Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Internal medicine
  • DNA

His scientific interests lie mostly in Blastocyst, Andrology, Embryo, Internal medicine and Endocrinology. His Blastocyst study combines topics from a wide range of disciplines, such as Oviduct, Embryo culture, Zygote, Oocyte and Human fertilization. His Andrology study incorporates themes from Embryo transfer, Germinal vesicle, Gynecology, Cryopreservation and Pregnancy rate.

Patrick Lonergan has researched Embryo in several fields, including Gene expression and In vivo. He combines subjects such as Pregnancy and Ovarian reserve with his study of Internal medicine. His Endocrinology research is multidisciplinary, incorporating elements of Animal science, Conceptus and Folliculogenesis.

His most cited work include:

  • Consequences of bovine oocyte maturation, fertilization or early embryo development in vitro versus in vivo: implications for blastocyst yield and blastocyst quality. (663 citations)
  • Bovine Embryo Culture in the Presence or Absence of Serum: Implications for Blastocyst Development, Cryotolerance, and Messenger RNA Expression (450 citations)
  • Effect of follicle size on bovine oocyte quality and developmental competence following maturation, fertilization, and culture in vitro. (449 citations)

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

Patrick Lonergan mainly investigates Andrology, Embryo, Internal medicine, Endocrinology and Blastocyst. His study in Andrology is interdisciplinary in nature, drawing from both Pregnancy, Genetics, Conceptus and Reproductive technology. His Embryo research is multidisciplinary, relying on both In vitro and Gene expression.

His work deals with themes such as Lactation and Animal science, which intersect with Internal medicine. His Endocrinology research includes elements of Follicular fluid and Dairy cattle. His Blastocyst research is multidisciplinary, incorporating perspectives in In vitro fertilisation, Zygote, Oocyte, In vivo and Human fertilization.

He most often published in these fields:

  • Andrology (45.92%)
  • Embryo (30.62%)
  • Internal medicine (30.62%)

What were the highlights of his more recent work (between 2016-2021)?

  • Andrology (45.92%)
  • Embryo (30.62%)
  • Sperm (11.53%)

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

His primary areas of study are Andrology, Embryo, Sperm, Animal science and Pregnancy. His Andrology research is mostly focused on the topic Oviduct. His Embryo and Embryogenesis and Blastocyst investigations all form part of his Embryo research activities.

His Sperm research integrates issues from Fertility, Oocyte, Embryo quality, Motility and Human fertilization. His Animal science study integrates concerns from other disciplines, such as Ovulation, Semen, Ice calving and Artificial insemination. Patrick Lonergan has included themes like Pregnancy Maintenance and Internal medicine, Estrous cycle, Endocrinology in his Conceptus study.

Between 2016 and 2021, his most popular works were:

  • Interferon-tau and fertility in ruminants. (35 citations)
  • Insights into conceptus elongation and establishment of pregnancy in ruminants. (35 citations)
  • Interferon tau-dependent and independent effects of the bovine conceptus on the endometrial transcriptome† (22 citations)

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

  • Gene
  • Internal medicine
  • DNA

Patrick Lonergan mostly deals with Andrology, Conceptus, Embryo, Pregnancy and Internal medicine. Patrick Lonergan interconnects Endometrium, Transcriptome and Blastocyst in the investigation of issues within Andrology. The Conceptus study combines topics in areas such as Corpus luteum, Estrous cycle and In vivo.

His research integrates issues of Offspring and Uterus in his study of Embryo. As a member of one scientific family, he mostly works in the field of Pregnancy, focusing on Fertility and, on occasion, Genetics, Exome sequencing, Sire and Animal breeding. The study of Internal medicine is intertwined with the study of Endocrinology in a number of ways.
