A low LH peak of 2.5 fold the median value of baseline, is enough to trigger ovulation – which means you don’t need very high values to ovulate!

What happens to LH levels after fertilization?

But once a developing egg follicle reaches a certain size — usually around the midpoint of your cycle — LH secretion surges to really high levels. This hormone surge is what triggers ovulation about 24 to 36 hours later.

Does LH rise after implantation?

Luteal Phase

Progesterone levels are at their peak around 1 week after the LH surge, which coincides with the timing of embryo implantation, only if fertilization of the egg has occurred.

What will an ovulation test say if you’re pregnant?

The ovulation test might also be positive when you’re pregnant because a pregnancy-specific hormone, human chorionic gonadotropin (hCG), behaves a lot like LH on a molecular level (Cole, 2010). And while at-home ovulation testers are great at predicting ovulation, they’re ultimately a pretty simple tool.

What time of day is LH highest?

Ovulation is related in time to the onset of the LH surge, and occurs 40–45 h following the onset of this surge as detected in blood. The commonest time for the LH surge (as detected in blood) to commence is between 05:00 and 09:00. Repeated serum testing shows that 45% of LH surges commence at this time.

What causes no LH surge?

If your pituitary gland isn’t releasing enough LH and FSH, it can cause anovulation.

Participating in long-term excessive or intense exercise.

What happens if my LH doesn’t surge?

If you have not ovulated during your testing days, you will not have detected the LH surge. It is probable that ovulation has not occurred. At times, women may experience an anovulatory cycle during which an egg is not released. Unfortunately, the best thing to do is to continue testing.

Can I Miss My LH surge testing twice a day?

Ovulation tests may need to be done twice a day to avoid missing the peak. Luteinizing hormone, which is detected in the urine shortly before ovulation, peaks for different amounts of time and levels in different people. Sometimes, the peak time of luteinizing hormone is short and lasts only a couple of hours.

Can drinking too much water affect LH test?

For example, we know that if your urine is diluted (by drinking water beforehand, for example) it can affect your LH levels. If you’re someone that’s mega hydrating throughout the day and are likely to have very diluted urine, it may make surges harder to detect.
