TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['To evaluate the effect of NG-monomethyl-L-arginine (L-NMMA) on sperm motility.', 'Controlled study using motile sperm suspensions obtained by the swim-up technique.', 'Endocrine Laboratory, Department of Obstetrics and Gynaecology, University College London Medical School.', 'Men attending the Reproductive Medicine Unit at University College London Hospitals, Obstetric Hospital, for routine fertility investigations.', 'Motile sperm suspensions were incubated with either culture medium (control) or L-NMMA (test) for 24 hours at 37 degrees C.', 'Motion characteristics were assessed manually and by computer-assisted sperm motility analyzer.', 'In all 23 preparations either equivalent or significantly higher percentage total motility and percentage rapidly motile sperm were observed in the test compared with the control samples at 24 hours. There were no significant differences in motion characteristics between test and control specimens at 6 hours.'] Does nitric oxide synthase inhibitor NG-monomethyl-L-arginine preserve sperm motility after swim-up?
OUTPUT:

agent
yes
