Male Infertility: Causes, Symptoms, Diagnosis, Tests & Treatment

Quick Highlights

• Male infertility refers to a man’s inability to contribute to pregnancy due to low sperm count, poor motility, or structural issues.
• The causes of male infertility include hormonal imbalance, varicocele, infections or some lifestyle issues including smoking, stress etc.
• Symptoms of male infertility may not always be visible but can include difficulty in conceiving after a year of trying.
• The diagnosis of male infertility involves tests like semen analysis, hormonal analysis and imaging.
• Male fertility treatments include the use of medicines, hormone therapy, surgery and assisted reproductive procedures.

Male infertility is characterised as the inability to impregnate while having regular, unprotected sexual contact with a fertile female partner for more than 12 months. It can be concerning for couples who want to start a family but are facing issues with male fertility. To effectively treat male infertility, it is essential to comprehend its causes, symptoms, available treatments, and possibilities of recovery. An overview of male infertility and its factors is provided in the below article, along with details on its causes, signs, treatments, and prognosis.

Causes of Male Infertility:

Numerous physiological, genetic, environmental and lifestyle variables can contribute to male infertility. Effective diagnosis and treatment of fertility disorders depend on an understanding of the underlying root causes. Typically, male infertility can be a result of one of the following causes:

• Sperm-related disorders: Male infertility is significantly impacted by various disorders associated with sperm, such as low sperm count (oligospermia), poor sperm motility (asthenospermia), and aberrant sperm morphology (teratospermia).
• Hormonal Imbalances: It can be one of the significant causes of male infertility. Hormonal conditions like hypogonadism can have an impact on sperm count and general overall fertility health in males.
• Varicocele: This condition is generally normal in males during their reproductive years. During this disorder, the varicose scrotal vein gets enlarged in size, raising the temperature of the testicles, and also putting pressure on the sperm tube, affecting normal sperm production.
• Genetic Disabilities: Some genetic abnormalities in males, like Klinefelter syndrome and Y chromosomal microdeletions, can cause infertility.
• Infections: Infections like STIs such as chlamydia, gonorrhoea, or prostatitis can impact the normal function of healthy sperm production.
• Testicular Factors: There is a direct correlation between testicular abnormalities and fertility. Testicular cancer, testicular damage, or undescended testicles (cryptorchidism) are a few factors that can result in fertility disorders.
• Erectile dysfunction: Males having trouble getting or maintaining an erection may face issues having a successful sexual encounter in order to impregnate their female partner.
• Underlying Chronic Medical Issues: Male infertility can result from a variety of medical conditions. Sexually transmitted infections (STIs) and other chronic disorders like diabetes can have a detrimental effect on reproductive health. Fertility may also be impacted by illnesses like cystic fibrosis, which can cause the vas deferens (the tubes that deliver sperm) to be nonexistent or clogged.
• Lifestyle Factors: Male infertility can be impacted by smoking, binge drinking of alcohol, consumption of junk food, usage of drugs, obesity or irregular body weight, exposure to toxins in the environment, and high levels of stress.

Symptoms of Infertility in Male

Recognising the signs of male infertility is essential for tackling this issue because men’s reproductive health is necessary for successful conception. However, it is hard to see or notice any symptoms of infertility, there are a few signs that can indicate infertility in men. A few of them are:

Reduced Sexual Desire

Changes in sexual function are one of the main signs of male infertility. A persistent failure to obtain or maintain an erection, or erectile dysfunction (ED), may point to underlying fertility issues. Reduced libido or decreased sexual desire may also indicate hormonal abnormalities that impact sperm production.

Having Problems with Ejaculation

Ejaculatory issues may potentially be an indication of infertility. Retrograde ejaculation, which occurs when semen leaves the penis and exits through the bladder or premature ejaculation may be a sign of a problem with the reproductive system.

Lump, Pain, or Swelling

Another symptom to be looked for in men with infertility is physical discomfort. Infections, varicoceles (enlarged testicular veins) or other underlying problems that affect fertility can cause pain or swelling in the testicular region. Testicular cancer may be present if there are lumps or abnormalities and therapy may have an impact on fertility.

Diagnosis of Male Infertility

A thorough evaluation is necessary to determine the underlying causes of male infertility before beginning any treatment. Some diagnostic techniques include:

• Semen Analysis: A sample of semen is examined to determine the quantity, morphology, and motility of the sperm.
• Hormone Testing: Blood tests can measure hormone levels, including those of testosterone and follicle-stimulating hormone (FSH), which are essential for the creation of sperm.
• Scrotal Ultrasound: An ultrasound of the scrotum can identify blockages or anatomical irregularities in the reproductive canal.
• Genetic Testing: Through genetic testing, inherited diseases that impair fertility can be found.
• Testicular Biopsy: A biopsy of the testicles may be done in azoospermia instances to look for probable problems with sperm production.

Treatments for Male Infertility

Depending on the precise cause, treatment for male infertility may involve:

Common Risk Factors for Male Infertility

There are many potential risk factors and underlying causes for male infertility. Knowing these risk factors is essential for spotting possible problems and getting the right medical care when it’s required.

• Age: As people get older, their sperm quality and quantity may decrease. Men can have children later in life, but as they age, their fertility may decline.
• Smoking: Studies have shown that smoking reduces sperm quality, motility and quantity. It may also make sperm more likely to have genetic flaws.
• Alcohol & Drug Consumption: Drinking too much alcohol might affect the quantity and quality of sperm. Also,the use of some recreational drugs like cocaine or anabolic steroids can badly affect sperm motility and production.
• Obesity: Obesity can lead to a disruption of normal hormonal levels such as an increase in oestrogen. This can interfere with sperm quality and impact fertility.
• Sexually Transmitted Infections (STIs): Failure to seek treatment for some STIs such as Chlamydia, or Gonorrhoea can lead to blockages or scarring in the reproductive organs. This can lead to infertility.
• Varicocele: A varicocele is an enlargement of the veins in the scrotum. It may increase the temperature within the scrotal sac and harm the quality of sperm.
• Medical Conditions: Conditions like diabetes, hypertension and thyroid issues, can influence fertility by altering hormone levels or resulting in erectile dysfunction.
• Stress: Long-term stress can cause hormonal abnormalities that may have an impact on sperm count and sexual performance.
• Genetic Factors: Male infertility may result from certain genetic defects. In rare circumstances, genetic testing might be advised.
• Side Effects of Prescribed Medicines: Some drugs, such as those for high blood pressure, depression, or disorders of the prostate, may prevent conception.
• Testicular Trauma: Testicular trauma can result in scarring or other damage that impairs the generation of sperm.
• Unprotected Heat Exposure: Regular or lengthy exposure to hot environments, including those found in hot tubs or saunas, might momentarily lower sperm production.
• Treatments for Cancer: Chemotherapy and radiation therapy for cancer can harm sperm production, resulting in either temporary or permanent infertility.
• Occupational Exposures: Some professions expose workers to radiation, poisons, and chemicals that might impair sperm production. Examples include being exposed to radiation, heavy metals, or pesticides.

The fact that male infertility is frequently a complicated problem and that some risk factors may overlap is significant.
