Outline of Research at the Start

不妊治療の需要が年々高まっているが,現在,病院やクリニックでは,胚(受精卵)を扱う専門職である胚培養士が圧倒的に足りていない.本研究では,胚培養士に頼ることなく,誰もが微細操作(顕微授精)を行うことを可能とする技術開発を目指し,着衣型能動デバイスによる全身動作の誘導・感覚呈示を含む没入型微細操作インタフェースの開発とイマーシブ・ミクロスペースの創成を試みる.初学者がイマーシブ・ミクロスペースを介して動物胚の操作を行った場合と胚培養士が従来の装置を用いて操作を行った場合とを比較し,操作精度やタスク時間,胚の発生率が同程度となるか,行動神経科学と生殖工学に基づく検証も行う.

Outline of Final Research Achievements

The demand for infertility treatment has been increasing year by year, but currently, there is a severe shortage of embryologists, the specialists who handle embryos (fertilized eggs) in hospitals and clinics. This research aims to develop technology that enables anyone to perform micromanipulation (intracytoplasmic sperm injection) without relying on embryologists. The study focuses on the development of an immersive micromanipulation interface that includes guidance of full-body movements and sensory feedback through a wearable active device, as well as the creation of immersive microspaces. To promote immersion into immersive microspaces, a device for sensory recall using a wearable active device was developed, and its effectiveness was demonstrated through statistical analysis.

Academic Significance and Societal Importance of the Research Achievements

日本産科婦人科学会によると,不妊治療で古くから行われている体外受精法よりも精子を卵子の中に直接注入する顕微授精法が選択されることが多くなっているが,顕微授精の操作には熟練を要する.そのため,不妊治療においては,「胚培養士」と呼ばれる,胚(受精卵)を扱う専門職が存在するが,胚培養士の存在を必要とする病院やクリニックでは,圧倒的に胚培養士の数が足りていないという現状がある.胚培養士不足を解決する技術開発は,重要な社会課題の1つであろう.本研究の成果は初学者であっても,微細な操作を可能とするものであり,需要が高まっている不妊治療へ貢献する技術として重要である.
