Polycystic ovarian syndrome - also known as polycystic ovary syndrome or PCOS - is a condition that impacts women’s health and hormone levels, and in particular, their androgen levels.
But what exactly is PCOS, and what are the symptoms of PCOS? How common is this condition, and what complications can it cause for things like ovulation, childbearing, and other aspects of women’s health and pregnancy?
In this article, we’ve compiled everything you need to know about polycystic ovarian syndrome, including the risk factors to look out for, how to get a diagnosis, access to treatment, and how it might affect fertility and pregnancy.
What is Polycystic Ovarian Syndrome?
PCOS is a condition that impacts the ovaries and, subsequently, women’s overall health. Although many people tend to think of PCOS as a condition that only impacts women, it’s important to realize that PCOS can occur in anyone born with ovaries, including intersex people, transgender men, and those who identify as non-binary.
PCOS is a relatively common condition, with a prevalence rate of about 9% among women of reproductive age.
As the name would suggest, one of the main features of PCOS is the growth of cysts on the ovaries. These ovarian cysts are typically benign and result from underdeveloped ovarian follicles. These cysts and underdeveloped follicles can prevent ovulation from taking place.
Symptoms of PCOS
Because PCOS impacts hormone levels and can lead to excess androgen in the body, there are several symptoms of PCOS to note. For most people, these symptoms tend to appear in their late teens and early 20s.
PCOS symptoms include
- Irregular menstrual cycle, including irregular periods, heavy periods, or not having a period altogether
- Excessive hair growth - also known as hirsutism. This can include body hair or facial hair
- Infertility or difficulties conceiving
- Increased BMI due to weight gain or obesity
- Acne breakouts and oily skin
- Hair loss or thinning hair on the head
- Patches of darkened skin, especially on the neck, armpits, and groin
What Is the Cause of PCOS?
If you have PCOS, you might feel frustrated and overwhelmed regarding the myriad of symptoms. You might also be wondering what caused it.
Unfortunately, researchers and healthcare providers haven’t been able to pinpoint one clear cause of PCOS, but there are a few conditions that have been identified as possible risk factors for PCOS:
- Insulin resistance – Insulin plays a role in digestion and impacts how your body controls blood sugar levels. Insulin resistance is when your body’s glucose levels don’t respond to the insulin you produce, leading to higher blood sugar levels. Insulin resistance plays a role in PCOS because higher insulin levels lead the ovaries to produce more androgens, leading to a hormone imbalance. Insulin resistance can also lead to type 2 diabetes and other health problems.
- Androgen levels – High levels of androgens can suppress ovulation and worsen the symptoms of PCOS. While androgen is sometimes thought of as a ‘male hormone’, people of all genders produce androgens, albeit at different levels. If your body produces more androgens, this can contribute to PCOS.
- Inflammation – People with PCOS tend to have higher levels of inflammation in the body. This inflammation can increase androgen production by the ovaries, leading to an increased risk of high blood pressure and heart disease.
- Genetics – There is some evidence that genetics might influence PCOS. If other people in your family have PCOS, there is a greater chance that you will also have PCOS.
If you suspect you might have PCOS, the best thing to do is talk to your doctor or gynecologist. There isn’t one single blood test that can diagnose PCOS, rather, most doctors look for the presence of a few key factors. A blood test can check whether you have abnormally high androgen levels. A pelvic exam or ultrasound can look for the presence of cysts on the ovaries. Your doctor will also ask about your medical history, including any history of irregular menstrual periods.
A doctor might also test for other conditions related to PCOS, like cardiovascular disease, unusual cholesterol levels, high blood pressure, and insulin resistance.
Complications of PCOS
The overall general health of a woman is affected by PCOS, especially when she is in the reproductive age period. However, specific complications can be seen in various bodily systems and functions. These complications could be preconception, gestational or postnatal.
Effect on the Hormones
The hormones are maintained by the endocrine system, which is a very intricate and interdependent system. A disease in any of the endocrine glands will tamper with the delicate balance maintained in the body. Women with PCOS tend to have erratic mood swings, disrupted circadian rhythm, depression, and anxiety.
PCOS and Infertility
PCOS primarily causes anovulation, where the affected individual is unable to ovulate after an appropriate signal has induced the process. Failure to ovulate means fertilization cannot occur. Endometrial cancer is also a major cause of infertility in women living with PCOS. These women often need In Vitro Fertilization (IVF) to aid conception.
Pregnant women with PCOS are at a higher risk of miscarriage or preterm birth, gestational diabetes, and preeclampsia, and have a reduced chance of spontaneous vaginal delivery prompting the need for episiotomy or cesarean section. To Improve the pregnancy outcome, it is important to visit your obstetrician at determined intervals to discuss symptoms and expectations.
Effect on Metabolism
PCOS doesn’t only affect the reproductive health of women – it has a significant role to play in the metabolic processes of the body. One major complication of PCOS is a metabolic syndrome — this refers to a range of conditions including high blood pressure, high blood glucose levels, and unhealthy fat accumulation. These increases in the body mass index contribute to major cardiovascular diseases that may result from these syndromes.
As a result of this, pregnant women with PCOS have an even higher chance of pregnancy-induced hypertension and may go on to give birth to a baby with macrosomia. Babies born with macrosomia will often spend a long time in the intensive care unit, which may affect breastfeeding.
This is one of the extreme complications that could arise from PCOS. This cancer affects the uterine lining, which could compound the woman’s inability to conceive.
Treatment for PCOS
Treatment for PCOS typically includes medication and lifestyle changes. Medications can include things like birth control pills, as they can help control your menstrual cycle and lower androgen levels. Some women may also be offered diabetes medication to lower insulin resistance, such as metformin.
Lifestyle changes typically include activities that support weight loss, like exercise and eating a healthy diet. These lifestyle changes can also help lower blood sugar levels.
If you are trying to become pregnant, your doctor might refer you to a fertility specialist or prescribe medication that induces ovulation, like clomiphene or Clomid. These medications block estrogen receptors and trick the body into producing follicle-stimulating hormone, or FSH. However, these medications should be used with caution, as they can cause your body to release multiple eggs in one cycle and subsequently have a higher risk of resulting in twins or triplets.
In some rare cases, laparoscopic surgery can be used to treat PCOS. Laparoscopic surgery is a type of keyhole surgery – it allows the surgeon to make only small incisions rather than a large cut. A procedure called ovarian drilling which involves using a laser to puncture the ovary and induce normal ovulation may be carried out.
Getting Pregnancy with PCOS
For women in the gestational age, trying to conceive can be challenging. Because PCOS interferes with ovulation, getting pregnant can be more difficult. Studies estimate that as many as 80% of women with PCOS experience fertility issues. Far more research is needed in order to support women worldwide with this physically and emotionally draining illness.
Because PCOS can cause infertility, many women hoping to become mothers will wonder if they can get pregnant if they have PCOS. However, thanks to advances in reproductive medicine, most women with PCOS are able to get pregnant with some kind of medical intervention.
For some women, treatments that induce ovulation will be enough to help them conceive a child. For other women, artificial insemination procedures, such as IUI or IVF, will be necessary.
Although it may be hard and require special fertility treatment, it is possible for you to get pregnant if you have PCOS. Fertility treatment requires an equilibrium between contraception and induced ovulation.
Reaching a healthy weight and sugar levels during the prenatal years can also help reduce pregnancy complications.
Finding a PCOS Support Group
