Table 4 ICSI outcome according to the severity of the oligozoospermia
From: In cryptozoospermia or severe oligozoospermia is sperm freezing useful?
Cryptozoospermia (group 1) n = 36 | Very severe oligozoospermia (group 2) n = 50 | Severe oligozoospermia (group 3) n = 83 | P value (group 1 vs 2) | P value (group 1 vs 3) | P value (group 2 vs 3) | ||||
