A spermatophore or sperm ampulla is a capsule or mass created by males of various animal species, containing spermatozoa and transferred in entirety to the female's ovipore during copulation. It may contain nourishment for the female, in which case it is called a nuptial gift, although in many species the "gift" provides little nutrient value (one group in which it usually is nutritious are the bush crickets).
例句与用法
1.
As we know , there are a pair of duct - like gland tissue located in the back of urethra and prostate , that is spermatophore 我们知道，在人体的后尿道处，前列腺的后方，生长着一对呈管状的腺体组织，叫做精囊。
2.
And the prostate is close and relatively to spermatophore and ejaculation tube , prostatitis also causes inflammation of spermatophore sometimes 前列腺与精囊和射精管毗邻并密切相关,因此前列腺炎往往会同时累及精囊。
3.
This gland is located on the distal end of spermatophore cyst , and shaped like a semicylinder which consists of many acini 促雄性腺位于精荚囊末端，半圆柱状，由许多腺泡组成，细胞内富含粗面内质网和高尔基氏体，推测其分泌蛋白质性质的激素。
4.
Since the spermatophore is close to the prostate , the two organs will interact like brothers . that means vesiculitis and chronic prostatitits often occur together 由于精囊与前列腺在解剖上紧密的毗邻关系，这两个器官在发炎时常是一对难兄难弟，即精囊炎往往与慢性前列腺炎合并发生。
5.
The secretion of the spermatophore is mainly one of components of semen , the secretion is dyed by the spermatophore bleeding and released from body , bloody semen occurs during ejaculation 精囊腺的分泌液是精液的主要成分之一，精囊出血使其分泌液染上血迹，当随着精液排出体外时，就发生了血精。
6.
Prostate gland tissue can transport the secretions from the spermatophore and the spermaduct by the conduit , when ejaculate the prostate and spermatophore and muscles contract , and push out the secretions into the nearly urethra from gland dunk and gland duct 前列腺组织可以将精囊和输精管中的内容物经管道输入尿道。射精时前列腺和精囊和肌肉收缩，将分泌物从腺泡及腺管中压入近端尿道。
7.
Now it has been one of the most important aquatic products in the freshwater cultivation . however , this prawn ca n ' t survive at a water temperature lower than 14c , which has seriously limited its cultivation expanding . in order to obta in a new breed of this prawn with increased cold - resistance , we investigated the cloning of a synthetic gene ( sbwafp ) based on the primary sequence of the mature spruce budworm ( choristoneura fumiferana ) antifreeze protein ( sbwafp ) and the integration of sbwafp into the embryo genomes of giant freshwater prawn by spermatophore - microinjection ( smi ) , a sperm - mediated gene transfer technique 本研究的特色和创新之处在于，针对罗氏沼虾不耐低温，但体型相对较大，精荚明显的特点，首次将目前已知具有最强抗冻活性的云杉卷叶蛾( sprucebudworm ， choristoneurafumiferana )抗冻蛋白( sbwafp )基因( sbwafp ) ，通过精子介导的转基因技术整合到罗氏沼虾的胚胎中，以期培育出耐低温的罗氏沼虾新品系。
