If you have been struggling to become pregnant, you are probably ready to try just about anything so that you can conceive. This may include trying out a few old wives’ tales as well. One of the most popular things that women have said helped them to become pregnant is cough syrup. However, is there any truth behind the success of cough syrup and which kind works the best?

1. Cervical Mucus

The cough syrup that women often say helps with fertility is Robitussin. The reason that it may be effective is due to the main ingredient of the syrup, guaifenesin. It is believed that this key ingredient can improve your cervical mucus.

It is important to note that the presence of cervical mucus or the health of the mucus is required when you are trying to become pregnant. Many women have been able to conceive without it. However, cervical mucus does play an important role when it comes to conceiving.


Cervical mucus changes throughout the month. As a woman gets closer and closer to the time when she is fertile, her cervical mucus will become slippier and thin; similar to the yolk of an egg.

This type of mucus is the healthiest and promotes fertility by protecting sperm when it enters the body. It will then give sperm the tools that it needs to swim to the egg in an attempt to fertilize it. If cervical mucus is not healthy or is not present, the sperm may have a more difficult time reaching its mark.

2. Hostile Cervical Mucus

Another type of cervical mucus can actually hinder the sperm from getting to the egg at all. This cervical mucus is thick and makes it difficult for the sperm to swim. In the end it can create a barrier that prevents the sperm form travelling past your cervix.


It is best to have slippery cervical mucus, which is what you will find just before you ovulate. This is the best kind when you are trying to get pregnant. Many women have an abundant amount of healthy cervical mucus, but other women do not. If you do not notice the thin and stretch mucus that is typically present before ovulation, you may have hostile cervical mucus. Your doctor will be able to let you know for sure by performing a small test to check.

3. Cervical Mucus and Clomid

Some women have experienced hostile cervical mucus after they have been taking Clomid because it blocks the estrogen receptors in the body. These receptors are responsible for producing cervical mucus and if they are blocked healthy mucus will not be produced.


This may make Clomid ineffective for women who are trying to become pregnant, but some have found that taking Robitussin can help tremendously and solve the problem.

4. How does Robitussin improve cervical mucus?

Robitussin is designed to thin out the mucus in the lungs. By having thin mucus, you are able to cough up more of the mucus in order to clear it out of your system. This is fantastic because it also thins out your cervical mucus as well. Since this improves your chances of becoming pregnant, many women take Robitussin while they are trying to conceive for this reason.

5. When should you take Robitussin?

You should take Robitussin five days before you are scheduled to ovulate and on the day of ovulation. In order to determine the exact date it is important to monitor your ovulation cycle carefully.


You can do this by using a basal thermometer, but in this situation and ovulation prediction kit probably works the best. You should continue taking Robitussin for about two or three days following your positive reading. The dosage amount is two teaspoons three times daily.

6. Conclusion

You should talk to your doctor before taking any medication to improve your cervical mucus. It is a good idea that your doctor is aware of the things that you are putting in your body so that he can assess your health carefully.


Some medications may not interact well together and your doctor will be the best person to make this determination. While cough medicine wont’ necessarily increase your chances of becoming pregnant, it can definitely create an environment in which sperm can thrive and have a good chance of reaching the egg and fertilizing it.
