Site Vis is a natural gender selection approach to choose the gender of your next baby or, if you are pregnant, to find out if you are expecting a baby boy or a baby girl.

Based on your personal biorhythms, our calendars will give you your most favorable dates to the conception of a baby boy (or a baby girl) for a period of 6 or 12 months depending of your choice. And this, regardless of your cycle. From there you'll have to identify your periods of fertility and to compare them with your dates on the calendar. When dates match then it is the right time to conceive your baby.

And if you are already pregnant, our Pregancy Calendar will help you to find out the gender of your baby.

PlanBaby calendars are to the sole use of the women and have 95% success rate. Please note that no natural gender selection method will guarantee you 100% success rate. Although and among all the natural methods, the biorhythms approach, on which our calendars are based, offers the highest success rate.
