Are there chances of getting pregnant with twins on Clomid?

In the United States and Europe, Clomid (clomiphene citrate) is a commonly prescribed fertility drug. This medication helps to stimulate the ovaries to produce more hormones and egg follicles than usual. This allows more than one mature egg to develop. Since there are more developed eggs, the chance of getting pregnant with twins increases.

Clomid Success Rates

Clomiphene citrate has been used for fertility treatment for more than 50 years. The goal is to induce ovulation and normalize menstrual cycles. Of all women who are prescribed Clomid, 80% successfully ovulate, but only 50% of these women become pregnant.

Clomid’s success is limited by side effects, such as cervical mucus changes and endometrial effects. Secondary infertility factors also affect the drug’s success. In a recent study, it was found that 87% of women who ovulate on Clomid also have an additional cause of infertility, such as tubal disease, pelvic lesions, and endometriosis.

The Numbers

For women who conceive naturally, there is 2% chance of having twins. While taking Clomid may increase a woman’s chances of delivering twins, the numbers are not significant.

Clomid causes twin pregnancies about 10% of the time, and less than 1% of women taking Clomid have triplets or quadruplets. Of those women who have twin pregnancy on Clomid, only 1 of 5 twin pregnancies are identical twins. The rest result in fraternal twins.

How Clomid Works

Clomid or Clomiphene citrate works by blocking estrogen action in the body. This tricks your body to produce FSH (Follicle Stimulating Hormone) and LH (Luteinizing Hormone), which are necessary for ovulation. FSH helps the eggs to mature in the ovaries, and LH triggers the eggs release from the follicles.

You may be prescribed Clomid in pill form for 5 days of your menstrual cycle, and as long as 6 months. Most women are advised to start Clomid within 5 days of the period. Progesterone is also given to keep your reproductive cycle regular and to re-establish periods if you have irregular menses. Ovulation is expected between 5-9 days after you have taken the last Clomid pill. You may ovulate and conceive in the first month, or it may take several months before you ovulate regularly. Unfortunately, not all women respond to Clomid.

How Clomid increases twin pregnancies

Various factors increase the likelihood of a woman delivering twins while taking Clomid, such as –

  • Age – Women younger than 25 years of age are more likely to have twins while on Clomid.
  • Ovulation – Only women who have trouble ovulating should take Clomid. Anyone who ovulates regular, and takes this drug, has an increased chance of having twins.
  • Dose – Taking more than the recommended dose of Clomid increases chances of delivering twins.

Clomid Side Effects

Like all medications, Clomid has some side effects. These include:

  • Mood swings
  • Hot flashes
  • Blurred vision
  • Dizziness
  • Weight gain
  • Heavy periods
  • Breast tenderness
