Fitness clothing manufacturer Cry 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 presents information about hormonal changes during menstrual cycles.
The startup said the panel includes 11 blood biomarkers that can provide insight into aspects such as cycle regulation and hormonal transitions: anti-Müllerian hormone (AMH), progesterone, prolactin, thyroid peroxidase antibodies (TPOAb), free T4, free T3, leptin, vitamin B12 (cobalamin), folate, magnesium and phosphate (as phosphorus).
The company says measuring these biomarkers will help users better understand perimenopause, thyroid function, nutrient sufficiency and bone metabolic resilience, when combined with activity, sleep and recovery data.
The test will be available for users to purchase starting next month. When Whoop launched its blood test service in September 2025there were more than 350,000 people on the waiting list.
Meanwhile, Whoop apps’ new hormonal symptom analysis and prediction feature creates a model of hormonal changes during menstrual cycles based on previous data. It uses this model to predict possible date windows for the next period, provide insight into cycle length, period duration and irregularities, and detail individual symptom patterns.
The company said it can link information from this feature to lab results to sort biomarker results into “optimal,” “sufficient” or “out of range” categories.
Whoop also posted a new white paper on the menstrual cycle to provide insight into the business modeling behind these new features.

Fitness clothing companies have recently been working on adding additional features and services aimed at women’s health to meet demand from this long-underserved part of the user base. Earlier this month, smart ring maker Oura released a new AI model focused on women’s healthas well as a chatbot that would provide information on health data and answer questions.
Whoop said Tuesday that it has seen a 150% increase in the number of women using its products compared to the previous year, which is 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 20s.
