The most important discovery that allowed the development of the semen sexed technology is that X-chromosome-carrying sperm (female sperm) contains 3.8% more DNA than Y-chromosome-carrying sperm (male sperm).
For Electa, Intermizoo chose IntelliGen technology, which use a detection laser to determine the sperm’s chromosome. By using specific molecules that cause fluorescence, the male sperm is distinguished from female sperm, which appears more brightly colored due to the 3.8% extra DNA.
Once the Y-chromosome sperms (male) are identified, they are inactivated using a second laser that separates the sperm’s head from its tail, making them immobile and unable to fertilize.
This process ensures minimal stress for the female sperm, resulting in an excellent final semen quality.
