Dinking girls sperm
A new chemical treatment that can segregate male and female sperm could one day mean parents going through IVF could choose whether they have a boy or girl. In experiments with mice sperm, scientists found they could produce litters that were 90 per cent male, according to the study published in Plos Biology. When the slower sperm were used, litters were 81 per cent female. The X chromosome has many genes while the shorter male Y chromosome has fewer, and this difference in gene expression meant scientists could distinguish between the two. The process — which could be simple and cheap to carry out — does not damage the DNA of sperm and could greatly simplify sex selection for IVF or artificial insemination, which is used in livestock, scientists say.
