The hormonal ones start showing their effects according to the time of their insertion. If they are inserted within 7 days of onset of periods, then one can be carefree to rely on it completely. While, if it is inserted in any day of the month later, then one has to use some other birth control measure after 7 days of onset of periods till the 14th day.

The effectiveness of other barrier methods like diaphragms, sponges including cervical caps is also the same. One needs to go to the doctor for the correct insertion of these barriers. These need to be refitted with time.

There are even some sterilization processes for birth control. The process of tubal ligation creates an obstacle in the fallopian tube and prevents the egg from reaching its destination, the uterus. But it starts showing its effectiveness after 15-20 days of the process being carried out by surgery.

There is even another process called tubal occlusion in which the fallopian tubes are shut down prohibiting the entry of sperms and exit of ova thereby preventing their fusion to result in pregnancy. This is a medical process and hence should be carried out by a professional doctor only. But, it starts showing its effectiveness after a minimum of 3 months during which one needs to use some other birth control measures.

The natural way of preventing pregnancy is not as effective as the mechanical ones. In the case of man-made ones, barrier methods like the usage of pills and condoms, method is effective from the very time of their application. It gets activated to show its effects within few hours to few days.

The progesterone and combination pills take about 2-3 days to show their effects. With correct usage ensuring all precautions to be taken, it is effective in almost all cases. The IUD method is effective for a period of 6-10 years depending on the type and brand of IUD used. They start showing their effects after 7-10 days of being administered by the doctor.

The condoms are effective right at the moment of their application. While diaphragms are proven effective in 88% of the cases, female condoms are proven effective in about 79% of the cases.

On the other hand, male condoms are effective in about 82% of the cases. The combined use of these barriers is known to increase the effectiveness significantly. The usage of the vaginal ring has been proven effective in 90% of the cases and has taken about 7 days to be effective. There are even birth control injections that are effective within 7 days of their usage.

Surgical methods like vasectomy and others are proven effective in about 100% of the cases and are effective after healing the wounds. While there are various birth control methods, all of them except the surgical ones are not fully effective. They take time to show their effects. Even after perfect usage, sometimes they fail to stop pregnancy leading to unwanted pregnancies.
