Powdered eggs could be new IVF solution

Women who want to delay giving birth until later in life may soon be able to have their eggs dried into a powder that they can keep at home until needed.

Researchers have developed a way of freeze–drying eggs so that they can be kept at room temperature almost indefinitely in sealed sachets. To revitalise the eggs for use in fertility treatment, they then just add water.The technique should make it easier and cheaper for women who want to store their eggs so they can undergo IVF treatment later in life or for women undergoing cancer treatment, which can leave them infertile.
