“…In Neotropical primates, external signs of menstrual flow have been described in the genera Alouatta , Ateles , and Sapajus (Kaiser, 1947; Martin, 2012). Reports have demonstrated the occurrence of endometrial desquamation and slight bleeding at the end of the luteal phase in Sapajus apella , Sapajus macrocephalus and Sapajus robustus (Pissinatti et al, 2019). In S. apella , menstruation occurs through the constriction of straight, not spiral, endometrial arterioles (Carosi et al, 2005).…”

The ability of a species to withstand human impact depends on its life history characteristics, including social, ranging, and reproductive activity. The genera Lagothrix and Cacajao are more susceptible to anthropic action than small‐sized primates due to their slower life histories, more restricted geographical ranges, and lower population densities. This narrative literature review aimed to gather scientific information available from the last 60 years on the reproductive biology of females of the genera Lagothrix and Cacajao. Most studies on the genus Lagothrix, mainly focused on L. lagothricha and L. l. poeppigii, present important advances on reproductive strategies, reproductive productivity, functional morphology and physiology, including seasonality, sexual cycle, gestation and fetal development in captive and free‐living populations. Contrary, there is much less known about the reproductive biology of the genus Cacajao, with studies on free‐living C. calvus and C. melanocephalus highlighting reproductive behavior, and basic description of the sexual cycle, gestation, and lactation. Unfortunately, the morphology of the female genital organs is only described in C. calvus, and there is still scarce information about the menstrual activity and the placenta. This literature review encourages primatologists, morphophysiologists, reproductive specialists, and ecologists to conduct comprehensive studies of these species to better understand the gaps in knowledge about reproduction, their relationship with their environment, including climatic and social variables. Understanding the integrative reproductive biology of these species will be a clue for improving the assessment of the resilience capacity of free‐living populations and, consequently, establishing more appropriate management programs, and for the development of ex situ management techniques for the conservation of the species.

Pulmonary ultrasonography may be useful for early diagnosis and management of respiratory complications. The combination of air and soft tissues confirms imaging artifacts that may contribute to differentiation of healthy lung tissue from deteriorated lung tissue. Although non-human primates are often chosen as research models due to similarity to humans, there is a scarcity of data on the use of pulmonary ultrasound on these individuals. The aim of this study was to evaluate the contribution of ultrasound examinations of the thoracic region of Callithrix sp in diagnosing pneumopathy. Parameters were obtained from 84 Callithix sp of both sexes, aged 1.6 to 15 years and weighing 222 to 684 grams, which were caught within the Mucky Project, in Itu, São Paulo. Thoracic ultrasound examinations were conducted using the LOGIQe-R7 (GE, USA), with a 12 MHz linear transducer, at four points of both antimeres. 18 individuals presented some type of pulmonary alteration. Two of the animals with pulmonary alterations died and then underwent necropsy. Histopathological analysis showed that their lung tissue was compatible with the presence of suppurative bacterial bronchopneumonia. In the light of these cases, pulmonary consolidations diagnosed through thoracic ultrasound examination can be correlated with occurrence of pneumonia.

The Neotropical (e. g., Aotus sp., Callithrix jacchus, Saguinus sp., Saimiri sp., and Sapajus sp.) primates are important models for biomedical research and studies on reproductive physiology and biotechnology. Consequently, studies about gynecological and obstetric ultrasonography are crucial. B-mode ultrasonography is a non-invasive imaging technique that provides real-time bidimensional or three-dimensional/four-dimensional B-mode images. In association with Doppler ultrasonography, B-mode ultrasonography can also be used to monitor the mammalian blood flow to the reproductive tract during important events such as ovulation and gestation. Thus, gynecological and obstetric ultrasonography is essential for establishing the female reproductive anatomical and physiological ovarian and uterine health status, gestational diagnosis, and fetal growth monitoring. For instance, the paper presents and discusses the state-of-the-art gynecological and obstetric ultrasonography in the Neotropical primates, species that are models for biomedical research, and some recent studies on species targets for conservation strategies for wild animal populations.
