Thanks

AREITOSOFT  iOvulate Calculator is not a charting program. BBT and FAM charting are no covered by this program.

We at AreitoSoft are working on a solution that cover those two methods.

Thank you all for your comments and support.

AREITOSOFT  You are absolutely right, Dombett, it's aimed to the "looking to conceive" market.

AREITOSOFT  The gender selection calculation is based on the Shettles Method which is based on the premise that sperm carrying the X and Y chromosomes have different characteristics and that you can influence the reproductive environment to favor one or the other.

It is the sperm that fertilizes the egg that will determine the sex of your baby. Some sperm carry the X-chromosome and some sperm carry the Y-chromosome. If an X-chromosome-carrying sperm fertilizes the egg, the baby will be a girl. If a Y-chromosome-carrying sperm fertilizes the egg, the baby will be a boy.

The idea behind the Shettles Method of sex selection is based on the premise that the X and Y chromosome carrying sperm have different characteristics and that under different circumstances either X- or Y-chromosome-carrying sperm will be more likely to fertilize the egg.

The Y-chromosome-carrying sperm are said to:

* be faster and smaller than the X-chromosome carrying sperm.

* die faster than the X-chromosome-carrying sperm.

The X-chromosome-carrying sperm are said to:

* be slower than the Y-chromosome carrying sperm.

* be better able to withstand the acidic cervical environment before fertile cervical fluid is produced.
