A varicocele may cause
Dec. 07, 2014
- Shrinkage of the affected testicle (atrophy). The bulk of the testicle comprises sperm-producing tubules. When damaged, as from varicocele, the testicle shrinks and softens. It's not clear what causes the testicle to shrink, but the malfunctioning valves allow blood to pool in the veins, which can result in increased pressure in the veins and exposure to toxins in the blood that may cause testicular damage.
- Infertility. Varicoceles may keep the local temperature in or around the testicle too high, affecting sperm formation, movement (motility) and function.
