Medical News: Novel 'Morning-After' Pill Works for Five Days - in OB/Gyn, Pregnancy from MedPage Today
birth control is being marketed to women in Europe. This new morning after pill, Ella One, containing ulipristal 30mg, is said to be useful for up to 120 hours (5 days) AFTER intercourse.
The study (1241 women) mentioned in this article indicates that ulipristal reduces the pregnancy rate from the expected 5.5 percent down to 2.1 percent.
In this study, the women who used the pill later after intercourse had lower pregnancy rates than the earlier users, though the differences among the groups were not statistically significant. If a larger study were to replicate this trend within statistical significance it would add more evidence for the pill's post fertilization effects. Those who understand the reproductive processes find it intuitively obvious that pills reducing pregnancy rate AFTER intercourse work to a significant degree by killing the embryo shortly after it is formed.
That ethical problem aside, women should be aware that a pill reducing the pregnancy rate from 5.5 percent to 2.1 percent should not be considered reliable.
The data here indicates that it fails to stop nearly 40 percent of the pregnancies, under study conditions with more education and oversight than usual circumstances.
