Best Ovulation Predictor Kits

If you think procreation is just fun and hyperactive intimacy, you might want to think again. Several couples are facing difficulties having a baby. Is it really so difficult?

Basically, a woman gets pregnant when sperm reaches the egg. But it’s not that easy. Women are only fertile for a few days in a month and it is only then that the sperm will be able to fertilize the egg.

If this short fertile period is missed, the woman will have to wait for her next fertile period to get pregnant.

Predicting whether you are fertile or not is tedious and can be very frustrating, especially when your cycles are very long or irregular. Women’s ovaries do not have a notification that will tell them, “Hey! I just produced an egg.”

Having sex every day to get pregnant is not always the best solution. If there is no egg available, it would just not make sense at all.

And trying to conceive every day can be physically tiring, not to mention that both partners might have busy, everyday responsibilities.

For the sake of convenience, many couples find using an ovulation predictor kit very effective in determining their fertile period. With an ovulation test, a couple can know when it is best to have to have intercourse to increase their chances of pregnancy.

How an Ovulation Predictor Kit Will Help You Get Pregnant

An ovulation predictor kit is a device that determines whether a woman is fertile or not. Many women use other methods to know their fertile periods, such as using a calendar (counting days of the menstrual cycle) or charting their basal body temperature.

Though these methods are effective, they can be tiring and not preferred by couples who have busy schedules.

Many women find an ovulation predictor kit to be an effective tool to help track their fertile period. When a woman is fertile, her body secretes luteinizing hormone.

An ovulation predictor works by detecting the presence of this hormone in the woman’s urine. Most ovulation predictor tools work this way; some detect estrogen.

An ovulation kit will indicate a positive on its display if luteinizing hormone is detected. Once you get a positive test, you have intercourse, as a positive test is an indication that ovulation will happen soon.

The Best Ovulation Predictor Kits

The effectiveness of ovulation predictor kits is very important to couples. That is why many companies have produced fertility monitoring kits to supply the growing demand.

There are several brands on the market and although they all use the same concept, i.e. detect the luteinizing hormone surge, their sensitivity and accuracy rates differ, with some brands having an accuracy rate of 99%.

There are two types of ovulation predictor kits: those that detect luteinizing hormone in urine and those that measure the presence of the hormone in saliva.

For test kits that require a urine sample, these are used in the same way as pregnancy tests. If a kit indicates positive (YES+), then expect to ovulate after 12 to 36 hours. For some kits, results are displayed as lines, with the test line darkening as you approach ovulation.

A saliva-based test is more complex to use and requires that you examine a sample of your saliva under a small microscope, which typically comes in the kit. You are expected to see a ferning, crystal-like pattern if you’re ovulating.

When picking an ovulation predictor kit, it is best to check the features of the product. Below is a comparison of the best kits available at online and local stores:
