Joaquin Llacer from Instituto Bernabeu (Alicante) offered one of the most brilliant\u00a0and awesome presentations at ESHRE Meeting held at Helsinki this month. It is\u00a0admitted that embryo aneuploidy frequency increases with women\u2019s age.\u00a0According to data from Instituto Bernabeu as much as 40,6% of analyzed embryos\u00a0showed some type of aneuploidy. Overall, this means that the fate of 4 out of 10\u00a0embryos will be either no implantation or a miscarriage. As expected, the\u00a0aneuploidy rate increased with age. The rate was higher than 80% among women\u00a0aged 42 and older. No news, here.<\/p>\n
But the relevance of Joaquin Llacer`s presentation was the high and in someway\u00a0surprising high rate of aneuploidies observed among women younger than 22.\u00a0More than 40% of embryos from women included in this young range were faulty\u00a0from a chromosomal point of view. This means that even in an egg donation\u00a0program it is worthwhile to analyze the embryos to be transferred.<\/p>\n
In summary, two lessons may be learned from this outstanding presentation. First,\u00a0the transfer of embryos without a chromosomal analysis (i.e. without performing a\u00a0genetic screening) will (should) be reduced in the future taking into account that\u00a0as much as 4 out of 10 embryos may be defective (so, 6 out of 10 useless embryo\u00a0transfers could be avoided). Second, and more surprisingly, even in the context of\u00a0an egg donation program genetic screening may be suitable. Anyway, if an egg\u00a0donation treatment is proposed, it is advisable to choose donors older than 21.<\/p>\n","protected":false},"excerpt":{"rendered":"
