“…Among them, 21 are published in journals, and one is a book chapter. The full text of the work by Mendgen et al, (1980) was the only inaccessible one, as it is a chapter of a physical book, which is the oldest research recorded here, however, its inclusion in the scope of this scientometric analysis was validated (Zacarioti & Guimarães, 2010;Oliveri et al, 2018). The Google Academic platform was the most representative in terms of publications of this nature, with 100% (n=22) of the selected material.…”

“…It is worth mentioning that the searches on the Web of Science, Scopus and Science Direct platforms using the term Snake Artificial Insemination, presented a file in addition to the one presented in Figure 1. However, this is a correction in the nomenclature of one of the authors of the research by Oliveri et al, (2018), being published in the year 2019, and it was disregarded in this study.…”

“…With the employment of biotechnological resources, the numerical reestablishment of some taxa can be initiated from just two specimens of different sexes (Oliveri et al, 2018). In this sense, even in more emblematic situations of extinction in the natural environment, such as the classic case of the blue macaw (Cyanopsitta spixii) (Wagler, 1832), which is an endemic bird of the Caatinga Biome in Brazil, could be reverted using specimens kept in captivity.…”

Diversas espécies de serpentes encontram-se com algum grau de ameaça de extinção, gerados principalmente pela caça predatória humana, fundamentada no medo místico-religioso, e perda de habitat. Contudo, é possível evitar processos de extinção a partir da utilização de biotecnologias reprodutivas com a finalidade de produção de prole para reinserção no ambiente de ocorrência natural dessas espécies. Nesse sentido, o objetivo deste trabalho é realizar um levantamento cienciométrico sobre a reprodução assistida em serpentes, nos últimos 50 anos sem recorte geográfico. Foram realizadas buscas nas bases de dados: Web of Science, Scopus, Science Direct, Pub Med, Scielo e Google Acadêmico, utilizando os termos: snake sperm e snake artificial insemination. No total, foram selecionados 22 trabalhos relacionados à temática, sendo 21 deles publicados em 16 periódicos distintos, e um capítulo de livro. A base de dados Google Acadêmico apresentou 100% dos materiais selecionados, sendo a plataforma mais completa dentre as avaliadas. Em relação a autoria desses estudos, 19 instituições de pesquisa de cinco países participaram ativamente dessa produção. Calculamos uma média de produtividade de 0,53 estudos por ano, a partir da primeira publicação que data de 1980. A espécie Elaphe gutatta foi o modelo mais utilizado, participando de 04 (19,04%) pesquisas. Concluímos que as biotecnologias da reprodução aplicada no grupo das serpentes têm uma boa aderência em periódicos científicos, e possui elevado potencial para ser utilizado como ferramenta conservacionista no táxon, contudo, novos estudos, com metodologias mais sólidas, são necessários para validar esse recurso tecnológico, sobretudo em relação à inseminação artificial, que é o grande alvo dessa área.

Amphibians and reptiles are highly threatened vertebrate taxa with large numbers of species threatened with extinction. With so many species at risk, conservation requires the efficient and cost-effective application of all the tools available so that as many species as possible are assisted. Biobanking of genetic material in genetic resource banks (GRBs) in combination with assisted reproductive technologies (ARTs) to retrieve live animals from stored materials are two powerful, complementary tools in the conservation toolbox for arresting and reversing biodiversity decline for both amphibians and reptiles. However, the degree of development of the ARTs and cryopreservation technologies differ markedly between these two groups. These differences are explained in part by different perceptions of the taxa, but also to differing reproductive anatomy and biology between the amphibians and reptiles. Artificial fertilisation with cryopreserved sperm is becoming a more widely developed and utilised technology for amphibians. However, in contrast, artificial insemination with production of live progeny has been reported in few reptiles, and while sperm have been successfully cryopreserved, there are still no reports of the production of live offspring generated from cryopreserved sperm. In both amphibians and reptiles, a focus on sperm cryopreservation and artificial fertilisation or artificial insemination has been at the expense of the development and application of more advanced technologies such as cryopreservation of the female germline and embryonic genome, or the use of sophisticated stem cell/primordial germ cell cryopreservation and transplantation approaches. This review accompanies the publication of ten papers on amphibians and twelve papers on reptiles reporting advances in ARTs and biobanking for the herpetological taxa.

“…En animales silvestres los métodos de colección de semen varían por grupo, peces (masaje abdominal), anfibios, (masaje abdominal), reptiles -serpientes (masaje del tercio caudal ventral) y aves (masaje de la cloaca hasta proyectar los cuerpos fálicos). (Oliveri, 2018). A diferencia de los grupos previamente mencionados, el de mamíferos presenta mayor dificultad, ya que a comparación de la colecta en animales domésticos (entrenamiento de machos con ayuda de una vagina artificial), estos no se encuentran acostumbrados a estar en contacto con humanos, por lo que se necesita un manejo diferente.…”

The interest in wildlife conservation has been increasing, mainly because many species have been disappearing. The main causes of this problem are the alteration, fragmentation or loss of habitats due to human action. To counteract the disappearance of these species, ex situ techniques of assisted reproduction have been developed to preserve and increase populations of endangered species in which zoos and conservation centers participate. These techniques are made up of captive breeding, the creation of banks of genetic resources and the use of reproductive biotechnologies, which include in vitro fertilization, artificial insemination and embryo transfer. To carry out these procedures, collections of both female and male gametes are made in advance, and then fertilization (assisted or in vitro). In addition, you can find other techniques that are not yet fully developed in wild animals, due to the lack of existing information about their reproductive physiology and embryonic development. Thus, it is increasingly sought to develop the biotechnological aspect of animal reproduction. The evolution of these techniques and the implementation of protocols for the reproduction of each species will allow us to approach the possibility of reducing the number of species declared in danger of extinction.
