Finally, I asked my sister for help, and she agreed to donate eggs.

"No one has had an egg donated specifically for research."

In between, she donated eggs to a couple who subsequently had a daughter.

Currently, the only way some of those women can become pregnant is to use an egg donated by another woman.

Now the one who has no eggs is six months pregnant with an egg donated by her friend.

You report that of the 23 donated eggs, only 11 developed into embryos.

Women who lack ovaries but want to become pregnant can do so with eggs donated by another woman, he said.

I've even asked her if she'd consider donating eggs, but she's done her research and doesn't like the look of the drugs involved.

After all, he said, older women can easily become pregnant if they use eggs donated by younger women.

He said he later discovered they had donated eggs under false names in 2003.
