Asthenospermia, sometimes called asthenozoospermia, is a condition where the sperm have reduced motility or movement. This can affect a man’s fertility and is often discovered during routine semen analysis when couples face difficulties with conception.
Asthenospermia is a medical term referring to decreased sperm motility. In simple terms, the sperm are not moving as well as they should, which can reduce their ability to reach and fertilize an egg. Although many men with asthenospermia may not notice any symptoms, the condition is often identified during fertility evaluations. Low motility can result from various factors, including lifestyle influences, medical conditions, or environmental exposures.
Key points:
- Low Motility: Sperm movement is essential for natural conception.
- Fertility Impact: Reduced motility can lead to lower chances of achieving pregnancy.
- Diagnosis: Typically discovered during semen analysis as part of fertility assessments.
Pathophysiology of Asthenospermia
Understanding the pathophysiology means looking at how the condition develops and affects the body. For asthenospermia, several factors play a role:
Structure
The male reproductive system includes the testes, epididymis, vas deferens, seminal vesicles, prostate gland, and urethra. Sperm are produced in the testes and then mature as they travel through the epididymis. In asthenospermia, there may be structural changes in the sperm tail (flagellum) which is responsible for movement. Abnormalities in the axoneme—the central structure of the tail that contains microtubules—can lead to decreased motility.
Blood Supply
Good blood flow is critical for providing oxygen and nutrients to the reproductive organs. The testes receive blood from the testicular arteries, and any compromise in the vascular system may affect sperm production and quality. Conditions like varicocele (enlarged veins in the scrotum) can disrupt blood flow, leading to increased temperature and oxidative stress, which in turn reduces sperm motility.
Nerve Supply
The reproductive organs receive nerve signals that regulate their functions. While the nerve supply is not directly linked to the movement of sperm, proper nerve function helps maintain healthy testicular and accessory gland functions. Any nerve damage or dysfunction could indirectly influence the hormonal environment needed for optimal sperm production.
Functions
The main function of sperm motility is to ensure that sperm can swim through the female reproductive tract to reach the egg. Healthy sperm have an energy source provided by mitochondria, located in the midpiece of the sperm. In asthenospermia, mitochondrial dysfunction or damage can reduce the energy available for movement, leading to lower motility and ultimately affecting fertility.
Types of Asthenospermia
Asthenospermia can be categorized based on its severity and underlying causes. The two broad types include:
Primary (Idiopathic) Asthenospermia:
- Occurs without a clearly identifiable cause.
- May be linked to genetic factors or subtle cellular defects.
- Diagnosis is made when routine tests fail to reveal an obvious reason for low motility.
Secondary Asthenospermia:
- Caused by an identifiable factor or condition.
- Includes lifestyle factors (smoking, alcohol), infections, exposure to toxins, varicocele, and other medical conditions.
- Treatment often involves addressing the underlying cause.
Within these categories, severity can vary from mild to severe based on the percentage of motile sperm.
Causes of Asthenospermia
There are many factors that can lead to reduced sperm motility. Here are 20 possible causes:
- Genetic Defects: Abnormalities in genes affecting sperm structure.
- Varicocele: Enlarged veins in the scrotum causing increased temperature.
- Infections: Bacterial or viral infections affecting the reproductive tract.
- Oxidative Stress: Imbalance between free radicals and antioxidants.
- Hormonal Imbalances: Low testosterone or high estrogen levels.
- Lifestyle Factors: Smoking, alcohol consumption, and drug abuse.

- Heat Exposure: Frequent exposure to high temperatures (e.g., hot tubs, saunas).
- Radiation Exposure: Radiation from medical treatments or environmental sources.
- Medications: Certain drugs can adversely affect sperm motility.
- Dietary Deficiencies: Lack of essential vitamins and minerals (e.g., zinc, selenium).
- Stress: Chronic psychological stress can affect hormone levels.
- Sedentary Lifestyle: Lack of physical activity can reduce overall health.
- Immune Disorders: Autoimmune conditions that attack sperm.
