1) gonadal ontogenesis and differentiation
性腺发生和分化
3) gonadal origin
性腺发生
1.
Histological studies on gonadal origin and differentiation of cultured Acipenser sinensis;
养殖中华鲟性腺发生与分化的组织学研究
4) Gonad differentiation
性腺分化
1.
Gonad differentiation and the effects of temperature on sex determination in the rice frog Rana limnocharis;
泽蛙的性腺分化及温度对性别决定的影响
2.
The origin and migration of the primordial germ cells (PGCs) and the gonad differentiation of loach were studies by light microscope.
通过光学显微镜对泥鳅原始生殖细胞（Ｐｒｉｍｏｒｄｉａｌｇｅｒｍｃｅｌｓ，即ＰＧＣｓ）的发生、迁移和性腺分化进行初步研究，发现泥鳅ＰＧＣｓ最初出现在原肠晚期预定中胚层内，体节中胚层与侧板中胚层分离后而位于侧板中胚层。
5) gonadogenesis
性腺分化
1.
After obtaining larvae of loach by artificial fertilization,the gonadogenesis and differentiation of loaches were studied by light microscope.
从性腺分化开始,将要发育为卵巢的性腺还表现为体积快速增大,向体腔中间靠拢,横截面变宽;而将要发育为精巢的性腺则呈两端尖中间稍突的梭形,增生并不明显。
2.
Obtaining larvae of Paramisgarnus dabryanus by artificial fertilization,the gonadogenesis and differentiation of larvae were studied by light microscope.
从性腺分化开始,将要发育为卵巢的性腺还表现为体积快速增大,向体腔中间靠拢,横截面变宽,而将要发育为精巢的性腺则呈两端尖中间稍突的梭形,增生并不明显,这些特征可能与雌雄性腺的发育和生殖细胞的分化速度有关,可以作为大鳞副泥鳅性腺早期分化的形态特征。
6) glandular differentiation
腺性分化
补充资料：高促性腺激素性性腺功能低下
高促性腺激素性性腺功能低下
系由于卵巢发育不全或功能低下，不能合成和分泌足够的性激素，干扰了对垂体和下丘脑负反馈调节，使促性腺激素分泌增加，导致促卵泡素(FSH)和黄体生成素(LH)水平升高，E2水平低下。此种情况以先天发育异常多见，常表现为性幼稚、如Turner综合征。
