Does left varicocele generally affect fertility?

The condition of left varicocele has a certain impact on fertility, because the left varicocele will lead to a decrease in the ability of the testicles to synthesize sperm, and will also cause blood to accumulate on the spermatic duct, seriously affecting the secretion of sperm, which is very related to conception. For the condition of left varicocele, we recommend that you should receive treatment in time to avoid affecting your life as a couple.

When the varicocele is varicose to a certain extent, it will affect the quality of sperm and thus fertility. The increased temperature of the scrotum will affect the ability of the testicle to produce sperm, or cause testicular hypoxia, nutritional disorders, testicular endocrine dysfunction and toxins. The destructive effect of oxygen free radicals will affect the occurrence and function of sperm.

The causes of infertility caused by varicocele include:

① Varicose veins can cause blood stasis in the varicocele, which can cause the temperature in the scrotum to rise, and the testicular temperature can rise by 1℃~2℃. If the temperature continues to rise for a long time, it can affect the production of sperm in the testicles, leading to azoospermia and oligospermia; the epididymis is also not conducive to the maturation of sperm. However, sperm production disorders mainly occur at the primary spermatocyte and spermatocyte stages.

② Blood stasis, increased pressure in the spermatic vein, lack of oxygen and nutrients, affect the clearance of metabolic products, thereby affecting sperm development and maturation.

③ When the left spermatic cord is varicose, blood refluxes, bringing substances produced by the adrenal glands and kidneys, such as steroids, catecholamines, 5-hydroxytryptamine, and prostaglandins, to the testicles. 5-hydroxytryptamine is one of the toxins and has a toxic effect on the testicles. Prostaglandins reduce testicular blood circulation, increase epididymal contraction, are not conducive to sperm maturation, and affect sperm motility.

④ Varicose veins damage the interstitial cells of the testicles, reducing testosterone secretion and peripheral blood testosterone levels, while blood follicle-stimulating hormone (FSH) and interstitial cell stimulating hormone (ICSH) increase, causing endocrine disorders and interfering with the occurrence and maturation of sperm.

In order to let male friends better understand that left varicocele has an impact on fertility, I hope you can pay attention to the symptoms of this disease in your life and take timely treatment. For varicocele, as long as we take medicine according to the doctor's advice in life, it can be cured.
