Overview
Infertility is a disease of the male or female reproductive system, defined by the failure to achieve a pregnancy after 12 months or more of regular unprotected sexual intercourse. It can cause significant distress, stigma, and financial hardship, affecting people’s mental and psychosocial well-being.
What is Male Infertility
Male infertility occurs when a man has a reduced ability to father a child. Various factors can lead to male infertility.
Biological factors include sperm-related issues such as malformed sperm, low sperm count (oligospermia), and absence of sperm in semen (azoospermia). Genetic disorders like Klinefelter syndrome and myotonic dystrophy can also contribute.
Another factor to consider is blockage in the sperm delivery system. This could be due to infections, surgeries, or congenital issues that obstruct the tubes carrying sperm.
Medical conditions such as diabetes, certain autoimmune diseases, and cystic fibrosis may affect fertility. Infections like epididymitis, orchitis, and sexually transmitted infections (STIs) including gonorrhea or HIV, can play a role.
Additionally, swollen veins in the testicles (varicoceles) and treatments for cancer—chemotherapy, radiation therapy, or surgical removal of the testicles (orchiectomy)—can be contributing factors.
Testicular trauma and hormonal disorders involving the hypothalamus or pituitary glands also impact fertility.
Environmental factors include exposure to radiation, toxins such as lead, calcium, pesticides or mercury, and lifestyle choices like tobacco, marijuana, or alcohol use.
Certain medications, including flutamide, spironolactone, and bicalutamide, can affect fertility.
Physical factors also matter. Spending time in environments that elevate the temperature of the testicles, such as saunas or hot tubs, using a wheelchair, long distance truck driving as a profession can increase infertility risk.
Lifestyle choices also play a role. Smoking, excessive alcohol consumption, and drug use can negatively impact sperm health. Additionally, obesity and a sedentary lifestyle can contribute to fertility issues.
Addressing male infertility often involves medical evaluation and lifestyle changes. Diagnostic tests include semen analysis, hormone testing, and imaging studies. Treatment options may range from medication and surgery to assisted reproductive technologies like IVF.
What Causes Male Infertility?
Male infertility can result from a variety of factors, many of which affect the production or function of sperm. Ensuring you understand these causes can help in identifying potential treatment options.
Hormonal Imbalances
Hormones play a crucial role in sperm production. Imbalances in hormones such as testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) can disrupt the development and release of healthy sperm.
Genetic Factors
Certain genetic conditions, such as Klinefelter syndrome or Y chromosome microdeletions, can impair testicular function. These genetic issues often result in low sperm production or abnormal sperm.
Anatomical Issues
Structural problems within the male reproductive system can lead to infertility. Examples include blockages within the vas deferens or epididymis, varicocele (enlarged veins within the scrotum), and undescended testicles.
Lifestyle and Environmental Factors
Your lifestyle and environment can significantly impact fertility. Factors such as smoking, excessive alcohol consumption, drug use, exposure to toxins, and obesity can negatively affect sperm quality and quantity.
Medical Conditions
Certain medical conditions are known to affect male fertility. These include infections such as epididymitis or orchitis, chronic illnesses like diabetes, and surgeries that impact the reproductive organs.
Medications
Some medications can interfere with sperm production and function. Drugs used to treat cancer, certain antibiotics, and medications for hypertension may have adverse effects on fertility.
Age
Age can also be a contributing factor. Men over the age of 50 may experience a decline in sperm quality, which can affect their ability to father a child.
Sexual Health Issues
Issues such as erectile dysfunction or premature ejaculation can hinder the ability to conceive.

Male Infertility Symptoms
- Difficulty with Ejaculation
You may notice trouble with ejaculating, including reduced volume of ejaculated fluid. - Pain and Swelling
Discomfort or swelling in the testicle area could indicate underlying problems such as testicular torsion or varicocoele. - Erectile Dysfunction
Difficulty in getting and maintaining an erection can point to fertility issues. - Decreased Facial or Body Hair
A decrease in hair growth might signal hormonal imbalances affecting fertility.
Affected Populations in Male Infertility
Age Groups
- Young Adults (20-35 years): This group might experience infertility related to harmful lifestyle factors such as smoking, alcohol use, or recreational drug use.
- Middle-Aged Men (36-50 years): Health issues like diabetes and obesity often start affecting fertility in this age range.
- Older Men (51 and above): Age can lead to decreased sperm quality and other age-related factors.
- Jobs Involving Heat Exposure: Occupations like welders or bakers, which expose individuals to high temperatures, long-distance truck driving, etc.
- Chemical Exposure: Workers in industries that involve handling pesticides or heavy metals.
Evaluating Male Infertility
- Semen Analysis: This test measures the quantity and quality of sperm. It looks at sperm count, motility (movement), and morphology (shape). You may need to provide a semen sample at a clinic or laboratory.
- Hormone Testing: Blood tests can check the levels of hormones that play a role in sperm production, such as testosterone and follicle-stimulating hormone (FSH).
- Scrotal Ultrasound: This imaging test checks the testicles and adjacent structures for abnormalities.
- Genetic Tests: These can identify genetic causes of infertility by analyzing your DNA.
- Anti-Sperm Antibodies Test: This detects antibodies that may attack sperm, hindering their ability to function properly.
- Post-Ejaculation Urinalysis: This checks for sperm in the urine, which may indicate retrograde ejaculation, a condition where sperm enters the bladder instead of being expelled.
Your healthcare provider may recommend additional tests based on initial results, so following their guidance is crucial.
Managing and Treating Male Infertility
Medical Therapy
- Hormone Treatments: Hormonal imbalances can impact sperm production. Medication to balance hormones such as FSH, LH, and testosterone can improve fertility.
- Antibiotics: Infections in the reproductive tract can contribute to infertility. Antibiotics can treat these infections but may not restore fertility if significant damage has occurred.
Surgical Interventions
- Varicocele Repair: Varicocele, which is the enlargement of veins within the scrotum, is a common cause of male infertility. Surgical procedures can remove or repair these veins to enhance sperm quality.
- Vasovasostomy and Vasoepididymostomy: These surgeries can reverse vasectomies or treat blockages in the vas deferens or epididymis, restoring sperm flow.
Assisted Reproductive Technologies (ART)
- Intrauterine Insemination (IUI): This technique involves placing concentrated sperm directly into the uterus during ovulation to facilitate fertilization.
- Intracytoplasmic Sperm Injection (ICSI): During ICSI, a single sperm is injected directly into an egg, which is then transferred to the uterus. This method is often used in conjunction with IVF.
- In Vitro Fertilization (IVF): Sperm and eggs are combined outside the body in a lab. Embryos formed are then implanted into the uterus.
Lifestyle Modifications
- Diet and Exercise: A balanced diet rich in antioxidants and regular physical activity can improve sperm quality and overall reproductive health.
- Avoiding Toxins: Reducing exposure to chemicals, smoking, and excessive alcohol can boost fertility.
Psychological Support
- Counselling and Support Groups: Infertility can be emotionally taxing. Accessing psychological support can help you and your partner cope with stress and emotional challenges.
