If you’re a woman experiencing irregular periods, it’s likely been a part of your life for quite some time, well before you began your journey to parenthood. Now, as you try to conceive, these irregularities can transform from minor annoyances into sources of stress. “Many of my patients are puzzled about their menstrual cycles,” shares Dr. Emily Johnson, a specialist in reproductive health. “They come into my office worried that they won’t be able to conceive.”
The concern stems from the connection between menstruation and ovulation—the monthly release of a mature egg from the ovary, essential for conception. Without ovulation, there can be no pregnancy. However, Dr. Johnson reassures her patients that problems with ovulation are quite common and often treatable.
“I tell my patients that we can usually get to the bottom of it,” she explains. “There’s typically a reason behind irregular or absent ovulation. Once we identify that reason, we can often find a solution. If there are no other infertility issues like blocked fallopian tubes or poor semen analysis, most of these patients can successfully achieve pregnancy.”
In fact, women facing ovulatory disorders frequently have positive outcomes through straightforward treatments such as lifestyle adjustments and oral medications. Even those who require more advanced interventions, like IVF, often experience high success rates—around 55-60% for women under 37 when transferring a single, high-quality embryo.
What Happens During Ovulation?
To grasp the complexities of ovulatory disorders, it’s helpful to understand the normal ovulation cycle. Women are born with a limited number of eggs, each nestled in its own follicle within the ovaries. The pituitary gland controls these follicles through hormones like Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).
FSH prompts one follicle each month to start developing a mature egg. Once this follicle reaches about 2cm and produces a specific level of estrogen, the pituitary gland releases a surge of LH, triggering the release of the mature egg.
If ovulation isn’t happening consistently, it could indicate a communication breakdown between the ovaries and the pituitary gland.
Diagnosing the Issues
“We always keep an eye on thyroid function,” Dr. Johnson says, “as it collaborates closely with the pituitary gland in reproductive processes.” Hypothyroidism, where the thyroid doesn’t produce enough hormone, is a common thyroid issue found in women. Simple blood tests can effectively determine the cause of this miscommunication. All women undergoing infertility evaluation typically undergo similar tests that assess hormone levels critical to fertility, revealing common culprits behind ovulatory dysfunction.
“When the thyroid isn’t meeting the body’s metabolic demands,” Dr. Johnson notes, “patients often experience irregular cycles alongside symptoms like cold intolerance, weight gain, hair loss, and fatigue—this is easily managed with thyroid hormone replacement.” Prolactin levels are also checked, as high levels even in non-pregnant women can lead to cycle irregularities. An MRI of the pituitary gland may be necessary if elevated prolactin levels are detected, as some patients may have a benign adenoma causing these issues. Fortunately, this can also be treated with medication.
A thorough medical history is essential for a complete diagnosis. Dr. Johnson emphasizes that symptoms like acne, facial hair, and weight gain are particularly telling for diagnosing Polycystic Ovary Syndrome (PCOS), the most common ovulatory disorder. “Women often don’t connect these symptoms to their ovulation issues until I bring them up,” she adds.
The Bigger Picture of Fertility
Women with ovulatory disorders might think that’s the only reason for their infertility, but studies show many have additional underlying factors, including male infertility. “Before starting treatment, it’s crucial to conduct a comprehensive infertility evaluation, including testing the male partner,” Dr. Johnson advises. “If we manage to get you ovulating but discover issues like blocked tubes or low sperm count later on, ovulation alone won’t lead to success.”
This comprehensive evaluation includes a semen analysis for the male partner and an HSG test for the female partner to assess the health of the uterus and fallopian tubes. An ultrasound and hormone testing are standard procedures to evaluate egg and ovarian health. “We also recommend genetic testing,” Dr. Johnson adds.
Given the varying causes of ovulatory disorders, a one-size-fits-all treatment doesn’t exist. Below are some of the most common ovulatory disorders and their treatments.
Polycystic Ovary Syndrome (PCOS)
PCOS is the leading ovulatory disorder, affecting about 85% of women with ovulatory dysfunction. Women with PCOS experience an imbalance in FSH and LH hormones, often resulting in infrequent or absent periods. They may also deal with acne and excessive hair growth due to increased LH secretion throughout their cycle.
The lack of ovulation can lead to numerous small follicles forming on the ovaries, resembling pearls. Each of these follicles produces some estrogen, which can thicken the uterine lining, leading to irregular bleeding and potential anemia.
Another significant issue associated with PCOS is insulin resistance, which can contribute to weight gain and obesity. However, it’s essential to note that not all women with PCOS are overweight—about a third have a normal weight.
Treatment Options for PCOS
If there are no other infertility issues, women with PCOS typically start treatment with an oral medication and timed intercourse. Clomiphene, or Clomid, is often the first-line medication. It’s an antiestrogen that stimulates the pituitary gland to produce more FSH and LH, helping develop one or more egg follicles. While on Clomid, blood tests and ultrasounds are conducted to monitor follicle development. Once they reach the right size, an injection to trigger ovulation is given, and the couple is advised on optimal timing for intercourse.
If a few cycles of Clomid are unsuccessful, Dr. Johnson usually suggests adding injectable FSH to enhance the cycle’s effectiveness. Should timed intercourse not yield results, or if there are issues with semen analysis, Intrauterine Insemination (IUI) may be recommended.
In IUI, the sperm sample undergoes a ‘washing’ process to ensure only the healthiest sperm are placed in the uterus, timed just before ovulation. The success rates for ovulation induction with IUI are around 15% – 20% per cycle, with better odds for those under 35.
