Q: Is Clomid the go-to medication for infertility?
A: Clomiphene citrate, commonly known as Clomid, falls under a category of drugs called anti-estrogens. It works by binding to estrogen receptors in the hypothalamus, tricking the brain into believing there’s a low level of estrogen in the bloodstream. As a result, the brain prompts the pituitary gland to release more follicle-stimulating hormone (FSH).
Why is Clomid So Popular?
Many women receive clomiphene prescriptions without a clear diagnosis, hoping it will boost fertility. Generally, this approach is safe and affordable. However, the drug’s effectiveness often hinges on its ability to stimulate the ovulation of multiple follicles (or eggs). Since it acts as an anti-estrogen, it can sometimes result in a thinner uterine lining, which may hinder pregnancy. To address this, we conduct at least one ultrasound during each treatment cycle to monitor endometrial thickness and the development of follicles. Patients are also encouraged to track their LH surge using an ovulation predictor kit. This allows us to plan intercourse or intrauterine insemination accordingly.
Who Are the Best Candidates for Clomid?
Clomid is particularly beneficial for women who don’t ovulate regularly, such as those with polycystic ovarian syndrome (PCOS). These women have functional ovaries but lack proper signaling from the brain to induce ovulation. A low dose of clomiphene can stimulate just enough FSH to help them ovulate a single egg. While most PCOS patients respond well to Clomid, some may need additional insulin-sensitizing medications for improved results. If a woman doesn’t respond to Clomid, it could indicate very low FSH and estrogen levels, known as hypothalamic anovulation, which typically requires injectable FSH for ovulation.
Normal Ovulators
Women who ovulate normally can still benefit from Clomid to enhance their hormonal response during ovulatory cycles. If they have low luteal phase progesterone levels, clomiphene can increase progesterone production, supporting embryo implantation. However, many women get diagnosed with low progesterone prematurely, often based on a “day 21” cycle check. A more accurate method involves using an ovulation predictor kit and testing progesterone levels seven days after the LH surge. If this level reaches 10 ng/ml or more, it indicates normal levels without a “luteal phase defect.”
Who Should Avoid Clomid?
In general, women aged 35 and older should consider skipping Clomid and opt for more aggressive treatments, like injectable FSH combined with intrauterine insemination or even in vitro fertilization. Additionally, women who experience a thinning of the uterine lining should not take clomiphene.
Potential Side Effects
While many women tolerate Clomid without issues, some may experience side effects akin to early menopause, such as hot flashes and mood swings. These side effects are rarely severe enough to halt treatment. However, if a patient experiences rare but significant visual disturbances, such as flashing lights, they should stop treatment immediately. The risk of multiple pregnancies with Clomid isn’t high; about a 5% chance of twins and 1% or less for triplets or more, depending on age.

In summary, Clomid is a widely used medication for stimulating ovulation, particularly for those with irregular ovulation or PCOS. While generally safe and effective, it’s crucial to monitor its effects and consider alternative treatments for certain individuals.
