Clomid has been known to stimulate ovulation in up to 80 percent of the women who take it, and more than half of those women will end up pregnant as a result of the drug. When it comes to fertility medications, Clomid is top dog, and where you find Clomid, you will most definitely hear about Clomid twins. So what’s the real deal? What is your likelihood of having twins when you take Clomid?

Why Does Clomid Cause Twins?

First of all, it’s important to understand how a drug like Clomid could help increase the chances of having twins in the first place. Clomid increases a woman’s chance of having twins because it helps the body produce extra hormones in order to grow and mature the follicles for ovulation.


This increases the estrogen levels in the body. Because of these things, a woman might have so much extra stimulation and nourishment for her reproductive system, that the body is “tricked” into producing more than one egg. When the body produces and releases more than one egg in a cycle, and that egg (or eggs!) are fertilized, the result is twins and/or multiples. It’s so interesting that just taking a medication like Clomid could actually produce twins, but really, how likely is it?

Chances of Twins On Clomid

If you are strictly going by what you hear and read online, it seems like everyone either has had twins while on Clomid or knows someone who has. However, the belief that Clomid causes a woman to have twins is highly overrated.

In actuality, taking Clomid doesn’t really increase a woman’s chances of having twins all that much. You see, a woman has a 1-3% chance of having twins naturally. When taking Clomid, that chance of having twins jumps to around 8 percent.

As you can see, the chance of having twins when taking Clomid does increase, but it’s really not all that much. If you were going according to internet rumors and mommy play groups, we wold have to say that just about 99% of women who take Clomid wind up having twins!

It’s also important to remember that the twins conceived as a result of Clomid are fraternal twins and not identical twins, since they come from two separate eggs instead of one egg. These are just a few things to consider when you are constantly hearing about “Clomid twins” and how common they actually are.
