精液的宫内授精(IUI)普遍用于治疗广范的不育疾病。本研究比较IUI前5种精液制备技术:①精液洗涤法:清除精子获能的抑制物和前列腺素。②上游法、下游法和Per-coll梯度离心法:这些先进的制备技术清除无活力精子、白细胞及碎屑。③肝素孵育冷冻法:化学刺激精子获能。研究目的在于明确用丈夫的精液进行人工授精的患者中,是否任何先进的制备技术较精液洗涤法产生较高的妊娠率(PR)。结果肯定,哪一种精液制备产生最高的PR。 363例接受同源人工授精的参与者被随
Intrauterine insemination of semen (IUI) is generally used to treat a wide range of infertility diseases. This study compared the top five IUI semen preparation techniques: ① Semen washing method: Remove the sperm-inhibitory substances and prostaglandins. ② upstream, downstream and Per-coll gradient centrifugation: These advanced preparation techniques remove inactive sperm, white blood cells and debris. ③ heparin incubation freezing method: chemical stimulation of sperm capacitation. The aim of the study was to determine if any advanced preparation technique produced a higher pregnancy rate (PR) than semen washing in patients who had her husband’s sperm inseminated. The result is certain, which semen is produced to produce the highest PR. 363 participants who received homologous artificial insemination were followed
