I spent years telling women what to expect. Then it was my turn.

For most of my working life I have been a urogynecologist. The women who come to my office are usually there about something they have not told anyone else.

Often it is a dryness that started quietly and never left. Sometimes it is a bladder that wakes them at three in the morning. Over the years I have sat through thousands of these visits, and every woman arrives with her own version of it. Still, the thread running through most of them is the same: something changed around perimenopause or menopause, and nobody had warned her how much it would change.

I knew the textbook answers, and I prescribed them. Some helped. Others were off the table for the woman in front of me because of her history, or she did not want them. I referred many patients to clinic treatments that cost more than a month of rent, and I watched others decide to live with it instead.

Then it was my turn. I was in my late forties and I recognized every symptom I had been describing to other women for years. Understanding it as a doctor turned out to be very different from lying awake with it.

So I started sketching. I had read the research on red light for tissue and on blue light for the surface environment, and I had seen in practice what gentle warmth does for comfort. What I could not find was a single device that put those together in a shape a woman with sensitive tissue could use at home, without a prescription. I decided to build one.

It took two years to get a working prototype. I am a physician, not an engineer, and I lost count of how many versions ended up in a drawer. The one that finally worked took another full year of tuning: how warm is warm enough without being too warm, how much red light actually reaches the tissue that needs it, how the vibration should feel, and how long a session should run before the device switches itself off.

I tested every version on myself first. When I was satisfied, I offered it to women who were already coming to me with the same complaints. They told me what felt good and what did not, what they used every week and what they ignored. The slimmer head, the rounded tip, the three plain buttons, the ten-minute timer: all of that came out of those conversations.

Renew is the device I wish I could have handed to every woman who sat across from me and asked, "Is this just how it is now?"
