Male Infertility: Causes, Spermiogram, and the Path to Fatherhood

Introduction: Male Infertility – An Important Reproductive Health Issue

Infertility is a serious issue in modern society, affecting many couples. The male factor contributes to approximately 50% of all infertility cases [3]. For a long time, research on male infertility focused primarily on the testes; however, accumulating evidence points to the critical role of other organs and systems, such as the prostate gland and a man's overall health status [3]. Understanding the causes and ensuring timely diagnosis, particularly through a spermiogram, play a key role in finding effective solutions.

Prostatitis: The Hidden Enemy of Male Fertility

The prostate gland is the largest male accessory sex gland and plays a vital role in semen quality [3, 6]. Prostatic fluid, which constitutes a significant portion of semen, substantially affects sperm function and overall male fertility [3].

Inflammation of the prostate gland, or prostatitis, is one of the most common prostate diseases, especially with advancing age [3]. It can be caused by infections (e.g., Escherichia coli, Chlamydia trachomatis), autoimmune reactions, or other factors [2]. Prostate inflammation can negatively impact male fertility through two main pathways:

• Direct impact on sperm quality: The inflammatory process can directly damage sperm, impairing their motility, morphology, and viability [2].
• Indirect effect via impaired prostate function: The prostate secretes a number of factors, such as zinc and citrate, which are critical for sperm activation and fertilizing capacity [6]. Inflammation can disrupt the secretion of these substances, thereby indirectly impairing fertility [2, 6].

Thus, prostatitis can severely undermine reproductive health, and its timely detection and treatment are of great importance [3].

Obesity and Overweight: Impact on Sperm Quality

Overweight and obesity are not only general health concerns but also significant risk factors for male fertility. An increasing number of studies show that excess body weight can negatively affect sperm quality [1].

The mechanisms by which obesity affects male reproductive function include:

• Hormonal imbalance: Obesity is often accompanied by changes in hormone levels, including decreased testosterone levels, which can disrupt spermatogenesis [1].
• Oxidative stress: The expansion of adipose tissue promotes increased oxidative stress in the body, which can damage sperm and their DNA [1].
• Metabolic disorders: Obesity is associated with various metabolic disorders that can also negatively affect sperm production and quality [1].

A study involving 112 men seeking fertility evaluation demonstrated a clear link between body mass index (BMI) and sperm abnormalities. Overweight and obese men were more likely to have quantitative and qualitative abnormalities in their spermiogram compared to men with a normal BMI [1].

Hormonal Background: The Role of Testosterone

Testosterone is the primary male androgen regulating reproduction, metabolism, and erythropoiesis [5]. Its levels naturally decline with age, which can affect general health and fertility [5, 7]. Low testosterone levels (hypogonadism) may be associated with various conditions, including hypertension [5]. Although the direct impact of low testosterone on fertility is not always unequivocal, its imbalance can disrupt the delicate processes of spermatogenesis and affect libido and erectile function, indirectly hindering conception.

Spermiogram: The Key to Diagnosing Male Infertility

A spermiogram (semen analysis) is the primary and most informative method for diagnosing male infertility. It allows for the evaluation of key ejaculate parameters that provide insight into a man's reproductive function. According to World Health Organization (WHO) criteria, the spermiogram evaluates the following parameters:

• Ejaculate volume: The amount of semen produced.
• Sperm concentration: The number of sperm in one milliliter of ejaculate.
• Sperm motility: The percentage of actively moving sperm, their speed, and movement characteristics.
• Sperm morphology: The percentage of sperm with normal shape.
• Viability: The percentage of live sperm.
• Presence of leukocytes: May indicate an inflammatory process.
• pH and viscosity: Physicochemical properties of the ejaculate.

Abnormalities in any of these parameters can indicate fertility issues. For example, in the study on the link between obesity and infertility, the spermiogram was specifically used to evaluate and compare qualitative and quantitative sperm abnormalities across different groups of men [1]. Thorough analysis of spermiogram results enables the physician to determine potential causes of infertility and develop an individualized treatment plan.

Conclusion: A Comprehensive Approach to Male Reproductive Health

Male infertility is a multifactorial issue requiring a comprehensive approach to diagnosis and treatment. From inflammatory diseases of the prostate gland to systemic problems such as obesity and hormonal disorders, every aspect of a man's health can affect his ability to conceive. The spermiogram remains the cornerstone in assessing male fertility, providing valuable information for subsequent steps. Timely consultation with a specialist and adequate therapy significantly increase the chances of successfully overcoming infertility.
