Microscopic anatomy of the ovary ofAlouatta caraya

Abstract

ABSTRACT. The microscopic structure of the Alouatta caraya ovary is studied in different ages and reproductive stages. The most significant feature seems to be the presence in adult ovaries of abundant glandular interstitial tissue which occupies both the cortex and medulla. It seems to be derived from the theca interna of atretic follicles. Discrete luteinized masses are present in the medulla in all the ovaries observed. Invaginations of the surface epithelium are seen only in infant and juvenile ovaries. The development of cystic follicles seems to be a common pathway of atresia.

Observations on the female internal reproductive organs of the brown howler monkey (Alouatta guariba clamitans)

“…This feature has also been found in other genera and species of neotropical primates [Castellanos & McCombs, 1968;Eckstein, 1958;Guraya, 1968Guraya, , 1974Hertig et al, 1971;Wislocki, 1939], and is similar to the description of auxiliary corpora lutea found in Macaca [Koering, 1969]. More recently, Claver et al [1984a] described the ovary microanatomy of captive black howler monkeys and the most significant feature again was the presence of abundant glandular interstitial tissue in both the cortex and medulla. The presence of these cells has long been recognized in mammalian ovaries.…”

“…The choice of this animal was based on the fact that the genus Alouatta is one of the most difficult New World monkeys to breed and rear in captivity [Claver et al, 1984a;Colillas & Coppo, 1978].…”

Ovarian and Uterine Ultrasonography in Aotus azarai infulatus

“…However, there are few references in the literature related to the ultrasonographic evaluation of ovaries in NHPs, especially Neotropical species. The available studies are related primarily to the macro and microscopic descriptions of the ovaries (Claver et al 1984;Dempsey 1939;Eckstein 1958;Guraya 1968;Hayama et al 1997;Hertig et al 1971Hertig et al , 1976Wislocki 1939). Based on our literature review, our study was the first to evaluate owl monkey ovaries using ultrasound.…”

“…Da mesma forma que nas fêmeas de Alouatta guariba clamitans (bugio marrom) e de Leontopithecus a vagina das fêmeas de S. sciureus apresenta-se como um tubo muscular alongado e achatado dorsoventralmente, fazendo comunicação com o vestíbulo caudalmente e com a cérvix cranialmente, porém, nos Leontopithecus a mucosa vaginal apresenta um pregueamento disposto transversalmente por toda sua extensão, enquanto que tanto nas S. sciureus quanto nas Alouatta guariba clamitans esse pregueamento é mediano longitudinal no qual é possível perceber uma depressão na altura do óstio uretral externo, com diferença entre essas duas espécies de que nas fêmeas de bugio marrom, o óstio uretral externo abre-se em uma papila distinta, proeminente e bilobada, componente não encontrado na vagina das S. sciureus (Claver et al, 1984;Veras et al, 2007;Pissinatti et al, 2008).…”
