    Understanding How Male Fertility Changes with Age


    Understanding How Male Fertility Changes with Age

    Updated on 19 September 2023

    Men and women have different fertility patterns and this difference is even more pronounced when the age of the person is taken into account. Male fertility declines with age while female fertility peaks in the early teens and late 20s and then declines steadily and rapidly. This article looks at how male fertility changes with age and the various factors that affect male fertility.

    What is male fertility?

    Male fertility is the ability of a man to father a child. It is determined by multiple factors such as sperm motility, count, morphology, and semen quality. A man's fertility can be affected by many different factors such as lifestyle, medical conditions, and age.

    Factors affecting male fertility

    There are many factors that can affect a man's fertility. These include:

    1. Lifestyle factors

    Lifestyle factors such as smoking, alcohol consumption, and drug use, as well as medical conditions such as diabetes, obesity, and hypertension.

    2. Environmental factors

    Environmental factors such as exposure to toxins, pesticides, and radiation also play a role.

    3. Age

    Age is also a major factor when assessing male fertility. As men age, their sperm count and motility decrease. This decrease in fertility is more pronounced in men over the age of 40.

    Understanding fertility by age

    It is important to understand the impact of age on male fertility. As men age, their fertility declines. The decline is more pronounced in men over the age of 40. This decline is attributed to a decrease in sperm count, motility, and semen quality.

    1. Fertility trends for men in their 20s

    For men in their 20s, their fertility is generally considered to be at its peak. The sperm count is high and the motility and morphology are also good. However, lifestyle factors can still have an impact on fertility. Smoking and excessive drinking can reduce sperm count, motility, and morphology. Exposure to environmental toxins and radiation can also have an impact.

    2. Fertility trends for men in their 30s

    Men in their 30s are still considered to be in their prime fertility years. However, the decline in fertility starts to become more pronounced in this age group. The decline is attributed to a decrease in sperm count and motility, as well as a decrease in semen quality.

    3. Fertility trends for men in their 40s

    By the time men reach their 40s, their fertility has decreased significantly. The decline is attributed to a decrease in sperm count, motility, and semen quality. The decline is more pronounced in men over the age of 40 than it is in men in their 30s.

    Impacts of lifestyle on male fertility

    Lifestyle factors can have a significant impact on male fertility. Smoking, drinking, and drug use can all decrease sperm count and motility, as well as reduce semen quality. Exposure to environmental toxins and radiation can also have an impact. Eating a healthy diet and exercising regularly can help to improve fertility.

    Common male fertility treatments

    If male fertility is an issue, there are a number of treatments available such as:

    1. Medications

    Medications are often used to treat male infertility caused by hormonal imbalances, low sperm count, or poor sperm motility. Examples include Clomiphene citrate, which stimulates the release of hormones needed for sperm production, and Human Chorionic Gonadotropin (hCG), which increases testosterone levels to improve sperm count and quality.

    2. Lifestyle Changes

    Adopting a healthy lifestyle can positively impact male fertility. This includes maintaining a balanced diet, regular exercise, avoiding excessive alcohol and tobacco consumption, managing stress levels, and maintaining a healthy weight. These changes can help improve sperm quality and overall reproductive health.

    3. Supplements and Ayurvedic Herbs

    Some supplements and Ayurvedic herbs may improve male fertility. Coenzyme Q10, zinc, selenium, and vitamin E are commonly recommended supplements to support sperm health. Ayurvedic herbs like Ashwagandha, Shilajit, and Tribulus terrestris are believed to enhance fertility by improving sperm count, motility, and quality.

    Men looking to boost their fertility can also try Mylo's Potenmax Testosterone Booster Capsules that are an effective blend of Omega-3 fatty acids, safed musli, ashwagandha, fenugreek and kaunch beej, among others. These ingredients can help improve sperm motility and quality, increase testosterone levels, enhance physical performance and boost energy and stamina.

    4. Assisted Reproductive Techniques (ART)

    ART involves procedures that help overcome fertility challenges. Intrauterine Insemination (IUI) is a common technique where washed and prepared sperm is directly inserted into the woman's uterus during ovulation. In vitro fertilization (IVF) is another option, where eggs and sperm are fertilized outside the body and then transferred to the uterus.

    5. Surgical Interventions

    In some cases, surgical interventions can help treat male infertility. Varicocelectomy is a procedure to repair or remove enlarged veins in the scrotum that can affect sperm production. Other surgeries may address blockages, such as vasectomy reversal or sperm retrieval from the testicles.

    Remember, the effectiveness of these treatments may vary depending on the underlying cause of infertility, and it's crucial to consult with a healthcare professional or a fertility specialist to determine the most appropriate treatment for individual cases.


    Male fertility is an important factor in the ability to conceive a child. As men age, their fertility declines. This decline is more pronounced in men over the age of 40. If you are concerned about your fertility, it is important to speak to your doctor.
