Male Infertility Blood Test

What is Infertility in Men?

Male infertility is the inability to conceive after one year of regular unprotected intercourse due to male reproductive factors. It is caused by low sperm count, poor sperm motility, abnormal sperm morphology, hormonal imbalances, or nutritional deficiencies like selenium. The Selenium blood test is the most important test for identifying nutritional deficiencies that impact sperm production and male fertility.

What causes male infertility?

Male infertility is caused by low sperm count, poor sperm motility, abnormal sperm shape, hormonal imbalances affecting testosterone or follicle-stimulating hormone (FSH), varicoceles (enlarged veins in the scrotum), infections, genetic disorders, and nutritional deficiencies like low selenium or zinc. Environmental factors including smoking, excessive alcohol consumption, obesity, and exposure to toxins can also damage sperm production. Medical conditions such as diabetes, thyroid disorders, and certain medications can impair male reproductive function.

What is the best test for male infertility?

The Selenium blood test is the most important nutritional test for male infertility because it detects selenium deficiency, which directly impacts sperm production, motility, and overall quality. Selenium is essential for the formation of healthy sperm and protects sperm cells from oxidative damage. While semen analysis remains the primary diagnostic test for evaluating sperm count, motility, and morphology, checking selenium levels helps identify a correctable nutritional cause of poor sperm quality. Comprehensive fertility evaluation may also include hormone testing for testosterone, FSH, and luteinizing hormone (LH) to assess reproductive hormone balance.

When should I get tested for male infertility?

You should get tested if you and your partner have been trying to conceive for 12 months or longer without success. Men over 40 or those with risk factors like previous testicular injury, childhood mumps infection, varicoceles, chronic health conditions, or family history of fertility problems should consider testing sooner. If you notice symptoms like erectile dysfunction, reduced sexual desire, testicular pain or swelling, or difficulty with ejaculation, get tested promptly as these may indicate underlying fertility issues.

What are the symptoms of male infertility?
Male infertility often has no obvious symptoms beyond the inability to conceive. Some men may experience low sex drive, erectile dysfunction, difficulty maintaining an erection, reduced facial or body hair suggesting hormonal problems, pain or swelling in the testicles, or small firm testicles. You might notice problems with ejaculation, including reduced semen volume or difficulty ejaculating. Recurrent respiratory infections can indicate genetic conditions like cystic fibrosis that also affect fertility.
Who is at risk for male infertility?
Men at higher risk include those over 40 years old, smokers, heavy alcohol users, men who are overweight or obese, and those exposed to environmental toxins like pesticides or heavy metals. Having a history of undescended testicles, testicular trauma or surgery, varicoceles, sexually transmitted infections, or mumps after puberty increases risk. Men with chronic conditions like diabetes, thyroid disorders, or autoimmune diseases face higher infertility risk, as do those taking certain medications including steroids, chemotherapy drugs, or some blood pressure medications.
What happens if male infertility is left untreated?
Untreated male infertility leads to continued inability to conceive naturally, causing emotional stress, relationship strain, and missed opportunities for parenthood. Some underlying causes like hormonal imbalances, varicoceles, or nutritional deficiencies can worsen over time, further reducing fertility potential. Certain conditions causing infertility, such as testicular tumors or pituitary disorders, may have serious health consequences beyond fertility if not diagnosed and treated. Early testing and treatment provide the best chance for natural conception or successful assisted reproductive treatments.
Can male infertility be diagnosed with a blood test?
Blood tests cannot diagnose male infertility directly, but they play an essential role in identifying underlying causes. Semen analysis is the primary diagnostic test for male infertility, evaluating sperm count, motility, and morphology. Blood tests help detect hormonal imbalances by measuring testosterone, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin levels. The Selenium blood test identifies nutritional deficiencies affecting sperm production, while other blood work can reveal thyroid problems, diabetes, or genetic conditions contributing to fertility issues.
How is male infertility treated?
Treatment depends on the underlying cause identified through testing. Hormonal imbalances are treated with medications to restore normal hormone levels and stimulate sperm production. Varicoceles can be surgically corrected to improve sperm quality. Nutritional deficiencies like low selenium are addressed through dietary changes and supplementation with selenium-rich foods or supplements. Infections are treated with antibiotics, while lifestyle modifications including weight loss, quitting smoking, reducing alcohol, and avoiding environmental toxins improve fertility. Assisted reproductive technologies like intrauterine insemination (IUI) or in vitro fertilization (IVF) help couples conceive when other treatments are unsuccessful.
How can I prevent male infertility?
Maintain a healthy weight through balanced diet and regular exercise, as obesity negatively impacts testosterone levels and sperm production. Avoid smoking, limit alcohol consumption, and stay away from recreational drugs. Protect your testicles from injury during sports and avoid prolonged exposure to heat from hot tubs, saunas, or tight clothing. Minimize exposure to environmental toxins, pesticides, and heavy metals in your work or home environment. Eat a nutrient-rich diet including selenium from Brazil nuts, fish, and eggs, plus zinc from meat, shellfish, and legumes to support optimal sperm health.
What natural remedies help with male infertility?
Increase selenium intake through Brazil nuts (just 2-3 daily provide adequate selenium), fatty fish like salmon and tuna, eggs, and whole grains to support sperm production and quality. Consume zinc-rich foods including oysters, beef, pumpkin seeds, and lentils to boost testosterone and sperm count. Antioxidant-rich foods like berries, leafy greens, and tomatoes protect sperm from oxidative damage. Regular moderate exercise improves testosterone levels and overall fertility, but avoid excessive intense training which can have the opposite effect. Stress reduction through meditation, yoga, or counseling helps balance reproductive hormones and improves fertility outcomes.

What this means

Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
