摘要:

目的 探讨中年男性精子DNA碎片率(DFI)与精液质量和体外受精胚胎移植妊娠结局的关系。 方法 共收集180例接受常规体外受精胚胎移植治疗且男性年龄>38岁的精液标本。根据DFI的阈值分成(<30%和≥30%)两组。主要测量指标包括:常规精液参数、激素水平、DFI、受精率、优质胚胎率、临床妊娠率等。结果   通过比较分析发现,DFI与男性卵泡刺激素(FSH)、精子活力、精子形态密切相关,且精子活力随着DFI水平的升高而下降(P<0.05);当DFI≥30%时,优质胚胎率下降(P<0.05),但两组的临床妊娠率差异无显著性(P>0.05)。 结论 DFI可以作为中年男性精液常规分析的重要参考指标,虽然DFI影响优质胚胎率,但与辅助生殖治疗的临床妊娠结局无关。

Abstract:

Objective To explore the relationship between sperm DNA fragmentation index(DFI) and sperm quality, as well as in vitro fertilization-embryo transfer (IVF-ET) preganancy outcomes in middle-aged men. Methods   A total of 180 semen specimens from males aged over 38 years who received comventional IVF-ET treatment were collected and divided into two groups(<30% and ≥30%) based on the DIF threshold. Main measures result including: normal semen parameters, hormone levels, DFI, fertilization rate, good quality embryo rate and pregnancy rate. Results  DFI was closely related to male follicle-stimulating hormone(FSH), sperm motility,morphology, and the sperm vitality decreased with increasing DFI level (P<0.05). When DFI≥30%, the rate of high-quality embryos decreased (P<0.05), but there was no significant difference in the pregnancy rate (P>0.05). Conclusion DFI can serve as an important indicator for routine analysis of semen in middle-aged men. DFI affects the rate of high-quality embryos, but it is not related to the clinical pregnancy outcome of assistant reproduction technology (ART).
