Comparative reproduction of the female horse, elephant and rhinoceros: implications for advancing Assisted Reproductive Technologies (ART).

Abstract: Recent loss of rhinoceros subspecies has renewed interest in using more advanced assisted reproductive technologies (ART) in rhinoceroses and elephants. Currently, only semen collection, semen preservation and artificial insemination (AI) have been used repeatedly with success in these species. Although ovum pick-up (OPU) and intra-cytoplasmic sperm injection (ICSI) have been reported in rhinoceroses, the techniques are not yet optimised. In contrast, multiple ART applications are routinely used in the horse. Since elephant and rhinoceroses share some reproductive features with equids, we postulate that procedures such as OPU, ICSI, in vitro fertilisation (IVF) and embryo transfer (ET), which are well established in the horse, may represent a basis to develop protocols for endangered pachyderms. In this review, we summarize current knowledge on reproductive physiology relevant to ART. We discuss the current state of ART in all three families and the requirements for the successful implementation of OPU, ICSI, IVF and ET in these species.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research article discusses the application of assisted reproductive technologies (ART), widely used in horses, in rhinoceroses and elephants, to help prevent the loss of rhinoceros subspecies, and advances the understanding of their reproductive physiology.

Comparative Reproduction

  • The study draws comparisons between the reproductive systems of horses, elephants, and rhinoceroses, with the aim of applying successful ART strategies from horse reproduction to elephants and rhinoceroses.
  • It points out that despite differences, elephants and rhinoceroses share some reproductive features with horses. This similarity is seen as a potential opportunity to advance the ART methods applied to these species.

State of ART in Animal Species

  • The article reviews the current application of ART in horses, elephants, and rhinoceroses.
  • In horses, multiple ART applications, like ovum pick-up (OPU), intra-cytoplasmic sperm injection (ICSI), in vitro fertilisation (IVF) and embryo transfer (ET) are regularly used with success.
  • Elephants and rhinos, on the other hand, have only been successful with basic ART processes like semen collection, semen preservation, and artificial insemination (AI). More advanced techniques like OPU and ICSI have been attempted in rhinoceroses but are not yet optimized.

Possibilities for Advanced ART

  • The researchers propose that procedures established in horses could be a foundation to develop protocols for endangered pachyderms (rhinoceroses and elephants).
  • The article discusses the requirements for successful implementation of OPU, ICSI, IVF, and ET in these species. Understanding the reproductive physiology relevant to ART is key here.
  • This is important because ART could help in the conservation efforts towards the reduction of loss of rhinoceros subspecies.
