| 摘 要： | 黄鳝由雌转雄性时,其生殖腺滤泡细胞变得肥大和充满分泌物,卵母细胞的微绒毛、线粒体与放射带退化,卵黄液化。滤泡细胞吞噬卵黄颗粒并消化吸收后,最后形成类胡罗卜素瘤。随着卵巢的退化,精细胞与精巢逐渐形成。

| Abstract: | This paper reports histological and ultrastructural changes in the gonad during sex reversal from female to male in Monopterus albus. During the sex reversal the follicle cells became hypertrophic and were filled with secreta. The microvilli, zona radiata, and mitochondria of the oocytes degenerated. The yolk spheres were liquefied. After the yolk granules were digested and absorbed by hypertrophic follicle ceils, a round nodule with orange-coloured substance was finally formed. With the degeneration of the ovary, the spermatids and the testis were gradually formed. |
