The Impact of PCOS On Fertility and Pregnancy
Polycystic ovary syndrome (PCOS) is a common hormonal and metabolic disorder that affects many women during their reproductive years. The condition is characterized by endocrine and metabolic abnormalities that can cause various symptoms, including skin problems such as;
- Acne and dark patches
- Irregular periods
- Weight gain
- Excessive hair growth or loss
- Fertility problems.
In this article, we will focus specifically on the impact of PCOS on fertility and pregnancy.
Regarding fertility, PCOS can have a significant impact; it is estimated that up to 70-80% of women with PCOS have difficulty achieving and maintaining pregnancy. Various factors can give rise to this, including irregular ovulation, abnormal hormone levels, and insulin resistance (1).
These issues can make it more difficult for a woman to conceive and carry a pregnancy to term. PCOS also increases the risk of miscarriage and complications during pregnancy, like gestational diabetes, a form of diabetes that occurs in some pregnant women who did not have diabetes before the pregnancy, and preterm labor.
How does PCOS Cause Infertility?
Irregular ovulation is among the primary causes of fertility problems in women with PCOS. Ovulation is when the female body releases an egg from the ovary almost every month during the reproductive years. Hormones regulate this process, and it occurs during the menstrual cycle.
In women with PCOS, the ovaries contain many small antral follicles that contain eggs, but they do not mature and ovulate as they should. Consequently, women with PCOS do not experience regular ovulation or periods. It can lead to difficulty becoming pregnant, as regular ovulation is necessary for pregnancy to happen (2).
In addition to irregular ovulation, women with PCOS may also have abnormal hormone levels and insulin resistance, which can further impact fertility. Insulin resistance occurs when the body's cells do not respond appropriately to insulin, a hormone produced by the pancreas that regulates blood sugar levels.
When the body resists insulin, it may produce more insulin to compensate. This can lead to an excess of androgens, or male hormones, in the body (3). Androgens can interfere with the normal functioning of the reproductive system, making it more difficult to conceive. Additionally, insulin resistance can increase the risk of miscarriage and complications during pregnancy, such as gestational diabetes and preterm labor.
Treatments Options to Improve Fertility Outcomes
Even though there is still no known cure for PCOS, various management techniques can help treat the condition and better menstrual regularity. Managing PCOS and its symptoms significantly increases the chances of having a successful pregnancy.
Work together with your healthcare provider
It is crucial that women with the condition work closely with their healthcare providers to develop a treatment plan tailored to their specific needs and goals.
Lifestyle changes
Lifestyle changes, such as maintaining a healthy diet and regular exercise, can help manage the symptoms and improve fertility.
Medications
Medications, like birth control pills or insulin-sensitizing drugs, can also be prescribed to help regulate menstrual cycles. Birth control pills also help reduce androgen levels, which can improve fertility. Insulin-sensitizing drugs like metformin help decrease insulin resistance and regulate menstrual cycles.
Medications that stimulate ovulation, such as clomiphene and letrozole, are also commonly used to treat and improve fertility in polycystic ovary syndrome (PCOS) and other conditions that cause irregular or absent ovulation.
Fertility treatments
Sometimes, fertility treatments, such as in vitro fertilization (IVF), may be necessary to achieve pregnancy in women with PCOS once other fertility treatments have been tried and unsuccessful.
IVF is a process in which eggs are removed from the ovaries and fertilized with sperm in a laboratory. The resulting embryo is then transferred back into the uterus. IVF can be an effective treatment for women who have not been able to become pregnant through other management options.
How to Overcome the Odds?
Treating PCOS can be challenging, and it is paramount for women with this condition to be proactive in seeking treatment and making the necessary lifestyle changes to improve their health.
This can involve changing dietary and exercise habits, taking medications as prescribed, and attending regular check-ups with a healthcare provider. Taking an active role in managing their condition can positively influence their chances of having a healthy pregnancy.
As mentioned above, PCOS is associated with an increased risk of insulin resistance which can lead to gestational diabetes. These can lead to complications such as preterm delivery, high blood pressure, and increased risk of cesarean delivery.
PCOS may also increase the risk of developing gestational hypertension and preeclampsia, characterized by high blood pressure and protein in the urine, and can lead to serious complications such as preterm delivery, placental abruption, and even death.
It is essential for women with PCOS to carefully manage their blood sugar levels during pregnancy in order to reduce the risk of complications. This may involve lifestyle changes such as following a healthy diet, exercising regularly, and taking medications to help improve insulin sensitivity.
In Conclusion
It is important to remember that though fertility problems are common in PCOS, they are often managed successfully. A holistic approach to treatment, which involves working with a team of healthcare professionals from different specialties, can be particularly effective for managing the various symptoms of PCOS.
Managing it may include fertility specialists and other healthcare professionals such as endocrinologists, primary care doctors, and mental health professionals. By addressing all aspects of the condition, it is possible to improve fertility outcomes and overall health in women with PCOS.
