Chinese researchers have identified genetic mutations that cause infertility in a small number of women. Mutations in the TUBB8 gene appear to cause defects that prevent the women’s eggs from maturing properly. Scientists are not certain how many women are affected by infertility caused by persistent immature eggs, but it is thought to be rare – it has been reported to be as low as 0.1 percent of women who seek fertility treatment in China.
