Ovary Transplants Rejuvenate Old Mice
Another reason for guys to become a transvestite?
Rome, Italy: Scientists have discovered that when they transplant ovaries from young mice into aging female mice, not only does the procedure make the mice fertile again, but also it rejuvenates their behaviour and increases their lifespan. The question now is: could ovarian transplants in women have the same effect?
Dr Noriko Kagawa will tell the 26th annual meeting of the European Society of Human Reproduction and Embryology in Rome today (Tuesday) that successful ovarian transplants increased the lifespan of the mice by more than 40%. "At present ovarian transplants are performed with the aim of preserving a woman's fertility after cancer treatment for instance, or of extending her reproductive lifespan. However, the completely unexpected extra benefit of fertility-preserving procedures in our mouse studies indicates that there is a possibility that carrying out similar procedures in women could lengthen their lifespans in general," she said.
Imagine transplanted ovaries that didn't pop out eggs but which did pump out hormones. A way to slow aging?
40% longer life thru ovary transplants.
Dr Kagawa said: "All the mice in both experiments that had received transplants resumed the normal reproductive behaviour of young mice. They showed interest in male mice, mated and some had pups. Normally, old mice stay in the corner of the cage and don't move much, but the activity of mice that had had ovarian transplants was transformed into that of younger mice and they resumed quick movements. Furthermore, the lifespan of the mice who received young ovaries was much longer than that of the control mice: the mice that had received two ovaries lived for an average of 915 days, and the mice that had received one ovary, for an average of 877 days. The newest of our data show the life span of mice that received transplants of young ovaries was increased by more than 40%.
With humans the ovary transplants might help. But resulting hormone surge might boost the risk of breast and cervical cancer. The net effect on human lifespans is hard to estimate at this point. Though the eventual development of cures for cancer would eliminate some of the downsides of ovary transplants and of other means to restore youthful hormone levels.
This is awesome. I wonder if it somehow relates to telomeres though.
There have already been human ovary transplants.
Maybe only young ovaries to old subjects will extend longevity. Likewise with immunological matching.
This also works in dogs.
"Rottweiler study links ovaries with exceptional longevity"
"Exploring mechanisms of sex differences in longevity: lifetime ovary exposure and exceptional longevity in dogs"
It might be worth reading the recent press release:
Eat fish twice a week to delay menopause
- lifelong sun exposure increased the risk of it starting early.
- history of heavy physical activity also doubled the risk, as did high blood pressure
Too bad so little of our national budget is spent on increasing human longevity.
Wow wow ...
With the technology of stem cells and cloning of organs, which begin to function reliably, women will have a great advantage over men for a long time ...
Of course, if it is able to produce cloned testicles, men also have promising rejuvenation.
Wow indeed. I wonder if the impact would still be felt by freezing sections of my ovaries now while I'm still young to implant later in my 40s.
After being in relationship with Wilson for seven years,he broke up with me, I did everything possible to bring him back but all was in vain, I wanted him back so much because of the love I have for him, I begged him with everything, I made promises but he refused. I explained my problem to someone online and she suggested that I should contact a spell caster that could help me cast a spell to bring him back but I am the type that don't believed in spell, I had no choice than to try it, I meant a spell caster called Dr AKHERE and I email him, and he told me there was no problem that everything will be okay before three days, that my ex will return to me before three days, he cast the spell and surprisingly in the second day, it was around 4pm. My ex called me, I was so surprised, I answered the call and all he said was that he was so sorry for everything that happened, that he wanted me to return to him, that he loves me so much. I was so happy and went to him, that was how we started living together happily again. Since then, I have made promise that anybody I know that have a relationship problem, I would be of help to such person by referring him or her to the only real and powerful spell caster who helped me with my own problem and who is different from all the fake ones out there. Anybody could need the help of the spell caster, his email: AKHERETEMPLE@gmail.com
