Certain treatments in childhood have the effect of destroying people's ability to have genetically related children later on in life.Advances in fertility preservation are helping overcome this problem.
In a case reported recently, a woman -- age 24 -- gave birth to a child, relying on ovarian tissue taken from her when she was 9 years old, in other words before she had even reached puberty. The tissue was treated and frozen in a particular way, and then surgically reimplanted when she was interested in having a child. The tissue then produced ova capable of fertilization.
What's remarkable about this is that the tissue was taken at a time when the technique was not yet proved to be effective.
This technique had been successful with adult women, but this case offers proof-of-principle that the technique can work for prepubertal girls as well.
