Ovulation prediction methods have been typically based on ovulation symptoms such as basal temperature, cervical fluid observations, or simply counting cycle days, but not on the actual ovulation triggers. With the development of ovulation tests based on lateral flow immunoassays (the same method of operation as pregnancy tests), more light was shed onto the actual date of ovulation in each cycle. These tests are not only confusing, but have made people think that a positive result means high fertility. In reality, a positive ovulation test only means that the hormones are at a high level (a peak) and ovulation is imminent. The fertile window opens 6 days before ovulation due to the extended survival time of the sperm and survival of the egg.
The Pearl Fertility Kit in combination with the Pearl Fertility App tracks and charts hormones during the cycle, and makes sure to pinpoint the ovulation date with precision and well in advance allowing for catching most of those fertile days. The Pearl Fertility kit includes tracking of the hormones responsible for ovulation: LH (Luteinizing hormone), FSH (Follicle-stimulating hormone), and Progesterone in some kits. These hormones are charted over time to predict and confirm ovulation and it is a safe way to track fertility each cycle.
The system works by exposing the test strips in the Pearl kit to first morning urine and snapping a picture of the test strip result. The Pearl App will then show a personalized fertility prediction based on the hormonal profile of the user and will chart the hormonal levels throughout the cycle. Every woman is unique and so is her cycle. Pearl also works for irregular cycles and knows that some cycles are shorter than others. The App gives information on the most fertile days and enables the user to have an overview of their entire fertile window (yes, all of it) in advance. Compared to other fertility tracking methods, Pearl actually combines traditional OPK methods with a bit of science and digital analytics to give the most accurate cycle tracking and period calculation out there. No more squinting at lines or interpreting digital smiley faces. A Pearl kit includes 15 tests for LH and 15 test strips for FSH and comes with 2 free pregnancy tests.
