Women in the 60s and 70s could theoretically have genetically related children one day. Groundbreaking techniques It converts DNA from skin cells into human eggs that can produce embryos.
Researchers at Oregon Health and Science University created early stage human embryos from DNA It was collected from skin cells and fertilized with sperm.
In its early stages, the experimental methods described in New researchwhich could open up the possibility of elderly women who have run out of eggs or same-sex couples who want a child genetically associated with both partners.
Some experts warn that the work is still in its early stages, but if successful, the technology will be ready for clinical use within 10-15 years.
Genetic variations in sperm donors associated with cancer in 10 pregnant children
Dr. Paul Amato, a Reproduction Endocrinologist and obstetrics and gynecology professor at Oregon Health and Science University in Portland told Fox News Digital to The Discovery and The The The study It was promising.
“It’s a very preliminary task at this stage, but if successful, it will provide hope for couples and those suffering from infertility, especially older women who have run out of eggs,” said Amato, who co-authored and co-examined recent research.
Amato, even if the method is working, Pregnancy at upper age poses a serious health risk.
“We still need to keep in mind that someone has to carry that pregnancy,” she said. “So, we’re not necessarily insisting that women in their 60s and 70s will have a pregnancy, but in theory, they can have genetically related children. We’ll predict this in at least 10 to 15 years.”
World Athletics introduces testing for gender eligibility requirements.
The experimental procedure begins with the nucleus of skin cells containing DNA.
Scientists remove the nucleus and insert it into the egg of a donor that has stripped its own nucleus.
Next, trigger the egg to discard half of the chromosome, reducing it from 46 to 23.
This is compatible with sperm fertilization and adds 23 other chromosomes.
If successful, the resulting embryo is Genetically normal It may be transferred to the uterus to begin pregnancy.

The technology can also help women who have previously received cancer therapy or who have transformed family planning for same-sex couples.
“It is possible that same-sex couples can have children genetically related to both partners,” Amato explained.
“Usually they need to use eggs from donors. Using this technique, you can create eggs using skin cells from one partner, fertilize them with sperm from the other partner, and produce babies that are genetically related to both.
“This is a preliminary task and there are a lot to understand before you’re ready,” Amato emphasized.
“Every embryo we create is actually genetically abnormal, with too many chromosomes or too many. We have a lot to do.”
