Scientists Find Women Can Produce New Eggs After All

Health class taught you that women were born with all the eggs they’d ever have throughout their lives, but science has cast doubt on that supposition. New research finds that women can make new eggs throughout their reproductive years, thanks to stem cells in ovaries.
National Geographic reports scientists identified the stem cells in mice ovaries in a study published in 2004, but researchers in Boston’s Vincent Center for Reproductive Biology at Massachusetts General Hospital have finally identified the stem cells in humans. The researchers used donated ovary tissue from Japanese women who had gotten sex changes.

The findings could pay dividends in future fertility treatments, potentially opening up new avenues for doctors to help women develop more eggs.

    7 billion people on planet, are we really sure advances like this are good idea?

      The people who need to seek fertility treatments are probably not the same people who are overpopulating the earth.

    • Verdant Pine Trees says:

      It’s disappointing that the incorrect assumptions of Paul Erlich are still accepted as gospel on many college campuses, when the situation has many more shades of gray. There’s a correlation between education of women and birth rate. This is why we have a negative or near negative birth rate in Western countries, leavened only with immigrants from other countries.

      The best thing to do with concerns about overpopulation, is to push for more education and improved conditions for women in countries like China, and India, especially in rural areas. The more educated a woman is, the better her life, the longer before she gets married, the longer before her first child, and the better off, educationally and health wise, she can make her child. She has more resources. Slowly, this is starting to happen in China and India’s urban centers. Mexico, too, has had a huge drop in its birth rate due to the greater education of women, and the growth in the middle class. That means better quality of life.

      The issue with overpopulation is unwanted or unplanned children in developing countries. For both women, men, and their children, it’s better if they can hold off on marriage till they are 20 or older, versus the 14 and even 12 year old mothers you see in impoverished areas. Many of the children born will have poor health and some will never make it to adulthood.

      But most people who will use this are infertile people in the Western world. For every quiverful family with many children, you have Western families in which there is just one, or two children. It used to be routine for families to have three, four, five or more children. Now, people often want to provide better resources for fewer children.

      Children conceived and adopted by infertile or subfertile people, are desperately wanted children. Infertile people don’t care whether the baby is a girl or a boy, they just want a healthy kid. Octomom is a big outlier – most of them, because of the cost of treatment or adoption, or because of the time and expense they want to focus on individual children, will aim for one to three children – like most families.

      Some people cannot understand the pain of infertility, and glibly tell people to adopt rather than to try for their own biological offspring – which is not the inexpensive, fast process it’s assumed to be. Meanwhile, in countries like India and China, girls are abandoned or sometimes killed at birth. People even try to have more children specifically so they can try for a boy, and sex-selective abortion is a very real issue that we’re starting to see among some immigrants in Canada and the US. In rural China, millions of men will never have the chance to have even one child, or to get married, due to the lost generation of girls that don’t exist.

      Again, infertile people in the West want healthy babies, and not Octomom numbers of children. Newer eggs are better eggs, with less chance of birth defects. As someone who’s infertile, I think the best thing we can do is to try and get the developing world up to speed on women’s rights and better conditions for everyone. Without this technology, with current trends of women in the West needing more education to get a job and compete with longer-lived people, you’ll see continued infertility, and more importing of adoptable but unwanted children from developing countries. I think it’s a better idea that all children be wanted.

      May you never learn first hand how cold and cruel your comment is.

    For a second I thought that sign in the picture said “Because we’re better than you” rather than, “Making shopping better for you.”

    Hi. I’m a consumer review site. Let me post this wonderful fertility article that has nothing to do with consumer issues.

  5. brandonsavage says:

    Are they advocating selling eggs as caviar or something? Otherwise I’m missing the consumer connection.

    • MrMagoo is usually sarcastic says:

      Eggs make babies, which turn into consumers.

      Or parasites.

    • elephant says:

      As a consumer I’m currently spending mega bucks on fertility treatments, so yes, this issue is pertinent… the science is too late for me, but good to know it’s down the road!

    • Jules Noctambule says:

      So fertility treatments don’t cost money? Interesting.

  6. StatusfriedCrustomer says:

    Can’t think of a NewEgg joke.

    • Cream Of Meat says:

      um… I get my new eggs at NewEgg dot com.

      (If I ordered from tiger direct, would a tiger pop out of my vagina?)

    I’m amazed at all of the things people believe, just because that is what they were told.

  9. Conformist138 says:

    Add this to the list of things humanity should be ashamed of having JUST figured out. Humans got to the moon and back and have technology to send just about any information to anywhere in the world nearly instantly… but we still don’t quite know the answer to “where do babies come from?”

  10. milty45654 says:

    How’s this a consumer issue?

    • elephant says:

      Fertility treatments are a big business – Little insurance coverage means most patients pay out of pocket. Lucky you that this isn’t a concern for you, but as a consumer this is very pertinent to me.

    • Happy Tinfoil Cat says:

      For many reasons, mostly for things like this:

      The religious implications will overflow into governmental regulations and into the textbooks of public schools. I’m just waiting for the first screw-up from helping a sterile woman generate an army of babies. And to tie in the link, she may need two just to handle the extra load.

    Time to rewrite science books..

    Women, they always find new ways to surprise you.

  13. smo0 says:

    I don’t want kids – where can I donate these stem cells for money… lots and lots of money.

  14. HogwartsProfessor says:

    Good. I’m old and want to have a baby. Not done yet; still buying “feminine” supplies. Come on, eggs!
