Korean Journal of Obstetrics and Gynecology Vol. 53 No. 12 December 2010 조사보고서한국보조생식술의현황 : 2007년 대한산부인과학회 보조생식술소위원회 Current status of assisted reproductive technology in Korea, 2007 Korean Society of Obstetrics and Gynecology Assisted reproductive technology (ART) committee 1986 년국내에서체외수정시술에의한첫시험관아기가탄생한이래불임환자치료를위한보조생식술은날로그시술기관과시행수가증가되고있을뿐만아니라, 치료성적도괄목할만큼개선되는등불임증진단과치료에많은발전이있어왔다. 불임을치료하기위해보조생식술을시행하고있는의료기관으로부터의자료는성공적인보조생식술, 즉생아 (live birth) 의출산을가능하게하는여러가지요소들에대한풍부하고귀중한자료가될수있다. 각의료기관별의치료성적은그자체로도의미가있지만성공률과성공에영향을주는요소에대한통합적인분석을위해서는국내의여러의료기관으로부터의자료를취합하여국내통계를구해보는것이의미가있을것이며, 이러한조사는국내불임환자및보조생식술시술기관의실태파악에도움을주는것은물론궁극적으로국내보조생식술에관한전체적이고일관성있는자료를장기적으로처리분석하여불임증치료의방향까지제시할수있을것으로기대된다. 1993 년 5월제정된인공수태윤리에관한선언에의하면, 인준된인공수태시술의료기관은그시술내용을연 1회 접수일 :2010. 7. 9. 채택일 :2010. 8. 6. 교신저자 : 최영민 E-mail:ymchoi@snu.ac.kr 이상대한의사협회 ( 또는동협회가지정한관련학회 ) 에보고하도록되어있으며, 1994 년본학회내에인공수태시술의료기관심사소위원회가설치되었다. 그리고 2005 년부터는 생명윤리및안전에관한법률 이시행되어모든배아생성의료기관은보건복지부의인준을받도록되어있으며, 2009 년 7월현재 155 개기관이인준되어있다. 대한산부인과학회에서는 1992 년부터국내보조생식술의현황을조사하여보고하여오고있으며, 이러한조사사업의일환으로 2007 년도보조생식술현황도조사하여이에보고하게되었다. 본조사에의해얻어진국내보조생식술에대한자료는불임환자및보조생식술시술기관의실태파악에도움을주는것은물론더나아가서는시술방법의계속적인개선과발전, 부작용의감소와임신성공률의향상을도모하는데유용한자료로활용될것이다. 본조사연구는대한산부인과학회의재정지원하에수행되었으며, 실무에서많은노력을기울인대한산부인과학회의직원여러분들과서울대학교병원의김재원, 박주희선생님, 자료정리에애써주신서울대학교병원전공의및전임의선생님들, 그리고본조사에협조하여주신국내각배아생성의료기관의여러분들께본위원회에서는깊은감사의말을전하고자한다. 2010년 8월 - 1052 -
