Assisted Reproduction Gives Us More Girls than Boys

When babies come into the world naturally, we generally have 105 boys for every 100 girls. That goes to counterbalance the percentage of fatality that appears to be higher for male babies, both unborn and born.

But once artificial fertility measures are taken, a study in Fertility & Sterility reports, the number of male expectances comes down.

The study is looking into a particular reproduction technique scientifically labeled intracytoplasmic sperm injection (ICSI). ICSI is the method commonly employed to cope with male fertility problems and it is becoming more popular by day. It involves injecting the father’s sperm into the eggs extracted from the mother.

ICSI is considered very beneficial since it also serves to bring down the chances of giving birth to triplets or even more babies at a time.

But, as it turns out, blastocyst-stage embryos show a direct contrast to what we find in the natural state of things – less male babies are born.

Therefore scientists believe that ICSI shouldn’t be resorted to unless absolutely necessary if we wish to avoid the spread of this potential side effect.
