Total Motile Sperm Count in Adolescent Boys with Varicocele is Associated with Hormone Levels and Total Testicular Volume

Abstract

Total motile sperm count is inversely associated with follicle-stimulating hormone levels, and directly associated with inhibin B levels and total testicular volume. Optimized cutoffs for serum follicle-stimulating hormone, inhibin B and total testicular volume may prove to be reasonable surrogates for total motile sperm count in boys who defer semen analysis for personal or religious/cultural reasons.
