Fertility is a topic surrounded by hope, uncertainty, and plenty of myths. Many Canadians who are trying to conceive quickly encounter well-meaning advice from friends, family, and the internet—but not everything you hear is backed by science. In this article, we take a closer look at some of the most common fertility myths and separate fact from fiction.

Myth 1: You can get pregnant at any time in your cycle

One of the most persistent misconceptions is that pregnancy can happen at any point in a woman’s menstrual cycle. In reality, there’s only a short window when conception is possible—around ovulation, which typically occurs about 14 days before the next period.

An egg can be fertilized for up to 24 hours after ovulation, while sperm can survive in the reproductive tract for up to five days. This means that intercourse in the days leading up to ovulation can also result in pregnancy. Tracking your cycle or using ovulation tests can help identify your most fertile days.

Myth 2: Age only matters for women

It’s true that women’s fertility declines significantly with age—especially after 35—but men’s age matters too. Sperm quality can decrease over time, and the risk of genetic changes in sperm increases with age. This can affect both the chances of conception and the health of the baby.

While men can often father children later in life, research shows that fertility outcomes are generally best when both partners are under 35. That doesn’t mean it’s impossible later on, but it may take longer and require more planning or medical support.

Myth 3: Stress prevents pregnancy

Stress is often blamed when conception doesn’t happen right away. While severe, chronic stress can disrupt hormone balance and ovulation, there’s no solid evidence that everyday stress alone prevents pregnancy.

That said, stress can still play an indirect role. It can affect sleep, energy levels, and relationships—all of which can make the process more challenging. Finding ways to manage stress, such as through exercise, mindfulness, or counselling, can support both emotional well-being and fertility efforts.

Myth 4: Lying with your legs up after sex helps you conceive

A classic piece of advice suggests lying with your legs up after sex to help sperm reach the egg. However, there’s no scientific proof that this position increases the chances of conception. Sperm move quickly toward the uterus, and most reach their destination within minutes.

What matters most is timing intercourse during the fertile window—not what position you’re in afterward. If resting for a few minutes feels comfortable, there’s no harm, but it’s not necessary for conception.

Myth 5: A healthy lifestyle guarantees fertility

Eating well, exercising, and limiting alcohol are all beneficial for reproductive health—but they don’t guarantee fertility. Factors like age, genetics, and underlying medical conditions also play major roles.

For women, being significantly underweight or overweight can disrupt hormone balance and ovulation. For both men and women, smoking and heavy alcohol use can reduce fertility. A healthy lifestyle improves your chances, but it can’t override biological limits.

Myth 6: If it doesn’t happen within a few months, something’s wrong

It’s completely normal for conception to take time. Even for healthy, fertile couples, the chance of pregnancy in any given cycle is only about 20–25%. Most couples conceive within a year, but for some, it takes longer without any underlying problem.

In Canada, doctors generally recommend seeking medical advice if you’ve been trying for a year without success—or after six months if the woman is over 35. A fertility assessment can help identify any issues and guide next steps.

Myth 7: Fertility treatments always work

Fertility treatments can be life-changing, but they’re not a guaranteed solution. Success rates depend on factors such as age, the cause of infertility, and the type of treatment. For women under 35, the success rate for one IVF cycle is typically around 30–40%, but it decreases with age.

It’s important to have realistic expectations and to discuss options thoroughly with your healthcare provider. Some couples need multiple attempts, and others may combine medical treatment with lifestyle changes or complementary therapies—though evidence for alternative methods remains limited.

Navigating the myths

Fertility is a complex interplay of biology, lifestyle, and emotion. Myths often arise because people want explanations and control in a process that can feel unpredictable. The best approach is to rely on credible sources, communicate openly with your doctor, and remember that every journey is unique.

Knowing the difference between myth and fact won’t guarantee a faster pregnancy—but it can bring clarity, confidence, and peace of mind along the way.
