From that link:The mechanism of Plan B has yet to be definitively determined:
Research also suggests that the progestin (levonorgestrel) in Plan B may help avoid pregnancy by altering the movement of sperm. Some studies report that this progestin can cause cervical mucus to thicken, making it harder for sperm to reach an egg. Additional data reports that the presence of this progestin can cause sperm to become hyperactive or confused, thereby affecting the direction in which they swim.
How Plan B Works
The labeling as an abortificient was an error, though some types of "birth control" pills DO prevent implantation.
The final way that the pill works to prevent pregnancy has to do with the uterine lining. Hormonal contraceptives may cause changes to the lining of the uterus. The hormones in these methods can thin out or prevent the growth of uterine tissue. This may reduce the likelihood of implantation.
"Data from recent studies continues to provide strong evidence that Plan B does not prevent implantation (this also seems to be true for Ella, another emergency contraceptive option). The majority of research claims that the primary way that Plan B works is by preventing or delaying ovulation--if Plan B is taken before ovulation occurs. By not allowing the egg to release, there is nothing available for sperm to fertilize, thus preventing a pregnancy from occurring."
QW you should pay attention to this, when a egg does not release that is preventing ovulation.
Damn, is that how it works?
Back to the fact that all the links you posted described the various ways that Plan B might prevent fertilization?
All I am saying here is that, despite your assertion that you know the answer, science doesn't agree. That, like it or not, makes your opinion unsupported by actual evidence. The studies do show that Plan B is more effective if taken before ovulation, but no study yet exist to who the actual mechanism of how it works. Everything is guess work, the truth is we don't know what happens, and claiming otherwise is silly.
The truth is, they do know what happens as I have linked many many times.
Do you understand how ovulation works and when it starts? Please explain to me what ovulation is.
I will give you a hint the process starts before the egg is released. You nothing about women's reproductive help. Which is the whole problem with the issue.
I don't care if they don't want to cover plan b, but morons who can't even understand basic reproduction in a female should not be trying to debate how Plan B works. You have no clue.
