ABSTRACT
Objective:
To investigate the efficacy and clinical outcomes of intracytoplasmic sperm injection (ICSI) with micro amount frozen-thawed diagnostic sperm obtained by microdissection testicular sperm extraction (microTESE), percutaneous epididymal sperm as-piration (PESA) and testicularsperm extraction (TESA) in the treatment of azoospermia.Methods:
A retrospective analysis was performed on 736 ICSI cycles of azoospermia patients.In Reprocluctive Medicine Center of the First Affiliated Hospital of Zhengzhou University from January 2018 to December 2019. Including 199 ICSI cycles (microTESE 47cycles, PESA 75cycles and TESA 77 cycles) with micro amount frozen-thawed diagnostic sperm and 537 ICSI cycles (microTESE 23 cycles, PESA 111 cycles and TESA 403 cycles) with fresh micro amount sperm. The general conditions, embryo development conditions and clinical outcomes of patients were compared between and within the two groups.Results:
The recovery rate of PESA group was significantly lower than that of TESA group (89.3% vs 98.7%), P<0.05. The rate of 2PN in the fresh control group was significantly higher than that in the experiment group (75.5% vs 71.3%) and the rate of 2PN in the fresh microTESE and PESA groups were also significantly higher than those of the frozen-thawed microTESE and PESA groups (74.2% vs 64.6%) and (78.5% vs 72.4%), P<0.05. Both the rate of D5 blastocyst formation and high quality blastocyst in the fresh group were significantly lower than that in the experiment group (26.9% vs 32.9%) and (15.1% vs 18.0%), P<0.05; both the rate of early cleavage and blastocyst formation in the fresh microTESE group were significantly lower than that in the frozen-thawed microTESE group (55.1% vs 68.3%) (27.3% vs 39.3%), P<0.05. Both the rate of 8 cells embryos and blastocyst formation in the fresh TESA group were significantly lower than those of the TESA frozen-thawed group (41.3% vs 46.0%) (26.5% vs 32.4%), P<0.05. There was no significant difference in pregnancy rate and planting rate between or within the groups(P>0.05). The abortion rate in the frozen-thawed group was significantly higher than the fresh group (12.0% vs 4.0%), P<0.05, especially the abortion rate in the PESA frozen-thawed group was significantly higher than the fresh group (18.0% vs 1.7%), P<0.05. There was no significant difference in gender, weight and body length between the fresh group and the frozen-thawed group (P>0.05), but there were two malformed babies born in the frozen-thawed group.Conclusions:
Frozen-thawed microinjection of diagnostic microspermatozoa is a feasible method for the treatment of asthenospermia.There was on significonty difference in pregnancy rate and planting rate between of with in the groups. However, significantly higher than the fresh PESA group of the influence on offspring needs to be further studied.
