Who is Oova for?

While we currently offer two guided Oova experiences for people trying to conceive and people navigating perimenopause, there are many other reasons someone may choose to use Oova. Oova can be used to track and predict ovulation if you are navigating a reproductive health condition like PCOS, trying to optimize your diet and exercise routines through cycle syncing, and determining if certain symptoms you are experiencing are hormone-based. Doctors also use Oova to remotely monitor ovulation patterns in their patients undergoing treatments.

How does Oova work?

Oova uses innovative biochemistry to accurately measure luteinizing hormone (LH), E3G (a metabolite of estrogen), and PdG (a metabolite of progesterone) in urine. All you need to do is pee on your test strip, and then scan the test with your phone’s camera. Learn more.

How is the Oova Membership different from a one-time purchase?

The Oova Membership is a more robust fertility solution. Members can access our peer community, 1:1 consultations with experts, and member-exclusive events. Members also receive 30% off their monthly test kits.

Which hormones does Oova monitor?

Oova monitors luteinizing hormone (LH), E3G (an estrogen metabolite), and PdG (a progesterone metabolite). Tracking LH and E3G helps identify your fertile window and monitoring PdG is essential for confirming ovulation. Learn more.

Do I need to be working with a doctor to use Oova?

No - you can use Oova whether or not you are working with a doctor. If you’re not working with a doctor but are looking for expert support, the Oova Membership unlocks access to 1:1 consultations and guidance.

How is this different from other fertility apps?

Unlike apps that rely on symptoms, basal body temperature, or predictions, Oova measures your actual hormone levels in real time. This means your insights are based on your body’s chemistry, not averages or guesses.

Can I share results with my doctor?

Absolutely. Oova generates HIPAA compliant provider-ready reports that can be exported directly from the app. These reports integrate seamlessly into medical conversations, helping you get faster, personalized care. 

Is my data private and secure?

Yes. Your data is encrypted, HIPAA-compliant, and never sold. You control your information, and only you decide if or when to share it.

How does it work with my smartphone?

Each Oova strip is scanned using your phone’s camera. Our app’s AI interprets the results instantly, transforming them into clear hormone data and personalized insights.

How accurate is the test?

Oova delivers lab-grade accuracy. Our tests measure LH, E3G, and PdG with 99% correlation to blood testing in independent lab-testing, giving you the same clinical quality results from home.

Will fertility medications affect Oova's results?

Many fertility medications affect hormone behavior throughout your cycle. By measuring LH, E3G, and PdG, Oova can help your doctor determine if these changes are happening as intended.

How can I share my Oova data with my provider?

If your doctor is an Oova provider, they will receive your results in real-time. If not, you can still easily download a PDF of your results to share with them. Learn more.

What do the lines mean on an Oova cartridge?

After you pee on your LH and PdG test cartridge, you will start to see three lines develop. The top line is the control line (to see if the test is working), the middle line is PdG (a progesterone metabolite), and the bottom line is LH. The E3G cartridge has 2 lines. One for the control, and one for E3G (the urinary metabolite of estrogen). Learn more.

What do my Oova results mean?

Sometimes, interpreting your results is confusing depending on your unique hormone levels. There are several specific hormone patterns that Oova users experience more frequently. Read the guide. 

Will Oova tell me if I am in menopause?

Oova can help discover the nuances of your hormonal changes. If you're unsure if you are entering perimenopause, our product helps you to monitor your hormone fluctuations so you can identify whether ovulation is still occurring. This data can help you track and predict ovulation to help you understand your cycle even if you are entering or already in perimenopause.

Note: according to NAMS, menopause is confirmed after 12 consecutive months without a period.

Can I use Oova for TTC if I am in perimenopause?

Yes! If you're trying to get pregnant amidst hormone changes and irregular cycles due to perimenopause, Oova provides invaluable insights based on your unique hormone profile. Unlike traditional ovulation tests, our hormone-tracking system identifies your unique fertile days and confirms ovulation, even if your cycle is irregular.

Can I use Oova if I am on HRT?

Navigating the world of hormone replacement therapy (including bioidentical hormone replacement therapy) can be overwhelming. Oova is a powerful tool to monitor your hormones and track your ovulation patterns, whether or not you are on HRT. Simultaneously, your provider can remotely see your data which your doctor may use to determine what other clinical assessments and testing may be needed. Oova is not a replacement for a doctor’s hormone testing.

When do I scan my Perimenopause test strips?

For the Perimenopause Hormone Kit, you can choose to scan on your own schedule or follow Oova's guidance. We suggest scanning both an LH/PdG and an E3G test strip each day for 15 consecutive days. Depending on your goal, you may choose to begin testing once your period ends or at the onset of particular symptoms. Learn more here.

When do I scan my Fertility test strips?

The Oova app will learn about your cycle and let you know when to scan. For five consecutive days you will scan just an E3G strip. Then for 10 days you will scan both LH/PdG test strip and an E3G test strip. Finally, for five days you will scan just your LH/PdG test strips. Learn more here.

Do I need to have the Oova Test Kit to use the Oova App?

Nope - anyone can download the Oova app for free. The app can be used manually as a symptom tracker even if you aren’t testing with Oova’s test strips. Try the app.

How is Oova different from other fertility tests

Oova measures LH, E3G (an estrogen metabolite), and PdG (a progesterone metabolite) quantitatively. We use an AI-powered app to detect fluctuations based on your unique hormone baseline, not an estimated “normal”. Learn more.

Do doctors trust the results from Oova?

Oova is trusted by 100+ clinics. Oova is the only product of its kind that delivers quantitative hormone data to providers in real-time through a HIPAA-compliant clinician dashboard. Read our research.

Does Oova work for women with irregular cycles?

Yes. Oova is ideal for women with irregular cycles because we track hormones quantitatively. This means you don’t just receive a vague “positive” or “negative” result. Oova’s results are based on your unique hormone profile. Learn more.

Does Oova work for people with PCOS?

Many people with PCOS successfully use Oova. Unlike other fertility tests our AI-powered app delivers accurate results for every user by learning your unique fertility profile. Learn more. 

‍

Do I need a diagnosis or prescription to use Oova?

No. You do not need a diagnosis, prescription, or referral to use Oova. Whether you’re experiencing unexplained symptoms, managing a condition like PMOS, coming off birth control, or simply want to better understand your hormones, you can start tracking and learning from your data right away.

Can Oova help me figure out if my symptoms are hormone-related?

Oova can help you identify patterns between your symptoms and hormone fluctuations over time. By tracking symptoms like mood changes, fatigue, sleep issues, brain fog, or irregular cycles alongside hormone data, you may begin to see trends that help you better understand your body. Oova does not diagnose medical conditions, but it can provide valuable insights to discuss with your healthcare provider.

What's the difference between hormone optimization and perimenopause tracking?

Hormone Optimization is designed for women who want to better understand symptoms and hormone patterns at any stage, not just during perimenopause. It focuses on symptom tracking, hormone insights, and overall wellbeing. Perimenopause Tracking is specifically tailored to the hormonal changes and symptom patterns associated with the menopause transition.

My doctor says my labs are normal, can Oova still help me?

Yes. Many women experience symptoms like fatigue, mood changes, brain fog, irregular cycles, or weight gain even when standard lab work appears “normal.” Oova helps you track hormone patterns over time alongside your symptoms, giving you more context and personalized data to better understand what may be happening in your body and support more informed conversations with your provider.
