Theriogenology is a specialty of veterinary medicine concerned with animal reproduction. This includes the physiology and pathology of male and female reproductive systems of animals and the clinical practice of veterinary obstetrics, gynecology, andrology and assisted reproductive technologies (ART). Theriogenologists are veterinarians with advanced training in animal reproduction like semen analysis, evaluation and processing, breeding soundness, in vitro fertilisation (IVF), embryo transfer and obstetrics. In the United States, all theriogenologists are board-certified by the American College of Theriogenologists. The English word derives from the Greek words for beast (therio), creation (gen), and study (logos). [1]
Superfetation is the simultaneous occurrence of more than one stage of developing offspring in the same animal.
A freemartin or free-martin is an infertile cow with masculinized behavior and non-functioning ovaries. Phenotypically, the animal appears female, but various aspects of female reproductive development are altered due to acquisition of anti-Müllerian hormone from the male twin. Genetically, the animal is chimeric: karyotypy of a sample of cells shows XX/XY chromosomes. The animal originates as a female (XX), but acquires the male (XY) component in utero by exchange of some cellular material from a male twin, via vascular connections between placentas: an example of microchimerism. The chimerism is mainly present in the hematopoietic stem cells.
Bangladesh Agricultural University, abbreviated as BAU, was established in 1961. It is the first agricultural university and also the second largest public university of Bangladesh. This university is located in Mymensingh. The university has 44 departments.
Semen collection refers to the process of obtaining semen from human males or other animals with the use of various methods, for the purposes of artificial insemination, or medical study. Semen can be collected via masturbation, prostate massage, artificial vagina, penile vibratory stimulation (vibroejaculation) and electroejaculation. Semen can be collected from endangered species for cryopreservation of genetic resources.
The estrous cycle is a set of recurring physiological changes induced by reproductive hormones in females of mammalian subclass Theria. Estrous cycles start after sexual maturity in females and are interrupted by anestrous phases, otherwise known as "rest" phases, or by pregnancies. Typically, estrous cycles repeat until death. These cycles are widely variable in duration and frequency depending on the species. Some animals may display bloody vaginal discharge, often mistaken for menstruation. Many mammals used in commercial agriculture, such as cattle and sheep, may have their estrous cycles artificially controlled with hormonal medications for optimum productivity. The male equivalent, seen primarily in ruminants, is called rut.
A veterinary specialist is a veterinarian who specializes in a clinical field of veterinary medicine.

Robert Hermes is a veterinarian researcher at The Leibniz-Institute of Zoo and Wildlife Research in Berlin. He studied veterinary medicine at the Freie Universität Berlin. He completed a Ph.D. in reproductive management.
Motilal Madan is an Indian biotechnology researcher, veterinarian, academic and administrator. In a career spanning over 35 years, Madan published 432 research articles and policy papers in international and national reference journals—including 226 original research papers—and pioneered research in reproductive endocrinology, embryo biotechnology, In vitro fertilisation, and cloning.
College of Veterinary Science and Animal Husbandry, Anand is a college for the study of veterinary medicine in Anand, Gujarat, in india.
Reproductive endocrinology and infertility (REI) is a surgical subspecialty of obstetrics and gynecology that trains physicians in reproductive medicine addressing hormonal functioning as it pertains to reproduction as well as the issue of infertility. While most REI specialists primarily focus on the treatment of infertility, reproductive endocrinologists are trained to also test and treat hormonal dysfunctions in females and males outside infertility. Reproductive endocrinologists have specialty training (residency) in obstetrics and gynecology (ob-gyn) before they undergo sub-specialty training (fellowship) in REI.
Veterinary obstetrics are the obstetrical methods used in veterinary medicine, which are quite different from those of human medicine. Veterinary obstetrics is a branch of veterinary medicine that deals with medical and surgical care together with manipulations of the female animals in breeding, gestation, labor, puerperium, and care of the newborn.
Ralph Lawrence Brinster is an American geneticist, National Medal of Science laureate, and Richard King Mellon Professor of Reproductive Physiology at the School of Veterinary Medicine, University of Pennsylvania.
Guru Angad Dev Veterinary and Animal Sciences University is a veterinary university in ludhiana Punjab, india. It was a part of Punjab Agricultural University and was established on 9 August 2005 to serve the society by promoting the livestock production, health and prevention of diseases through integrated teaching and extension programs. The mission of the college is to produce veterinary graduates, scientists and extension workers for promoting better livestock health, by prevention of disease, increasing production and reproduction of livestock, thus improving the quality of rural life in Punjab.
A prosection is the dissection of a cadaver or part of a cadaver by an experienced anatomist in order to demonstrate for students anatomic structure. In a dissection, students learn by doing; in a prosection, students learn by either observing a dissection being performed by an experienced anatomist or examining a specimen that has already been dissected by an experienced anatomist.
Aglepristone is a synthetic, steroidal antiprogestogen related to mifepristone which is marketed by Virbac in several European countries for use in veterinary medicine. It is specifically used as an abortifacient in pregnant animals. Aglepristone, similarly to mifepristone, also possesses some antiglucocorticoid activity.
Stephen J. Roberts (1915–2005), also known as "Doc Roberts", was an American veterinarian, Professor at Cornell University, polo player and coach.
Gábor Vajta is a medical doctor, human pathologist and mammalian embryologist living in Cairns, Queensland, Australia. Vajta was an Honorary Professor of the BGI College, Shenzhen, China, and Adjunct Professor of the Central Queensland University, Rockhampton, Queensland, Australia. After an early career in human pathology he turned to embryology in 1989 and obtained a Doctor of Science degree in Domestic Animal Embryology at the Royal Veterinary and Agricultural University in Copenhagen, Denmark in 1999. During the past 25 years he has co-developed several patents relating to embryology, most notably the method of Handmade Cloning (HMC), the Submarine Incubation System (SIS), the Open Pulled Straw (OPS) vitrification and the Well of the Well (WOW) system. Currently Professor Vajta is director of a consulting company providing services in human and domestic animal embryology all over the world, and founder and Chief Scientific Officer of VitaVitro Biotech Co., Ltd., Shenzhen, China.
Justine K. O'Brien, an Australian zoologist, is best known for her use of reproductive research to assist in wildlife management and conservation.
Non-surgical fertility control is the prevention of reproduction without the use of surgery. The most common form of sterilization in dogs and cats is surgical, spaying in females and castration in males. Non-surgical fertility control can either result in sterilization or temporary contraception and could offer a cheaper way to keep wild dog and cat populations under control. As of 2019, only contraceptives are commercially available. Research is ongoing into methods that could result in permanent suppression of fertility.
