Graphing "failure rate" by birth control method such as pill · condom · ejaculation ejaculation

ByHey Paul Studios

Children are said to be gifts, but "pregnancy" to prevent unexpected pregnancy due to planned life design is important. From a well-known contraceptive tool such as a condom or a pill to a female condom, a hormone injection, etc., a method of contraception which is not familiar, it is like this when graphing "failure rate" of each contraceptive method.

This is a graph showing contraceptive "failure rate" of condom which is one of the most common contraceptive devices. The graph above shows the failure rate for "ordinary usage" by an ordinary person without special knowledge, and the graph below shows the failure rate in the original "proper usage" of the contraceptive device. The "failure rate" is the probability that unexpected pregnancy will occur if you continue to adopt contraceptive methods during that period.


In the graph, the horizontal axis is the period and the vertical axis is the failure rate. For example, if you hover over the year in the graph above, the mouse cursor is 18%. Changing the mouse cursor on the graph will change the probability. This indicates that 18 out of 100 women will have unexpected pregnancy when continuing sexual intercourse with condoms in normal usage for one year.


On the other hand, if you move the mouse cursor over 10 years, 86%. Under general usage, you can see that the probability of failure to use contraception in 10 years is quite high.


In addition, 18% in 10 years if it is correct usage. Whether it feels more or less is likely to be up to that person, but you can also see that there are considerable discrepancies in the results of "general usage" and "proper usage".


Therefore, the failure rate when using a typical contraceptive device is like this.

·Spermicide


The two horizontal lines of the graph show the line with the hazard ratio of 50% and the line of 25% in order from the top. In the case of spermicide, you can see that it is over 50% in the fourth year even in the correct usage.

· Avoidance of "dangerous day"


It seems like this is a contraceptive law by women's "self-assessment". Was the failure due to misunderstanding or just as you intended?

·Contraceptive sponge


Contraception sponge is not like "correct usage" etc.

· Extravaginal ejaculation


Male-led contraception law. As it should be, the failure rate should be known.

·Women's condom


Compared to female condom for males, failure rate by correct usage is higher.

·Diaphragm


It may be difficult to use correctly as women's condom.

·Pills (oral contraceptives)


If you prescribe correctly, the contraceptive effect of the pill is outstanding.

·Depot Provera


Depot Provera is a method of contraception that injects female hormones.

· Others
A list of contraceptive methods that can no longer be assumed as "how to use ordinary" is like this. From the left,IUD, Female sterilization surgery,Levonorgestrel, Male sterilization surgery, hormonal implant.
