Biotech company 23andMe is very open about the fact that it offers your genetic data from its DNA test kits to researchers -- with your consent, of course. Now, its contribution to a genetic study about polycystic ovary syndrome (PCOS), a common cause of infertility in women, has paid off. The study conducted by researchers from the University of Cambridge and other institutions has revealed more pertinent information about the disorder. Out of the 200,000 women whose information were used, 87,000 were 23andMe customers. A total of 5,000 women from the customer pool have the condition, while the rest don't and were used as control.
