I'm not sure what they were going for on this question. Is it that bilateral varicoceles are the only answer correlated with decreased sperm count? Maybe testicular atrophy? Doesn't mention anything about the testes, so not sure what to think.
"Bilateral varicoceles" is the only answer choice that is associated with male infertility and fits the description of bilateral masses palpated high in the scrotum. Scrotal varicosities increase the temperature around the testes, leading to impaired spermatogenesis.
Hydroceles are not associated with male infertility and typically involve swelling of the lower scrotum
bilateral; i would have thought a congenital defect like hydroceles but fml
