Pregnancy – Better For Women Than Thought?

The researchers at the National Institute of Mental Health in Maryland scanned the brains of 19 women who gave birth to 10 to boys and nine to girls. A comparison of images taken two to four weeks and three to four months after the women gave birth showed that grey matter volume increased by a small but significant amount in various parts of the brain. In adults, grey matter does not ordinarily change over a few months without significant learning, brain injury or illness, or major environmental change. The authors speculated that hormone levels and the need to cope with the challenges of a baby led to the increase in brain cells.

For the first time in the world, Jerusalem researchers have discovered that pregnancy has the remarkable ability to promote the regeneration in elderly mice of damaged livers and muscles. They have also managed to mimic the state of pregnancy using specific molecules that trigger the regeneration and growth of livers in older rodents.

This basic new concept from Hadassah University Medical Center and the Hebrew University-Hadassah Medical School could eventually be relevant to other tissues and organs and lead to the ability to stimulate their regeneration in elderly, sick patients.  Link

    Doesn’t having lactated before drastically reduce the chances of getting breast cancer?

    Yes, pregnancy decreases the risks of breast cancer, some studies skew towards teen pregnancy actually. That’s something the American Cancer Society won’t be advocating anytime soon 😛
