Ovulation Time

With OV-Watch’s Advanced Technology, you will get Advanced Notice of your individual ovulation time.

It is a common misconception for couples trying to conceive that they should only have intercourse during the ovulation time. It is true that the time of ovulation is when the sperm fertilizes the egg for conception; however, the day of ovulation is not the only day that is considered “fertile”. According to several published medical articles, the highest probability of conception occurs with intercourse on the days prior to ovulation, rather than the day of ovulation itself.2,3 Most health experts believe a woman’s cervical mucus is at its most fertile stage in the days before ovulation1. And since sperm is reported to live for 6 days in the genital tract4, having intercourse on those four days before ovulation may hold a woman’s highest probability of conception for that month.

Studies Relating to Ovulation Time

Using urine strips and charting temperature to identify when you are ovulating can be messy, inconvenient, and may lead to inaccurate results. Urine testing for the LH surge may miss ovulation in up to one third of women.10,11 A woman’s LH surge is detected in the urine  only 12-24 hours before ovulation.  Sandra Ann Carson, the President of the American Society for Reproductive Medicine is quoted as saying, “Although LH peaks accurately detect ovulation, they do not identify the pre-ovulatory fertile period. Up to two thirds of pregnancies are conceived at or prior to ovulation.”⁴   Basal Body Temperature (BBT), or charting your temperature, lets you know after you have ovulated. Recent evidence shows that “no conception has ever been documented on the day after ovulation”³. In a study published in the New England Journal of Medicine, in a series of 221 patients, a total of 625 menstrual cycles were followed in which women had natural intercourse during natural cycles.¹ There were no pregnancies when intercourse occurred the day following ovulation. The unfertilized egg, only has a life span of approximately 12-17 hours, but may only be optimal for only 2-6 hours.⁵

Knowing the 4 days before ovulation time leads to the highest probability of pregnancy.

If you use OV-Watch fertility predictor, you will be able to find the 4 days before ovulation as well as the day of ovulation- your full fertile window. OV-Watch detects the chloride surge. That surge comes 6 days before ovulation. It is an earlier indicator of ovulation than LH urine testing. When OV-Watch detects the chloride surge, it will clearly alert you to fertile days 1 through 4 and ovulation day.
