A Private, At-Home Approach to Conception
Designed with fertility specialists in Japan. The Prement Ring gives you a comfortable, private, and practical way to try at home — on your own terms.
Who Is Prement For?
Wherever you are on your path, the Prement Ring was designed to meet you there.
Timing & Pressure
When timed intercourse feels stressful, the Ring offers an alternative you can try at home.
Donor Conception
Using a known or clinic donor? The Ring is designed for comfortable self-insemination.
Before the Clinic
Want to try at home first? A private, lower-cost option before committing to clinical treatment.
Trying for Another
Juggling a toddler and trying to conceive again? The Ring fits into your busy life.
What Is Home Insemination?
Home insemination (sometimes called the syringe method) is a way to conceive at home, without intercourse. It's a private, low-cost option that lets you try on your own schedule.
Unlike clinical IUI, it requires no doctor's visit and no appointment. You use a device to place a sample where it needs to go — comfortably and on your own terms.
It's a practical option for many people: those managing timing pressure, those using donors, and those who want to try something at home before considering a clinic.
Why the Ring Design?
Not just a different shape — a meaningful evolution based on real user feedback.
Designed to Reduce Waste
The ring structure is designed to help minimize sample loss during transfer, addressing one of the most common frustrations with syringe-style kits.
Designed for Comfort
Soft, flexible materials and a compact form factor — built to address discomfort concerns that many first-time users experience.
Easier to Use
An all-in-one design means fewer parts, fewer steps, and less guesswork. Designed for first-time users who want simplicity.
