Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Internal medicine
  • Genetics

George E. Seidel spends much of his time researching Andrology, Sperm, Sexing, Embryo and Semen. His Andrology research integrates issues from In vitro, Cryopreservation, Blastocyst, Oocyte and Human fertilization. George E. Seidel interconnects In vitro fertilisation, Internal medicine and Artificial insemination in the investigation of issues within Sperm.

His Artificial insemination course of study focuses on Fertility and Pregnancy, Cell separation, Offspring and Genetics. His Sexing study combines topics from a wide range of disciplines, such as Embryo cryopreservation, Mammalian sperm, Biotechnology, Flow cytometry and Animal science. The Embryo study which covers Fetus that intersects with Prostaglandin, Follicle-stimulating hormone, Serum gonadotrophin, Transgene and Microinjection.

His most cited work include:

  • Insemination of heifers with sexed sperm (252 citations)
  • Current status of sexing mammalian spermatozoa (236 citations)
  • Superovulating cows with follicle stimulating hormone and pregnant mare's serum gonadotrophin (209 citations)

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

His primary areas of study are Andrology, Sperm, Embryo, Internal medicine and Endocrinology. George E. Seidel has included themes like Anatomy, Human fertilization, Cryopreservation, Blastocyst and Oocyte in his Andrology study. George E. Seidel combines subjects such as In vitro fertilisation, Fertility and Semen with his study of Sperm.

His work in Semen addresses subjects such as Sexing, which are connected to disciplines such as Mammalian sperm. His work carried out in the field of Embryo brings together such families of science as In vitro and Biotechnology. His work in Insemination addresses issues such as Artificial insemination, which are connected to fields such as Animal science.

He most often published in these fields:

  • Andrology (47.73%)
  • Sperm (26.99%)
  • Embryo (24.15%)

What were the highlights of his more recent work (between 2008-2021)?

  • Andrology (47.73%)
  • Animal science (11.65%)
  • Sperm (26.99%)

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

The scientist’s investigation covers issues in Andrology, Animal science, Sperm, Reproductive technology and Internal medicine. His biological study spans a wide range of topics, including Anatomy, Human fertilization, Cryopreservation, Embryo and Blastocyst. The study incorporates disciplines such as Pregnancy, Pregnancy rate, Insemination and Artificial insemination in addition to Animal science.

George E. Seidel focuses mostly in the field of Sperm, narrowing it down to topics relating to Fertility and, in certain cases, Sexing. His Reproductive technology research also works with subjects such as

  • Embryo culture and related Immunology and Ovulation,
  • Reproductive biology and related Sperm motility. His Internal medicine research includes elements of Urea, Endocrinology, Oogenesis and Forskolin.

Between 2008 and 2021, his most popular works were:

  • New Technologies in Animal Breeding (121 citations)
  • Pregnancy rates in heifers and cows with cryopreserved sexed sperm: effects of sperm numbers per inseminate, sorting pressure and sperm storage before sorting. (99 citations)
  • Update on sexed semen technology in cattle (64 citations)

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

  • Gene
  • Genetics
  • Internal medicine

George E. Seidel focuses on Andrology, Sperm, In vitro fertilisation, Artificial insemination and Embryo. His Andrology research is multidisciplinary, incorporating perspectives in In vitro, Zygote, Cryoprotectant, Cryopreservation and Blastocyst. His research in Sperm intersects with topics in Fertility, Semen, Human fertilization and Sexing.

His studies examine the connections between Fertility and genetics, as well as such issues in Insemination, with regards to Beef cattle. His study focuses on the intersection of Artificial insemination and fields such as Animal science with connections in the field of Estrus Detection and Pregnancy rate. His research integrates issues of Imprinting, Epigenetics and Anatomy in his study of Embryo.
