Baby Gender Predictor 2010 is simple but useful software to predict the sex of a baby by using three different methods: Chinese, Japanese, and Blood Age methods. The Chinese method is related to the lunar calendar, and the only data you enter is the mother's birthday and conception date. The Japanese method uses the mother's birthday, the father's birthday, and the conception date to determine the gender. Finally, the Blood age method is the one that needs more data to make the prediction. It requires the mother's birthday, the father's birthday, the conception date, and the mother blood rhesus-factor. In the three methods, the data can be easily entered by selecting it on a calendar that opens when you click on the different fields. Once you entered the necessary information, you press the Predict button, and the result will be displayed on the right showing a picture of a boy or a girl.
The application has a very intuitive and attractive user interface, which is also available in Russian and can be used by anyone.
In short, I really don't know if these three methods are effective for determining the gender of a baby, but the program is completely free and simple, so I suggest you try it and see yourself.
