The selection of gender has been a quest of couples for as far back as recorded history allows. It has been known for many years that the gender of a fetus at pregnancy is determined by the sex chromosome carried by the sperm, giving a sex ratio of 50:50 male versus female.
During the process of gender selection via sperm sorting, we tend to increase the chances of having a female or male child by separating sperm that bear the X chromosome (female) and those that bear the Y chromosome (male), and inseminating (via IUI) those sperm rich fractions for whichever sample is desired.
The process may be also used to balance the sex ratio in a family building situation and is thus a "family balancing" modality.
The sperm sorting procedure can be employed for couples who want to have their first child of a specific gender or wish to have a specific gender child to balance the sex ratio of their children in their family. The process is otherwise known as family balancing. Our success rate in shifting the sex ratio is approximately 85% for the male selection and 73% for the female selection.
It should be noted that this is not a guaranteed procedure, but it will definitely increase ones chances for a specific sex of a child. Gender selection does not damage or alter the sperm in any way, therefore, it will not affect the chances for any abnormalities to the fetus, the establishment of a pregnancy or the health status of the born child.
