I. Understanding Male Fertility and Sperm Quality

Male fertility is a complex physiological process intricately linked to the health and functionality of sperm. Subfertility or infertility affects a significant portion of the male population globally, and a substantial percentage of these cases are attributed to factors impacting sperm quality. Before delving into the role of dietary supplements (БАДы), it’s crucial to understand the key parameters that define healthy sperm.

A. Parameters of Sperm Quality:

Sperm quality is assessed based on several critical factors evaluated during a semen analysis. These parameters provide a comprehensive overview of a man’s reproductive potential.

1. Sperm Count (Concentration): This refers to the number of sperm cells present per milliliter of ejaculate. World Health Organization (WHO) guidelines establish a reference value of at least 15 million sperm per milliliter. Lower concentrations are classified as oligozoospermia, indicating a reduced sperm count, which can significantly hinder fertilization.

2. Motility (Progressive Motility): Motility describes the ability of sperm to move effectively. Progressive motility, in particular, refers to sperm moving forward in a straight line or large circles. The WHO recommends that at least 32% of sperm exhibit progressive motility for optimal fertility. Asthenozoospermia is the term for reduced sperm motility. Impaired motility compromises the sperm’s ability to navigate the female reproductive tract and reach the egg.

3. Morphology: Morphology refers to the shape and structure of sperm cells. Normal morphology is crucial for proper sperm function, including binding to and penetrating the egg. The WHO uses strict criteria (Kruger criteria) to assess morphology, with a reference value of at least 4% of sperm exhibiting normal forms. Teratozoospermia is the term for a high percentage of abnormally shaped sperm. Abnormal morphology can impair sperm’s ability to fertilize the egg.

4. Semen Volume: The volume of ejaculate contributes to sperm delivery. The WHO reference value is at least 1.5 milliliters. Low semen volume (hypospermia) can reduce the number of sperm deposited in the female reproductive tract.

5. Semen pH: The pH of semen is typically slightly alkaline, ranging from 7.2 to 8.0. An abnormal pH can indicate infection or other underlying issues.

6. Liquefaction Time: After ejaculation, semen initially coagulates and then liquefies within a specific timeframe. Delayed liquefaction can impair sperm motility. Typically, semen should liquefy within 20-30 minutes.

7. Vitality (Viability): Vitality refers to the percentage of live sperm in the sample. A high percentage of dead sperm (necrozoospermia) can indicate problems with sperm production or storage. At least 58% of sperm should be alive.

8. White Blood Cells (Leukocytes): A high concentration of white blood cells in semen (leukocytospermia) can indicate infection or inflammation in the reproductive tract, which can negatively impact sperm quality.

B. Factors Affecting Sperm Quality:

Numerous factors can influence sperm quality, both modifiable and non-modifiable. Identifying these factors is essential for developing strategies to improve male fertility.

1. Age: Male fertility generally declines with age, although the decline is typically more gradual than in women. Sperm volume, motility, and morphology can be negatively affected by aging.

2. Lifestyle Factors: Lifestyle choices play a significant role in sperm health.

   • Smoking: Smoking is strongly associated with reduced sperm count, motility, and morphology. Nicotine and other toxins in cigarette smoke can damage sperm DNA and impair sperm production.

   • Alcohol Consumption: Excessive alcohol consumption can negatively impact testosterone production and sperm quality.

   • Drug Use: Illicit drugs, such as marijuana, cocaine, and anabolic steroids, can severely impair sperm production and fertility.

   • Obesity: Obesity is linked to hormonal imbalances, including lower testosterone levels, and can negatively affect sperm quality.

   • Diet: A diet lacking in essential nutrients can compromise sperm health. Deficiencies in vitamins, minerals, and antioxidants can impair sperm production and function.

   • Stress: Chronic stress can disrupt hormonal balance and negatively impact sperm quality.

   • Lack of Sleep: Insufficient sleep can disrupt hormone production and negatively affect sperm health.

3. Medical Conditions: Certain medical conditions can impair sperm production or function.

   • Varicocele: A varicocele is an enlargement of the veins within the scrotum, which can increase scrotal temperature and impair sperm production.

   • Infections: Infections of the reproductive tract, such as epididymitis or prostatitis, can damage sperm and reduce fertility. Sexually transmitted infections (STIs) like Chlamydia and gonorrhea can also cause infertility.

   • Hormonal Imbalances: Imbalances in hormones, such as testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH), can disrupt sperm production.

   • Genetic Factors: Certain genetic conditions, such as Klinefelter syndrome or Y chromosome microdeletions, can cause infertility.

   • Autoimmune Disorders: In some cases, the body’s immune system can attack sperm cells, leading to infertility.

   • Cystic Fibrosis: This genetic disorder can cause the absence of the vas deferens, the tube that carries sperm from the testes.

   • Undescended Testicles (Cryptorchidism): If one or both testicles fail to descend into the scrotum during development, it can impair sperm production.

4. Environmental Factors: Exposure to certain environmental toxins can negatively affect sperm quality.

   • Pesticides: Exposure to pesticides has been linked to reduced sperm count and motility.

   • Heavy Metals: Heavy metals, such as lead and mercury, can damage sperm and impair fertility.

   • Radiation: Exposure to radiation can damage sperm DNA and reduce fertility.

   • Heat: Prolonged exposure to heat, such as from hot tubs or saunas, can impair sperm production.

5. Medications: Certain medications can negatively affect sperm quality.

   • Anabolic Steroids: These synthetic hormones can suppress sperm production.

   • Chemotherapy Drugs: Chemotherapy can damage sperm-producing cells.

   • Certain Antidepressants: Some antidepressants can affect sperm motility.

   • Alpha-Blockers: These medications, used to treat prostate problems, can cause retrograde ejaculation, where semen enters the bladder instead of being ejaculated.

II. The Role of Dietary Supplements (БАДы) in Enhancing Sperm Quality
