LH lower than FSH

[Anonymous]

I know if your FSH is higher than your LH it may indicate PCOS.

But if FSH is lower than your LH (both within "normal" ranges) does that point to DOR?

I am a month away from turning 37 and my labs are so much worse than they were a year ago!

I thought it was the opposite- if your LH is higher than your FSH that could signal PCOS?

I have a very low LH (on the lowest end of normal). I was told my RE that he often sees low LH with a low BMI (mine hovers between 19.5 and 20). The proportion of my FSH to LH is a 2.4 to one, which can indicate DOR but not always.

According to Dr. Sher, a high LH is often present in perimenopausal females.

Expert here- for PCOS your LH is higher than your FSH on day 3. Normally your FSH is higher, because LH stays very low until a surge at O time.

High FSH indicates DOR (FSH is like stepping on the gas, and when your ovarian reserve gets low, body steps on the gas even harder to send signal)

OP here, yes sorry. I mixed them up. These were my results:

Estrogen- 57
FSH- 8.5
LH- 3.7
Prolactin -6.9
TSH 1.4

I had a mock and endo biopsy done today (CD7) and my AFC was 13, so I hope I am ok for a little bit.

It just seems like a flag that my FSH to LH used to be 1:1 and now it's closer to 2.3:1

Hi OP- this is the PP.

Your estrogen could be suppressing your FSH a bit (SG wants under 50).

We did IVF. We have severe MFI.

I had a fairly good reaction to stims and my AFC was 14-20 (two different baseline readings), FSH was 6 and LH was 2.5.

As I mentioned earlier, I had read that the LH-FSH ratio could indicate DOR but my doctor wasn't concerned about it.

Your numbers are absolutely fine. I wouldn't stress. And you won't know until your cycle (and there is variation from cycle to cycle).
