A New Approach to Understanding Hormones: The Egg-Shaped Innovation

Your urine can reveal significant insights into your reproductive hormone levels. Historically, home testing has been a challenging task, often requiring samples to be sent to laboratories. The health tech startup Mira aims to change this with its Ultra4 Hormone Monitor, priced at $249.

This device offers users a precise and easily accessible way to test hormones at home. It actually comprises two separate pieces: the first is the egg-like Hormone Monitor that interprets the test results. The second component is the Ultra4 Wand, a stick designed to test four specific reproductive hormones: follicle stimulating hormone (FSH), luteinizing hormone (LH), estrone-3-glucuronide (E3G), and pregnanediol 3-glucuronide (PdG).

Comprehensive Hormonal Insights

Testing all four hormones simultaneously allows users to not only examine their fertility status but also understand various health conditions such as polycystic ovary syndrome (PCOS), premenstrual dysphoric disorder (PMDD), perimenopause, menopause, and even aspects of metabolic health. Sylvia Kang, Mira's CEO and cofounder, believes that routine home checks can help tailor treatments and detect trends in hormone levels over time.

Kang recalls that, back in 2018 when Mira was established, such home-based hormone evaluations were unheard of. Observing friends encountering difficulties conceiving later in life drove the creation of this product, as standard options like ovulation kits lacked precision and deep insights.

Breaking New Ground in Wellness

Interest in hormonal wellness has surged recently, and though influencers have drawn attention to it, there's a broader recognition of the challenges in addressing hormonal health. Despite Mira's longstanding presence, the Ultra4 kit became more accessible after its initial release in late August, expanding its reach since its showcase at CES 2026.

Users start by completing a detailed questionnaire on the Mira app to set their testing goals, which could include understanding fertility windows or managing hormone levels. The process involves urinating into a provided silicone cup and inserting a test stick, which after a brief wait is placed into the analyzer for results.

While early outcomes are pending, an individual test could potentially reveal insights into menstrual health, egg reserves, or underlying causes of hormonal fluctuations. My personal plan advised testing over a couple of cycles to detect perimenopause signs, illustrating that the device's utility unfolds over time.

Not a Birth Control Device

Although Mira is not suited for birth control, it serves as a wellness device. It holds an FDA Class I designation, implying minimal risk and less stringent regulatory oversight compared to more complex medical devices.

Presently, user focus has broadened beyond just fertility issues. According to Kang, 40% of users are not seeking conception support but rather focusing on menopause, PCOS, and general hormone health, with an emphasis on symptom alleviation.

Future ambitions include expanding hormone tests to other fluids like blood or saliva and aiming for applications beyond reproductive health to general wellness and longevity pursuits. Some research even suggests links between hormones and metabolic disorders.

Cost Considerations and Industry Trends

Though a significant investment — with the Ultra4 kit starting at $249 and additional wands costing $99 — this aligns with broader shifts in health tech. The pandemic era hastened telehealth adoption, as seen with companies like Withings and Oura, indicating a growing market for at-home health management solutions.
