Stem Cells That May Make Eggs Found In Women 142
sciencehabit writes "Men typically produce working sperm as long as they live, but most textbooks say female mammals are born with all the egg cells, or oocytes, they will ever have. Since 2004, however, reproductive biologist Jonathan Tilly of Massachusetts General Hospital in Boston has challenged that conventional wisdom, arguing that in mice—and perhaps also in humans—there must be an ongoing source of new eggs. Today, Tilly and his colleagues report isolating rare cells in ovarian tissue from adult women that can grow in lab dishes and form immature oocytes. The potential egg stem cells could help scientists devise new ways to help rescue the fertility of women who have to undergo cancer treatments or who suffer from premature menopause."

Most women lose their fertility for a reason. Whether it's menopause or cancer, getting pregnant is not a good idea in either case.

Trains and vehicles are unsafe. Humans do not move faster than they can run for a reason. How dare we either go against god or risk finding out why evolution made us this way!

Maybe you don't but this should freeze your balls:
Tilly holds a patent on the human egg stem cells
(and is starting a company to help alleviate human suffering and cash out on his find).
Hopefully, no public funds were used in this endeavor, otherwise I smell an ethical rat...

Unexplained infertility is a huge medical problem.
Is it?
It seems like an out of control population is a much, much larger problem.
