Other treatments will become available sooner. OvaScience, a fertility company based inBoston which has exclusive rights to exploit Dr Tilly s research on mammalian ovarianstem cells, will begin offering a novel treatment in July. This uses a woman s own stem cellsto provide her eggs with extra energy by creating fresh mitochondria-sub-units that existwithin cells and supply them with energy. They too can become scarcer and less productivewith age. Previous studies have shown that boosting mitochondria can dramatically increasethe success rates of IVF. When it comes to reproduction, men will still have it easier forsome time. But women are catching up.
另一种疗法也将很快得到应用。波士顿的OvaScience公司独家开发Tilly博士的哺乳动物卵巢干细胞细胞研究。今年7月,该公司将开始提供一种全新的疗法:使用卵巢干细胞制造线粒体,给妇女的卵细胞增添活力。线粒体的数量和活力也会随着年龄增长而递减。此前的研究表明,增加线粒体数量能极大提高体外受精的成功率。谈起繁衍来,男人还能优哉游哉一阵子。不过,女人即将迎头赶上。
