What Reserve Tells You

Your FSH level is one of the clearest windows into ovarian reserve — helping you understand where you may be in your fertility timeline, including whether you could be approaching perimenopause.

Test across two full cycles

Six strips cover days 3, 5, and 7 of two consecutive cycles, for a clearer read than a single test.

Lab-accurate from home

Calibrated to the same ELISA standard used in clinical labs.

No appointment required

Test on your schedule, get your number in minutes.
