上海市第一人民医院辅助生殖医学科再传喜讯。记者5月31日从该院获悉,该院生殖中心和泌尿外科男科亚专科联合狙击男性不育,日前国内第一例通过单精子冷冻技术成功孕育的试管婴儿在该院顺利降生,宝宝健康,母子平安。据称,这不仅是国内首例,且在世界范围内也是严重男性不育治疗领域的重大突破。

据了解,宝宝的父亲是38岁的非梗阻性无精症(NOA)患者,于外院就诊多年未见成效。2015年上半年,这位患者求助市一医院李铮教授,并至市一医院泌尿中心男科就诊。在全面了解患者病情经过后,结合体检结果,专家建议药物治疗一定阶段后,实施显微镜下睾丸切开取精术,手术顺利。在取得极少量精子后,将之转移至市一松江南部的辅助生殖科,采用单精子冷冻技术保存精子20条,复苏后行单精子卵胞浆内注射(ICSI)治疗。第一次尝试后女方即获得单胎妊娠,5月10日诞下一健康男婴,体重4750克,母子平安。

李铮教授介绍说,所谓单精子冷冻技术,是指将严重少精子症或无精子症男性患者经过治疗或手术后取得的极少量的精子逐个挑选出来,加载在特殊的载体上后放入零下196℃液氮进行保存的技术。通过新载体cropiece实施此项技术,以成功达成患者夫妇拥有健康宝宝的梦想。

据了解,对于严重男性不育患者能否成功取到精子存在不确定性,临床上为避免因取精失败而导致取消ICSI周期,一般将取到的精子冷冻保存,在女方取卵当日解冻后挑选存活精子进行ICSI治疗,这是目前采用的基本策略。然而由于精子数量太少、活力太差,对于极少量精子的冷冻保存目前在世界范围内是个难题。一般的冷冻技术无法保证这类患者精子能顺利回收以及复苏后的存活。

尽管有不少文献报道了各种单精子冷冻方法,但大多还处于实验室研究阶段。仅有的出生婴儿的报道也存在生物污染和使用复苏后不活动精子等伦理问题,因而限制了在临床的应用。在市一辅助生殖医学科主任吴煜和李铮教授的指导下,市一专家团队前期与第九人民医院薛松果博士合作开发单精子冷冻技术,经过研究和改良后进一步用于临床,目前已采用此法冻存了36例患者精子,其中6人进行了进一步ICSI治疗,复苏后精子回收率达到86.27%,存活率近30%。除了已呱呱坠地的第一例外,另有一例单胎妊娠、一例双胎妊娠中。
