Can cough syrup boost fertility?

As bizarre as it may sound, one tip for boosting fertility keeps making its rounds: drink cough syrup.

 

The guaifenesine contained in cough syrup is said to have an effect on the cervical mucus and to dilute it, thus facilitating the passage of sperm into the uterus. However, this has not (yet) been scientifically confirmed and therefore it’s not a safe way to boost fertility. Cough syrup is a medication and like any other it can lead to side effects. Cough syrup also contains many other active ingredients that are less beneficial for pregnancy. At the time of ovulation, the cervical mucus naturally becomes thinner.

It is therefore advisable not to experiment with any medical preparations. In case of problems around the cervix, it is best to seek medical advice immediately.
