Choice
Hormone-free contraception · In development

An on/off switch for fertility.

Every child desired.

Choice is a tiny valve implant, placed in each fallopian tube in an outpatient procedure through the vagina and cervix. Closed, it is designed to keep sperm and egg apart, ensuring conception is not possible. Opened, it is designed to let fertility return. No hormones, no care, no maintenance.

Investigational device. Not approved or available for use in any market.

01Why
121 million

unintended pregnancies, every year.

Nearly half of all pregnancies worldwide. Many women want contraception that is always there, without hormones or chemicals. Today only sterilisation meets those needs, and it is hard to undo.

Choice is built around one idea: contraception you can switch on or off, the day you decide to.

02How it works

Placed once. Switched when you choose.

01

Placed through the cervix

In an outpatient procedure, with a dedicated endoscope. No incisions, and specifically designed to be placed and removed without pain.

02

Closed without power

The valve is bistable: it stays closed on its own. Designed to keep sperm and egg apart, so that conception is not possible.

03

Opened when you want

Switched open in a short procedure. Designed to let fertility return, and to be removable.

03Progress

Where Choice stands today.

A medical device earns trust one study at a time. We publish what has been shown, and what has not been shown yet.

Largely doneLab and preclinical

Valve, materials and placement tested in the lab, in tissue models and in animals.

Starting 2026First studies in women

Placement studied in women already scheduled for a hysterectomy.

PlannedPilot study

At least 50 women, at several centres.

PlannedPivotal study

500 to 1,000 women, in Europe and the US.

Target 2031–2032Approval and launch

FDA approval targeted for 2031, market introduction in 2032.
