Highlights of Gravida
The Window of Fertility
This is the window of days in a woman’s menstrual cycle when she has the highest chance of getting pregnant..
These six days are the ‘fertile window’ in a woman’s cycle, and reflect the lifespan of sperm (5 days) and the lifespan of the ovum (24 hours).
If a woman has intercourse six or more days before she ovulates, the chance she will get pregnant is nearly zero. If she has sex five days before she ovulates, her probability of pregnancy is about 10%.
The probability rises steadily over the next 4 days until the day of ovulation when it peaks 4-6 hours from the release of the egg at 33%. This is the window which tests have not been able to accurately display until now.
At the end of this window, the probability of pregnancy declines rapidly toward 0% over the next 12-24 hours after ovulation.
Gravida...Knowledge is power
Current methods on the market lead to inaccurate tracking of ovulation:.
- Basal body temperature is useful when measured with other hormone levels, but is misleading when taken individually. Changes can happen for many other reasons and are often measured too late.
- Urine tests are highly inaccurate because by the time the Luteinizing Hormone builds up enough in the body to be detected in the urine, it is already past the optimal fertile window.
- Ovulation calendars are merely estimates of a woman’s cycle which varies from month to month.
Gravida will continuously measure all of the fertilizing hormones and basal body temperature to provide the most accurate data on a woman’s window of fertility on the market.
We guarantee a 100% accuracy of our product, which will display your own personalized ovulation cycle and fertility window in real time.• Kylie Buckner OBGYN Nurse Manager at Kaiser Permanente has approved and applauded our product saying :
"Women are in desperate need of a revolution in fertility testing like this.”
