Scientists have taken the first steps towards the development of artificial ovaries, which can lead to the development of fertility treatments, and help women at risk of infertility, such as those who receive bad cancer treatments. chemotherapy.
Experts say the study is "exciting", but further tests are needed.
Cancer treatments, such as chemotherapy and radiation therapy, often damage the ovaries and cause infertility in women. 19659002] There is a way to preserve the chances of these women during pregnancy, Is a culture of ovarian tissue, where all or part of the ovary is cut and frozen before it can be damaged, and can be used later.
This is the only fertility treatment available for girls who have not started producing Eggs.
But there is little risk of danger for people with cancer, a possibility that ovarian ovarian tissue contains cancer cells, increasing the chances of recurrence once the culture is produced
. "Very limited", but this may result in the unavailability of the culture process for women of some cancer species, such as leukemia or uterine cancers.
To eliminate this potential risk, scientists at the Copenhagen, Denmark hospital have removed ovarian follicles and ovarian tissue from patients undergoing treatment for cancer. They then removed the cancer cells from the ovarian tissue, leaving a "scaffold" of protein and collagen.
Scientists then implanted ovarian follicles on these artificial scaffolds of ovarian tissue.
This artificial ovary was cultured in mice, to support the survival and growth of ovarian cells.
Experts say that these are The technique "must" be tested in humans, which should occur in three or four years.
However, experts say that the technique may have advantages over other fertility treatments.
