Parenthood is a dream shared by people all over the world. The ability to conceive and bring new life into the world is often considered a fundamental aspect of human existence. However, for a significant portion of the population, this dream is not easily realised due to infertility. Let us delve into the statistics and explore the question: What percentage of the population is infertile?

Defining Infertility

Before looking at the prevalence of infertility, it is essential to understand its definition. Infertility is typically defined as the inability to conceive after a year of regular, unprotected sexual intercourse. However, this definition may vary slightly depending on the source and context. It is important to recognise that infertility can affect both men and women, and it can have various causes, including physiological, genetic, hormonal, and environmental factors.

Global Infertility Statistics

Determining the exact prevalence of infertility globally is a complex task. Differences in data collection methods, cultural norms, and healthcare accessibility all affect the statistics. Nevertheless, various studies and organisations have attempted to provide estimates to shed light on the magnitude of the issue.


According to the World Health Organization (WHO), approximately 17.5% of the adult population experience infertility. This means that about 1 in 6 people face difficulties conceiving a child. These figures vary from region to region, with some countries reporting higher rates of infertility than others. Additionally, it's worth noting that the rates of infertility can fluctuate over time due to changing lifestyles, environmental factors, and advancements in medical technology.

Infertility Among Men And Women

Infertility affects both men and women, but the specific causes and prevalence may differ between the sexes. While women have traditionally been seen as the primary focus when discussing infertility, it is crucial to recognise that male infertility plays a significant role as well.

Approximately 40 - 50% of all infertility cases are due to male-factor infertility, while female infertility accounts for a similar percentage. The remaining cases are often classified as "unexplained" or result from combined male and female factors.

Factors Affecting Infertility Rates

Several factors influence the prevalence of infertility within a population. These factors include age, lifestyle choices, socioeconomic status, and access to healthcare. 


Fertility declines with age, particularly in women. Women are born with a finite number of eggs, and their quantity and quality diminish over time. As a result, the likelihood of infertility increases significantly after the age of 35.

Lifestyle Choices: 

Unhealthy lifestyle habits such as smoking, excessive alcohol consumption, poor nutrition, and obesity can negatively impact fertility in both men and women. Conversely, maintaining a healthy lifestyle can enhance fertility potential.

Socioeconomic Factors:

Socioeconomic status can also influence infertility rates. Limited access to healthcare, including reproductive services, can contribute to delays in seeking appropriate medical assistance and affect treatment outcomes.

Environmental Factors:

Exposure to environmental pollutants, toxins, certain medications, and radiation can potentially impair fertility in both men and women.


Treatment Options and Hope

Fortunately, medical science and technological advancements have provided various treatment options for infertility couples. Assisted reproductive technologies (ART), such as in vitro fertilisation (IVF), intrauterine insemination (IUI), and sperm/egg donation, have opened up possibilities for many individuals and couples to conceive. These techniques have significantly improved the chances of pregnancy, even for those with severe infertility issues.

Seeking Support

Infertility can be an emotionally challenging journey, impacting individuals and couples on multiple levels. The longing for a child, coupled with the stress and disappointment associated with infertility, can take a toll on mental well-being. It is crucial for individuals and couples struggling with infertility to seek emotional support through counselling, support groups, or online communities. Sharing experiences, seeking guidance, and connecting with others in similar situations can provide comfort and strength during this challenging period.

Infertility Is Worldwide

While pinpointing the exact percentage of the population affected by infertility is a complex task, it is clear that infertility is a significant global issue. Both men and women can experience infertility, with various factors influencing its prevalence. However, with advancements in medical technology and a range of treatment options available, there is hope for individuals and couples striving to overcome infertility.

Create Awareness

It is essential for society to promote awareness, understanding, and support for those struggling with infertility. By fostering a supportive environment and providing access to reproductive healthcare, we can contribute to a world where the dream of parenthood can be realized by more people, irrespective of the challenges they face along the way
