About

Dr. Masami Yamane is a pioneering figure in reproductive biology and micromanipulation technology, best known for developing a groundbreaking computer-controlled system for assisted fertilization. In his seminal 1992 work, "Subzonal insemination of a single mouse spermatozoon with a personal computer‐controlled micromanipulation system," Dr. Yamane introduced an automated approach using three-dimensional hydraulic micromanipulators driven by pulse motors. This innovation allowed for the precise, automatic injection of a single sperm into the perivitelline space of mouse ova, dramatically enhancing the reproducibility and control of subzonal insemination. Although his most-cited paper has accumulated 25 citations, its impact is profound within the niche of reproductive technology, laying foundational principles for modern intracytoplasmic sperm injection (ICSI) and robotic-assisted fertilization. Dr. Yamane’s work bridges engineering and biology, demonstrating how computer automation can solve delicate biological challenges. His contributions remain a key reference for researchers developing micromanipulation systems for assisted reproduction, highlighting his role as an early innovator in merging precision robotics with mammalian embryology.
