More > animals. We discovered that ovum, in a special environment can also control the sex of a fetus. First mechanism enables ovum to get fertilized only with sperm bearing Y- chromosome and calf of male gender is born. In second mechanism Y-chromosome bearing sperm is repelled by the ovum and only X- chromosome bearing sperm can fertilize the ovum resulting birth of a female calf. The control of prenatal sex through manipulation of an ovum is much easier as compared to the separation of X- and Y- chromosome bearing spermatozoa which are very laborious, time consuming and also unreliable. However, Through this technology we have produced 99% accurate results in the trails conducted during the period of last 12 years. The name given to this technology is “PAK SHAHPUR CHOICE SEX TECHNOLOGY”.< Less
