在家蚕雄性生殖器官粗提物中，糖原磷酸化酶只有在去除低分子物质后才能被AMP激活。该酶在雄性生殖道的睾丸、去精管、去精管壶腹、乳腺和精囊中均有活性。射精后乳腺和精囊磷酸化酶活性和比活性明显降低。在这两个腺体的分泌物中，a型酶约占总磷酸化酶活性的80%，但在细胞中则少得多。精子包囊的磷酸化酶活性维持在恒定的高水平，表明该器官发生了细胞外糖酵解。
In crude extracts of the male reproductive organs of the silkmoth, Bombyx mori, glycogen phosphorylase was activated by AMP only after removal of low-molecular substances. This enzyme activity was found in the testis, ductus deferens, ampulla ductus deferentis, and the glandula lacteola and vesicula seminalis in the male reproductive tract. The activities and specific activities of phosphorylase in the glandula lacteola and vesicula seminalis decreased markedly after ejaculation. The type a enzyme comprised about 80% of the total phosphorylase activity in the secretions of these 2 glands, but much less in the cells. Phosphorylase activity in the spermatophore was maintained at a constant high level, suggesting the occurrence of extracellular glycolysis in this organ.
