Male infertility affects nearly 50% of couples facing fertility challenges, yet its causes often go beyond common lifestyle choices like diet, exercise, and smoking. At the Andrology Center in Coimbatore, we emphasize the importance of exploring lesser-known biological factors that significantly impact male fertility. As the only authorised lab in India for the SCSA® test (Sperm Chromatin Structure Assay) for DNA fragmentation, we provide cutting-edge solutions to uncover and address these hidden causes.
Here’s a closer look at some unexplored biological reasons behind male infertility and how they can be managed effectively.
1. Genetic Abnormalities: The Hidden Culprits
Certain genetic conditions disrupt the normal production and quality of sperm:
Klinefelter Syndrome
- What it is: A chromosomal disorder where males have an extra X chromosome (47, XXY instead of the typical 46, XY).
- Effects: Causes small testicles, low testosterone levels, reduced sperm production, and often results in non-obstructive azoospermia (no sperm in the ejaculate due to production issues).
Y-Chromosome Microdeletions
- What it is: Missing small portions of genetic material on the Y chromosome, which is crucial for sperm production.
- Effects: Specific deletions (e.g., AZF regions: AZFa, AZFb, AZFc) can result in severely reduced sperm production or absence of sperm.
👉 Why it matters:
- Genetic Testing: Karyotyping and Y-chromosome microdeletion tests can identify these abnormalities.
- Treatment Options: Assisted reproductive technologies (ART), such as IVF with Intracytoplasmic Sperm Injection (ICSI), can be tailored to address genetic infertility. Genetic counseling helps couples understand their reproductive options.
2. Hormonal Imbalances: Not Just About Testosterone
Low Testosterone (Hypogonadism)
- What it is: A condition where the body produces insufficient testosterone, the hormone essential for sperm production and male reproductive health.
- Causes: Can result from aging, injury to the testicles, pituitary disorders, or systemic illnesses.
High Prolactin Levels (Hyperprolactinaemia)
- What it is: Excessive levels of the hormone prolactin, which inhibits gonadotropin-releasing hormone (GnRH), leading to reduced testosterone and sperm production.
- Causes: Often caused by pituitary tumors or certain medications.
👉 What you can do:
- Diagnosis: Blood tests for hormone levels (FSH, LH, testosterone, and prolactin).
- Treatment: Hormone replacement therapy, medications to lower prolactin levels, or lifestyle adjustments such as stress reduction and weight management.
3. Varicocele: A Common but Underrated Factor
What it is:
- A varicocele is an enlargement of veins in the scrotum, similar to varicose veins in the legs.
- It causes pooling of blood, which increases testicular temperature and reduces oxygen supply, negatively impacting sperm production and quality.
Symptoms: Often asymptomatic, but some men experience scrotal pain or a visible lump.
Treatment: Surgical Correction (Varicocelectomy): A procedure to tie off the affected veins, improving blood flow and testicular function. This often leads to improved sperm quality and fertility outcomes.
👉 Early detection through a physical examination or scrotal ultrasound is essential.
4. DNA Fragmentation: The Unseen Sperm Quality Issue
What it is:
- Damage to the DNA within sperm cells, referred to as DNA fragmentation, can result from oxidative stress, infections, toxins, or aging.
- This affects the sperm’s ability to fertilize the egg and can lead to miscarriages or failed IVF/ICSI cycles.
Why it matters: A standard semen analysis may not detect DNA fragmentation. Advanced tests like the SCSA® (Sperm Chromatin Structure Assay) provide precise insights.
Treatment:
- Addressing underlying causes (e.g., oxidative stress, infections).
- Antioxidant therapy and lifestyle modifications often improve outcomes.
5. Autoimmune Disorders: The Body’s Unexpected Response
- What it is: The immune system mistakenly identifies sperm as foreign invaders, producing anti-sperm antibodies that impair motility, function, or fertilization capability.
- Testing: MAR (Mixed Antiglobulin Reaction) Test: Used to detect anti-sperm antibodies.
Treatment:
- Immunosuppressive Therapy: Medications to reduce the immune response.
- ART Solutions: Techniques like IVF can bypass some of the barriers caused by anti-sperm antibodies.
6. Environmental Toxins: A Silent Contributor
- What they are: Harmful substances such as heavy metals (lead, mercury), pesticides, industrial chemicals, and air pollutants can harm sperm by inducing oxidative stress.
- Impact: Oxidative stress damages sperm DNA, lowers motility, and reduces overall sperm count.
Actionable Steps:
- Minimize exposure by wearing protective gear in hazardous environments.
- Detoxify through antioxidant-rich diets (e.g., fruits, vegetables, nuts) and supplements like Vitamin C, Vitamin E, and Coenzyme Q10.
7. Infections and Inflammations: Silent Saboteurs
- What they are: Epididymitis (inflammation of the epididymis), orchitis (inflammation of the testes), or sexually transmitted infections (STIs) can cause scarring or blockages in the reproductive tract.
- Impact: Leads to reduced sperm production or impaired sperm transport.
Prevention and Treatment:
- Practice safe sex and maintain good hygiene.
- Early medical intervention with antibiotics or anti-inflammatory medications can prevent long-term damage.
8. Oxidative Stress: The Invisible Threat
- What it is: An imbalance between free radicals (harmful molecules) and antioxidants. Free radicals attack sperm cells, affecting their count, motility, and DNA integrity.
- Causes: Smoking, alcohol, poor diet, pollution, and chronic stress contribute to oxidative stress.
Solutions:
- Antioxidant Therapy: Supplements like Zinc, Selenium, and Lycopene.
- Dietary Changes: Incorporate antioxidant-rich foods like berries, green leafy vegetables, and nuts.
- Lifestyle Adjustments: Reduce stress, quit smoking, and avoid alcohol.
