Infertility affects millions of people worldwide and can have a profound emotional impact on individuals and couples trying to conceive. While conversations about fertility have become more common in recent years, infertility remains a topic that many people find difficult to discuss.
World Health Organization (WHO) estimates that infertility affects approximately 1 in 6 people globally at some point during their reproductive years. Raising awareness helps reduce stigma, encourages earlier medical evaluation, and reminds those experiencing fertility challenges that they are not alone.
In this article, we’ll explore what infertility is, common causes, lifestyle factors that may influence fertility, and when it’s time to speak with a healthcare provider.

Infertility is generally defined as the inability to achieve pregnancy after:
Infertility can affect both women and men, and in some cases, both partners contribute to fertility challenges. Sometimes, despite comprehensive testing, no specific cause is identified.
Healthcare professionals often describe infertility as either:
Primary infertility – when pregnancy has never occurred.
Secondary infertility – when pregnancy has occurred previously but conceiving again becomes difficult.
Understanding the underlying cause is an important step toward identifying appropriate treatment options.
Female fertility depends on regular ovulation, healthy reproductive organs, balanced hormone levels, and overall health.
Some of the most common causes include:
Problems with ovulation are among the leading causes of infertility. Conditions such as Polycystic Ovary Syndrome (PCOS) can interfere with regular egg release, making conception more difficult.
Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus. The condition may affect the ovaries, fallopian tubes, and surrounding tissues, sometimes making pregnancy more challenging.
The fallopian tubes allow the egg and sperm to meet. Damage caused by previous infections, endometriosis, or pelvic surgery may reduce the chance of fertilization.
Female fertility naturally declines with age as both the number and quality of eggs decrease. While many women conceive naturally in their late 30s and beyond, pregnancy may take longer and the risk of miscarriage increases over time.
Certain chronic health conditions, including diabetes and thyroid disorders, as well as some cancer treatments, may affect fertility depending on the individual and the treatment received.
Infertility is not solely a women’s health issue. Male factors contribute to a significant proportion of infertility cases.
Common causes include:
Because fertility is a shared responsibility, healthcare providers often recommend evaluating both partners when pregnancy does not occur as expected.
Although not all causes of infertility can be prevented, healthy lifestyle habits may support reproductive health.
A diet rich in vegetables, fruits, whole grains, lean proteins, healthy fats, and fibre provides important nutrients that support overall health.
Rather than following restrictive diets, focus on sustainable eating habits that nourish your body.
Regular physical activity supports cardiovascular health, hormone balance, and healthy weight management.
You don’t need intense workouts to experience benefits. Activities such as walking, cycling, swimming, or strength training can all contribute to overall well-being.
Both being underweight and overweight may affect hormone levels and ovulation in some individuals.
If weight is a concern, speak with your healthcare provider about healthy, individualized approaches rather than pursuing rapid weight-loss plans.
Smoking has been associated with reduced fertility in both women and men.
If you’re planning a pregnancy, limiting alcohol consumption is also recommended. If you become pregnant or think you may be pregnant, current health guidelines recommend avoiding alcohol altogether.
Stress alone is not considered a direct cause of infertility, but chronic stress can affect sleep, eating habits, physical activity, and overall quality of life.
Practices such as mindfulness, exercise, journaling, or speaking with a counsellor may support emotional well-being during the fertility journey.
It’s important to seek medical advice if:
Early assessment may help identify underlying causes and provide access to appropriate treatment options sooner.
Learning more about your menstrual cycle is an important part of fertility awareness.
Tracking ovulation, cycle length, and menstrual patterns may help you recognize changes worth discussing with your healthcare provider. While cycle tracking cannot diagnose infertility, it can provide valuable information that supports reproductive health conversations.

Infertility affects millions of people, and every fertility journey is unique. While some causes of infertility cannot be prevented, understanding your reproductive health, maintaining healthy lifestyle habits, and seeking medical advice when needed can help you make informed decisions about your care.
Most importantly, remember that experiencing infertility is not a personal failure. Support, medical guidance, and treatment options are available, and many individuals and couples go on to build their families in different ways.
Primary infertility refers to difficulty becoming pregnant after never having conceived before. Secondary infertility occurs when someone has previously been pregnant but later experiences difficulty conceiving again.
Yes. Infertility can result from female factors, male factors, a combination of both, or causes that remain unexplained after testing.
Healthy habits such as eating a balanced diet, exercising regularly, maintaining a healthy weight, avoiding smoking, limiting alcohol, and managing stress can support overall reproductive health. However, they may not resolve all causes of infertility.
Tracking your menstrual cycle can help you identify ovulation patterns and recognize changes that may be useful to discuss with your healthcare provider. While it cannot diagnose infertility, it can support greater fertility awareness.
