Juliet told Ben that the pregnancy problem was because of something that happens at conception. She asks Ben to let her take one of the women off the island and he tells her no.
Juliet tells Sun that men on the island have a higher sperm count, to explain why Jin who is supposed to be sterile, has now gotten Sun pregnant.
In Juliet's flashbacks we've seen that she used her own sister as a guinea pig and gotten her pregnant even though she had cancer.
It's my theory that Juliet was sterile before she came to the island. She became obsessed with pregnancy research because of this, and this is why she decided to work for Mittelos Bioscience.
Why she wants to get off the island so bad is because she wants to get pregnant and get off the island to have the baby.
It seems that the only women who can live through pregnancy are ones who got impregnated by someone who wasn't an Other.
Jin impregnated Sun. Thomas impregnated Claire (granted we don't really know who he was yet). And Jack impregnated Juliet. You know they did. She did it on purpose to test it out and see. She came to the island and was cured of her infertility, and sought out someone from the crash who she could have a kid with and then leave with him to start a family which is what she wanted all along.
