Whoop is launching a women's health blood panel with 11 biomarkers, available next month, to provide insights into areas like hormonal transitions and nutrient levels. The company is also adding a Hormonal Symptom Insights feature to its app, which models menstrual cycles to predict periods and analyze symptoms.
These features are part of a broader industry trend of fitness wearable companies expanding services to address women's health. Whoop noted that women are its fastest-growing user segment, with engagement on its platform increasing significantly.
The main topics covered are the launch of Whoop's new women's health blood testing panel and app feature, the industry trend of focusing on women's health tech, and the growth of female users within the wearable market.
Fitness wearable maker Whoop is launching a new panel focused on women’s health through its Whoop Labs blood testing service. The company is also adding a new feature to its app that surfaces information about hormonal changes during menstrual cycles.
The startup said the panel includes 11 blood biomarkers that can give insights into aspects such as cycle regulation and hormonal transitions: Anti-Müllerian Hormone (AMH), Progesterone, Prolactin, and Thyroid Peroxidase Antibodies (TPOAb), Free T4, Free T3, Leptin, Vitamin B12 (Cobalamin), Folate, Magnesium, and Phosphate (as Phosphorus).
The company claims measuring these biomarkers will help users understand more about perimenopause, thyroid function, nutrient sufficiency, and bone metabolic resilience, when paired with data on activity, sleep, and recovery.
The test will be available to users for purchase from next month. When Whoop launched its blood testing service in September 2025, it had over 350,000 people on the waitlist.
Meanwhile, the Whoop apps’ new Hormonal Symptom Insights and Predictions feature creates a model of hormonal changes over menstrual cycles based on previous data. It uses this model to predict possible date windows for the next period, give insights into cycle lengths, period length and irregularities, and detail individual symptom patterns.
The company said it can tie insights from this feature into lab results to sort biomarker results into ‘optimal,’ ‘sufficient,’ or ‘out of range’ categories.
Whoop also released a new menstrual cycle white paper to give insights into the company’s modeling behind these new features.

Fitness wearable companies have lately been working on adding more features and services catering to women’s health to address demand from this long-underserved part of the userbase. Earlier this month, smart ring maker Oura released a new AI model focused on women’s health, along with a chatbot that would provide insights on health data and answer questions.
Whoop said on Tuesday that it saw a 150% increase in women using its products compared to a year earlier, making up its fastest-growing user segment. The company noted that women engage 30% more with its Whoop AI feature.
In October 2025, Oura’s chief commercial officer, Dorothy Kilroy, told TechCrunch that the company’s fastest-growing user base was women in their twenties.
