And the battle is not over yet. – ‘The rate of infertility in humans, we should expect higher than it should be,’says Dr. ‘At least now, the evolution of our reproductive success rate have improved Something else is going on. ‘. Combining empirical evidence with a mathematical model in collaboration with Prof. Lewi Stone of the Department of Biomathematics unit develops, the researchers suggest that the bodies of men and women have become reproductive antagonists, not reproductive partners.
