The Biological Dimension

It incorporates

1. body knowledge and its reproductive functions,
2. awareness of how risk factors such as age, lifestyle, and health behaviours affect fertility,
3. an understanding of the possibilities and limitations of reproductive technologies.

At the biological level, fertility literacy begins with understanding the body. Knowledge of the menstrual cycle, ovulation, hormonal changes, and sperm health allows individuals to recognise early signs that require medical attention.

Several risk factors can influence fertility, including:

• age,
• smoking and alcohol consumption,
• obesity or malnutrition,
• chronic stress,
• exposure to environmental toxins.

Recognising these factors helps people make healthier choices and seek timely medical advice.

Across Europe, fertility rates keep falling. Just 1,46 live births per woman in 2022 and even lower in Southern Europe, around 1,2 to 1,3. At the same time, the average age for having a first child has risen to almost 30.

This shift shows two sides of the same coin. Later parenthood often means more education, career freedom, and personal choice. But biology still matters. Fertility naturally declines with age, creating the “fertility gap”: the difference between how many children people hope for and how many they actually have.

The gap is not only biological. It reflects unequal expectations, limited support, and traditional gender roles that still shape life decisions. Without challenging these norms, we risk repeating the same inequalities that hold people back.

Fertility awareness also means knowing how the body works and when to ask for help. Age, smoking, stress, or other lifestyle factors can all affect reproductive health. Modern medicine offers many solutions for infertility, but it also has its limits. Assisted reproduction gives hope to many couples, yet its success rates decline with age.

Understanding fertility doesn’t mean turning life into a medical problem. It means learning to listen to your body, recognising risks early, and keeping realistic expectations about what medicine can and cannot do.

Myths and misconceptions remain common. From the idea that male fertility never changes to the belief that technology can fix everything. True fertility literacy is about learning the facts, but also questioning the stories we grow up with.

“Fertility is both fragile and resilient. A balance of biology, care, and context.”
