The Presence of a Motility Inhibitor Within Spermatozoa May Explain the Poor Sperm Motility of Some Infertile Men is a research paper published in Journal of Andrology (1986). On theSindex it has a DataRank of 1.5. It has been cited 23 times, with 13 citing works in its 1-hop citation network. Its calibrated FAIR score is 49/100.
The presence of motility inhibitors in seminal plasma and within spermatozoa from control and infertile men with poor sperm motility was investigated using demembranated reactivated human spermatozoa. No difference was found in the inhibitory capacities in seminal plasma of patients with poor sperm motility (< 50%) when compared with that of fertile controls with motility above 50%. No correlation was observed between inhibitory capacity and sperm motility. However, when extracts of spermatozoa from these patients were tested for the presence of inhibitor, it was observed that three of nine patients had an inhibitor in their sperm extract. By contrast, all sperm extracts from fertile control subjects were devoid of inhibitor. It was concluded that the presence of a motility inhibitor in seminal plasma does not explain the poor sperm motility observed in patients. The presence of a motility inhibitor within spermatozoa, however, may represent an important factor in the etiology of the poor sperm motility observed in some patients.

From 12 citing papers with measurable signal
Ranked by citation count — the same ordering the engine uses when summing log1p(Cq) over citers.
DataRank blends this paper's own citation count with the influence of the papers that cite it. Here, roughly 31% comes from its base citations and 69% from the citation network (12 citing papers contributed measurable signal).
Citers are pulled from OpenAlex sorted by cited_by_count:descand capped per paper, so when the cap binds we keep the highest-signal references and the score is reproducible across reruns.
