| Urine sampling in males and females. The number of black rhinoceros remaining in Kenya is estimated to be in the region of 400. Much money and effort is being spent on measures to protect and manage the few viable black rhinoceros populations remaining in Kenya within special sanctuaries or rese... |

| Steroid metabolism in different species. The reasons for the poor breeding record in captivity are unclear, but undoubtedly one of the main contributing factors is the lack of understanding of the reproductive biology of rhinoceros and of the factors required for successful reproduction.

| These are usually latex coverings filled with warm water. They provide warmth and pressure stimulation to the penis. AVs have been minimally successful in collection of semen from rhinoceroses. Lack of sustained erections in the rhinoceros has made placement of AVs difficult. Furthermore, use... |

| Semen has been cryopreserved from Rhinoceros unicornis, Ceratotherium simum, Diceros bicornis. Both pellet and straw cryopreservation methods have been used in the rhinoceros.
Poor recovery of rhinoceros sperm from freezing is indicated by low postthaw motilities (20-70%). Some improvement in ... |

| Rhinoceroses have been anesthetized for electroejaculation but only limited attempts can be made without risk to the animal. Multiple samples can be obtained with minimum or no risk to the animal by semen collection from unanesthetized rhinoceroses. |

Rhinoceroses are the most receptive to this procedure and therefore it has been the method most frequent... |

Rectal massage alone was also ineffective in producing seminal fluids from the rhinoceroses of this report. However, when rectal massage was followed with penile massage, seminal fluids were acquired... |
