Objective:To demonstrate that serum follicle-stimulating hormone(FSH)in men rises with age,and to explore FSH reference intervals of age-related ***:Men aged 20-50 years(n=1190)underwent semen analysis according to World Health Organization(2010)*** was frozen prior to measurement of FSH by using the Siemens ADVIA Centaur®XP immunoassay *** central 95%intervals after logarithmic transformation based on age were derived from 1037 normozoospermic *** were then applied to oligozoospermic and azoospermic *** producing azoospermic semen samples were further classified as having non-obstructive azoospermia by clinical diagnostic criteria,including genetic analysis and surgical ***:Serum FSH in normozoospermic men increased with age(P<0.05),and reference intervals were determined with 10-year brackets:21-30 years[(1.0-8.2)IU/L],31-40 years[(1.4-9.5)IU/L],41-50 years[(1.9-12.0)IU/L].The proportion of oligozoospermic men with normal FSH concentrations was less than the normozoospermic men,which in turn was lower among azoospermic men(both P<0.01).The azoospermic men were further broken down according to the nature of the azoospermia as either obstructive or non-obstructive azoospermia,and 86.4%(38/44)men with non-obstructive azoospermia had elevated serum FSH concentrations whereas only 6.7%(1/15)men with obstructive azoospermia had high FSH levels,and this was significantly different(P<0.01).Conclusions:FSH concentrations increase in men between 20-50 years,and clinical interpretation of serum FSH results in men must be made by using age-based reference intervals.
