OBJECTIVE: To assess the value of combined evaluation of serum follicle-stimulating hormone (FSH), inhibin B (INHB), chromosome karyotyping and AZF microdeletion of Y-chromosome (AZF-MD-Ych) in predicting the success of testicular sperm aspiration (TESA) in azoospermic patients.
METHODS: A total of 262 azoospermic patients were divided into two groups with normal (n=162) and abnormal (n=100) serum FSH levels. INHB levels, INHB/FSH ratio, chromosome karyotype patterns of the peripheral lymphocytes, and AZF-MD-Ych were compared between the two groups. Among the patients receiving TESA, the success rate of the procedure was compared between the two groups after excluding abnormalities in INHB, chromosome karyotype and AZF-MD-Ych.
RESULTS: Significant differences were found between the two groups in serum INHB level, INHB/FSH and chromosome karyotypes (P<0.05), but not in AZF-MD-Ych (P>0.05). After excluding the abnormalities in chromosome karyotypes, AZF-MD-Ych and INHB, sperms were obtained successfully by TESA from 61.82% (34/55) of patients with normal FSH but from none of those with abnormal FSH (P<0.01).
CONCLUSION: A combined evaluation of serum FSH, INHB, chromosome karyotypes and AZF-MD-Ych can effectively predict the success of TESA in azoospermic patients, and abnormalities in all the 4 indices suggest a very low success rate of sperm retrieval by TESA.
