According to a few studies ( here, here, and here), there are many different LH surge patterns: 42%-48% of cycles have a short LH surge before ovulation 33%-44% of cycles have two LH surges (an initial big rise, small drop, then a second rise in LH) and 11%-15% of cycles have a 'plateau' pattern (when levels of LH remain high after an initial surge).Another study shows that the average LH surge was characterized by a 7.7-fold increase in LH from baseline - but LH surges ranged from 2.5-fold to 14.8-fold increases from baseline.If you track your LH and discover this, it's worth bringing up to your doctor. Values considerably below the average lower limits and above the average upper limits might be indicative of an underlying condition that may impact ovulation.Yep - some women had an LH of 6.5 the day before ovulation! One large study showed that the median LH on the day before ovulation was about 44.6 mIU/mL, but that LH could be as high as 101, or as low as 6.5.The main takeaway: There is a wide range of what's considered вЂњnormalвЂќ for urinary LH

WhatвЂ™s considered a вЂњnormalвЂќ pattern of LH around ovulation?.What is a вЂњnormalвЂќ LH level on different days of the cycle?.More specifically, weвЂ™ll take a look at what science has to say about these two important questions: In this post, weвЂ™ll highlight findings from a few of our favorite studies that lead us to question what вЂњnormalвЂќ really means in the context of LH across the cycle. In fact, LH levels and LH patterns across the cycle are far from being one-size-fits-all. And if youвЂ™re trying to conceive, testing for LH surges can help you time sex or insemination around your fertile window (the five days leading up to and the day of ovulation) - when you have the highest chances of getting pregnant.Д«ut just because mid-cycle surges in LH are necessary for ovulation doesnвЂ™t mean LH levels look the same across all people and all cycles. Of all the cycle-tracking methods out there, LH testing ranks high on our list of favorites because of its clear role in inducing and predicting ovulation - a mid-cycle surge in LH is absolutely necessary for ovulation to occur. If youвЂ™re someone looking to track when you ovulate, chances are youвЂ™ve heard of luteinizing hormone (LH). This article was last updated April 27, 2021.
