What May Health does
May Health is a privately held medical device company developing the Anavi System, a transvaginal ultrasound-guided radiofrequency ovarian ablation platform intended to restore ovulation in women with polycystic ovary syndrome (PCOS)-related infertility who have not responded to first-line ovulation induction therapies such as letrozole or clomiphene citrate. The system comprises three integrated components — a Therapy Needle, a Needle Guide, and a custom Radiofrequency Generator with temperature control — and is positioned as a one-time, office-based, non-hormonal procedure that avoids the general anesthesia and hospital setting required by traditional laparoscopic ovarian drilling. The technology is protected by eight granted US patents and is reinforced by trademarks covering the Anavi and "Ovarian Rebalancing" brand identities.
The company operates with dual headquarters in Menlo Park, California and Paris, France, reflecting its origins in the Paris-based MD Start medtech accelerator (under the predecessor names Ziva Medical and AblaCare SAS). May Health secured CE Mark certification under the EU Medical Device Regulation in October 2025, enabling European commercialization, and is concurrently enrolling the REBALANCE pivotal Investigational Device Exemption (IDE) trial across more than 15 US fertility centers to support FDA marketing authorization. Its target customers are reproductive endocrinology and infertility (REI) practices and fertility clinics.
May Health's business model is structured around hardware sales of the Anavi System to fertility clinics and reproductive endocrinology practices, with potential recurring revenue from disposable procedure components. The company is pre-commercial, generating no product revenue to date; monetization depends on European launch following CE Mark and on US entry contingent on FDA approval. The company has raised approximately $36.7 million across disclosed rounds, backed by Sofinnova Partners, Trill Impact, Bpifrance, and most recently Nexpring Health, and is led by CEO Colby Holtshouse (appointed March 2025).
