Age and Fertility: What Changes and How to Cope with Anxiety

What changes in fertility with age?

Age is one of the most important factors in fertility, for both women and men. This does not mean that getting pregnant becomes impossible over time, but the body does change and, in many cases, the chance of conceiving decreases and it may take longer to achieve a pregnancy.

In women, the number and quality of eggs gradually decline over time. Fertility is usually highest in the late teens and early adult years, and begins to fall more clearly after 30, with a sharper drop from 35 onwards. After 40, the chance of natural pregnancy is even lower, and the risk of some pregnancy complications also increases.

In men, age can also affect fertility, although often more gradually. There may be a reduction in sperm quality, sperm motility, and an increase in the time needed to achieve pregnancy. The impact may be smaller than in women, but it should not be ignored.

Why does age matter so much?

Over time, the body naturally changes. In women, ovarian reserve decreases and cycles may become less regular. This does not mean ovulation suddenly disappears, but it does mean there are fewer eggs available and, on average, a higher chance of chromosomal changes.

Age can also bring other factors that affect fertility, such as endometriosis, fibroids, polycystic ovary syndrome, thyroid problems, excess weight, smoking, ongoing stress, or certain chronic conditions.

In men, age can affect sperm production and quality, and some lifestyle habits also matter: smoking, excess alcohol, obesity, sedentary habits, excessive heat around the testicular area, and exposure to certain substances.

Is there a right age to get pregnant?

There is no perfect age for everyone. The decision depends on health, life circumstances, emotional stability, the couple’s relationship, financial situation, and family plans. For some people, motherhood or fatherhood happens early; for others, later. What matters is having realistic information and, whenever possible, planning with medical support.

If having a child is not for now, it may be helpful to speak with a doctor about fertility, reproductive health, and future options. In some cases, it may make sense to assess ovarian reserve, review medication, treat health problems, or discuss fertility preservation.

When should you seek medical help?

It is advisable to seek help if the couple has been trying to conceive for some time without success. As a general guideline, an assessment is recommended after 12 months of regular attempts when the woman is under 35. If the woman is 35 or older, assessment should happen sooner, after around 6 months. If there are irregular cycles, severe pelvic pain, a history of endometriosis, repeated miscarriages, known medical conditions, or concern about male fertility, the assessment can and should happen earlier.

In Portugal, the first step may be through the family doctor, a gynaecologist, a urologist, or a fertility medicine appointment, depending on the situation. The sooner there is clarity, the less time is lost in anxiety and uncertainty.

What can be assessed?

Fertility testing may include hormone blood tests, ultrasound, ovulation assessment, semen analysis, and investigation of conditions that affect conception. The problem is not always clearly on the female or male side. In many couples, it is important to assess both partners.

It is also possible to identify simple factors that can be improved: having regular intercourse during the fertile window, stopping smoking, reducing alcohol, improving sleep, managing weight, and following up chronic conditions.

How can you cope with anxiety while trying to conceive?

Anxiety is very common. Trying to conceive can become emotionally demanding, especially when time passes, expectations grow, and each period feels like a disappointment. Many people feel guilt, shame, comparison with other families, and fear that it is “too late”.

The first step is to recognise that this anxiety is part of many people’s experience. It does not mean weakness or lack of faith. It means the desire to be a mother or father matters deeply. Validating what you feel is a start.

It helps to reduce exposure to things that increase pressure, such as invasive conversations, social media posts about pregnancies all the time, or excessive internet searching. Useful information matters; too much information and self-diagnosis usually increase fear.

It can also help to set specific moments to talk about the subject as a couple, instead of letting fertility take over every day. When the process is shared by two people, it is essential that both can express sadness, hope, fear, and tiredness without blame.

Practical strategies to ease the pressure

• Keep a reasonably stable routine for sleep, food, and exercise.
• Avoid turning each cycle into a test of success or failure.
• Use health professionals for specific questions.
• Try simple breathing, relaxation, or meditation techniques, if that feels right for your family.
• Talk to someone you trust who knows how to listen without minimising.
• Keep enjoyable activities in your life outside the fertility topic.

If anxiety is affecting your sleep, work, relationship, or daily wellbeing, it may be helpful to seek psychological support. Infertility and uncertainty can trigger prolonged stress, and caring for mental health is also part of the journey.

What should you say to someone going through this?

Often, the person needs less advice and more presence. Simple phrases like “I’m here”, “you don’t have to go through this alone”, or “it makes sense that you are tired” can be more helpful than trying to find quick solutions.

Avoid comments like “just relax and it will happen”, “just stop thinking about it”, or “I know someone who got pregnant at 45”. Even when well intended, these phrases can increase frustration.

And when spirituality helps?

For some families, faith, prayer, meditation, or being part of a religious community brings comfort, meaning, and hope during the process. For others, support comes more from personal reflection or family values such as patience, trust, and respect for each person’s timing. There is no single way to live through this wait. What matters is that each couple finds support in a calm way, without feeling pressured.

Fertility and age: what is important to remember?

The main message is simple: age influences fertility, but it does not determine a couple’s future on its own. There are things we cannot control, but there is also a lot that can be observed, cared for, and treated. Seeking help early, when needed, avoids prolonged suffering and makes it possible to make informed decisions.

If you are trying to conceive and feel anxious, know that you are not alone. Asking for medical clarification and emotional support is not an overreaction. It is a way of caring for your body, your relationship, and your family plans with more calm and confidence.
