Ovulation Disorders (Anovulation): Causes, Symptoms & Treatment

Do you often miss periods without any clear reason? Does your menstrual cycle seem off? Or, have you been trying to conceive for a while without success? Ovulation disorders can be the culprit. A crucial part of your menstrual cycle—ovulation—plays a key role in fertility. 

Any irregularities in ovulation can affect your ability to get pregnant. One such ovulation disorder is anovulation. In this post, we will take a closer look at anovulation—common causes, how it affects fertility, and the best treatment options. Let’s get started.

What is Anovulation?

Anovulation is an ovulation disorder in which your ovaries do not release an egg. In a normal menstrual cycle, follicles containing eggs mature in your ovaries. Once the eggs are mature, they are released from the ovaries to the fallopian tubes, creating a possibility of fertilization and pregnancy. Anovulation means that the egg never gets released. To understand anovulation, we need to know how ovulation works.

How Ovulation Works

Ovulation may seem a complex process, but it’s just a timed coordination between your brain and the ovaries. It’s a hormone-controlled process. Your brain sends your body the signal to release hormones, including Follicle-stimulating hormone, which plays a key role in maturing an egg. 

With your egg reaching maturation, another major reproductive hormone, estrogen, also starts to rise. Estrogen is mainly responsible for preparing your uterus for a possible pregnancy. 

During this period, Luteinizing Hormone (LH) also surges. It triggers the egg release. That’s how ovulation works. Ovulation is a woman’s fertile window. The eggs are released into the fallopian tubes, where they stay for around a day. 

If intercourse happens during this period, there’s a higher chance the sperm will fertilize an egg and result in a healthy pregnancy, given that your overall reproductive health is normal. If the egg doesn’t get fertilized, the thickened uterine lining will shed and the new cycle begins.

For this pattern to occur normally every month, your brain signals and ovarian function must work together in perfect coordination. Disruption in any step of this process, whether it’s brain signals, imbalanced hormones, or a poor ovarian response, can increase the risk of ovarian disorders, including anovulation. 

Common Causes of Ovulation Disorders

There’s almost always an underlying cause of anovulation. Here’s a look at some common causes, most of which are treatable.

Hormonal Imbalances

Hormonal balance is the most crucial factor in a predictable ovulatory pattern. If hormones are out of balance, especially if you have high androgen levels, the risk of polycystic ovarian syndrome increases. This is one of the leading causes of anovulation. It may disrupt ovulation, preventing an egg from maturing and being released every month. 

Besides, thyroid disorders (both hypothyroidism and hyperthyroidism) are linked to disrupted hormonal signals needed for triggering ovulation. Even a slight disruption in thyroid function can affect your ovulation cycle.

Lifestyle Factors

Your lifestyle can also affect ovulation. Chronic stress, for example, can contribute to anovulation. When you are stressed, your body starts prioritizing functions that are vital for your survival, delaying reproduction. Chronic stress produces excessive cortisol, which prevents your brain from sending the right signal to your ovaries. 

Your weight also plays a significant role in regulating ovulation. Excessive weight can cause insulin resistance, which interferes with the hormones involved in ovulation, while being underweight signals your body to pause or stop ovulation, as your body may not be in a state to support pregnancy. 

Premature Ovarian Insufficiency

If your period has stopped or has become less frequent than normal, it’s important to rule out Premature Ovarian Insufficiency. It’s when your ovaries stop producing estrogen or releasing eggs into the fallopian tubes before the age of 40. 

Symptoms of Anovulation

Many women aren’t even aware of anovulation. They believe missing periods, having periods occasionally during the reproductive age, or changes in the bleeding pattern are all normal. 

While they may not always indicate a serious medical issue, it’s always worth seeing a gynecologist if anything about your menstrual cycle seems off. Here are the signs that may indicate anovulation:

• Irregular menstrual cycles, with periods being too short, too long, or unpredictable most of the time 
• Not getting period for months (without pregnancy or known medical reason)
• Not noticing any ovulation-related changes, such as changes in cervical mucus
• Trying to conceive without success

Remember, changes in the menstrual cycle aren’t always reliable for diagnosing anovulation. Many women have periods regularly, but do not ovulate. 

How Anovulation Affects Fertility

Every month, your ovaries release an egg, which waits for fertilization. When sperm penetrates and fertilizes the egg, it turns into a single-celled zygote. The cell division occurs rapidly, while your uterus prepares for an implantation. 

The zygote attaches itself to your uterine lining. After a successful implantation, your body starts producing the pregnancy hormone Human Chorionic Gonadotropin (HCG), which can be detected in a blood test. 

Anovulation is when no egg is released into the fallopian tubes for fertilization. Women with occasional anovulation may still have few opportunities to get pregnant, as the ovaries may occasionally release an egg. 

However, given the unpredictable pattern, it’s hard to predict ovulation and time your sexual intercourse accordingly to boost your chances of conception. For those who don’t ovulate for months or have stopped ovulating altogether, pregnancy is unlikely. 

While natural conception may not be possible, pregnancy can still take place through modern reproductive technology, such as in vitro fertilization. It bypasses natural ovulation and fertilizes an egg outside your womb after ovarian stimulation to give you the best chance to conceive. It may be the best choice of treatment for women who do not respond to ovulation-regulation medication, have blocked fallopian tubes, or have other ovulation disorders.

How is Anovulation Diagnosed?

Usually, a combination of tests is needed to detect anovulation. Here’s what’s used:

Hormone Tests: Since ovulation is a hormone-driven process, your fertility specialist will want to look at the levels of thyroid hormones, estrogen, FSH, and LH at different periods in your cycle to rule out hormonal imbalance. The test reveals if disrupted hormone levels are the reason your brain signals aren’t communicating with the ovaries efficiently.

Ultrasound Scan: Another painless and safe test to detect anovulation is an ultrasound. It checks the follicle growth and whether the egg is released from the ovaries. It can also detect fluid-filled sacs on the ovaries, suggesting PCOD or anovulation.

Ovulation Tracking: Sometimes, ovulation tracking kits can give signs of whether ovulation has occurred. Changes in the basal body temperature or a surge in LH just before the egg is released are some indicators of ovulation. However, these home tests aren’t always reliable. They are usually combined with medical tests for an accurate diagnosis.

Treatment Options for Ovulation Disorders

No need to panic if anovulation is the cause of your infertility. It’s often treatable. In fact, sometimes, lifestyle changes are enough to treat anovulation. Let’s explore common treatment options.

Lifestyle Changes

Lifestyle changes might seem insignificant for restoring ovulation. But you will be surprised to know that many women are able to regulate ovulatory cycles by correcting lifestyle factors. Let’s say you are overweight. Just losing a small percentage of the weight can help balance your hormones responsible for ovulation, thus restoring your ovulatory cycle. 

Likewise, if you are underweight, your body might send signals that it’s unsafe for pregnancy, thus pausing ovulation. Gaining a healthy amount of weight can help your body feel prepared for pregnancy.

Stress management techniques, such as meditation, journaling, or counseling, can also help regulate your hormones, restoring ovulation.

Medications

If lifestyle changes aren’t enough, the doctor may consider starting medication to regulate your ovulatory cycle. Medication can trigger your ovaries to mature an egg, release it, or create an ideal environment for ovulation. 

Women diagnosed with ovulation disorders, such as Polycystic Ovarian Syndrome, may respond well to medication. Once ovulation is restored, they can become pregnant. Letrozole and Clomid are commonly used for regulating ovulation.

Advanced Treatments

If medication also doesn’t help restore ovulation or you have additional fertility issues that medication or lifestyle changes cannot fix, more advanced treatment approaches may be needed. Here’s what your doctor may consider:

• Intrauterine Insemination: IUI is an assisted reproductive procedure in which healthy sperm cells are directly placed in your uterus through a small procedure. It’s advised for women with unpredictable ovulation cycles or mild to moderate fertility issues. 
• In Vitro Fertilization: For more complex cases, IVF may be recommended. It’s a multi-step procedure, where the ovaries are stimulated to produce multiple eggs at once, which are then retrieved after they have reached maturity. The eggs are sperm are placed together overnight for fertilization. The fertilized egg is then monitored in a controlled environment where they grow until they are ready for implantation. The fertilized egg/s are transferred into your uterus. 

Can You Get Pregnant with Anovulation?

Yes, you can. Many women with anovulation conceive. Some naturally, others with assisted reproductive technology. The goal is to restore ovulation so that the egg is released and available for fertilization. The success rates may, however, vary for women, depending on the cause of anovulation. 

For example, hormonal disorders can often be treated with medication, and lifestyle factors, such as weight issues or stress, can also be reversed. Once the underlying cause is identified and treated, ovulation will most likely return. That said, sometimes, infertility isn’t just linked to unpredictable ovulation cycles. Age-related decline in the egg reserve or quality can also affect your fertility. 

A fertility specialist will run all necessary tests to get a clear look at your overall reproductive and hormonal health and recommend treatment that works best for your case.

When Should You See a Fertility Specialist?

Here’s when you should book an appointment with your fertility specialist:

• Trying to get pregnant for more than a year (or 6 months if you are above 35) without results
• You have irregular periods 
• You have PCOS or thyroid disorders
