雄性生殖的

Like all Cestoid's each individual has male and female reproductive structures in its proglottid and can reproduce independently.

像所有的绦虫一样，每一条寄生虫的节片上都有雄性和雌性的生殖结构，能够独立生殖。

But in fact, the fellatio is humanity's unlearned behaviour, all female animal when oestrus period, the reproductive organ nearby can secrete the Fellow Mongolia to attract the male gender to be close, and lets the male gender contact the female with the mouth reproductive organ, the amusement period of time, only then starts the copulation.

但事实上，口交是人类的本能行为，所有的雌性动物在发情期时，生殖器附近都会分泌费洛蒙来吸引雄性接近，并让雄性用口去接触雌性的生殖器官，玩乐一阵子，才开始交配。

And both of them spentmore time on sniffing nose, sniffing body, sniffing vulvae of social investigatingbehaviors. 2. Comparation of histology of main reproductive organs between the XO femaleindividuals and the XX female individuals: There were no significant differences incolor of pelage between the XO female individuals and the XX female individuals,and their pelage were gray when they were yong, and weak coffee when they are adult.All of the female mandarin voles had three openings: vulvae, urethra, anus.

在遭遇陌生雄性时，XX雌体和XO雌体都运动了较多的时间，同时也花费了较多的时间接近和攻击雄性，还有花费较多的时间并以较多的频次进行嗅鼻、嗅体、嗅外阴等社会探究行为。2、棕色田鼠XO雌体和XX雌体主要生殖器官的组织学比较：从外形看，XO和XX雌体无毛色差异，年龄较小的时为灰色，较大时时呈现出淡咖啡色。

Objective To investigate the effects of MC-dLR on reproductive system of male rats, and to explore the mechanism.

目的 通过观察微囊藻毒素对雄性大鼠生殖系统的影响，以明确MC-dLR的生殖毒性并分析其作用机制。

Each group comprised 20 rats. Three groups ofdosages (12.5, 50.0, 200.0mg.kg respectively) of H98 were administered by injected into gaster for 9 weeks. The same volume of 0.2%sodium carboxymethyl cellulose was administered to the control groups.

生殖毒性实验方法：将25～35g雄性小鼠按体重随机分为4组，每组20只，按12.5、50.0及200.0mg／kg经口给予H98连续9w，对照组给等容积的0.2％羧甲基纤维素钠溶液；比较各剂量组小鼠生育率及生殖器官的检查结果。

In their new work, the researchers established a genetic connection between male sexuality of an oogamous multicellular green algae species, Pleodorina starrii, and one of the mating types of its isogamous ancestor, the unicellular alga Clamydomonas reinhardtii.

在这项最新研究中，研究人员让一种异配生殖多细胞绿藻（Pleodorina starrii藻）与其同配生殖单细胞祖先（Clamydomonas reinhardtii藻）的其中一种配子类型进行雄性配子结合，从而建立两种藻类的遗传学联系。

In experiment 2, taurine and β-alanine (inhibitor of taurine transportation) were offered to male rats of different ages in water, then the effects of taurine on the reproductive organs index, testis tectology and reproductive hormone were investigated.

试验二通过在饮水中添加牛磺酸和β－丙氨酸探讨了牛磺酸对不同年龄雄性大鼠四种生殖器官指数、睾丸组织形态和四种生殖激素的影响。

Pheromones of conspecific male inse cts are usually belonged to the same type chemical, while the chemical structure s are different. However, male insects can utilize the little difference to attr act female insects, urge the copulating and prevent interspecific mating, etc.

通过不同部位释放的雄性昆虫性信息素种类是多样的，但其化学结构的差异又是细微的，雄性昆虫则利用这些差异来引诱雌性昆虫、促进交配和生殖隔离等。

Methods "Beiao" bait and no "beiao" were selected to evaluate the feeding acceptability of SD rats in laboratory by select fooding method;after putting "beiao" in field for three and six monthes,the results for controlling rats by trap were recorded respectively;rats procreation and rate of infancy and manhood of catching rats from three fields("beiao" bait,Anti Cruor bait and naturalness) were analized by anatomised.

方法实验室采用常规毒饵适口性实验方法观察适口性，现场选择在农田、农户环境，于4次投放毒饵后检查鼠类对贝奥雄性不育剂的消耗水平，用贝奥雄性不育剂处理后3个月和6个月测定鼠密度，解剖观察成年鼠生殖能力，测量成幼年鼠的比例。

Objective To investigate the reproductive toxicity of 3,4-dichloroaniline (3,4-DCA), the effect of 3,4-dichloroanilines on sperms of Wistar rats was studied.

目的 研究3，4-二氯苯胺(3，4-DCA)对雄性大鼠精子的影响，以探讨3，4-DCA对雄性大鼠的生殖毒性作用。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
