Killer whales are just one of three species – we're one of the others - that continue to live long after they've stopped reproducing. But scientists still don't know why these three alone evolved this unusual menopausal ...
The hormonal mayhem, reduced fertility and hot flushes experienced by a woman in the run up to menopause may owe to warfare between her own genes, according to a team of scientists working in the United Kingdom and Japan.
After decades of laboring under other theories that never seemed to add up, a team led by biologist Rama Singh has concluded that what causes menopause in women is men.
If you are a male human, nothing puts a damper on romantic success like having your mother in tow. If you are a male northern muriqui monkey, however, mom's presence may be your best bet to find and successfully mate with ...

Women will soon be able to tell how many eggs they have in their ovaries in a simple hormone test that Australian researchers said Sunday could revolutionise family planning and fertility treatment.
