The Vivoo FlowPad turns menstrual pads into an at-home hormone test

Wellness tech companies are increasingly willing successful bodily fluids for illustration blood, urine, sweat, and saliva. At CES 2026, it’s clip to adhd menstrual humor to that list, too. Health tech startup Vivoo conscionable announced the FlowPad, a astir $4 to $5 menstrual pad that doubles arsenic an at-home hormone trial for follicle-stimulating hormone (FSH). Users will beryllium capable to either position the results straight from the pad aliases return a image pinch the Vivoo app to get much insights.

“We started arsenic a vaginal pH search liner for your panties that would alteration colour pinch vaginal discharge,” Vivoo CEO and cofounder Miray Tayfun tells The Verge. “It’s evolved into a play pad pinch microfluidic channels that seizure blood, and nether the pad, there’s a model that shows your FSH levels.”

Tayfun says the use of integrating a hormone trial into a pad is it’s a hygienic merchandise that menstruating group already use. The challenge, however, is that humor tends to barren quickly. In different blood-based at-home tests, Tayfun explains, users often person to dilute the sample pinch a solution. To embed this benignant of trial into a pad, Vivoo had to replicate that process successful a bladed yet wearable design.

The pad itself has 2 layers. One is simply a “capillary seizure layer” that draws successful the humor and filters retired particulates. A 2nd “biomarker guidance layer” has stabilized reagents that interact pinch the humor to observe FSH. So, essentially, you spell astir your day, bleed into the pad, and erstwhile it’s clip to move out, position your results. The results are shown connected the backmost of the pad successful a windowed area, which you tin spot successful the image above. It resembles a gestation aliases covid-19 test. High levels of FSH tin bespeak little ovarian reserves, fertility issues, aliases conditions specified arsenic polycystic ovary syndrome (PCOS).

“The main extremity present is to make 1 hygienic pad little than $5, truthful a play won’t costs you much than $30,” says Tayfun, noting that the Vivoo squad was alert of really costly sanitary products tin be. “It doesn’t person to beryllium a everlastingly product.”

While personification could usage the pads for each time of their cycle, Tayfun says it’s meant to beryllium worn connected the 2nd aliases 3rd day. Depending connected what the personification is looking for, it could beryllium worn for a fewer months continuously aliases intermittently. So far, Vivoo estimates pricing astatine $4 to $5 per pad, pinch the anticipation of subscription and battalion configurations erstwhile the merchandise is person to launch. At first, Tayfun says the institution will beryllium rolling retired entree to researchers, aesculapian partners, and existing Vivoo users.

The thought is for menstruating group to study thing from their FSH levels, which tin beryllium an parameter of fertility levels, irregular cycles, and hormonal patterns. That could beryllium useful for group hoping to get pregnant, dainty hormonal conditions for illustration PCOS, aliases those who fishy they whitethorn beryllium entering perimenopause, the transitional clip betwixt a person’s fertile years and menopause. Tayfun says the perfect personification is personification successful their 30s to astir property 45.

The FlowPad isn’t the first clip we’ve seen menstrual tech. A mates of years ago, we covered Emm, a smart menstrual cup that contained biosensors to way travel and summation reproductive wellness insights. At-home hormone search devices and kits besides look to beryllium gaining traction arsenic much group bargain into wellness trends of “balancing hormones.”
