How to Know your contraceptive options

Not everyone has access to sex education or have parents that guide them through the workings of sex, not to mention the shame associated with asking questions about it.

However, anyone partaking in the activity should know of the possible consequences of sex as well.

Unwanted pregnancies may be a welcome surprise sometimes, but it’s not always the case. Therefore, it is important for you to know your contraceptive options.

Hormonal Contraceptives

Hormonal contraceptives should always be taken at the discretion of the doctor. They are not suitable for everyone and thus can lead to complications. Moreover, it is important to fully understand the process as per the type of contraception you are option for. Hence, talk to the bestGynecologist in Karachi to find the best option available to you. Following are some options to choose from:

1 Birth control Pills

There are two types of birth control pills available. Combined oral contraceptive pill (COC) contains both estrogen and progesterone that prevent the release of the egg. Moreover, they also thicken the mucous around the cervix which helps to produce a physical barrier against sperm entry as well.

Another type is the Progesterone-only pill. While it allows for the process of ovulation to occur, it works by thickening the cervix mucus to prevent sperm from gaining entry into the uterus.

These pills are to be taken every day and has an effectiveness of about 91%.

2 Birth control patches

These patches work on the same principle as the COC. The benefit of the patch is that it has to be changed every week, unlike the pills that are to be taken daily.

3 Birth control Shots

Injections are also available that prevent ovulation and hence pregnancy. When used correctly, these injections are 99% effective. Depending on the type of injection chosen, one shot can last you anywhere from 8-13 weeks. Therefore, for women who are liable to forget to change the patch or take the pill, this is perfect.

4 Vaginal Ring

In this type of contraceptive, a soft ring in inserted inside of the vagina that releases progesterone and estrogen, and thus works similar to COC. The ring stays inside for 3 weeks and is removed for 1 week for women to have their periods.

5 Morning After Pill

This pill is mostly for damage control and is to be taken ideally within 24 hours of unprotected sex. It can work for up to 4-5 days, but with each passing day, its effectiveness decreases.

Morning after pill can lead to hormonal issues that can potentially last for months even, hence, it is recommended to be on guard with the contraceptives otherwise to avoid this unnecessary ordeal.

6 Birth control Implant

A tiny rod is ‘implanted’ into the female that releases the hormones to prevent pregnancy. It works like COC, except is much more convenient as one implant can last up to 5 years and can be removed whenever wanted.


Intrauterine Device is almost 99 % effective and can last for several years. Inserted inside of the uterus, this device works by either causing hormonal changes, like in COC, or by repelling the sperm from making it to the egg, as in the case of copper Paragard IUD.

Barrier Methods

Physical barriers are another form of contraceptives that are aimed at preventing the sperm from getting to the egg. Such methods are popular also as they do not cause any hormonal changes.

Contraception is a method to prevent pregnancies by eventually preventing ovulation.
