregnant could well get an FSH
level of 15 one month and would have a poor chance of achieving
pregnancy but could get a level of 9.5 the next month and
achieve pregnancy. If you are testing for menopause, the most
accurate results occur after you have ceased to have a period. A
woman with an FSH of 40 for instance would be considered to have
a very poor remaining ovarian reserve but could still get
pregnant if she happened to ovulate one of her few remaining
good eggs. Testing FSH levels to determine if you are peri-
menopausal is considered to be highly inaccurate since the
levels can vary so much depending on
