One fertility treatment company claims it can, by rejuvenating women's aging eggs. The company, called OvaScience, says its method aims to improve the health of an egg's mitochondria, which are the tiny powerhouses that give cells the energy to divide and grow.
But experts advise caution over those claims. Although some early evidence suggests aging mitochondria could reduce a woman's fertility, expert say, there are no studies that prove the new method will work. In addition, the company isn't forthcoming with details of its process.
