插入去

插入去（學名：_ aedeagus _）， 閣名拍尾仔、中葉突，陽莖器等，是雄性的肢動物 ( 主要是蟲豸）的生殖器，佮母的動物交配的時陣通過插入去器來分泌由𡳞核丸產生的精子。這个器官會當類似著乳類動物的陰莖，就算講插入器的構造其實閣較複雜。部份蟲豸的插入器有莢包裹，就敢若𡳞脬的包皮按呢，但無叫「𡳞鳥」，是叫做「陽莖」。

語源

「 插入去」的學名「_ aedeagus _」是古希臘語的 η αιδώς（_ aidos _）抑是 το αιδοίον（_ aidoion _）、 眾數作 τα αιδοία（_ aidoia _）。

改破構造

插入去是雄性蟲豸腹肚的一部份，即其規身體三个主要部份的上尾仔的部份。插入去器有生殖管連接對其體內的一對𡳞核丸。插入器是雄性蟲豸的陽莖的部份，其構造複雜，而且無仝款的種間會有無仝款的排列方式。 complex and often species-specific arrangement of more or less sclerotized ( hardened ) flaps and hooks which also includes in some species the valvae ( clasper ) , which are paired organs which help the male hold on to the female during copulation . During copulation , the aedeagus connects with the ovipore of a female . The aedeagus can be quite pronounced or _ de minimis _ .

The base of the aedeagus may be the partially sclerotized phallotheca , also called the phallosoma or theca . In some species the phallotheca contains a space , called the endosoma ( internal holding pouch ) , into which the tip end of the aedeagus may be withdrawn ( retracted ) . The vas deferens is sometimes drawn into ( folded into ) the phallotheca together with a seminal vesicle .

節肢動物的精子往母蟲放送的時陣袂以液態 with free-swimming spermatozoa 傳送，是啊 contains capsules called spermatophores in which the actual spermatozoa are enclosed . In addition to the spermatophores , in some species the aedeagus also discharges a spermatophylax , a ball of   精弓 nutritious secretions to aid the female in producing offspring .

鱗翅目的大多數雄性物種，其插入器平均有鞘， which is supported by an organ called the juxta , which is located between the aforementioned valvae .
