Reproductive health app Glow now allows men to track factors affecting their fertility and link with partners' accounts
An App for Hacking Fertility Now Also Works for Men — In our culture, reproduction is often seen as women's work. From pregnancy to childbirth through nursing a newborn child …
Context & Ripple Effects
In April 2015, Glow widens its fertility app beyond women, letting men log factors affecting their own fertility and link their accounts to a partner's. Two months later, Apple added reproductive health categories to HealthKit, signaling that the platform layer was ready to treat fertility as mainstream health data rather than a niche women's feature.
First-order effects
- Men become direct Glow users rather than bystanders, and the partner-linking feature consolidates two people's reproductive data into connected accounts — one profile per couple instead of one per woman.
Second-order effects
- Linking accounts enlarges each user's exposure surface: when a bug later exposed the personal data of roughly 25 million people through Glow's online forum, the fix took about a week, showing how much sensitive material a shared-account design concentrates in one system.
Third-order effects
- Fertility apps evolve into couple-scale health platforms whose data-sharing practices attract regulatory-grade scrutiny — from researchers alleging Premom shared data with third parties without consent to post-Roe fears that period-app records shared with partners or affiliates could become criminal evidence.
The trend: Consumer fertility tracking is expanding from a single-user, women-focused tool into a couple-linked health platform whose aggregated data becomes both its product advantage and its central liability.
