Fertility Myths and Facts: What Can You Really Trust?
Fertility Myths and Facts: What Can You Really Trust?
Fertility is a topic surrounded by hope, anxiety, and plenty of myths. Couples trying to conceive often receive well-meaning advice from friends, family, and the internet – but not everything you hear is true. In this article, we take a closer look at some of the most common fertility myths and separate fact from fiction, with a focus on what’s relevant for readers in Ireland.
Myth 1: You can get pregnant at any time in your cycle
One of the most persistent misconceptions is that women can get pregnant at any point in their menstrual cycle. In reality, there’s only a short window when conception is possible – around ovulation, which usually occurs about 14 days before the next period.
An egg can be fertilised for up to 24 hours after ovulation, but sperm can survive in the female body for up to five days. This means that intercourse in the days leading up to ovulation can also result in pregnancy. Understanding your cycle and using ovulation tests can be helpful tools for those trying to conceive.
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 also plays a role. 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 is generally highest 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 quickly. While severe, long-term stress can affect hormone balance and ovulation, there’s no solid scientific evidence that everyday stress alone prevents pregnancy.
That said, stress can influence sleep, energy levels, and relationships – all of which can indirectly make it harder to conceive. Finding ways to manage stress, such as exercise, mindfulness, or talking to a counsellor, can be beneficial for overall wellbeing and fertility.
Myth 4: Lying with your legs up after sex helps you conceive
A classic piece of advice says you should lie with your legs up after sex to increase your chances of getting pregnant. However, there’s no scientific proof that this makes any difference. Sperm move quickly towards the uterus, and most reach their destination within minutes.
What matters most is timing intercourse during the fertile window – not your position afterwards. If you prefer to rest for a few minutes, that’s fine, but it’s not a requirement for conception.
Myth 5: A healthy lifestyle guarantees fertility
A balanced diet, regular exercise, and limiting alcohol are all beneficial for fertility – but they don’t guarantee it. Factors such as age, genetics, and underlying health conditions also play a major role.
For women, being significantly under- or overweight can affect hormone balance and ovulation, while smoking and heavy drinking can reduce fertility in both men and women. A healthy lifestyle improves your chances but can’t overcome all biological limitations.

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 around 20–25%. Most couples conceive within a year, but for some, it takes longer without there necessarily being a problem.
In Ireland, doctors generally recommend seeking 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 that might be treatable or supported medically.
Myth 7: Fertility treatment always works
Fertility treatments can be life-changing for many couples, but they’re not a guaranteed solution. Success rates depend on age, the cause of infertility, and the type of treatment. For women under 35, the chance of pregnancy after one IVF cycle is typically around 30–40%, but this decreases with age.
It’s important to have realistic expectations and to seek thorough medical guidance before starting treatment. Many couples need several attempts, and some choose to combine medical treatment with lifestyle changes or complementary therapies – though evidence for the latter remains limited.
Navigating the myths
Fertility is a complex interplay of biology, lifestyle, and emotion. Myths often arise because we crave explanations and control in a process that can feel uncertain. The best approach is to rely on trustworthy sources, talk openly with your GP or fertility specialist, and remember that every person’s 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.
