ABSTRACT
Research on Neotropical primates' reproduction is necessary due to the lack of available information and the increasing threat to these species. Callimico goeldii is listed as Vulnerable on the IUCN Red List of Threatened Species. This study aimed to test rectal electrostimulation for semen collection and evaluate seminal characteristics. Therefore, semen from 6 captive Goeldi's monkeys was collected and, for the first time, seminal characteristics are described. Coagulum formation was noted in all ejaculates, and we obtained partial or complete liquefaction of the samples. Results were (means ± SD) volume = 26.9 ± 11.87 µL; pH = 7.61 ± 0.28; concentration = 143.18 ± 174.96 × 106 spermatozoa/mL; total sperm motility = 83.33 ± 5.16%; linear progressive motility = 46 ± 24.08%; plasma membrane integrity = 36.38 ± 16.11%; acrosome integrity using fast-green/bengal-rose staining = 63.41 ± 11.72%, and kit Spermac® = 69.36 ± 11.81%; abnormal sperm = 72.5 ± 17.7%, with 16.2 ± 7.7% major defects and 56.3 ± 10% minor defects; sperm with high mitochondrial activity class I = 16.45 ± 22.25%. Rectal electrostimulation was an efficient method for semen collection in this species. Investigations are required to improve semen collection and handling, including cryopreservation methods.
