Frequently Asked Questions

What is Oova?
Oova is a diagnostic test that measures two hormones - luteinizing hormone and progesterone - from daily urine samples. With the use of the smartphone app, Oova is able to track your hormone levels over time and learn your personal fertility profile to make recommendations on your most fertile days and confirm ovulation occurred within a particular cycle.

Is Oova right for me?
If you have irregular cycles or regular cycles, then Oova is right for you. Oova aims to learn each woman’s personal fertility profile allowing for it to work for all women.
How is Oova different from period tracking apps?
Oova measures two hormones to detect what is happening throughout your menstrual cycle and recognize when you’re entering your fertile window in real-time. Oova allows you to track similar traits as the other apps but combines that with hormone measurements to learn your personal fertility profile.

How many test strips comes in one kit?
Each kit comes with 15 disposable test strips which is sufficient for a single cycle (one month).

What hormones does Oova measure?
Oova measures two key fertility hormones - luteinizing hormone and progesterone.

What is luteinizing hormone?
Luteinizing hormone, or commonly referred to as LH, is involved in many processes including pregnancy and ovulation. During a typical menstrual cycle, LH levels increase or decrease at various points. LH levels increase when an egg is about to be released from the ovary, a process called ovulation.

What is progesterone?
Progesterone is a critical hormone to measure to ensure an egg was released during a given menstrual cycle. If an egg was released, progesterone levels will start to increase. If an egg was not released, progesterone levels will remain low. It's important to track how progesterone levels are behaving to ensure you're ovulating during your cycle, especially if you are trying to conceive. Oova measures a progesterone urine metabolite, pregnanediol-3-glucuronide.


What happens if I don’t use the first urine after my longest sleep?
You may get unexpected results. Test as soon as you can after you wake up. If you wake up multiple times in the night, we recommend using your first urine for when you wake up for the day and not try to do this in the middle of the night. It's important to get a good nights sleep!

Should I test at the same time on each day of my scanning window?
We recommend to take an Oova test at approximately the same time during your scanning window to ensure your hormones are being tracked accurately. This means don't test in the morning one day and then in the evening the following day. 

How do I provide a urine sample on the sample pad?
A urine sample can be provided in one of two ways. 1) You can collect your urine in a cup and dip the sample pad into the sample for 5 seconds. Make sure you do not dip so far that the QR code is coming in contact with the urine. 2) You can provide a sample midstream. Click a cartridge onto the included handle. Before providing the sample, flip the handle over so the result window and QR code are facing down and away from you. The sample can be provided directly on the sample pad for 5 seconds.

What do the lines on the test strip mean?
Each Oova cartridge will display one, two, or three lines. The top line (furthest away from the QR Code) is the control line. This line informs you that the test worked. The second line is the test line for progesterone. This line gets LIGHTER the more hormone present in the sample. The third line is the test line for luteinizing hormone. This line gets DARKER the more hormone present in the sample. 

I’ve not seen any High Ovulation days. Why is this?
It may be that your LH levels are not exceeding your baseline as much as expected. You may still see Peak Ovulation without a reading of High Ovulation. Oova is learning your hormone trends every day and will get smarter from the data collected this month.

I have not seen any Peak Ovulation days. Why is this?
Your LH surge may not be exceeding your baseline as much as expected or you may not have ovulated this cycle. This is not unusual but we recommend you see your physician if you do not see Peak Ovulation for three consecutive cycles.

What do the hormone percentages mean?
Every time you use an Oova test, you will be provided with your hormone levels for both LH and progesterone. The levels will be displayed as a percentage. The percentage is calculated by taking the measured value on the test and dividing by the highest measurable amount for each hormone, multiplied by 100. For LH, the highest measurable amount is 125 mIU/L. For progesterone, the highest measurable amount is 22.5 ng/mL. Please note, if you are working with a clinician that is an Oova provider, they will see your actual hormone values in their clinician dashboard.

Why did my scanning button disappear?

In order to learn your personal fertility profile, we need to ensure we capture enough data each cycle. If your scanning button has been removed, it may have been for one of the following reasons:

  1. We were unable to capture enough data to effectively measure your baseline hormone levels. This information is critical for us to monitor you LH surge and increase in progesterone.
  2. Too many days were missed in this cycle's scanning window for us to accurately understand what is happening your cycle. Oova is designed to be used for 15 consecutive days. If too many days of the 15 are missed, our algorithm will be unable to learn key nuances present in your cycle.

In any case, we recommend you hold on to your remaining strips and continue using Oova in your next cycle. Be sure to accurately log your period so Oova can inform you of when your scanning window begins.

Can medical conditions affect the results?
Certain medical conditions can impact your results, for example, if you are pregnant or have recently been pregnant, have reached menopause, have impaired liver or kidney function, or are taking fertility drugs. Let us know if you have any of these conditions within the app under Settings > My Profile > Reproductive Disorder so our algorithm can help you get smarter about your fertility.

Will certain medications affect the results?
Oova will be helpful while going through various medical treatments as it can confirm that the medications are working in the intended way. Many medications impact hormone behavior to induce ovulation or other key moments in your cycle. By measuring LH and progesterone, Oova can determine if these changes are happening as intended. 

Can Oova be used during pregnancy?
Oova can be used to monitor a pregnancy early in the first trimester, specifically if interested in tracking progesterone levels. If pregnant, progesterone levels should surpass what Oova can monitor however, it can alleviate some stress to ensure progesterone levels remain elevated.

Can Oova be used as a contraceptive?
All of the testing that has been done to date has been to optimize a chances of conception. If a couple chooses to use Oova as a contraceptive, it would be an off-label use. 

How do I dispose of the cartridge?
When you have finished using a cartridge, eject the cartridge from the holder and dispose of it in your regular garbage bin.

I’ve used OOVA for several months and haven’t become pregnant. Why is this?
It can take normal healthy couples many months to achieve a pregnancy. We recommend that you see your physician if you are under 35 years and haven’t become pregnant after trying for 12 months. If you are over 35 years you should see your physician after trying for 6 months, and if you are over 40 years see your physician right away.

Once I get a High Ovulation or Peak Ovulation result, what should I do?
If you are trying to get pregnant, you should start having intercourse! You are most likely to get pregnant if you have intercourse within 24-36 hours after you get a High Ovulation result.
