The Role of Male Age in Infertility: What You Need to Know
Infertility affects millions of couples worldwide, and while it is often assumed to be a female issue, male infertility plays a significant role as well. While the topic of male infertility is gaining more awareness, there is still limited knowledge and understanding around the impact of male age on fertility. In this blog post, we will delve into the role of male age in infertility and provide you with the information you need to know.
The Basics of Male Fertility
Before we dive into the effects of male age on fertility, it is essential to understand the basics of male fertility. The male reproductive system is responsible for producing and delivering sperm, which is necessary for fertilization to occur. Sperm production begins at puberty and typically continues throughout a man’s life. However, the quality and quantity of sperm can decline with age, affecting a man’s fertility.
Impact of Age on Sperm Quality
Research has shown that sperm quality declines with age. As men age, the number of healthy, motile sperm decreases, and the number of abnormally shaped or non-motile sperm increases. This decline in sperm quality can lead to difficulties with fertilization, making it harder for couples to conceive. A study published in the Journal of Urology found that men over the age of 40 had a 60% decrease in fertility compared to men under 30. Furthermore, men over the age of 45 had a 90% decrease in fertility.
Effects of Age on Sperm DNA
Apart from sperm quantity and quality, age can also impact the DNA of sperm. As men age, there is a higher risk of errors in the sperm DNA, which can lead to genetic abnormalities in offspring. These abnormalities can increase the risk of miscarriage, birth defects, and other health problems in children. A study published in the journal Fertility and Sterility found that men over the age of 35 had a significantly higher risk of having children with autism and schizophrenia.

Male Age and Time to Conceive
As men age, their reproductive hormones, such as testosterone and sperm production, decrease. This decline can lead to an increase in the time it takes to conceive. A study published in the journal Human Reproduction found that couples with a male partner over the age of 35 took five times longer to conceive than those with a male partner under 25. This longer time frame can cause stress and emotional strain on couples trying to conceive.
Fertility Treatments and Male Age
While fertility treatments such as in vitro fertilization (IVF) can help couples overcome fertility issues, male age can still play a role in the success rates of these treatments. Studies have shown that the success rates of IVF decrease with male age, with a decline of 11% for every five years of age. This decline is due to the decrease in sperm quality and DNA integrity mentioned earlier.
Factors That Can Affect Male Fertility
Apart from age, several other factors can affect male fertility. These include lifestyle choices, medical conditions, and genetics. Lifestyle choices such as smoking, excessive alcohol consumption, and drug use can all impact sperm quality and quantity. Medical conditions such as diabetes, hormonal imbalances, and sexually transmitted infections can also affect male fertility. Additionally, genetic factors can play a role in male infertility, with certain genetic conditions causing abnormalities in sperm production and function.
What Can You Do to Improve Male Fertility?
If you and your partner are trying to conceive, there are steps you can take to improve male fertility. Maintaining a healthy lifestyle, including a balanced diet, regular exercise, and avoiding harmful substances, can all contribute to better sperm quality. Seeking medical treatment for any underlying medical conditions and practicing safe sex can also help improve male fertility. It is also essential to be aware of the impact of male age on fertility and consider seeking fertility treatment earlier if needed.
In conclusion, male age plays a significant role in infertility, and it is essential to have a better understanding of its impact. As men age, their sperm quality, DNA integrity, and time to conceive can all be affected, making it harder for couples to conceive. While fertility treatments can help overcome some of these issues, it is crucial to be aware of the effects of male age on fertility and take steps to improve male fertility when trying to conceive.
