P<0.05 was considered to be statistically significant.

Note: Sperm with progressive motility, including those that move fast in a straight line (grade a) and that move forward but tend to travel in a curved or bent motion (grade b). MII oocytes rate = M II oocytes/total oocytes in the ICSI cycle; normal fertilisation rate = 2PNs /total M II oocytes in the ICSI cycle or 2PNs/total oocytes in the IVF cycle; abnormal fertilisation rate = 1PNs + multi-PNs/total M II oocytes in the ICSI cycle or 1PNs + multi-PNs/total oocytes in the IVF cycle.
