About Kouros Health

Men deserve better fertility healthcare.

We make men's fertility health proactive, understandable, and private — while building toward broader reproductive, sexual, and preventative care.

Portrait
Clinical roots

Built with trusted urologists and male fertility doctors.

Everything we build is shaped alongside urologists and male fertility specialists who understand the gaps in men's care firsthand — delayed testing, unclear results, and limited guidance. Their perspective helps Kouros Health connect private at-home testing with responsible interpretation and practical next steps.

Why we started

Led by brothers, on a personal mission.

Kouros Health is led by brothers who are actively searching for better ways to make men's fertility open and approachable — because the silence around it is the biggest barrier of all. We are building the conversation we wish we had started earlier: calmer, clearer, and well before it becomes urgent.

Clinical judgement on one side, a founder's personal stake on the other — that combination is what we are bringing to men's reproductive healthcare.

Clinical leadership

Clinical leadership built around men’s health

Kouros is being built alongside physicians with deep experience across urology, men’s health, fertility, sexual health, and complex clinical care. Our medical leadership helps ensure that our testing strategy, patient experience, educational content, and care pathways remain grounded in evidence-based medicine.

Why We Exist

Men have historically been underserved and under-involved in fertility and reproductive healthcare. We're building the platform that changes that.

Fertility-First

Kouros begins with fertility — the life stage where men have been underserved the longest — and builds a longitudinal health relationship from there. This is a modern health platform for men who want to understand their fertility and reproductive health before there is a problem, not a clinic you visit once something has gone wrong.

Our Approach

Private at-home testing is the starting point. Clinical interpretation, personalized recommendations, expert support, and ongoing monitoring turn results into informed next steps.

Medical Quality

Clinical oversight sits with urologists and male fertility doctors — from sample handling and laboratory standards to how results are interpreted and explained. You receive clear, honest guidance on next steps, never a diagnosis from a number on a page.

Privacy

Your account and results are viewable only by you. We follow industry practices for protecting sensitive information.

The Future

Ongoing fertility monitoring, fertility preservation, sexual health, and broader preventative men's health — built on a baseline you understand and own.

Privacy & Data Handling

Your information stays yours.

Fertility data is sensitive. Here is exactly what happens to your sample, your results, and your contact information.

Your sample

Collect at home and return it in the prepaid, discreet packaging we provide. It is processed by a licensed laboratory partner using barcoded, standard-chain-of-custody workflows. Your sample is used only for the testing you requested unless you separately opt in to anything further.

Your results

Results are reviewed by an independent licensed clinician before being released to your private account. They are viewable only by you, and you control whether — and with whom — you share them.

How we use your email

Your email is used to confirm your waitlist spot, share product updates, and send fertility and reproductive health education you can act on. We never sell your email, and you can unsubscribe from any update with one click.

Data security

We encrypt data in transit and at rest, restrict access to need-to-know staff, and follow industry practices for protecting sensitive health information. You can request account or data deletion at any time by contacting us.
