LH Level
Posted: Tue Apr 02, 2019 10:42 pm
Hi Doctor,
I am a 35 year old woman with a history of PCOS. My Day 3 LH:FSH ratio has always been high and I suffered from very long (35+ day) or absent cycles. I conceived my daughter in 2015 through cycle monitoring with Letrozole and a shot of Ovidrel. We are currently trying to conceive baby #2. I did my Day 3 bloodwork which was 5.3 IU/L for my LH and 5.5 for my FSH. I was very happy about this result as I have never had a 1:1 ratio before. Today is now Day 6 and I went to get my LH checked as I am using the ovulation predictor kits and they are becoming increasingly difficult to read and my LH is now 11.5 IU/L! The lab range cut offs are 2-12 IU/L for the follicular phase and 8 -90 IU/L for the ovulatory phase. I looked online and some graphs that show that LH is only supposed to rise close to ovulation. With my LH being this high (and having risen so much in just 3 days) is this likely to pose a problem if we try to conceive naturally or with meds? I have not yet gotten a positive LH surge reading on the at home ovulation tests but am fearful that I will without actually ovulating since I am so early in my cycle. Please advise.
