Methods: Total concentrations of urinary FSH were measured in a groupof 44 men at the University of California, Davis (UCD) and were compared to FSH measurements in serum. On thebasis of these and other published data, a urinary FSH value of >2 ng/mg creatinine (Cr) was selected as the cutoffpoint to identify men with elevated serum FSH ( > 12 IU/L) or low sperm counts ( < 20 million/mL). Results: Thesensitivity and specificity of this algorithm for detecting elevated serum FSH in a group of 58 agricultural workers in thePeople's Republic of China were 100 % and 50 %, respectively. The sensitivity and specificity of this algorithm fordetecting low sperm counts in a population of 105 infertility patients at UCD were 58 % and 76 %, respectively.Conclusion: This test may have particular value in identifying populations with no evidence of testicular toxicity, andin which labor-intensive semen studies may not be feasible.展开更多
