That being said, every source provided within this debate appears to be in agreement that taken properly Plan B is 89% effective with Preven coming it at 75%. Even in the unlikely circumstance that a woman could afford to use only emergency contraception after every sexual encounter, and indeed would, Plan B and Preven come in with success rates of 81% and 62%, respectively.
You are not doing your statistics right. Let's start with Preven. Where does the 75% figure come from? If women have sex on "white bead" days, days when according to the rhythm method (a.k.a. Standard Days Method) they are likely to be fertile, then there will be 8 pregnancies per 100 women PER TIME using no method. This is how
Princeton University puts it: "On average, if 100 women have unprotected intercourse once during the second or third week of their cycle [i.e. on white bead days], 8 will become pregnant."
So this is our first statistic: Using no method, 8 out of 100 will become pregnant for having sex once (one time) during the "white bead" fertility hot spot period of a woman's cycle.
The next question is what happens to this statistic if women take Preven afterward? The answer is that 2 will remain pregnant past implantation. So where does the 75% figure come from? Since 2 remain pregnant using Preven and 8 would remain pregnant not using Preven, then 6 pregnancies were eliminated. Since 6 is 75% of 8, meaning 6/8=0.75, this is why Princeton says "following treatment with [Preven], 2 will become pregnant (a 75% reduction in the risk of pregnancy)..."
The problem you are not realizing is that a 75% reduction in the risk of pregnancy PER TIME is an extremely ineffective method of birth control because conventional methods have MUCH LOWER rates of pregnancy. This is why Princeton says, "ECPs [morning-after pills]when used perfectly are not as effective as other methods of ongoing contraception when used perfectly." Remember how people used to laugh about teaching kids the rhythm method because they said the rate was so ineffective? Well, Preven has a much lower rate than that.
So let's examine the YEARLY statistic. Remember, the 75% statistic is just per time, not per year.
The Alan Guttmacher Institute says using no method 85 women out of 100 will get pregnant in a year.
So this is our second statistic: Using no method, 85 out of 100 women will become pregnant for having sex for a whole year.
What happens to this statistic if women take Preven after sex?
Princeton University says 38 women out of 100 will get pregnant in the year if they rely on Preven. So, if 85 women will get pregnant using no method, but 38 will remain pregnant past implantation using Preven, then 85-38=47 pregnancies were eliminated. Since 47 is 55% of 85, meaning 47/85=0.55, this means Preven is only 55% effective in eliminating unwanted pregnancy; in other words, used alone, the annual effectiveness of Preven is only 55% in terms of its ability to eliminate unwanted pregnancy.
In comparison, the version of the rhythm method known as the Standard Days Method is 94% effective. Let's do the calculation.
The Alan Guttmacher Institute says the Standard Days Method will lead to less than 5 pregnancies per 100 women in a year. That means 80 of the 85 pregnancies expected from no method were prevented by using the Standard Days Method. Since 80 is 94% of 85, meaning 80/85=0.94, this means that the Standard Days Method reduces the risk of unwanted pregnancy by 94%.
Remember how people were laughing at the idea of teaching kids the rhythm method because they said it is so ineffective that it will lead to
more abortions? Well, Preven is even more ineffective than the rhythm method. So why is the abortion industry saying it will prevent abortions?
Also note that Preven will abort a fertilized offspring between fertilization and implantation. So in addition to having more clinic abortions, and more RU-486 or Mifeprex abortions, you will also have abortions between fertilization and implantation using Preven. In contrast, the Standard Days Method prevents pregnancy under all definitions of pregnancy, not just the one proposed by abortion advocates to begin at implantation rather than fertilization.
Please admit that the fact that even you are not clear on the statistics shows how misinformed people are about morning-after pills. And because even people like you are misinformed, a culture of misinformation will lead young people to rely on the pills instead of other methods which are more effective.
Remember, since rates are based on proportion, even if couples do not always rely on the morning-after pill, nevertheless each time they do it contributes to the number of woman-years of reliance. And since the pills are less effective than other methods, it means more unwanted pregnancies will result than if couples had not been inclined to rely on the pills over conventional methods. The concept of woman-years is a statistical one. If a woman is exposed to a year’s worth of a given event, this is one woman-year of exposure. But if two women experience half a year’s worth of an event, this is still one woman-year of exposure. Thus, each time a couple relies on the morning-after pill over other methods, it will increase the number of woman-years of exposure to a method which happens to be far less effective than other methods. Statistically this will result in many more unwanted pregnancies and an increase in sales for the abortion industry.
(Note: It is a mistake to say that "Preven is 62% effective in eliminating pregnancy since 38 out of 100 will stay pregnant past implantation using Preven." The reason this is a mistake is because only 47 of the other 62 would have gotten pregnant. So if you are saying Preven is 62% effective you are making the mistake of counting the 15 that would not have gotten pregnant anyway. You would also be comparing apples and oranges with respect to the 75% per time figure, because this figure, like the 55% per year figure, is taken with respect to the number of pregnancies that would have remained otherwise.)

you have also provided no support for the claim that Planned Parenthood wishes to promote one emergency contraceptive over another.
I did but you probably missed it. Here is what the
abortion industry leader says about its involvement:
QUOTE
In November 1994, in an attempt to bring ECPs into the medical mainstream, the Center for Reproductive Law and Policy (CRLP) filed a citizen petition with the U.S. Food and Drug Administration (FDA), on behalf of a coalition of leading medical and public health groups, including Planned Parenthood of New York City.
...
In September 1998, the FDA approved the application of Gynétics, Inc. of Belle Mead, NJ, to market America’s first dedicated ECP product, the PREVEN Emergency Contraceptive Kit.
So, it is clear that Planned Parenthood was pushing Preven, which is by far the least effective of the two morning-after pill regimens.
Also, to take the mystery out of the morning-after pills, the morning-after pill is simply an added dose of the traditional birth control pill. There are two kinds of traditional birth control pills: the combination pill (estrogen plus progestin) and the progestin-only pill. Preven is an added dose of the combination type birth control pill, and Plan B is an added dose of the progestin-only birth control pill. The reason why the mystery exists is because some people do not want the public to know that the chemicals in the birth control pill have an antinidatory effect, just like the morning-after pill. An antinidatory effect means the chemicals can kill a baby between fertilization and implantation.
At any rate, it would be unreasonable to assume that Planned Parenthood did not know about the Plan B regimen, since the Plan B regimen simply means taking an added dose of progestin-only birth control pills. Thus, since they knew the Preven regimen simply meant taking an added dose of combination birth control pills, they would have known for a long time from experimentation about the effect of taking the progestin-only regimen found in Plan B. It is not like you need a chemistry lab to take an added dose of something already available. So, it is unreasonable to assume Planned Parenthood did not know about the both the comparative and overall ineffectiveness of the Preven regimen. Instead, the obvious likely motive is that the abortion industry wanted to increase sales.
Question of the Day: If that is not true, then why has the abortion industry, led by Planned Parenthood, not
withdrawn its support for Preven in view of Plan B?
Answer: Preven offers a higher profit margin for the abortion industry.
