A Journey Toward Parenthood: Understanding Female Infertility

The desire to start a family is one of the most intimate and heartfelt journeys a woman can embark upon. For many, it’s a dream nurtured for years, filled with hope and anticipation. Yet, when months stretch into years without the arrival of a positive pregnancy test, feelings of frustration, sadness, and anxiety often emerge, creating an emotional burden that can deeply affect a woman’s well-being. Female infertility is a reality that can take a toll not only on mental and physical health but also on relationships, adding layers of complexity to an already challenging experience.

Infertility is a common struggle, affecting countless women worldwide. According to the World Health Organization, around 17.5% of the global adult population—or roughly 1 in 6 individuals—experiences infertility at some point in their lives. While this statistic sheds light on how widespread the issue is, it’s crucial to remember that diagnosing infertility requires more than self-reflection or speculation. It demands a thorough medical evaluation by professionals who can provide the right guidance.

2 Types of Female Infertility

When it comes to female infertility, understanding its different forms can be the first step in finding the right approach to diagnosis and treatment. Infertility is not a one-size-fits-all issue, and for many women, knowing which type they are experiencing can offer a clearer path forward. Female infertility is generally classified into two main types:

1. Primary infertility: This is when a woman has never been able to conceive, despite having regular, unprotected intercourse for at least a year. For women facing primary infertility, the inability to experience pregnancy for the first time can be especially disheartening, as the anticipation of starting a family remains unmet. The causes of primary infertility can be varied and complex, ranging from ovulation disorders and structural issues in the reproductive organs to unexplained infertility, where no specific cause can be pinpointed even after thorough evaluation.

2. Secondary infertility: In contrast, secondary infertility occurs when a woman who has successfully conceived and carried a pregnancy to term in the past is now struggling to conceive again. For many women, the experience of secondary infertility can feel particularly confusing and isolating. Having once experienced pregnancy, it’s easy to assume future pregnancies will follow naturally, but for those grappling with secondary infertility, the unexpected difficulty can cause immense emotional strain. Much like primary infertility, the underlying causes may include factors such as an age-related decline in fertility, hormonal imbalances, or complications from a previous pregnancy or surgery.

5 Common Causes of Female Infertility

Infertility in women can stem from a variety of underlying causes, each with its unique impact on fertility. Gaining insight into these causes is essential, as it not only helps in identifying the right diagnosis but also informs the most effective treatment strategies. By understanding the factors that contribute to female infertility, women can better navigate their journey toward conception and increase their chances of achieving a successful pregnancy.

1. Ovulation disorders: One of the most common causes of infertility is a disruption in ovulation. Ovulation disorders can prevent the ovaries from releasing eggs regularly or at all. Conditions like polycystic ovary syndrome (PCOS) affect approximately 8-13% of women of reproductive age and can lead to irregular or absent periods with over 70% of affected women remaining undiagnosed.  Women with PCOS often have higher levels of androgens (male hormones), which can interfere with egg development. Similarly, thyroid imbalances, both hyperthyroidism (overactive thyroid) and hypothyroidism (underactive thyroid), can impact ovulation and fertility.  Additionally, conditions such as primary ovarian insufficiency can occur due to autoimmune responses or genetic factors, leading to the premature loss of eggs. Excessive prolactin production (hyperprolactinemia) can also disrupt hormonal balance and cause infertility.
2. Fallopian tube damage: The fallopian tubes play a crucial role in transporting the egg from the ovaries to the uterus. Damage or blockage in these tubes can prevent fertilisation. According to the American Society for Reproductive Medicine, about 25% of infertility cases in women are attributed to fallopian tube problems. Pelvic Inflammatory Disease or PID, is often caused by untreated sexually transmitted infections (STIs) and can lead to scarring or blockages in the fallopian tubes. This scarring can hinder the passage of the egg, making conception difficult. Endometriosis is another condition that occurs when tissue similar to the uterine lining grows outside the uterus creating adhesions that block the fallopian tube and the uterus lining further complicating the fertility journey.
3. Uterine abnormalities: A healthy uterus is vital for implantation and the growth of an embryo. Uterine abnormalities can significantly hinder this process. Conditions like fibroids, which are nothing but benign growths in the uterus, can affect approximately 20% to 80% of women and play a significant role in female infertility. These growths or fibroids can distort the shape of the uterus or interfere with implantation. Congenital anomalies of the uterus or cervical factors, such as cervical stenosis, can also contribute to infertility by blocking sperm passage.
4. Age-related factors: As women age, their fertility naturally declines, especially after their mid-30s. Women are born with a finite number of eggs, and as they age, both the quantity and quality of these eggs diminish. This decline in egg quality can lead to difficulties in conception and an increased risk of miscarriage. In fact, for women in their early to mid-20s, the likelihood of conceiving each month is approximately 25-30%. However, fertility begins to gradually decline once a woman reaches her early 30s. This decline becomes more pronounced after the age of 35 and by the age of 40, the chances of becoming pregnant in any given month drop to roughly 5%.
5. Other Contributing Factors: In addition to the primary causes of female infertility, several other factors can play a significant role:
   • Autoimmune Diseases: Conditions such as lupus and rheumatoid arthritis can impact fertility in approximately 20% to 30% of affected women due to complications related to the immune system.
   • Untreated Sexually Transmitted Infections (STIs): Infections like chlamydia and gonorrhoea can lead to pelvic inflammatory disease in up to 10% of women, potentially causing lasting damage to the fallopian tubes.
   • Lifestyle Factors: Obesity can interfere with hormone levels and ovulation, with studies indicating that overweight women may face a 20% to 40% increased risk of infertility. Additionally, excessive alcohol consumption and smoking can adversely affect egg quality and heighten the risk of miscarriage. Even high levels of stress can negatively impact reproductive health by causing hormonal disruptions that may disrupt ovulation.

While these are the most common causes, they are not definitive. In some cases, the cause of infertility is never found. A combination of several minor factors in both partners could contribute to unexplained fertility problems. Although it can be frustrating to lack a specific diagnosis, this issue may resolve itself over time. However, it is important not to delay seeking infertility treatment.

Symptoms of Female Infertility

Often, female infertility presents no overt symptoms other than the inability to conceive after trying for a year. However, underlying conditions may manifest through absent or irregular menstrual cycles that are either too long (35 days or more) or too short (less than 21 days), indicating ovulation issues.

4 Risk Factors for Female Infertility  

Several risk factors can elevate a woman’s likelihood of experiencing infertility, impacting her ability to conceive. Understanding these factors is essential for women planning to start a family or those who may be struggling with infertility.

1. Age: As mentioned above, age is one of the most significant risk factors associated with infertility. As women age, particularly after 35, their fertility potential declines sharply. This decrease is attributed to a reduction in both the quantity and quality of eggs. By the time women reach 40, the chances of conceiving naturally can drop to around 5% per cycle. Additionally, older age is often linked to an increased risk of chromosomal abnormalities in eggs, which can lead to miscarriage or genetic disorders in the child.
2. Obesity: Excess weight can profoundly affect a woman’s reproductive health. Obesity disrupts hormonal balance, leading to conditions like polycystic ovary syndrome (PCOS), which can inhibit ovulation. Research shows that overweight women may face a 20% to 40% higher risk of infertility compared to those with a healthy weight. Furthermore, obesity can increase the likelihood of complications during pregnancy, such as gestational diabetes and preeclampsia, making it even more critical to address weight management when considering conception.
3. Smoking and Alcohol Consumption: Both smoking and excessive alcohol intake have been shown to impair fertility. Smoking can damage the fallopian tubes, reduce egg quality, and affect hormone production, while alcohol can interfere with ovulation and hormonal balance.
4. Chronic Stress: While chronic stress may not directly cause infertility, it can exacerbate existing fertility issues. Stress can lead to hormonal imbalances that affect ovulation and menstruation, making it harder for women to conceive. Moreover, high stress levels can contribute to unhealthy lifestyle choices, such as poor diet and lack of exercise, which may further impact fertility. Engaging in stress-reducing activities like yoga, meditation, and counselling can help improve overall well-being and potentially enhance fertility.
5. Sexual History: A history of sexually transmitted infections (STIs) like chlamydia and gonorrhoea can lead to damage in the fallopian tubes, which may affect fertility. Engaging in unprotected sex with multiple partners raises the likelihood of contracting STIs, potentially resulting in fertility issues down the line. If you suspect you may have STIs, please consult a sexologist today to understand your treatment plan.

7 Ways to Diagnose Female Infertility

If you have been trying to conceive unsuccessfully for over a year, it’s advisable to undergo a comprehensive diagnostic evaluation for female infertility. This process helps identify any underlying issues that may be affecting your ability to conceive and can guide the appropriate treatment options. Here are some of the key diagnostic tests that may be recommended by a gynaecologist which includes:

1. Ovulation Testing: Ovulation testing typically involves blood tests to measure hormone levels, particularly those of luteinizing hormone (LH), follicle-stimulating hormone (FSH), and progesterone. These hormones play critical roles in the ovulation process, and abnormalities in their levels can indicate issues with ovulation. In some cases, at-home ovulation predictor kits may also be used to track ovulation cycles
2. Hysterosalpingography (HSG): Hysterosalpingography is a specialised X-ray procedure that evaluates the shape of the uterus and checks for blockages in the fallopian tubes. During this test, a contrast dye is injected into the uterus through the cervix, allowing the doctor to visualise the reproductive tract. If the fallopian tubes are open, the dye will flow through them, indicating that there are no obstructions. This test can also help identify uterine abnormalities, such as fibroids or polyps
3. Ovarian Reserve Testing: Ovarian reserve testing assesses the quantity and quality of a woman’s eggs, providing insight into her reproductive potential. This can be done through blood tests measuring levels of FSH and estradiol on specific days of the menstrual cycle, as well as an ultrasound to count the number of follicles in the ovaries. Other tests, such as the anti-Müllerian hormone (AMH) test, may also be used to evaluate ovarian reserve.
4. Imaging Tests: Imaging studies, such as ultrasounds or magnetic resonance imaging (MRI), can help identify uterine or ovarian abnormalities that might affect fertility. A transvaginal ultrasound is often the first imaging test used, as it provides detailed images of the ovaries and uterus. An MRI can offer more detailed views and help diagnose complex conditions, such as endometriosis or structural abnormalities.
5. Laparoscopy and Chromotubation: In some rare cases, a laparoscopy might be suggested. This is a minimally invasive surgery where the doctor can look directly at the organs in the pelvis, like the ovaries and fallopian tubes, to check for problems such as endometriosis (where tissue grows outside the uterus), scar tissue, or fibroids. If any issues are found, the doctor can sometimes fix them during the procedure. During the laparoscopy, a test called chromotubation may be done. This involves injecting a special dye through the cervix, which helps the doctor see if the fallopian tubes are open or blocked. If the dye passes through the tubes and out the ends, it confirms the tubes are working properly. A hysteroscopy, which is another type of test, is often done at the same time to check for growths or issues inside the uterus.
6. Hormonal Assessments: In addition to ovulation testing, hormonal assessments may include tests for thyroid function and prolactin levels. Thyroid imbalances can significantly affect menstrual cycles and fertility, while elevated prolactin levels may interfere with ovulation.
7. Genetic Testing: For women with a family history of genetic disorders or repeated pregnancy loss, genetic testing may be suggested. This can help identify chromosomal abnormalities that could affect fertility or pregnancy outcomes.

Treatment of Female Infertility

The infertility treatment for females depends on the underlying cause. Common options include:

1. Medications: Clomiphene citrate or letrozole may stimulate ovulation.
2. Surgery: Correcting structural problems in the reproductive organs, such as fibroid removal.
3. Assisted reproductive technology (ART): Procedures like in vitro fertilisation (IVF) offer hope for many women, especially when other treatments fail.
4. Lifestyle changes: Adopting a healthier diet, managing stress, and engaging in regular exercise may serve as natural ways to increase female fertility.

When to See a Doctor

If you’re a woman under 35 and have been trying to conceive for a year without success, it’s time to consider seeking medical advice. For those over 35, it’s recommended to consult a doctor after six months of trying. Additionally, if you’ve experienced painful periods, irregular cycles, or any reproductive health concerns, reaching out to a specialist sooner can provide valuable guidance and support.

Living with Infertility

Navigating the path of infertility can be an emotionally draining journey, filled with hope and heartache. It’s essential to acknowledge your feelings and seek support during this time. Lean on loved ones who can offer comfort, or consider connecting with mental health professionals and infertility support groups who understand your struggles.

Taking care of your emotional well-being is just as important as addressing physical health. Engage in activities that bring you joy, practice self-care, and find ways to manage stress. Remember, you’re not alone in this journey, and seeking support can help you maintain both your mental and physical health as you navigate these challenges.

Female infertility is a complex and deeply personal issue that affects many women. Fortunately, advances in medicine have made it possible to diagnose and treat many causes of infertility, offering hope to those longing for a family. Understanding the symptoms, causes of infertility in women, and available treatments can empower women to seek the right care at the right time. If you’re facing fertility challenges, remember that help is available, and you are not alone.
