摘 要:目的:观察无精子症和严重少/弱精子症患者借助卵胞质内单精子注射(ICSI)技术出生的子代与其他精子ICSI/体外受精(IVF)子代的出生缺陷情况。方法:将接受ICSI/IVF治疗的237对夫妇生育的300例子代按ICSI/IVF当日精液情况和受精方式分为附睾/睾丸精子ICSI组(A组,患者92例,子代118例)、严重少/弱精子ICSI组(B组,患者84例,子代106例)、非严重少/弱/畸形精子ICSI组(c组,患者35例,子代42例)、正常精子IVF组(D组,患者26例,子代34例)。对召回现场随访的子代进行出生缺陷病史询问、超声检查和无精子症因子(AZF)基因检测。结果:受访子代平均年龄为33.1±20.3(4-84)个月,新生儿出生缺陷率为1.7%(5/300),总出生缺陷率为4.7%(14/300),4组的出生缺陷率分别为5.1%(6/118)、3.8%(4/106)、2.4%(1/42)和8.8%(3/34),组间无统计学差异(P〉0.05)。112个家庭AZF基因检测显示B组有3对父子存在同样位点的AZF基因微缺失。结论:无精子症和严重少/弱精子症等严重男性不育症患者ICSI子代的出生缺陷发生率与其他较好精子或正常精子IVF子代相比无明显增加,AZF基因检测没有新增缺失位点和新增缺失病例。Objective: To evaluate the incidence of congenital defects from severe oligoasthenoterato-zoospermia and azoospermia patients' offspring. Methods: Totally 300 offsprings from 237 infertile couples treated by intracytomic plasma sperm injection/in vitro fertilization (ICSI/IVF) accepted face-to-face followed up and physical examination. All 300 children were retrospectively divided into 4 groups according to the stratification of their fathers' sperm used for ICSI or IVF. Group A: epididymal or testicular sperm used for ICSI (including 118 children from 92 couples); group B: sperm from severe oligoasthenoteratozoospermia for ICSI (including 106 children from 84 couples); group C: other cases undergone ICSI (including 42 children from 35 couples); group D: normal sperm used for IVF (including 34 children from 26 couples). Results: All children aged 33.1 ± 20.3 (4-84) months. The incidence of newborn congenital defects was 1.7% (5/300) and total congenital defects was 4.3% (13/300). No significant difference was found among four groups regarding to the incidence of congenital defects [4.2% (5/118), 3.8% (4/106), 2.4% (1/42) and 8.8% (3/34)]. Only 3 pairs of father and son from group B were found sharing the same congenital defect--azoospermia factor (AZF) microdeletion. Conclusion: Incidence of congenital defects as well as AZF microdeletion in offsprings of ICSI using spermatozoa from severe oligoasthenoteratozoospermia or azoospermia are comparable to those showing better sperm quality.
