Meet Pearl powered by Proov.
Pearl turns your iPhone into a powerful fertility tracker. Pearl works by monitoring your hormones daily to give accurate fertility predictions. Pearl is the only system to measure 3 fertility hormones – FSH, LH, and progesterone – giving you a more complete understanding of your cycle and your hormones.
Pearl powered by Proov measures 3 key fertility hormones.
Follicle Stimulating Hormone (FSH) – the blue strip – FSH levels are high in the beginning of the cycle and decrease once a follicle is selected and starts to develop. Pearl tracks the decrease in FSH levels and uses this information to open your fertile window.
Luteinizing Hormone (LH) – the pink strip – Once the follicle is ready, a surge of LH is released and ruptures the follicle and release the mature egg inside, also called ovulation. Pearl tracks changes in LH levels and uses a surge in LH to predict ovulation date.
Progesterone (PdG) – the purple strip – Progesterone is produced from a follicle after it ruptures and releases an egg (Ovulation). An LH surge doesn’t always result in ovulation. To confirm ovulation has indeed occurred, Pearl tracks increases in the urine metabolite of progesterone (PdG) to confirm ovulation date.
