His primary areas of study are Oocyte, Blastocyst, Cryopreservation, Human fertilization and Embryo. In general Oocyte study, his work on In vitro maturation often relates to the realm of Oxygen tension, thereby connecting several areas of interest. Takashi Nagai has included themes like In vitro and Vitrification in his Blastocyst study.
His work carried out in the field of Human fertilization brings together such families of science as Sperm and Polyspermy. Takashi Nagai has researched Embryo in several fields, including Oxidative stress, Biochemistry, Oviduct, Glutathione and Immunology. As a part of the same scientific study, Takashi Nagai usually deals with the In vitro fertilisation, concentrating on Embryo transfer and frequently concerns with Zygote.
Takashi Nagai spends much of his time researching Blastocyst, Oocyte, Embryo, Human fertilization and In vitro. The various areas that Takashi Nagai examines in his Blastocyst study include In vitro fertilisation, Vitrification, Immunology and Cryopreservation. He is interested in In vitro maturation, which is a branch of Oocyte.
His In vitro maturation research is multidisciplinary, incorporating perspectives in Follicular phase and Germinal vesicle. His study in Embryo is interdisciplinary in nature, drawing from both Molecular biology and Biochemistry. His Human fertilization research includes elements of Sperm and Polyspermy.
His main research concerns Oocyte, Blastocyst, Pesticide, Human fertilization and Cryopreservation. Particularly relevant to In vitro maturation is his body of work in Oocyte. His Blastocyst study contributes to a more complete understanding of Embryo.
In his work, Tributary, Pesticide residue, Passive sampling and Sampling is strongly intertwined with Environmental chemistry, which is a subfield of Pesticide. As part of the same scientific family, Takashi Nagai usually focuses on Human fertilization, concentrating on Sperm and intersecting with Artificial insemination and Semen. His study looks at the relationship between Cryopreservation and fields such as Vitrification, as well as how they intersect with chemical problems.
Takashi Nagai mainly focuses on Oocyte, Environmental chemistry, Pesticide, Blastocyst and Cryopreservation. The Environmental chemistry study combines topics in areas such as Ecology and Aquatic organisms. Takashi Nagai combines subjects such as In vitro fertilisation, In vitro maturation and Human fertilization with his study of Blastocyst.
His work deals with themes such as Sperm, Embryo transfer, Embryo and In Vitro Oocyte Maturation Techniques, which intersect with Human fertilization. His Cryopreservation study incorporates themes from Vitrification and Germinal vesicle. His Vitrification research is multidisciplinary, incorporating elements of Immunology, Reproductive technology, Embryogenesis, Gamete and Cryoprotectant.
