Pill Data

In a previous post, I mentioned that the pill can fail to prevent ovulation, and still prevent pregnancy by preventing implantation. This is effectively giving the new embryo a death sentence.

From Science Daily, a little data on how often this might happen:

"Of the 150 women who used the pill consistently, three of the 96 women with normal weight ovulated, as did one of the 54 women with obesity."

Not a huge sample, but 4 in 150 is almost 3%

That's fairly high. At once a month, that is one event every three years.
