Beluga whales and narwhals go through menopause

Scientists have discovered that beluga whales and narwhals go through the menopause—taking the total number of species known to experience this to five.

Solving the evolutionary puzzle of menopause

Menopause in women and females from a few other "higher" species is probably a fluke of nature rather than evolution at work, according to a study published Wednesday.

Menopausal whales are influential and informative leaders

Menopause is a downright bizarre trait among animals. It's also rare. Outside of the human species, only the female members of two whale species outlive their reproductive lives in such a major way. Female killer whales typically ...

Turbulent nature of menopause triggered by gene battles

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.

Hot flashes? Thank evolution

A study of mortality and fertility patterns among seven species of wild apes and monkeys and their relatives, compared with similar data from hunter-gatherer humans, shows that menopause sets humans apart from other primates.

Menopause

Menopause is the permanent cessation of reproductive fertility some time before the end of the natural lifespan. The term was originally used to describe this reproductive change in human females, where the end of fertility was traditionally indicated by the permanent stopping of menstruation or "menses". The word "menopause" literally means the "end of monthly cycles" from the Greek words pausis (cessation) and the word root men (month).

The meaning of the word menopause has in more recent times been expanded to indicate the permanent discontinuation of female fertility in many other species, such as some matrilineal whales, despite the fact that such animals experience no menstrual cycles.
