试管婴儿技术

近些年随着环境与空气污染加剧、生活作息不规律以及食品卫生状况差等因素的相互作用,不孕症的发生率呈逐步上升的趋势,而发生不孕的夫妻中,又以女方原因较为常见,约占30-50%.男性因素引起的不学约占33%,另有17%的病例夫妻双方均存在异常.正常受孕出现问题之后,就需要铺助生殖技术来帮助这些夫妻拥有一个宝宝,

1978年世界上第一个试管婴儿在英国诞生,创造这一医学奇迹的罗伯特・爱德华兹因为在体外受精技术领域的开创性贡献而获得了2010年诺贝尔医学奖。从1978年至今.体外受精技术的发展已经有了三十几年的历史

第一代试管婴儿技术

IVF( in Vitro Fertilization)是将精子和卵子放在同一个培养基中,让它们自然结合.即所谓的常规受精,主要是针对女性因素引起的不孕。但由于各种原因,经常会出现受精失败

第二代试管婴儿技术

是ICSI技术( Intracytoplasmic Sperm Injection),最早的成功案例由比利时的 Palermo医师在1992年操作完成,ICSI是卵浆内单精子注射,这项技术可以解决常规受精失败的问题.因此提高了IVF的成功率.对于重度少弱精以及需睾丸取精的男性不孕症患者的治疗具有里程碑的意义

第三代试管儿技术

是应用PGD/PGS技术( Preimplantation Genetic Diagnosis)在移植前对胚胎进行基因诊断,可以对相关遗传疾病进行筛查,如地中海贫血症。唐氏综合症等常见病,以及猫叫综合症,脊髓型肌菱缩等少见病,第三代PGD/PGS技术已经可有效筛查出至少100多种遗传病
