If an evaluation shows you're not ovulating normally, your doctor may prescribe hormone medications. These can help stimulate egg development or trigger ovulation. They can also be used to adjust other hormone levels that affect fertility. In many cases, these medications are used for assisted reproduction treatments.
Stimulating Egg Development
Follicle stimulating hormone (FSH) medications stimulate the ovaries to produce more mature eggs each month. Be assured that this does not make a woman run out of eggs any faster. Instead, it simply means that more eggs (instead of just one) mature with each cycle.
Triggering Ovulation
Medication called human chorionic gonadotropin (hCG) is used to stimulate ovulation. This helps improve the timing for successful fertilization after sex. It may also be used during assisted reproduction treatments.
Adjusting Other Hormone Levels
To improve ovulation, medications may be prescribed to treat:
- Polycystic ovaries. An imbalance of insulin (a hormone that controls blood sugar levels) may cause immature eggs to form cysts on the ovaries. In turn, the cysts release male hormones that can prevent ovulation.
- Prolactin problems. An imbalance of the hormone prolactin can prevent normal ovulation.
- Thyroid problems. An imbalance of thyroid hormone levels can cause fertility problems or miscarriage.
Types of Medication
The chart below lists common medications prescribed for fertility treatments. Talk with your doctor about how these medications work. Be sure you understand how and when to use them. You should also be aware of the possible side effects. In particular, some medications carry a small but serious risk of enlarged ovaries (ovarian hyperstimulation syndrome). This requires prompt treatment.
Medication | How It Works | How It's Taken | Possible Side Effects |
Clomiphene citrate (Clomid, Serophene) | Stimulates egg development | Pills | Hot flashes, blurred vision, ovarian cysts, and increased chances of having twins |
Follicle stimulating hormone or FSH (Bravelle, Gonal-F, Follistim) | Stimulates the ovaries to produce more mature eggs | Injections | Increased chance of multiple births. Small but serious risk of enlarged ovaries |
Human menopausal gonadotropin or hMG (Repronex) | Stimulates egg development | Injections | Increased chance of multiple births. Small but serious risk of enlarged ovaries |
Human chorionic gonadotropin or hCG (Ovidrel, Pregnyl, Novarel ) | Triggers ovulation | Injections | May aggravate enlarged ovaries when combined with hMG or FSH medications |
Dopamine agonists (Parlodel, Dostinex) | Decreases prolactin, a hormone that can prevent ovulation | Pills | Nausea, nasal stuffiness, dizziness, and headache |
Levothyroxine (Synthroid, Levoxyl, Levothroid) | Restores thyroid hormones to a normal level | Pills | Nervousness, irritability, headache, insomnia, diarrhea, weight loss, and changes in menstruation |
