Company profile

researched Aug 2026

Modern Fertility is a San Francisco-based women's health company that makes fertility hormone panels—previously available mainly through fertility clinics—accessible to consumers at home or at a nearby lab. A customer completes an online quiz, a request is reviewed and ordered by a board-certified physician, and the panel is customized based on the customer's birth control. Samples are collected via finger prick at home and mailed in, or drawn at a Quest Diagnostics location, and are processed in a CLIA-certified laboratory. Results always include AMH (described by the company as the most reliable marker for ovarian reserve) and TSH, and are interpreted against clinical thresholds set by fertility physicians.

Customers receive a personalized report explaining what their hormone levels mean for ovarian reserve, egg freezing and IVF, and menopause timing, plus downloadable levels to share with their own doctor. The company retests flagged hormones at no additional cost. Support services include one-on-one consultations with fertility nurses, weekly live webinars branded "Egginar," and an online "Modern Community" available through a free app. In the year before its 2021 acquisition, the product line expanded beyond the hormone test to a quantitative ovulation test, an early-detection pregnancy test, a cycle-tracking app and other digital fertility tracking tools.

The company stated that it also invests in its own cultural and clinical research aimed at identifying unmet needs among women and their partners and at developing better predictors of fertility, arguing that the fertile (as opposed to infertile) population is under-researched.

Founding story

Afton Vechery co-founded Modern Fertility in 2017 after her own experience seeking baseline fertility testing. Her first job after school was at a healthcare private equity fund, where she led research for an investment in a network of IVF clinics; she later moved to the West Coast to run the consumer tools division at 23andMe. When she asked her OB-GYN to order baseline fertility tests, the request was declined because she was not actively trying and failing to conceive, and she ultimately went to a fertility clinic, received a PCOS diagnosis and paid roughly $1,500 (reported elsewhere as more than $1,500) out of pocket. Discussing the experience with other women convinced her there was a widespread information gap about reproductive health, which became the premise for the company. Carly Leahy co-founded the company and served as Chief Creative Officer.

Business model

Direct-to-consumer sale of physician-ordered diagnostic test kits and related reproductive health products, supported by digital reports, a free app, community forums and nurse-led education. Testing is fulfilled through mail-in at-home collection or in-person draws at Quest Diagnostics locations and processed by a CLIA-certified lab.

Product sales to consumers. The flagship hormone test is priced at $159 (the company's own site shows $179 versus a stated ~$1,000 clinic price) and is not covered by insurance for proactive testing, though the company notes it is eligible for FSA/HSA reimbursement. Additional revenue comes from ovulation and pregnancy tests.

Traction

Reported total funding of $22 million and a team of 25 at the time of acquisition. The app community was described as having more than 10,000 members in November 2020. The company expanded from a single hormone test to a multi-product line during 2020 and was acquired in 2021 in a transaction valued above $225 million.

Latest developments

On May 19, 2021, Ro announced it would acquire Modern Fertility in a deal reported at more than $225 million. Modern Fertility was to be folded into Ro's vertically integrated telehealth, pharmacy and in-home care platform, with Afton Vechery becoming president of women's health and Carly Leahy vice president of brand, women's health. Ro had raised a $500 million Series D in March 2021 at a $5 billion valuation and had separately acquired software company Workpath.

Full profile — market position, technology, go-to-market, geography, history, risks & controversies

Market position

Positioned as an early and prominent entrant in consumer fertility testing, described in coverage as a pioneer of proactive, education-led fertility care and part of a broader wave of fertility-tech startups. Investors framed it as a potential category-defining consumer brand in women's health; Rock Health data cited in 2021 noted funding for women-focused digital health startups rose 105% in the prior year to $418 million across 22 companies.

Emphasis on proactive rather than reactive testing—offering panels to people who have not been diagnosed with infertility—at roughly one-sixth to one-tenth of quoted clinic prices; test customization for users on birth control; free retesting of flagged hormones; physician oversight and a medical advisory board chaired by Nataki Douglas, MD, PhD; and a bundled support layer of nurse consultations, webinars and an online community.

Technology

Physician-ordered, customizable hormone panels analyzed in CLIA-certified laboratories, combined with an algorithmic interpretation layer that maps self-reported data, age and hormone levels to clinical thresholds and published literature to generate personalized reports on a user dashboard. Additional products include a quantitative ovulation test and a cycle-tracking mobile app. A web-based fertility timeline tool draws on datasets compiled from clinical studies of time-to-conception and chromosomal abnormality risk by age, developed with reproductive endocrinologists and OB-GYNs.

Go-to-market

Consumer-direct online funnel beginning with an educational quiz and free tools such as a fertility timeline visualizer, supported by content marketing, press coverage (Vogue, New York Times, MobiHealthNews), founder-led storytelling, social media, weekly "Egginar" webinars and a member community that functions as a retention and referral channel.

Women and people with ovaries who are not currently trying to conceive but want baseline information for future family planning, as well as those actively tracking cycles or trying to conceive; the company also markets to users on hormonal birth control and to people with irregular cycles or PCOS.

Geography

Headquartered in San Francisco, California, serving customers in the United States through mail-in at-home collection and Quest Diagnostics lab locations; customer support operates Monday–Friday, 9am–5pm PT.

History

Founded in 2017 in San Francisco, Modern Fertility went through Y Combinator's Summer 2017 batch. It announced a $15 million Series A led by Forerunner Ventures in June 2019, bringing total disclosed funding to $22 million from Forerunner Ventures, Maveron, Union Square Ventures, First Round Capital, Box Group, #Angels and Y Combinator. Through 2020 it broadened its catalog from the hormone test to ovulation and pregnancy tests and a cycle-tracking app. In May 2021, digital health company Ro announced an agreement to acquire Modern Fertility in a deal reported at more than $225 million; both co-founders moved into leadership of Ro's women's health vertical. Y Combinator lists the company's status as acquired and its team size as 25.

Risks & controversies

Proactive fertility hormone testing is not covered by federal insurance, and in some states reactive infertility testing is only covered after a year of unsuccessful attempts to conceive, limiting reimbursement pathways. The company itself states that a hormone test alone cannot diagnose a condition and that its timeline tool is not a predictor of fertility. Sources note a broader debate about employer-funded egg freezing being criticized as a way to keep employees working longer without families, though this is not specific to Modern Fertility.
