Cyclic adenosine 3':5'-monophosphate (cyclic AMP) levels were determined in 103 samples of human semen and grouped according to the number of spermatozoa in the ejaculate. No correlation was found between cyclic AMP concentrations and the number, motility, and morphology of the spermatozoa or the fructose content, pH, and volume of the ejaculate. Similar findings were obtained with cyclic guanosine 3':5'-monophosphate levels in 24 samples of human semen. Therefore, cyclic nucleotide levels in human semen appear to be derived from sources other than spermatozoal adenylyl or guanylyl cyclase.
测定了103份人类精液样本中的环磷酸腺苷（cAMP）水平，并根据射精中的精子数量进行分组。未发现环磷酸腺苷浓度与精子数量、活力、形态或射精中的果糖含量、pH值和体积之间存在相关性。在24份人类精液样本中，环磷酸鸟苷水平也得到了类似的结果。因此，人类精液中的环核苷酸水平似乎来源于精子腺苷酸环化酶或鸟苷酸环化酶以外的其他来源。
