Objective: To evalute the clinical outcomes of intracytoplasmic sperm injection(ICSI) for infertility male with severe asthenospermia induced by multiple morphological anomalies of the flagella (MMAF). Methods: The clinical data of 15 patient with MMAF were retrospectively analyzed, who underwent ICSI treatment using hyponotic swelling test the "live" sperm in the Department of Reproductive Medicine of Yantai Yuhuangding Hospital from January 2011 to December 2016. Another 30 obstructive azoospermia (OA)patients are matched strictly who also accepted ICSI in the same treatment time. The two groups were compared in the couples'age, the body mass index(BMI), the duration of infertility, the retrieved oocytes, the number of ICSI oocytes, and the rates of fertilization, cleavage, transferrable embryos, good embryos, embryos implanted, clinical pregncncy, early abortion, singleton and twins. Results: After 27 cycles of ICSI, all of the MMAF patients achieved clinical pregnancy, including 11 cases of live birth, 2 cases of spontaneous abortion, and 2 cases of pregnancy maintenance. There were no significant difference between MMAF and OA groups in the couples'age and BMI, or the numbers of retrieved oocytes and ICSI oocytes( P >0.05), but the differences in the infertility duration had statistical meaning( P <0.001). No statistical differences were observed among groups in ICSI fertility rate(92.0% vs 91.6%), clesvage rate(95.4% vs 96.5%), high-quality embryonic rate(56.5% vs 57.5%), good blastocyst rate(23/61 vs 35/94), embryo implantation rate(20/48 vs 35/75), early abortion rate(4/19 vs 8/36), clinical pregncncy rate(15/27 vs 28/50), singleton rate (10/13 vs 20/25)and twinning rate(3/13 vs 5/25)( P >0.05). Conclusions: MMAF may not affect ICSI treatment outcomes, but genetic defects can be transmitted through ICSI. The affected couples should be informed of the necessity of prenatal genetic diagnosis before embryo implantation and the inevitable vertical transmission of genetic problems to the offspring.
