“…Furthermore, in humans, the higher platelets observed in women 82,83 can be associated with the importance of platelet aggregation as possibly a mechanism to prevent heavy menstrual bleeding 84 . Since menstrual cycles have been described in both howler and capuchin monkeys, 85,86 this result may indicate an early adaptation in female primates.…”

Non-human primates (NHPs) have various behavioral and physiological similarities to humans and are useful in evolutionary studies and in biomedical research. 1 Among platyrrhine primates, capuchin monkeys (genus Sapajus) stand out in pharmacology and neuroscience studies, 2,3 while howler monkeys (genus Alouatta) have been used in studies on infectious and parasitic diseases. 4,5 Although both species have sexual dimorphism, 6 they differ in average body mass (~5 kg for females and ~7.8 kg for male howler monkeys; ~3 kg for females and ~4 kg for male capuchins), 7 the average lifespan in captivity (26 years for howlers; up to 50 years for capuchins), 8,9 and diet. Howler monkeys are mainly folivores, with a diet rich in young leaves, shoots, buds, and different types of fiber and supplemented with fruits, seeds, and insects. [10][11][12] In contrast, capuchin monkeys have greater dietary diversity, with a

“…However, to our knowledge, studies focusing on primate reproduction and application of biotechnology are limited to certain genera, such as Callithrix , Aotus , Saimiri , and Sapajus (de Lima Cardoso et al, 2021; Mayor et al, 2019; Monteiro et al, 2023; Tardif et al, 2012). Researchers are often hampered by a lack of basic biological data, and extrapolate from reproductive information generated in other taxa when applying ARTs.…”

“…However, the maintenance of wild species in captivity can produce important reproductive variations due to multiple factors, such as stress, availability of resources, territories, and the composition of social groups (Mayor et al, 2017). Previous research has described different presentations of the sexual cycle depending on the primate species; while the menstrual cycle has been identified in Alouatta guariba clamitans (Silvestre et al, 2017) and genera Aotus , Cebus and Sapajus (de Lima Cardoso et al, 2021; Mayor et al, 2019), Callithrix (Abbott, 1992) and Saimiri (Srivastava et al, 1970) have estrous cycles. However, reproductive knowledge is still absent for many medium‐ and large‐sized primates, such as woolly monkeys (genus Lagothrix ) and uakaris (genus Cacajao ).…”

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.

“…Owl monkeys are monogamous [ 9 ], while capuchin monkeys are polygamous [ 10 ]. Their shared reproductive characteristics include the presence of a menstrual cycle [ 4 ] and the ability to easily reproduce in captivity [ 11 ]. In both species, it has been observed that during follicular maturation, granulosa cells, theca cells, and oocytes develop a process of cellular death, resulting in follicular atresia and selection, which regulates the ovulation rate and restricts their reproductive potential [ 12 , 13 ].…”

This study evaluated the follicular atresia, cell proliferation, and anti-Mullerian hormone action in Aotus nancymae and Sapajus macrocephalus during three sexual phases (follicular, luteal, and gestational). Follicular quantification and immunolocalization of Caspase-3 protein, B-cell lymphoma 2 (BCL-2), proliferating cell nuclear antigen (PCNA), and anti-Mullerian hormone (AMH) were performed. A significant difference in the quantification between preantral and antral follicles, with a progressive decrease in the antrals, was identified. Protein and hormonal markers varied significantly between follicle cell types (A. nancymae p = 0.001; S. macrocephalus, p = 0.002). Immunostaining in the preantral and antral follicles was present in all sexual phases; for Caspase-3, in granulosa cells, oocytes, and stroma; for BCL-2, in granulosa cells, oocytes, and theca; and for PCNA and AMH, in oocytes and granulosa cells. The immunostaining for Caspase-3 was more expressive in the preantral follicles (follicular phase, p < 0.05), while that for BCL-2 and PCNA was more expressive in the antral follicles of the follicular phase. The AMH was more expressive in the primary and antral follicles of nonpregnant females, in both the follicular and luteal phases. Our results contribute to understanding the ovarian follicular selection, recruitment, and degeneration of these species.
