Top 10 Causes of Difficulty in Conceiving for Women

Chemical exposure accounts for 29% of all factors contributing to difficulty in conceiving. These chemicals are environmental pollutants, pesticides, and industrial chemicals. Women are not the only ones affected by this cause; men who are exposed to harmful chemicals, especially in gold mining areas or electronics factories, also face fertility issues. Some chemicals, like phthalates and furans, are known to impede conception. While the benefits of chemicals are undeniable in modern industrial production, their downside is significant. Chemicals can harm human reproductive health, a concern especially for people working with hazardous industrial substances. Recent studies show that long-term exposure to low levels of benign chemical mixtures in everyday environments can lead to reproductive risks, such as reduced egg production, miscarriage, sperm abnormalities, and lower sperm counts. These chemicals can even affect the fetus in utero, potentially causing infertility later in life.

Smoking has negative effects before, during, and after pregnancy. Smoking not only harms the development of the fetus but can also lead to infertility. Cigarette smoke causes changes in certain hormones and damages DNA in both women and men. Women are affected by smoking during pregnancy whether they smoke directly or are exposed to secondhand smoke. To have a baby, it is crucial for the family to eliminate all cigarette smoke.

Studies show that in the United States, approximately 11.4% of pregnant women smoke. Women who smoke regularly find it harder to conceive. Stopping smoking as soon as pregnancy is confirmed (or at least during the first three months) increases the chances of having a healthy baby. While quitting smoking during pregnancy can be challenging, it is vital to quit before conception. Quitting may not be easy, but there are strategies that can help, such as consulting with a doctor, joining a smoking cessation program, or calling a quitline. These are practical ways to stop smoking and improve the chances of a successful pregnancy.

A study from the Norwegian University of Science and Technology (NTNU) demonstrated that the body may not have enough energy to support both intense exercise and pregnancy. Whether you're a professional athlete or someone who enjoys high-intensity workouts and is trying to conceive, a long period of unsuccessful attempts could signal a need to adjust your exercise routine. According to research from NTNU, in such cases, reducing workout intensity may increase the chances of conception. About 7% of women in Norway experience infertility, unable to conceive within the first year of trying. However, after this period, they are often able to conceive normally.

There are many factors that contribute to infertility, including medical and lifestyle-related causes such as smoking, stress, alcohol consumption, and being underweight or overweight. It is well known that female athletes who engage in intense physical training face more reproductive issues than other women. However, it remains unclear whether excessive physical activity affects the fertility of non-athletic women. Researchers at NTNU found the answer through a study involving nearly 3,000 women, revealing that excessive and frequent exercise can reduce fertility in young women. Fortunately, this effect occurs primarily when they exercise too intensely.

The choice of contraceptive methods and how they are used is a personal decision for each individual. Healthcare professionals can provide guidance and advice on which method is most suitable and effective for each person to ensure safe and effective contraception. While most contraceptive methods are highly effective when used correctly, no method offers 100% protection. Consulting with a healthcare provider and discussing options with your partner is essential to making the best decision.

If you use hormonal birth control pills, you may become pregnant within a month after stopping. However, if you use injectable contraceptives or contraceptives in liquid form, it may take 12-14 weeks before you can conceive. In many cases, it may take a year or longer to conceive after discontinuing these methods. If your doctor has advised you to stop using birth control, it is important to follow that advice as it may affect your future fertility.

Individuals with infections such as chlamydia and gonorrhea are more likely to face difficulty in conceiving. The bacteria causing chlamydia can lead to fallopian tube inflammation in women. Many women remain unaware of having these infections until they struggle to conceive and undergo medical tests, only then discovering the underlying issue. For the well-being of your family, couples should regularly screen for sexually transmitted infections (STIs) to ensure early treatment and intervention.

Especially for individuals with a history of sexually transmitted diseases, regular screening is essential to maintain health. Screening is recommended every three months, but even if there is no perceived risk, don't skip blood tests advised by your doctor. It's also important to visit your doctor if you experience symptoms of vaginal infections such as sores, foul-smelling discharge, lower abdominal pain, a burning sensation while urinating, or persistent itching.

Modern women often juggle multiple roles, balancing work and social activities, which can lead to frequent stress and discomfort. High levels of stress can alter hormone levels, making ovulation more difficult. If you are trying to conceive, it is essential to ensure you are relaxed and at ease. While stress alone is unlikely to cause infertility, it can lead to unhealthy behaviors that negatively impact fertility. For instance, stress can result in insomnia.

If your work schedule or lifestyle demands that you stay up late or wake up frequently during the night, the resulting chronic sleep deprivation can affect your body and, consequently, your reproductive health. Studies on night-shift workers show that working late into the night, especially close to ovulation, can increase the risk of miscarriage and cause irregular menstrual cycles in some women. Irregular cycles are a known risk factor for fertility problems. Therefore, getting adequate sleep at night and avoiding night shifts (if possible) can help improve your chances of conception.

Researchers analyzed data from 413 women aged 19 to 41 over a four-year period, tracking up to 19 menstrual cycles. These women reported daily the amount and type of alcohol they consumed. Additionally, researchers collected information on factors such as age, medical history, smoking, obesity, contraceptive use, and pregnancy intentions. These women also provided urine samples on the first and second day of each menstrual cycle to determine pregnancy status.

The researchers discovered that drinking alcohol at any stage of the menstrual cycle significantly reduced the chances of conception compared to those who did not drink alcohol. Specifically, consuming more than six drinks per week, moderate consumption of three to six drinks weekly, and binge drinking of four or more drinks in a single day all led to lower conception rates. One drink equals 355 ml of beer, 148 ml of wine, or 44 ml of spirits. In the luteal phase, which is the last two weeks of the menstrual cycle before menstruation begins, and when implantation occurs, not only heavy drinking but even moderate drinking reduced the chances of conception by approximately 44% compared to those who did not consume alcohol.

This is one of the least recognized causes, as it is not often discussed in daily life. Being overweight hinders hormone production in women, making it harder to conceive, and when women become excessively obese, ovarian function can deteriorate. Obesity in women is a chronic condition marked by excessive and abnormal fat accumulation, often tied to nutrition and metabolism. Beyond the risks to the woman's health, obesity has significant impacts on the fetus right from the early stages of embryonic development. There are five key effects on fertility and embryonic growth when women are obese. Firstly, obesity makes it harder for women to conceive. Obesity symptoms in women manifest in the reproductive system, such as irregular menstrual cycles, and is closely linked to polycystic ovary syndrome, insulin resistance, and disturbances in normal egg development and ovulation. Additionally, women's 'overweight' status can make it difficult for eggs to be fertilized and implant normally.

For obese women, the risk of embryo death is higher. Obesity increases the risk of infections, reduces egg and embryo viability, and changes the environment that supports egg development. In individuals with excessive body fat, metabolic and hormonal imbalances are significant, particularly with elevated levels of male hormones. These disruptions can severely affect egg health, ultimately damaging the fertilization process. Furthermore, obesity increases obstetric complications, including the risk of birth defects, preeclampsia, stillbirth, hypertension, cardiovascular issues, and diabetes. Therefore, women need to manage their body weight, especially during pregnancy, as obesity can hinder the healthy development of the baby and increase the likelihood of the child developing health issues after birth.

Body weight has a significant impact on reproductive health for both genders. For women, both being overweight (obese) and underweight (too thin) can disrupt the reproductive system, leading to hormone imbalances, menstrual irregularities, and difficulty conceiving. In fact, for women seeking in vitro fertilization (IVF), weight is one of the major challenges. If you are too thin, your body may not have enough nutrients to maintain overall health or regulate internal processes effectively. Blood circulation may be impaired, preventing proper blood flow to the reproductive organs, leading to menstrual irregularities and limiting the production of estrogen necessary to strengthen the uterine lining and produce cervical mucus. These insufficient conditions indicate that your body is not prepared for conception.

When you are too thin, the levels of hormones produced by your body are often too low to adequately support the uterine lining for conception. Moreover, the menstrual cycles of underweight women tend to be irregular, making it difficult to predict ovulation. Additionally, individuals with unhealthy body weight, especially those severely underweight, may suffer from significant deficiencies in vital nutrients such as vitamin D and calcium. Similar to obesity, underweight individuals may also face a higher risk of cardiovascular diseases, osteoporosis, and other health conditions, which can further complicate fertility. Therefore, if you are hoping to conceive, it is crucial to maintain a healthy weight. Regular health check-ups are essential to ensure that, even if you are thin, your health remains optimal, with no nutrient deficiencies and proper bodily functions. Only then can you determine if your body is ready for pregnancy and childbirth.

Every woman is born with a finite number of eggs produced in her ovaries. However, as age increases, the eggs undergo aging and their quantity and quality decrease. Every woman knows that as they get older, the ability to conceive becomes more challenging. Depending on individual factors, the decline in female fertility may happen at different times, but it generally occurs in the early to mid-30s. The exact timing is unpredictable. Some women may lose their fertility years before the first signs of menopause appear. Therefore, if you are planning to have children, consider trying to conceive before the age of 35.

There are two common reasons for the decline in female fertility. First, problems during ovulation become more frequent with age. This occurs because fewer high-quality eggs remain, making conception more difficult. Additionally, egg quantity decreases with age. Some women experience early menopause, even ceasing ovulation before the age of 40. Your cycle may become irregular, with periods becoming shorter or longer as you approach menopause, which makes ovulation more unpredictable. Second, long-term infections can cause blocked fallopian tubes. Many women unknowingly suffer from conditions that cause tubal obstruction from a young age. Over time, these conditions can lead to inflammation, making it harder to conceive. For example, untreated bacterial infections like chlamydia can develop into pelvic inflammatory disease, which can block the fallopian tubes. This not only prevents fertilization but also increases the likelihood of an ectopic pregnancy.
