Varicocele and Sperm Quality: What is the Extent of the Effect?
Varicocele is a condition in which the veins within the scrotum (the sac that holds the testicles) become abnormally enlarged, similar to varicose veins in the legs. It is often found in the left side of the scrotum more than the right and is one cause of male infertility.
🍎 Causes of Varicocele
Malfunction of Valves in the Scrotal Veins: Defective valves in the veins within the scrotum allow blood to flow backward, causing blood to pool in the veins. This leads to vein dilation and the formation of a varicocele.
High Pressure in the Left Renal Vein: The left testicular vein drains into the left renal vein. If the pressure in the left renal vein is high, or if it is compressed by adjacent organs, blood flow back will be slow, leading to pooling in the scrotal veins.
Anatomical Structure: The anatomical structure predisposes the left testicular vein to a higher chance of developing a varicocele than the right.
Increased Abdominal Pressure: Conditions that increase intra-abdominal pressure, such as regularly lifting heavy objects, exercises that increase abdominal pressure, or certain diseases that cause abnormal blood circulation.
Genetics: A hereditary predisposition that makes the veins prone to dilation.
🩺 Symptoms of Varicocele
Most Cases are Asymptomatic: Often detected incidentally during a physical examination.
Pain or Dull Ache: A dull ache or heavy sensation in the scrotum, especially when standing or exerting oneself for long periods.
Scrotal Asymmetry: One side of the scrotum may appear lower or be a different size.
Soft Lump: A soft mass that can be felt in the scrotum.
💥 Varicocele and its Impact on Fertility
Abnormal Sperm Production:
Low Sperm Count, Motility, or Morphology: Reduced number of sperm, slower movement, or abnormally shaped sperm.
Elevated Testicular Temperature: The increased temperature in the testicular area negatively affects sperm quality.
Lower Testosterone Levels: In some cases, it can lead to decreased male sex hormone (Testosterone) levels.
🩹 Initial Self-Care for Varicocele
Avoid Prolonged Standing/Walking: Limit periods of standing or walking for a long time.
Avoid Heavy Lifting/Straining: Refrain from heavy lifting or excessive physical exertion.
Wear Supportive Underwear: Use supportive underwear or a jockstrap.
Cold Compress: Apply a cold compress to the scrotal area.
Elevate Hips: Lie down with the hips slightly elevated.
Maintain Healthy Weight: Keep body weight within the normal range.
