FOR MANY well-known reasons, women around the world are increasingly choosing to have babies in their mid-30s(35岁左右) and into their 40s. They face a considerable challenge: genetic errors in their eggs increase as they get older, leading to fewer pregnancies and more miscarriages.(她们面临一个相当大的挑战：随着年龄增长，卵子中的基因错误会增多，导致怀孕率下降、流产率上升。)
由于许多众所周知的原因，世界各地越来越多的女性选择在35岁左右到40多岁生育。她们面临一个相当大的挑战：随着年龄增长，卵子中的基因错误会增多，导致怀孕率下降、流产率上升。
In-vitro fertilisation(体外受精) (IVF) has long been the only solution offered to these women but, as it stands today(就目前而言), it is not fit-for-purpose(适用的) and can be an expensive and heartbreaking(令人心碎的) gamble(赌博；冒险). If they can tolerate the financial, physical and emotional burden, would-be mothers are advised to try the process as many times as they can bear.(如果她们能承受经济、身体和情感上的负担，准妈妈们被建议尽可能多地尝试这一过程。)
体外受精（IVF）长期以来是提供给这些女性的唯一解决方案，但就目前而言，它并不适用，而且可能是一场昂贵且令人心碎的赌博。如果她们能承受经济、身体和情感上的负担，准妈妈们被建议尽可能多地尝试这一过程。
Change may be on its way(即将到来). Two European startups want to increase women’s chances of having a baby with treatments to improve the viability(活力；生存能力) of human eggs. They are building on research that has peered deep inside the human egg to explain exactly why baby-making becomes so error-prone as women age.(他们基于深入研究人类卵子内部的研究，以准确解释为什么随着年龄增长，生育变得如此容易出错。) By identifying the molecules and processes responsible for faulty eggs, the companies hope to improve IVF outcomes for older women.
改变可能即将到来。两家欧洲初创公司希望通过改善人类卵子活力的疗法来提高女性生育的机会。他们基于深入研究人类卵子内部的研究，以准确解释为什么随着年龄增长，生育变得如此容易出错。通过识别导致卵子缺陷的分子和过程，这些公司希望改善高龄女性的试管婴儿结果。
