The objective of this study was to characterize and estimate the population of ovarian preantral follicles in juvenile six-banded armadillos. Pairs of ovaries from five armadillos were collected during a routine epidemiological survey of leprosis (three healthy and two infected females). Ovaries weighed approximately 0.06 kg, representing a gonadosomatic index of 6.9 ± 0.8%. The mean ovarian follicular population was 15,567.2 preantral follicles per ovarian pair. For most females, follicular population was mainly composed of primordial follicles. No major histological ovarian parameter was affected by infection. All females presented high rates of follicular degeneration, regardless of infection. In conclusion, we present original particularities regarding the qualitative and quantitative characteristics of the ovarian population of juvenile six-banded armadillos.
本研究的目的是对幼年六带犰狳的卵巢窦前卵泡群体进行特征描述和估计。在一项关于麻风病的常规流行病学调查期间，收集了五只犰狳的成对卵巢（三只健康雌性和两只感染雌性）。卵巢重量约为0.06千克，性腺体指数为6.9±0.8%。每对卵巢的平均卵泡群体为15,567.2个窦前卵泡。对于大多数雌性而言，卵泡群体主要由原始卵泡组成。感染未影响任何主要的卵巢组织学参数。无论是否感染，所有雌性的卵泡退化率都很高。总之，我们展示了幼年六带犰狳卵巢群体在定性和定量特征方面的原始特性。
