The baby's gender calendar will help parents plan the desired gender of their future baby. The calculation is based on the date of ovulation and the possibility of conception with X- or Y-spermatozoa. If the X-spermatozoon merges with the egg, a girl will be born, and if the Y-sperm is a boy will be born. Unfortunately, it is impossible to influence this process or completely to foresee it. Our calculator will give an opportunity only to determine approximately the most favorable days for planning the desired gender of the baby. Calendar can not guarantee the birth of a child of a planned sex with 100% probability! If you have an unstable cycle or change the date of ovulation, then the accuracy of calculations decreases. The calculator will calculate for 6 months - the average period of the child's planning.
