Data were presented as mean ± SD or frequency (percentage).
a The ICSI cycles were divided into six groups based on days of abstinence period: Group 1: 1 day abstinence, Group 2: 2 days abstinence, Group 3: 3 days abstinence, Group 4: 4 days abstinence, Group 5: 5 days abstinence, Group 6: 6-10 days abstinence
b Values with the same superscript in a row were significantly different.
