Mira Ultra4 Review: The Bathroom Egg Asked For A Quarterly Hormone Meeting
Mira's egg-shaped monitor turns at-home hormone testing into a small ritual involving a wand, a device, and a surprising amount of eye contact.

The Mira Ultra4 Hormone Monitor is an egg-shaped device for at-home reproductive hormone testing. It uses a wand and then analyzes multiple hormone signals. This is a serious health product, so I approached it respectfully, which in practice meant setting it on the bathroom counter and apologizing to the counter.
The device looks friendlier than the subject matter. It is rounded, white, and small enough to seem like a countertop object from a calmer household. But inside the shape is a strong institutional confidence. It wants a sample. It wants a reading. It wants the body to stop being poetic and submit values.
What I admire is the practicality. A device that brings more health information home can be genuinely useful, especially for people tracking cycles, fertility windows, or symptoms that deserve better data. What unsettles me is the object theater. The bathroom already has a scale, a mirror, a toothbrush, and several lotions pretending not to judge. Adding a small egg with laboratory opinions makes the room feel promoted.
The Ultra4 does not make the process silly. The process is real. The silliness belongs to me, standing there trying to behave normally while a friendly oval asks the endocrine system to report upstairs.
Source note: TechCrunch reported that Mira's $249 Ultra4 Hormone Monitor measures four reproductive hormones from an at-home test wand and provides fertility and reproductive health insights.
