If you are struggling to get pregnant, the chances are great that you have heard of Clomid. It is often the initial drug that is prescribed to women who are having a difficult time becoming pregnant.

It also has a great success rate and many women have been able to become pregnant quickly after they take it. However, there are side effects involved with Clomid.

As with most fertility drugs there is a fear among some women that they will find themselves dealing with multiple births after taking a fertility drug. Clomid does, in fact, raise your chances of having twins, but it is still fairly unlikely.

1. What does Clomid Do?

Why does Clomid increase your chance of conceiving twins? Understanding the answer to this question requires a deeper knowledge as to the ways that Clomid works. When you take Clomid, the estrogen receptors in your brain are being blocked.


The ovulation process requires estrogen in order to work, so by blocking the receptors you are able to regulate it better. When you first enter your menstrual cycle, the levels of estrogen that are in your body are low.

During this time, your eggs will start to mature, which causes them to release estrogen. The more that your eggs mature the more estrogen that they will produce and once the level of estrogen reaches a certain height, your body will begin producing the hormone LH. Ovulation is triggered by LH.

2. How does Clomid Work?

The way Clomid works in the body is that it is very similar to estrogen. In fact, the receptors in your brain believe that Clomid really is estrogen and they allow the drug to attach to the receptor cell.

Once Clomid has been attached, your body’s natural estrogen will not be able to attach. Your body will then begin to believe that it is not producing enough estrogen.


If it decides that it is not making enough estrogen, your body will begin creating other hormones that nurture and help your follicles to mature as they are growing in your ovaries. The reason the body begins focusing on the follicles is because they are what produces estrogen that your body needs.

3. Why are you at a greater risk of having twins?

The increase in the chances of having twins is related to the function that Clomid has in the body. While it is increasing your body’s production of the hormones that encourage your follicles to grow and to mature, it is also increasing your estrogen levels. This leads to added stimulation, which will then cause a woman to produce more than one mature egg.


When there is more than one mature egg released during ovulation, there is a great chance that they will both be fertilized and. This could result in becoming pregnant with twins. Most often, these cases result in producing fraternal twins rather than identical twins because they were conceived from two separate eggs.

4. What are the chances?

In a normal pregnancy, you have about one to three percent chance of becoming pregnant with twins. However, if you are taking Clomid, that chance rises to around eight percent. While this is an increase, it is not that drastic of a difference to worry most couples.


Chances are, if you have been struggling to get pregnant, the thought of having twins may be welcome, especially for couples who are planning to have more than one child anyway. This possibility could save on the added costs of childbirth and future fertility treatments if you decide to begin the process of becoming pregnant again in the future.

5. Conclusion

Some couples avoid taking fertility drugs because of the risk of becoming pregnant with twins. However, it is important to note that the chances of having twins is still pretty slim and not much higher than what you would see during a normal pregnancy.


If you are considering taking fertility drugs, you should talk your concerns over with your doctor so that you know exactly what to expect and if you have any medical history that may make your chances of having twins more of a reality. Some couples, who have a history of having twins in the family, may see that their chances of having twins rises a bit more than others who do not.
