Relationship between testicular biopsy and serum levels of LH and FSH in patients with azoospermia / 中华内分泌外科杂志

ABSTRACT

Objective Through testicular biopsy and detection of serum sex hormone levels in patients with azoospermia,to explore the relationship between spermatogenic function of testis,testicular volume and serum LH and FSH levels.Methods 80 cases of azoospermia patients adimitted from Jan.2012 to Dec.2014 were collected as the research object.Immunization method was used to detect the serum sex hormone leve,testis model was adopted to detect testicular volume,and routine disinfection was given to make testicular biopsy.According to testicular biopsy results,patients were divided into normal spermatogenic function group (group A),spermatogenic dysfunction group (group B),sertoli-cell-only syndrome group (group C);percutaneous sperm group (group D),and puncture azoospermia group (group E).At the same time,50 cases of healthy male were selected as the control group and they received sperm routine examination and sex hormone detection.Correlation between spermatogenic function of testis,testicular volume and serum LH and FSH levels were studied.Results Serum levels of LH and FSH had no significant difference among group A,group B and the control group (P＞0.05).Serum level of LH and FSH was significantly higher in group C than that in group A,group B and the control group,and the differences had statistical significance (P＜0.05).Serum level of LH and FSH in group D had no significant difference compared with that of the control group (P＞0.05).Serum level of LH and FSH in group E was significantly higher than that in group D and the control group,and the difference had statistical significance (P＜0.05).The level of LH and FSH was significantly higher in abnormal testicular group than that in normal testis group,and the difference had statistical significance (P＜0.05).Spearman correlation analysis showed that the spermatogenic function of testis was negatively correlated with serum LH and FSH levels (r=-0.473,-0.441,P＜0.05).Testicular volume was negatively correlated with serum LH and FSH levels(r=-0.643,-0.715,P＜0.05),and the difference had statistical significance.Conclusion The determination of serum LH and FSH levels has important clinical value for predicting testicular spermatogenic function in azoospermia patients,and can be used to guide clinical puncture and prognosis judgement.
