Taken in conjunction with the FSH level, a higher level
of E2 on day 3 may be masking the true FSH level
. So, if FSH is in the normal range
, and E2 is high, the FSH may actually be higher than the number given. My dr said that E2 isn't indicative of anything taken on it's own (unless one is on fertility medications), but must be considered in light of FSH.
What was your wife's FSH level?
