In Advanced Reproductive Technologies (ART), semen analysis plays a crucial role in evaluating infertility cases. Male factor infertility accounts for nearly 40% of all infertility cases and is often related to abnormalities in sperm production, quantity, or quality.

Although there have been ongoing discussions regarding the standardization of semen analysis, most practitioners worldwide follow the guidelines and recommendations established by the World Health Organization (WHO). These guidelines provide standardized reference values for assessing semen quality and fertility potential.

Optimal Semen Characteristics

In human male reproduction, sperm development takes approximately 74–100 days. The process involves:

• Spermatogenesis – Development of stem cells into mature spermatozoa

• Spermiogenesis – Final maturation of spermatozoa into functional sperm cells

This complex biological process results in the release of millions of sperm during ejaculation.

According to WHO guidelines, the recommended abstinence period before semen analysis is 2 to 7 days.

Standard Parameters for Semen Analysis

• Volume: 1.4–1.7 mL

• Liquefaction time: Less than 60 minutes at room temperature

• Appearance: Grey and opalescent

• Consistency: Discrete droplet

• Leukocytes: Less than 1 million/mL

• Sperm concentration: 12–16 million/mL

• Total sperm count: 33–46 million

• Total motility: 38–42%

• pH: 7.2

• Morphology: 3–4% normal forms

For accurate evaluation, at least two semen samples are recommended in men with infertility concerns.

Factors Causing Suboptimal Semen Characteristics

1. Temperature and Spermatogenesis

Spermatogenesis occurs at a temperature slightly lower than body temperature. Disruption in thermoregulation can impair sperm production. Heat exposure may lead to:

• Germ cell apoptosis

• DNA damage

• Autophagy

• Reduced sperm quality

2. Smoking

Cigarette smoke contains over 7,000 harmful chemicals, including carcinogens and volatile organic compounds. Smoking can:

• Damage sperm DNA

• Cause mutations and fragmentation

• Reduce sperm count

• Impair motility and morphology

3. Alcohol Consumption

Excessive alcohol intake disrupts the Hypothalamus-Pituitary-Gonadal (HPG) axis, affecting hormone production including:

• GnRH

• FSH

• LH

• Testosterone

This hormonal imbalance impairs Leydig and Sertoli cell function, leading to:

• Reduced sperm production

• Poor morphology

• Impaired maturation

4. Recreational Drugs

Drugs such as marijuana, anabolic androgenic steroids (AAS), narcotics, and cocaine negatively impact male fertility.

• Marijuana disrupts the Endogenous Cannabinoid System (ECS), impairing spermatogenesis

• Cocaine induces apoptosis and damages testicular structure

• AAS suppress the HPG axis, potentially causing testicular atrophy and infertility

Long-term use may result in reversible or irreversible fertility suppression.

5. Obesity

Excess body fat affects hormonal balance:

• Converts testosterone to estrogen

• Reduces gonadotropin release

• Lowers testosterone levels

Obesity also increases scrotal temperature and oxidative stress, leading to:

• Impaired spermatogenesis

• Reduced motility

• DNA damage

6. Psychological Stress

Although stress lacks measurable parameters, it significantly impacts reproductive function. Chronic stress may:

• Alter hormone levels

• Reduce testosterone

• Lower semen volume

• Decrease motility

7. Advanced Paternal Age (Above 35 Years)

Age-related decline in male reproductive health may cause:

• Reduced semen volume

• Lower sperm count

• Decreased motility

• Increased DNA fragmentation

Structural and cellular changes in the testes contribute to reduced fertility potential.

8. Diet and Caffeine

Unhealthy dietary habits such as excessive intake of:

• Processed meats

• High-fat foods

• Sugary beverages

• Excess caffeine

• Alcohol

are associated with poorer semen quality and reduced reproductive capacity.

9. Lifestyle and Occupational Factors

Prolonged sitting, excessive exposure to radiant heat, and sedentary work lifestyles increase scrotal temperature, leading to:

• Spermatogenic arrest

• Germ cell apoptosis

• DNA damage
