A varicocele is an enlargement of the veins within the scrotum that drain blood from the testicles. It is a common condition that may contribute to male infertility in some individuals. Although the exact mechanism by which varicoceles affect fertility is not fully understood, factors such as increased testicular temperature and altered blood flow may play a role. In certain cases, varicoceles may be associated with reduced sperm count, motility, or quality. Depending on the severity of the condition, semen analysis results, and individual fertility evaluation, surgical treatment known as varicocelectomy may be considered.
