Estimates are that from one out of 2,700 to one out of 900 artificially assisted pregnancies becomes heterotopic.
The location of the fertilized egg outside the uterus can vary, but it tends to end up in one of the fallopian tubes. This type of pregnancy occurs very rarely in natural conception, and tends to happen more in assisted fertilization.
Heterotopic pregnancy is also sometimes called multiple-sited pregnancy, combined ectopic pregnancy, or coincident pregnancy.

The patients argue they paid thousands of dollars for therapies that did not rid them of same-sex attractions, and that they then had to pay for mainstream therapy to repair the damage done by the conversion therapy.

However, the possibility remains that this apparently platonic coexistence is merely a façade, an elaborate dance covering up countless sexual impulses bubbling just beneath the surface.New research suggests that there may be some truth to this possibility—that we may think we’re capable of being “just friends” with members of the opposite sex, but the opportunity (or perceived opportunity) for “romance” is often lurking just around the corner, waiting to pounce at the most inopportune moment.The results suggest large gender differences in how men and women experience opposite-sex friendships.
