Low LH and Successful Ovulation
We’ve now established that, although it’s highly unlikely, it is absolutely possible to be ovulating without ever having a positive LH test. LH tests forecast ovulation, but they don’t confirm it or provide information about the nature and success of ovulation, so what do you do if you never get a positive — and even if you do?
Even though ovulation is almost certainly to occur after an LH surge, there is no guarantee of this, especially if you have PCOS, other endocrine conditions, or a history of anovulation. Even in cycles that seem “regular,” ovulation may not actually occur.
It’s also possible to release an egg even in the absence of a positive ovulation test, but if your LH levels are too low, the follicle might not develop a healthy corpus luteum or produce enough progesterone for a healthy luteal phase and successful implantation of a fertilized egg. Even if you aren’t trying to get pregnant, having enough progesterone during the luteal phase of your cycle—the period that follows ovulation—is crucial to reducing your risk of miscarriage, supporting successful implantation, and maintaining general health.

Because every cycle is unique, tracking ovulation isn’t always a simple matter of black or white. In fact, many people completely avoid taking an ovulation test because it can be so confusing. We can assure you that once you realize the value of tracking your cycle, you’ll want to understand exactly how ovulation testing functions and what the results mean. We’ve addressed all the inquiries you didn’t even know you had about ovulation testing in order to spare you the time and patience of reading the lengthy, 6 point font instructions that are included with the majority of store-bought OPKs (ovulation predictor kits).
Let’s start with the basics. Luteinizing hormone (LH), a hormone that is measured by ovulation tests, is found in your urine. When it’s time to ovulate, LH signals to your ovaries from your brain. You may ovulate between 16 and 48 hours after taking the test if your LH levels are high. What you’re looking for in the results of your ovulation test is something called an LH surge.
Can a woman ovulate without the Luteinizing Hormone (LH)?
Without sufficient levels of the luteinizing hormone, also known as LH, a woman’s body cannot ovulate. This hormone induces ovulation and is made in the pituitary glands. LH typically reaches low levels during the first half of the menstrual cycle before surging just before ovulation.
When the follicles containing developing eggs reach a certain size at the halfway point of a woman’s cycle, it is known that the eggs inside are mature. The brain will then receive a signal to release the luteinizing hormone, which will result in ovulation and last for between 24 and 36 hours. If you’re trying to get pregnant, now is the time to have sex because LH is at its highest level. When mature ova are produced from the ovary, ovulation takes place, indicating the start of a fertile period.
When the ova is prepared, fertilization can begin and last for 12 to 24 hours. The egg will be released during menstruation if the required amount of time passes without the required amount of time passing before the egg becomes fertilized. A woman doesn’t need to have sexual relations only during this time period in order to become pregnant because male sperm can survive in a female body for up to seven days.
