Common Myths about Male Infertility

Many people believe infertility relies primarily on the woman’s body, but male factors contribute to about 40-50% of all infertility cases​. Despite this, male infertility often goes undiscussed, leading to misinformation and stigma that could stop you from finding viable options for you or your partner to build a family. In this post, we will debunk common myths about male infertility and provide facts to encourage a more open conversation and earlier interventions regarding male reproductive health.

Myth: Infertility is always a woman’s problem

It is a common misconception that the female reproductive system is often at fault for infertility issues. This belief places unfair pressure on women to undergo extensive testing and treatments before male partners are even evaluated. The stigma around male infertility, combined with societal expectations, discourages many men from seeking fertility assessments early, leading to missed opportunities for timely intervention.

Fact: Male infertility is just as common

In reality, male infertility accounts for about 40-50% of all infertility cases in couples trying to conceive​. Male factors may involve low sperm count, poor sperm motility (movement), abnormal sperm shape, or blockages preventing sperm release. These issues can arise from genetic factors, medical conditions, infections, injuries, or lifestyle choices, all of which can impair reproductive function. 

Examples of Male Fertility Issues:

  1. Low Sperm Count (Oligospermia): defined as having fewer than 15 million sperm per milliliter of semen, which reduces the chances of fertilizing an egg, commonly caused by hormonal imbalances, infections, or exposure to heat or environmental toxins.
  2. Poor Sperm Motility (Asthenospermia): sperm must swim effectively to reach and fertilize the egg. Motility issues often result from lifestyle factors like smoking, alcohol consumption, or testicular damage​. 
  3. Abnormal Sperm Morphology (Teratospermia): this refers to sperm with irregular shapes, which may make it harder for them to penetrate the egg, commonly caused by infections, genetic conditions, or exposure to toxins can affect sperm development.
  4. Obstruction in the Reproductive Tract: blockages, such as those caused by previous infections or surgeries, can prevent sperm from mixing with ejaculate.

Infertility is a shared challenge, not one that women face alone. Men are encouraged to undergo fertility evaluations alongside their partner early in the process as soon as issues with implantation become apparent. These evaluations often include a semen analysis, which is non-invasive, quick, and provides crucial insights into sperm health. Addressing male fertility earlier can prevent delays and provide viable treatments sooner​. 

By normalizing fertility evaluations for men, couples can work together towards solutions and improve their chances of achieving pregnancy. Advances in reproductive medicine now provide many options to address male infertility, ensuring that men have access to the care and treatment they need to build their families.

Myth: "If I Fathered a Child Once, I Can’t Be Infertile Now"

A common belief is that once a man has fathered a child, his fertility is guaranteed for life. This myth can prevent men from considering fertility evaluations, even if conception is taking longer than expected with a new partner. Unfortunately, this misconception overlooks the fact that fertility can change over time due to a wide variety of factors.

Fact: Male fertility isn’t static

A man’s fertility does not remain the same throughout his life. Fertility and reproductive health can decline or change due to age, lifestyle factors, medical conditions, or environmental influences. Male fertility is dependent on several components, including the quantity, movement, and shape of sperm, which can deteriorate over time​. In fact, studies show that sperm quality can begin to decline after a man reaches his 40s, affecting both his ability to conceive and the health of the pregnancy​.

Male Fertility Issues that Can Develop Over Time:

  1. Age-Related Decline in Sperm Quality: as men age, sperm concentration, motility, and morphology may decrease, in turn increasing the risk of miscarriage and genetic abnormalities during pregnancy​.
  2. Varicocele: a varicocele is an enlarged vein in the scrotum that can develop later in life. It disrupts blood flow and increases the temperature in the testicles, impairing sperm production. Treatment options like surgery can improve fertility outcomes.
  3. Infections and Medical Conditions: sexually transmitted infections, diabetes, or testicular injuries can arise after previous fatherhood, compromising sperm health and production​.
  4. Lifestyle Changes and Environmental Exposure: smoking, weight gain, alcohol use, and exposure to toxins or heat (like frequent hot tub use) can significantly lower sperm count and quality over time​.

Even if a man has previously fathered a child, it’s important to stay proactive about fertility health, especially if conception is taking longer than anticipated with a second child. Semen analysis can provide updated insights into sperm health, and early evaluations can identify treatable issues like varicocele or hormonal imbalances. Just as women monitor their reproductive health, men should consider fertility check-ups a key part of their overall well-being.

Seeking help sooner rather than later can prevent unnecessary delays and provide couples with a better understanding of their fertility landscape. Advances in reproductive medicine and fertility treatments offer a variety of solutions, giving men many opportunities to take control of their fertility and future family planning​.

Myth: Male infertility isn’t affected by lifestyle

Many men believe, due to the stigma and lack of information surrounding the subject, that fertility is purely biological and not influenced by everyday habits or lifestyle choices. This myth can create a false sense of security, leading men to overlook behaviors that could negatively affect their sperm health. As a result, some may delay making important and informed lifestyle changes that could improve their fertility.

Fact: Lifestyle influences fertility

Just like in women’s reproductive health, male fertility is heavily influenced by lifestyle choices. These factors play a crucial role in fertility, impacting the quality, quantity, and motility of sperm. Choices like smoking, alcohol consumption, stress management, and nutrition directly affect sperm production and overall reproductive health, even after implantation​. Sperm production is a dynamic process, and it takes around 72 days for new sperm to fully mature. This means that even short-term habits—like exposure to high heat or excessive drinking—can have lasting effects on fertility outcomes.

Examples of Lifestyle Factors Impacting Fertility:

  1. Smoking: smoking reduces sperm concentration and can cause DNA fragmentation, decreasing the chances of fertilization.
  2. Alcohol Use: excessive alcohol consumption has been linked to reduced testosterone levels and lower sperm production​.
  3. Poor Nutrition or Lacking Diet: excess weight can alter hormone levels, leading to reduced sperm count and motility. Additionally, diets lacking key nutrients (such as zinc, folate, and antioxidants) can impair sperm health​.
  4. Heat Exposure: frequent use of hot tubs, saunas, or even tight clothing can increase scrotal temperature, negatively affecting sperm production. Long-term exposure to heat in work environments (like in factories or kitchens) can also have a similar impact​.
  5. Chronic Stress: stress triggers the release of cortisol, which can interfere with testosterone production, affecting both libido and sperm quality​.
  6. Substance Use: recreational drug use, such as marijuana or anabolic steroids, can disrupt sperm production and quality by altering hormone levels and damaging testicular function​.

The good news is that many of these factors are within control. Making healthier choices—such as quitting smoking, moderating alcohol consumption, eating a balanced diet, and managing stress—can significantly improve fertility outcomes within a few months. Because sperm regenerates every 2-3 months, even small changes can lead to noticeable improvements in semen quality over time​.By understanding the link between lifestyle and fertility, men can take proactive steps to optimize their reproductive health. Early evaluations, paired with positive lifestyle changes, offer the best chance for success, whether through natural conception or assisted reproductive technologies.

Myth: Male infertility isn’t as treatable as female infertility

Many men believe that once diagnosed with infertility, there are no effective solutions available. This myth can create feelings of hopelessness and prevent men from seeking medical advice or exploring fertility treatments. Given the discourse around infertility focuses on women, so does the conversation on possible treatments and medical advances. The stigma associated with male infertility may also discourage the pursuit for other options, reinforcing the belief that nothing can be done. 

Fact: Infertility can be treated!

The reality is that many cases of male infertility are treatable. Depending on the underlying cause, treatments range from lifestyle changes to medical interventions, and assisted reproductive technologies offer effective solutions even in severe cases. Addressing male infertility can significantly improve the chances of conception, both with natural methods or through assisted fertility treatments​.

Examples of Treatment Options for Male Infertility:

  1. Lifestyle Modifications: stopping smoking, reducing alcohol intake, managing stress, and maintaining a healthy weight can improve sperm quality and motility. Sperm production cycles last around 72 days, meaning changes can show results within a few months​.
  2. Medical Interventions:
    • Hormonal Therapy: When infertility is linked to hormonal imbalances (such as low testosterone), doctors may prescribe medications to restore hormone levels and improve sperm production​.
    • Surgical Procedures: Conditions like varicocele can impair sperm production. This surgery has been shown to improve sperm quality and increase the likelihood of conception.
  3. Assisted Reproductive Technologies:
    • Intrauterine Insemination (IUI): For men with mild sperm abnormalities, IUI allows doctors to place concentrated sperm directly into the uterus to increase the chances of fertilization.
    • In Vitro Fertilization (IVF) with Intracytoplasmic Sperm Injection (ICSI): For severe cases, ICSI involves injecting a single sperm directly into the egg, bypassing common fertility barriers​.
  4. Sperm Retrieval Techniques: in cases of obstructive azoospermia (absence of sperm in the ejaculate), sperm can still be retrieved directly from the testicles or epididymis for use in assisted reproductive procedures like IVF-ICSI​.

A diagnosis of male infertility is not the end of the road but the beginning. With modern medical advancements, many conditions affecting male fertility can be treated or managed effectively. Fertility specialists work closely with patients to create personalized treatment plans, offering hope for conception even in challenging cases. Men are encouraged to seek evaluations early: the sooner potential issues are identified, the more treatment options become available.

Whether through lifestyle changes, medical treatment, or assisted reproduction, men have numerous paths to becoming fathers. With the right support and guidance, the journey toward parenthood is very much within reach​.

Empowering Men to Take Charge of Their Fertility

Infertility is not just a woman’s challenge—it’s a shared journey. Breaking down the myths surrounding male infertility is crucial for creating a more informed and supportive environment for couples trying to conceive. Male infertility is more common than many realize, but with early evaluations, lifestyle changes, and advanced medical treatments, there are effective ways to overcome it​.

Men are encouraged to seek fertility assessments early and embrace the opportunity to take proactive steps toward improving their reproductive health.
