A study of 3,000 women in Austria has found that women who were born during the summer months have less children than women born in other seasons. The study was published last Thursday and run by the University of Veterinary Medicine in Vienna.

Dr. Susanne Huber, from the University, said that "We found that the women born in July had 0.3 fewer children per woman than those born in December, or to put it another way, 13.4 percent fewer of the 2.24 mean number per women overall."

The study supports earlier research which stated that a woman's birth month affects reproduction later in life. Dr. Huber believes that it comes down to what women experience in their early years, which is dependant on the weather.
