Oestrogen level and facial attractiveness of women

EN: This New Scientist article summarizes a publication [1] about the correlation of oestrogen level and facial attractiveness of women. The study claims that women are most attractive at the highest point of oestrogen concentration. This makes complete senses as at this time the ovulation takes places and mating should be done (at least in nature :)).
