Do Men Have Biological Clocks — What Is a Biological Clock?

When it comes to the topic of fertility, discussions often revolve around women and their biological clocks. However, it is important to recognise that men also have biological clocks that can impact fertility. In this blog, we will explore the concept of male fertility, as well as male infertility, and shed light on whether men have biological clocks.

What is a Biological Clock?

The term "biological clock" refers to the natural decline in reproductive potential as individuals age. In women, this decline is well-known and is primarily associated with a decrease in egg quality and quantity. However, research suggests that men also experience a decline in fertility as they grow older.

The Impact of Age on Male Infertility

Unlike women who experience a clear-cut decline in fertility with age, men tend to have a more gradual decrease in reproductive potential. Nevertheless, studies have shown that advancing age can lead to various challenges for men trying to conceive:

  1. Decreased Sperm Quality: As men age, the quality of their sperm may decline. This can affect sperm count, motility (ability to swim) and morphology (shape). These changes can reduce the chances of successful fertilisation.
  2. Increased Risk of Genetic Abnormalities: Advanced paternal age has been linked to an increased risk of genetic abnormalities in offspring. For instance, children born to older fathers may have higher rates of certain conditions like autism or schizophrenia.
  3. Reduced Sexual Function: Aging can also impact sexual function, including erectile dysfunction or a decrease in libido. These factors can hinder conception and lead to additional stress and emotional strain.

Promoting Male Fertility

While men may face challenges as they age, there are steps they can take to support their fertility:

  1. Lead a Healthy Lifestyle: Maintaining a healthy weight, exercising regularly, getting enough sleep, consuming fertility foods and managing stress can positively impact male fertility. Additionally, avoiding tobacco, excessive alcohol consumption and illicit drug use is crucial for reproductive health, as these habits increase the risk of male infertility.
  2. Regular Fertility Tests: Undergoing regular fertility tests can help identify any potential issues early on. These tests evaluate sperm count, motility, morphology as well as genetic factors that may affect fertility.
  3. Seek Medical Advice: Consulting with a fertility specialist is essential for couples struggling to conceive. A fertility specialist can assess both partners' fertility and provide personalised recommendations or treatment options tailored to their specific needs.
  4. Consider Fertility Preservation: For men who want to delay parenthood or anticipate potential future fertility issues, fertility preservation options such as sperm freezing can offer peace of mind.

In conclusion, the biological clock exists for men and can cause male infertility through factors such as decreased sperm quality, increased risk of genetic abnormalities and reduced sexual function with age. Adopting a healthy lifestyle, undergoing regular fertility tests, seeking medical advice and considering fertility preservation are vital steps for addressing concerns related to male infertility. Understanding and addressing male infertility is crucial for couples striving to conceive and build families.

Can a man's age affect the success rates of IVF procedure?

Yes, studies have shown that the success rates of IVF procedure may be lower when the male partner is older. Advanced paternal age can impact sperm quality and increase the risk of genetic abnormalities in embryos.

Is there an optimal age for men to conceive?

While there isn't a defined optimal age for men to conceive, it's generally recommended to start considering parenthood earlier rather than later. The chances of successful conception tend to decrease with age in both men and women.

How does lifestyle affect male fertility?

Unhealthy lifestyle choices such as smoking, excessive alcohol consumption, recreational drug use, obesity and sedentary habits can all negatively impact male fertility. Opting for a healthy lifestyle can significantly improve fertility potential.
