MicroSort Sperm Sorting

The only clinically proven method for separating X sperm and Y sperm

Sperm SortingMicroSort is a technique for separating the two types of semen found in sperm, X sperm and Y sperm. An XSort increases your chances of conceiving a girl to about 91%, and a YSort boosts your odds of conceiving a boy to about 76%.

The MicroSort Theory

Very simply, the theory behind MicroSort is that if a woman gets pregnant with semen that contains mostly X sperm, she will most likely conceive a girl; or if she gets pregnant with semen that contains mostly Y sperm, she will most likely conceive a boy. MicroSort results have in fact proven this theory: the X:Y ratio in sperm directly corresponds to the odds of conceiving a girl or a boy. In the race to conception, the side with strength in numbers usually wins the day.

The MicroSort Process

MicroSort Process

This is a very general idea of the MicroSort process. A semen sample is separated in the MicroSort sperm sorter using a technique called flow cytometry. An XSort results in mostly girl-producing X sperm, or a YSort results in mostly boy-producing Y sperm. The sorted sample is then used to get pregnant, either by artificial insemination (IUI) or in-vitro fertilization (IVF).

The sorting process isn't perfect. After an XSort, on average, 10% of the sorted sample will consist of unwanted Y sperm. After a YSort, on average, 24% of the sorted sample will consist of unwanted X sperm. This means that although your odds of having the desired gender have been drastically and reliably improved over nature, it is still possible to have an opposite. And although this is uncommon, yes, it does happen.
