How to improve sperm quality and other male infertility questions - answered by fertility experts
What Affects Male Fertility
Scientific research has shed light on the various factors that influence male fertility. Understanding these elements can help individuals make informed decisions about reproductive health. Male fertility is shaped by a combination of medical conditions, lifestyle choices, and genetic factors, all of which can impact sperm production and quality.
Main Causes of Male Infertility
Hormonal imbalances are a major contributor to fertility challenges in men. When testosterone levels drop or other hormones become unbalanced, sperm production often suffers. Symptoms like fatigue, depression, weight gain, and lack of motivation can also accompany low testosterone levels.
Varicoceles, or enlarged veins in the scrotum, are another common issue. These veins create extra heat around the testicles, which can harm sperm production and quality. Many men remain unaware of this condition until fertility testing uncovers it.
Genetic conditions can also play a role. For instance, Klinefelter Syndrome disrupts hormone production, leading to reduced body hair and fertility problems. Another genetic condition, Kallmann Syndrome, affects both the development of sexual characteristics and the sense of smell, often resulting in infertility.
Physical trauma to the testicles, whether from injuries or medical procedures, can damage sperm production. Even seemingly minor injuries may have lasting effects on a man’s fertility.
Sperm Health: Count, Movement, and Shape
Male fertility is often assessed by examining three key sperm characteristics: count, motility, and morphology.
- Sperm count refers to the number of sperm in a semen sample. A low sperm count may present as watery or runny semen. A higher count increases the chances of successful fertilization.
- Sperm motility measures how effectively sperm move. Poor motility can prevent sperm from traveling through the female reproductive system to reach the egg, even if the sperm count is normal.
- Sperm morphology focuses on the shape and structure of sperm. Abnormal shapes may hinder the ability to penetrate the egg and can sometimes indicate genetic problems.
Issues with any of these factors - count, movement, or shape - can signal underlying fertility challenges.
Signs of Fertility Problems
Male fertility issues are often subtle, so recognizing potential warning signs is key to seeking timely help.
"Infertility is defined as no conception after 12 months of regular, unprotected intercourse. When it comes to male infertility, there are no other clear symptoms or signs."
- Dr. Amin Gorgy, Fertility Consultant, The Fertility and Gynaecology Academy
The main indicator of male infertility is the inability to conceive after a year or more of regular, unprotected sex.
Sexual function issues can also point to fertility challenges. Problems such as difficulty achieving or maintaining an erection, issues with ejaculation, or a reduced sex drive may stem from hormonal or physical conditions.
Physical symptoms in the testicular area, like pain, swelling, or lumps, should not be ignored. These could indicate conditions such as varicoceles, testicular torsion, or epididymitis, all of which can directly affect fertility.
Hormonal changes may also provide clues. Signs like reduced facial or body hair and abnormal breast tissue growth could signal hormonal imbalances impacting fertility.
Unexpected symptoms can sometimes reveal underlying fertility problems. For example, a loss of smell might point to Kallmann Syndrome. Similarly, frequent respiratory infections could be linked to conditions that affect reproductive health.
Male factors are involved in about 50% of all infertility cases, with men being the sole cause in 20% to 30% of situations.
How Lifestyle and Diet Affect Male Fertility
Everyday choices can have a direct impact on sperm health and testosterone levels. Studies show that male infertility plays a role in about 50% of couples facing fertility challenges. Many of these issues are tied to lifestyle factors that can be changed. The good news? Sperm quality can improve in just three months with targeted adjustments. Alongside these changes, a healthy diet can also make a big difference.
Habits That Hurt Fertility
Certain habits can take a serious toll on male fertility:
- Smoking and vaping: These introduce harmful chemicals that damage sperm DNA. Research published in BJU International highlights that smoking can cause irreversible DNA damage, lowering the chances of fertilization. A meta-analysis involving nearly 30,000 participants found that smoking reduces semen volume by 0.25 mL, total sperm count by 32.2 million/mL, and negatively affects sperm morphology and motility by 1.9%.
- Alcohol consumption: Even moderate drinking - just five drinks per week - can lower sperm quality. Heavier drinking may lead to testicular shrinkage, reduced libido, and changes in semen parameters.
- Obesity: Men with a body mass index (BMI) over 30 are three times more likely to experience reduced semen quality compared to those at a healthy weight. Alarmingly, the prevalence of obesity among young adults of reproductive age has quadrupled since the 1970s, contributing to declining fertility rates.
- Heat exposure: High temperatures around the testicles can disrupt sperm production. Dr. Saurabh Sethi explains that "High temperatures from these [hot tubs and saunas] can lower sperm count and quality because testicles need cooler temperatures to produce healthy sperm". Even a single prolonged heat exposure can affect sperm production for up to three months. Wearing tight underwear can also increase testicular heat, further impairing sperm production.
- Electronic device radiation: Keeping cell phones in pockets or laptops on laps exposes testicles to heat and electromagnetic radiation, which can reduce sperm motility by up to 8%.
- Recreational drug use: Substances like cannabis, opioids, and anabolic steroids can disrupt hormone levels, impair sperm production, and negatively affect sperm function and viability.
Foods and Nutrients That Help Fertility
On the flip side, a nutrient-rich diet can significantly support sperm health. Key nutrients include:
- Zinc: Found in oysters, beef, and pumpkin seeds.
- Selenium: Found in Brazil nuts and tuna.
- Folate: Found in spinach and legumes.
- Vitamin D3: Found in fatty fish and egg yolks.
- Vitamin E: Found in nuts and seeds.
- L-carnitine: Found in red meat and dairy.
A diet packed with fruits, vegetables, legumes, and fish is linked to better semen quality, while processed meats, excessive soy, high-fat dairy, trans fats, refined sugars, and foods with pesticides or BPA are associated with poorer sperm health.
Simple Lifestyle Changes
In addition to a balanced diet, small lifestyle tweaks can further boost fertility:
- Exercise and weight management: Regular physical activity and even modest weight loss can improve sperm quality and hormone levels. However, excessive endurance training should be avoided, as it may temporarily lower testosterone levels.
- Clothing choices: Opt for loose-fitting clothing to reduce heat around the testicles.
- Stress management: Techniques like meditation, exercise, or counseling can help restore hormonal balance and support testosterone production.
- Diet adjustments: Moving away from a Western diet, which is high in processed foods and simple carbs, can make a positive difference.
Since it takes about three months for the body to produce new sperm, staying consistent with these changes is essential for seeing measurable improvements in fertility markers.
Science-Backed Supplements for Male Fertility
While diet and lifestyle changes are the foundation for improving male fertility, supplements can serve as a helpful addition by addressing specific sperm health concerns. The key is selecting products with clinically proven ingredients in effective doses to target deficiencies directly.
How Sperm Worms Gummies Work
Sperm Worms gummies, developed by medical professionals Dr. Joshua Kovoor, MD, PhD, and Dr. Brandon Stretton, MD, PhD, are designed to support various aspects of male fertility. These pineapple-flavored gummies combine six well-researched ingredients - Zinc, Selenium, Folate, Vitamin D3, Vitamin E, and L-Carnitine - to improve sperm motility, morphology, count, and testosterone levels.
This formula focuses on enhancing sperm quality and quantity, complementing broader fertility strategies. Research on similar multi-antioxidant supplements has shown notable improvements in sperm concentration, motility, vitality, and morphology after three months of consistent use. Most users can expect to see results within three to six months. Here's a closer look at the ingredients in Sperm Worms gummies and how they contribute to male reproductive health.
Key Ingredients and Their Benefits
Each ingredient in Sperm Worms gummies has a specific role in promoting male fertility:
- Zinc: Vital for testosterone production and sperm development. Low zinc levels are often linked to reduced sperm count and poor quality. Studies show that zinc supplementation can increase sperm concentration by about 18.5 million sperm per milliliter and improve semen volume, motility, and overall sperm health after three months.
- Selenium: Protects sperm from oxidative stress during development, which is crucial for maintaining motility and overall health. Research has demonstrated that selenium paired with N-acetyl-cysteine significantly improves semen parameters over 30 weeks.
- Folate: Essential for DNA synthesis and proper cell division during sperm production. Folate deficiency is associated with lower sperm counts and poor morphology. Adequate folate levels support better concentration, vitality, and motility while reducing DNA damage risks.
- Vitamin D3: A critical nutrient for male fertility. A 2019 review of 18 studies found that higher Vitamin D levels were linked to improved sperm count and overall fertility.
- Vitamin E: Acts as a powerful antioxidant, protecting sperm cells from oxidative damage. Supplementation with Vitamin E has been shown to significantly improve fertilization rates after three months.
- L-Carnitine: Supports energy production in sperm cells, which is essential for motility. Studies indicate that supplementation with L-Carnitine and L-Acetyl Carnitine boosts sperm motility after six months.

When to See a Doctor
Getting a professional evaluation is key when dealing with fertility concerns. A doctor can help pinpoint underlying issues and guide you toward the right treatment plan.
Tests Doctors Use for Male Fertility
When visiting a fertility specialist, the process usually starts with a detailed review of your reproductive history. This includes looking at past medical conditions, surgeries, lifestyle habits, medications, sexual health, and any family history of infertility. A physical exam of your reproductive anatomy follows, which can uncover issues like varicoceles or blockages.
One of the most important tests is a semen analysis, which measures critical factors such as ejaculate volume, sperm concentration, movement (motility), and shape (morphology). To ensure accuracy, doctors typically ask for two samples collected about a month apart.
Blood tests to check hormone levels are another important step. These tests assess hormones like follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and prolactin. They are especially helpful if you’re experiencing symptoms like reduced libido, erectile dysfunction, or a low sperm count.
In cases of primary infertility and extremely low sperm counts (less than 5 million per milliliter), genetic testing may be recommended. This can include karyotype analysis and Y-chromosome microdeletion testing. If there’s an absence of the vas deferens or unexplained blockages, doctors might also perform CFTR mutation testing, as mutations in this gene account for up to 80% of congenital bilateral absence of the vas deferens cases.
Imaging tests provide a closer look at the reproductive system. Scrotal ultrasonography is often used to evaluate testicular size, detect masses, and identify varicoceles. For men with very low ejaculate volume, transrectal ultrasonography can help find blockages in the ejaculatory ducts. Interestingly, testicular ultrasonography has revealed abnormalities in 38% of infertile men, with varicoceles found in about 30% and testicular cancer in 0.5% of cases.
Other specialized tests might include antisperm antibody screening, sperm function tests, or semen cultures to check for infections when white blood cell counts are elevated. These tests can be crucial in identifying situations where immediate medical attention is necessary.
Warning Signs That Need Medical Care
Sometimes, symptoms can signal it’s time to seek medical advice, even before testing. A sudden loss of sex drive or ongoing issues like testicular pain or swelling shouldn’t be ignored.
Pain, swelling, or lumps in the testicles could point to conditions like testicular torsion, infections, hernias, or even testicular cancer, and these require immediate attention. Erectile dysfunction, which can interfere with conception, may also hint at underlying health problems. Irregular ejaculation, such as reduced volume or changes in appearance, is another red flag. For instance, yellow semen might indicate urine contamination, while green or pinkish semen could suggest a prostate issue.
A drop in sex drive may stem from hormonal imbalances, particularly low testosterone. Symptoms like fatigue, impotence, depression, or weight gain can also be tied to low testosterone levels.
Your medical history plays a big role too. If you’ve experienced testicular trauma, had hernia surgery, undergone chemotherapy or radiation, dealt with sexually transmitted infections, or have chronic conditions like diabetes, heart disease, or thyroid disorders, it’s a good idea to get evaluated sooner rather than later.
"It's not uncommon to hear patients during our initial consultation say, 'We haven't used any forms of contraception for at least a year, but we have only really been trying to conceive for about six months,'" explains Dr. Jason Bromer.
Male factors contribute to infertility in about half of all cases, with male-specific issues alone accounting for 20–30% of infertility in couples. The good news? Many male fertility problems can be effectively treated when caught early.
Proven Ways to Improve Fertility
Making specific adjustments to your daily habits can have a meaningful impact on fertility. While the full process of sperm production takes about 2.5 to 3 months, noticeable improvements in sperm quality can occur within 30 to 60 days with targeted changes.
Lifestyle Changes That Work
Weight management is a key factor in male fertility. Being just 20 pounds over your ideal weight increases the risk of infertility by 10%. Keeping a healthy BMI helps maintain hormonal balance and prevents excess heat that can harm sperm production.
Regular exercise can significantly improve sperm quality. Studies show that active men have up to 73% higher sperm concentration compared to those with sedentary lifestyles. Experts recommend at least 150 minutes of moderate exercise or 75 minutes of vigorous activity per week. However, overtraining can lower testosterone levels, so balance is essential.
Temperature control also plays a big role. Sperm production thrives when testicular temperature stays slightly below body temperature, ideally between 91°F and 95°F. Even a small increase in scrotal temperature - just 1 to 1.5°C - can reduce sperm production and lead to abnormalities. To keep things cool, avoid placing laptops on your lap, limit time in hot tubs or saunas, and opt for loose-fitting clothing.
A Mediterranean-style diet can boost sperm health significantly. Men following this diet are nearly three times more likely to have healthy sperm compared to those with other eating patterns. Focus on fruits, vegetables, nuts, seeds, whole grains, and lean proteins, while cutting back on processed foods, sugars, and trans fats.
Stress management and avoiding harmful substances are equally important. Chronic stress can lower testosterone levels and impact fertility, so activities like meditation, yoga, or regular physical activity can help. Smoking, recreational drugs, and excessive alcohol consumption also harm sperm quality. Drinking over 14 alcoholic beverages per week can reduce testosterone and sperm quality, and more than 300 mg of caffeine daily (around three cups) may damage sperm DNA.
"Smoking and pot are really bad for sperm, and a lot of people might smoke casually. Even a little bit of a reduction can make a huge difference", says Dr. Neel Shah.
Reducing chemical exposure is another way to protect fertility. Wash produce thoroughly, use glass containers for food storage, and avoid harsh cleaning agents and pesticides.
These lifestyle adjustments not only improve sperm quality but also enhance the effectiveness of supplements when used together.
Comparing Different Fertility Methods
Lifestyle changes create a strong foundation for fertility improvement, and when combined with targeted supplements, they can further optimize results.
| Approach | Timeline for Results | Cost | Effectiveness | Sustainability | Potential Risks |
|---|---|---|---|---|---|
| Lifestyle Changes | 2–3 months for full effect | Low to moderate (e.g., gym memberships, healthy food) | Active men see a 73% higher sperm concentration | High – becomes part of daily life | Minimal when properly implemented |
| Sperm Worms Gummies | 30–60 days for improvements | $39.96/month (discounts for multi-month plans) | Contains clinically-dosed ingredients like Zinc, Selenium, and L-Carnitine | High – easy to incorporate daily | Low risk when used as directed |
| Individual Supplements | 3–6 months | Variable | Mixed results – only 22% of ingredients have proven effects | Moderate – requires multiple pills daily | Risk of excessive intake ("reductive stress") |
Lifestyle changes stand out as an effective and holistic approach. For instance, adopting a Mediterranean diet can make men nearly three times more likely to have healthy sperm, while regular exercise improves sperm concentration by 73%. These changes not only benefit fertility but also enhance overall health.
Sperm Worms Gummies, developed by medical experts Joshua Kovoor, MD, PhD, and Brandon Stretton, MD, PhD, offer a convenient way to address specific nutritional needs. With clinically effective doses of Zinc, Selenium, L-Carnitine, and other key nutrients, this supplement targets sperm motility, shape, and count. Unlike many fertility products - where only 17% of ingredients are supported by evidence - Sperm Worms is backed by research.
On the other hand, individual supplements often fall short. Many contain ineffective doses or lack scientific support. A review of 17 popular male fertility supplements found an average efficacy score of just 1.66 out of 5.0, leaving users with little to show for their efforts.
The best results come from combining lifestyle changes with targeted supplementation. Supplements like Sperm Worms address specific nutritional needs and oxidative stress, but they work best alongside a healthy diet, regular exercise, stress management, and reduced chemical exposure. Together, these strategies provide the strongest chance of improving fertility while promoting overall well-being.
"A healthy body leads to healthy sperm production", explains Dr. Ali Dabaja, Urologist and Male Reproductive Specialist at Henry Ford Health.
Key Points About Male Fertility
Male fertility relies on a variety of interconnected factors, and understanding these can empower men to make informed choices about their reproductive health. Since sperm production takes about 12 weeks, any improvements from lifestyle changes or supplements require time and consistency.
Healthy sperm production depends on maintaining the right temperature. Testicles need to stay around 2°F cooler than the rest of the body. To achieve this, it’s best to avoid habits like placing laptops directly on your lap, spending too much time in hot tubs, or wearing tight-fitting underwear.
Diet plays a big role in sperm quality. A Mediterranean-style diet - packed with fruits, vegetables, nuts, seeds, whole grains, and lean proteins - provides essential nutrients and antioxidants. These antioxidants help fight oxidative stress, which is linked to 30%–80% of male infertility cases.
"A healthy body leads to healthy sperm production", says Dr. Ali Dabaja, Urologist and Male Reproductive Specialist at Henry Ford Health.
Steering clear of harmful substances is crucial for fertility. Smoking, heavy alcohol use, and recreational drugs can severely disrupt sperm production and lower testosterone levels. Reducing exposure to environmental toxins like pesticides, heavy metals, and BPA is also important. Simple steps, such as washing fruits and vegetables thoroughly and using glass containers for food storage, can help protect sperm quality.
Certain supplements can provide additional support. For example, Sperm Worms Gummies, developed by medical experts Joshua Kovoor, MD, PhD, and Brandon Stretton, MD, PhD, are formulated with ingredients like Zinc, Selenium, L-Carnitine, and Vitamin D3. These supplements are most effective when paired with a healthy lifestyle, addressing specific nutritional gaps that might not be covered by diet alone.
Chronic health issues, such as high blood pressure and diabetes, can negatively impact semen quality, sperm count, and motility. Stress is another factor that can take a toll, reducing sex drive and limiting sperm production. Incorporating stress-reduction techniques like meditation, yoga, or regular exercise can make a significant difference in maintaining fertility.
FAQs
What are some subtle signs of male fertility problems that might go unnoticed?
Some early signs of male fertility problems can often go unnoticed. These might show up as lowered sex drive, trouble maintaining an erection, or unusual ejaculation patterns. Physical symptoms like pain or swelling in the testicles, ongoing discomfort in the groin or lower abdomen, or even a reduction in testicle size could also signal underlying issues.
In addition, hormonal imbalances may present themselves through symptoms such as fatigue, muscle weakness, or noticeable shifts in body composition. If conceiving has become a challenge, it’s worth paying attention to these subtle signs and seeking advice from a healthcare provider for a thorough evaluation.
How do diet and exercise affect sperm health and male fertility?
Diet and exercise are key players when it comes to supporting sperm health and overall male fertility.
