Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Enzyme
  • DNA

His primary areas of study are Sperm, Andrology, Hamster, Cell biology and Human fertilization. His Sperm study integrates concerns from other disciplines, such as Sperm-Ovum Interactions and Zona pellucida. His Andrology research integrates issues from Microinjection, Anatomy, Oocyte, Embryo and Intracytoplasmic sperm injection.

His Hamster study combines topics in areas such as Ultrastructure, Oviduct, Biochemistry, Motility and Wheat germ agglutinin. In the subject of general Cell biology, his work in Zona free is often linked to Protamine, thereby combining diverse domains of study. Ryuzo Yanagimachi has researched Human fertilization in several fields, including Ovulation and Botany.

His most cited work include:

  • Full-term development of mice from enucleated oocytes injected with cumulus cell nuclei (2068 citations)
  • Intracytoplasmic sperm injection in the mouse. (910 citations)
  • The Use of Zona-Free Animal Ova as a Test-System for the Assessment of the Fertilizing Capacity of Human Spermatozoa (803 citations)

What are the main themes of his work throughout his whole career to date?

Ryuzo Yanagimachi focuses on Sperm, Andrology, Cell biology, Human fertilization and Hamster. The Sperm study combines topics in areas such as Biochemistry and Pronucleus. He has included themes like Oocyte, Embryo, Intracytoplasmic sperm injection and Anatomy in his Andrology study.

His work deals with themes such as Metaphase, Meiosis and Spermatid, which intersect with Cell biology. He interconnects Immunology and Sperm-Ovum Interactions, Zona pellucida in the investigation of issues within Human fertilization. Ryuzo Yanagimachi combines subjects such as Oviduct and Insemination with his study of Hamster.

He most often published in these fields:

  • Sperm (42.08%)
  • Andrology (41.30%)
  • Cell biology (27.53%)

What were the highlights of his more recent work (between 2003-2020)?

  • Andrology (41.30%)
  • Sperm (42.08%)
  • Cell biology (27.53%)

In recent papers he was focusing on the following fields of study:

The scientist’s investigation covers issues in Andrology, Sperm, Cell biology, Genetics and Embryo. His Andrology research includes themes of Offspring, Oocyte, Intracytoplasmic sperm injection and Anatomy. His studies deal with areas such as Spermatozoon and Embryogenesis as well as Oocyte.

His Sperm research incorporates elements of Zoology, Sperm entry, Spermatogenesis and Human fertilization. His Cell biology study incorporates themes from Germ line development and Sexual differentiation. His Embryo research is multidisciplinary, incorporating perspectives in Molecular biology and Immunology.

Between 2003 and 2020, his most popular works were:

  • Intracytoplasmic injection of spermatozoa and spermatogenic cells: its biology and applications in humans and animals. (151 citations)
  • Transition nuclear proteins are required for normal chromatin condensation and functional sperm development. (144 citations)
  • Freeze-Dried Sperm Fertilization Leads to Full-Term Development in Rabbits (143 citations)

In his most recent research, the most cited papers focused on:

  • Gene
  • Enzyme
  • DNA

His main research concerns Andrology, Sperm, Genetics, Embryo and Intracytoplasmic sperm injection. His research integrates issues of Offspring, Oocyte, Embryogenesis and Human fertilization in his study of Andrology. His study in Human fertilization is interdisciplinary in nature, drawing from both Insect, Botany and Motility.

His research in Sperm intersects with topics in Immunology, Acephalic spermatozoa, Spermatogenesis and Cell biology. As a member of one scientific family, Ryuzo Yanagimachi mostly works in the field of Cell biology, focusing on Embryonic stem cell and, on occasion, Hamster, Stem cell and Y chromosome. His work in Acrosome tackles topics such as Acrosome reaction which are related to areas like Vitelline membrane and Zona pellucida.
