The correlation analysis of testicular sperm function with reproductive hormone level and testicular vol-ume

Objective Through testicular sperm aspiration (TESA) , testicular biopsy, and detection of serum reproductive hormone levels and testicular volume in azoospermia patients, to explore the correlation between spermatogenic function of testis and serum FSH, LH, INHB levels, and testicular volume. Methods 76 cases of azoospermia patients were collected as the research objects. Chemiluminescence method was employed to detect the levels of serum reproductive hormone, and testis model was used to detect testicular volume. Routine disinfection was given to make TESA. According to TESA results, patients were divided into sperm group (group A) , and azoospermia group (group B) . According to testicular biopsy results, patients were divided into normal spermatogenic function group (group C) , sperm maturation block group (group D) , permatogenic dysfunction group (group E) , and sertoli-cell-only syndrome group (group F) . At the same time, 40 cases of healthy male were selected as the control group (group G) , and they received sperm routine examination, serum reproductive hormone and testicular volume detection. Results The level of serum FSH, LH, INHB and testicular volume in group A and C had no significant difference compared with that in group G (P>0.05) . The level of serum FSH and LH was significantly higher in group C than that in group G. The level of serum INHB and testicular volume was significantly lower than that in group G (P<0.05) . The level of serum FSH in group E was higher than in group G. The level of serum INHB in group D and E was lower than that in group G, and the difference was statistically significant (P<0.05) . Spearman correlation analysis showed that the spermatogenic function of testis was negatively correlated with serum FSH and LH levels, and positively correlated with serum INHB level and testicular volume (P<0.05) . Conclusion The detection of serum FSH, LH, INHB levels and testicular volume has important clinical value for predicting testicular spermatogenie function in azoospermia patients, and can be used to guide clinical testicular sperm aspiration.
