I think most of us know to stay away from vaginal lubricants when trying to conceive. However, the study cited below shows that there are some sperm friendly vaginal lubricants including cannola oil (skip the vinegar!) Read more:
Vaginal lubricants for the infertile couple: effect on sperm activity.
From the study:
MAIN OUTCOME MEASURES: Sperm motility was evaluated by manual motility counts and by computer-assisted semen analysis. Sperm viability was evaluated with Hoechst 33258 dye. The effects of the various lubricants were compared with those of a spermicidal agent, Gynol II (negative control) and Ham's F-10 (positive control). RESULTS: Commercial lubricants inhibited sperm motility by 60-100% after 60 minutes of incubation. Sperm exposed to Replens or Astroglide were nonmotile and nonviable after incubation for 60 minutes, similar to the control, nonoxynol-9 containing product Gynol II. Canola oil had no detrimental effects and was indistinguishable from Ham's F-10 in terms of sperm viability and motility.
