Testicular sperm aspiration has a poor effect in predicting micro-TESE outcomes in NOA patients with AZFc deletion

Table 3 Comparison of SRR between two groups

Factors	Group1 (n = 122)	Group2 (n = 59)	SRR	P
No testicular biopsy, n	72	42	63.8%
Testicular biopsy, n	48	17	73.9%	0.166^a
No obtain sperm, n	28	15	65.1%	0.855^b
Obtain sperm, n	20	2	90.1%	0.036^c

If the expected frequencies are all greater than 5, the pearson chi-square can be used directly at this point. If any of the expected frequencies are less than 5, the continuous calibration chi-square test can be used at this point
Group1 Sperm obtained during micro-TESE, Group2 No sperm obtained during micro-TESE, SRR Sperm retrieve rate
^aTesticular biopsy vs. No testicular biopsy
^bNo obtain sperm vs. No obtain sperm
^cNo obtain sperm vs. Obtain sperm
