本文是一个说明性的指南,间性的蟑螂Rutilus rutilus,基于150个个体。大多数间性蟑螂的雌性生殖细胞或卵母细胞,主要是男性性腺(睾丸),和/或畸形/间性生殖管道。雌雄间性鱼类睾丸组织中卵母细胞的数量、形态和发育阶段差异很大。在大多数间性鱼,少数初级卵母细胞,或众多的初级和次级卵母细胞,随机分散在整个睾丸组织(多灶性间性)。在其他更严重的女性化个体中,大面积的卵巢组织与睾丸组织明显分离(局灶性间性)。几乎所有的中间性个体都有一个类似雌性的生殖管(卵巢腔)。在轻度的中间性病例中(大多数生殖细胞为雄性),卵巢腔与雄性精子管/输精管一起存在,而在某些严重病例中,精子管缺失或退化。(C)2001年,不列颠群岛渔业协会。
This paper is an illustrative guide to intersex in the roach Rutilus rutilus, based on 150 intersex individuals. Most intersex roach had female germ cells, or oocytes, within a predominantly male gonad (testis), and/or malformed/intersex reproductive ducts. The number, pattern and developmental stage of oocytes within testicular tissue in intersex fish varied greatly. In most intersex fish, a few primary oocytes, or numerous primary and secondary oocytes, were scattered randomly throughout the testicular tissue (multifocal intersex). In other, more severely feminized individuals, large areas of ovarian tissue were separated clearly from testicular tissue (focal intersex). Almost all intersex individuals had a female-like reproductive duct (ovarian cavity). In mild cases of intersex (in which the majority of the germ cells were male) the ovarian cavity was present together with the male sperm duct/vas deferens, whilst in certain severe cases, the sperm duct was absent or vestigial.
