在有性繁殖过程中，由于各种因素的影响，雄性进入雌性体内的射精成分会有所不同。对于雄性蜜蜂来说，它们的整个精子都储存在精囊中，直到与雌性蜜蜂第一次交配和随后的射精，之后雄性蜜蜂将死亡。因此，我们可以通过研究体内性器官随年龄的变化来评估与年龄相关的射精改变。这项研究发现，精子从睾丸转移到精囊后，精囊湿重减少，而粘液腺重量没有变化，从而导致精囊中精子密度增加。这表明精囊中精液的减少可能是年龄相关性射精成分改变的潜在原因。
In sexual reproduction, ejaculate components that males transfer into the females vary because of various factors. For male honey bees, the entirety of their sperm is stored in the seminal vesicles until the first copulation with a female and subsequent ejaculation, after which the male will die. Therefore, we can evaluate age-related ejaculate alterations by investigating internal sexual organ changes with age. This study found that seminal vesicle wet weight decreased following sperm transfer from testes to seminal vesicles, while mucus gland weight was unchanged, thus resulting in increased sperm density in the seminal vesicles. This suggests that the decrease of seminal fluid in the seminal vesicles may be the underlying cause for age-related ejaculate component alterations.
