Ovulation Predictor Kits

Ovulation Predictor Kits

For the couple trying to conceive, the all important ovulation time period is key. You soon learn that everything is focused on this crucial window of time each month. Knowing when you are most fertile is the most important piece of data in trying to get pregnant.

Luckily for women wanting to conceive, home ovulation testing kits are available to make the process quicker, more reliable and private. These tests determine the level of LH or luteinizing hormone. This hormone is detected in the urine and typically a surge in LH levels signals the ovary to release an egg, or ovulation.

When: Timing of course is everything. You will need to perform the ovulation prediction test according to your own cycle. For instance, in a regular 28 day cycle you will want to start testing on day 11.

How Often: A test kit contains several test sticks and you will start testing on the day indicated by your cycle length and continue testing daily until the surge is detected in the monthly cycle.

How to Test: While individual tests may vary somewhat, simply most tests contain a stick that you will need to urinate on then place the stick into a sterile container. After a few moments you will read the results on the stick to determine if ovulation is imminent. Most tests indicate that ovulation is about to occur within 24 to 36 hours if a rise was detected in the LH levels.

Why: Besides just trying to get pregnant, sometimes the tests are used to determine if adjustments need to be made with certain, typically, fertility drugs or to determine whether the woman is ovulating normally and regularly each month.

Accuracy: False positives with home ovulation predictor kits are rare. Accuracy is high and in the range of 99 percent.

Potential Problems with the Test

- Irregular periods can interfere with your ability to detect the LH surge.

- Not testing daily. If you miss a day during your fertility window you may miss the surge and your ovulation time for the month.

-Drugs like birth control pills or hormone replacement therapy can lower LH readings. Anything with estrogen, progesterone or testosterone would fall into this category.

- The drug Clomid or clomiphene citrate can increase LH levels. This drug is used to trigger ovulation as a fertility drug. Testers should wait a few days after taking Clomid before testing for the LH surge.
