目的
2
比较单精子冷冻和常规冷冻对显微取精患者的胚胎培养及妊娠影响。
方法
2
回顾性分析自2018年1月至2021年12月于中山大学附属第六医院生殖医学研究中心行显微镜取精术患者的临床资料,行单精子冷冻共39例307枚成熟卵子为单精子冷冻组,通过SPSS统计软件倾向性评分匹配女方基本助孕信息1:1匹配选择对照组,为常规冷冻组,共410枚成熟卵子,分析单精子冷冻与常规冷冻两组的受精、胚胎培养及移植后妊娠情况。
结果
2
单精子冷冻组和常规冷冻组的年龄、体质量指数(BMI)、不孕年限、基础基础卵泡刺激素(FSH)、基础黄体生成素(LH)、基础雌二醇(E2)、抗苗勒管激素(AMH)、窦卵泡计数(AFC)、获卵数、移植胚胎数等一般资料的比较,差异均差异无统计学意义(
P
>
0.05);两组的受精率、可利用胚胎率、优质胚胎率比较分别为65.8%
vs.
60.49%、67.82%
vs.
58.87%、70.80%
vs.
75.34%,差异均无统计学意义;两组的临床妊娠率为45.45%
vs.
70.0%,有统计学差异(
P
=0.049)。
结论
2
显微取精患者若获取精子极少,为增加每颗精子利用机会以及保证后续助孕精子解冻后获取精子,单精子冷冻可为有效选择,但临床妊娠率下降,因例数限制,对后续妊娠的影响还需增加例数再观察分析。
Objective
2
To compare the effects of single sperm cryopreservation and conventional cryopreservation on embryo culture and pregnancy in patients undergoing microdissection testicular sperm extraction (micro-TESE).
Methods
2
A retrospective analysis was done on the patients who underwent micro-TESE at the Reproductive Medicine Center in the Sixth Affiliated Hospital of Sun Yat-Sen University between January 2018 and December 2021. The single sperm cryopreservation group included 39 patients undergoing single sperm cryopreservation and 307 MII oocytes. The conventional cryopreservation group included 39 patients undergoing conventional cryopreservation and 410 MII oocytes. Propensity score matching (PSM) was performed to balance the selection bias. The fertility rate, embryo culture and pregnancy of these two groups were compared.
Results
2
There was no statistical difference in age, body mass index (BMI), years of infertility, basal FSH, basal LH, basal E2, AMH, AFC, number of oocytes retrieved and number of transferred embryos between the two groups (
P
>
0.05). No significant difference was found in fertilization rate (65.8% vs. 60.49%), available embryo rate (67.82% vs. 58.87%) and high-quality embryo rate (70.80% vs. 75.34%). The single sperm cryopreservation group had significantly lower clinical pregnancy rate than conventional cryopreservation group (45.45% vs. 70.0%,
P
=0.049).
Conclusion
2
If the patients undergoing micro-TESE have very few sperms, single sperm cryopreservation could be an effective choice to increase the utilization of each sperm and ensure the subsequent sperm retrieval after thawing, but the clinical pregnancy rate is decreased. Due to the limited number of cases, we need a large additional number of cases to observe and analyze.
