\nUse of personal lubricants is not recommended for couples that are trying to conceive based on several studies reporting their deleterious effect on sperm motility. In spite of this, 43% of all trying-to-conceive couples use personal lubricant products due to a high frequency of vaginal dryness. The current study was designed to compare in vitro fertilization and embryo development of bovine oocytes in the presence of moderate doses (10%) of several different products. In vitro matured cow oocytes were fertilized by bull sperm with: 10% KY Jelly\u00ae; 10% FemGlide\u00ae (labeled as “sperm compatible”); 10% Pre~Seed\u00ae (a new moisturizer developed to provide an optimal sperm environment); and control TALP IVF media. Lubricants were only present during the fertilization incubation of sperm and oocytes. The bovine IVF model allows for detection of sperm DNA damage which can inhibit embryo development. Embryos were cultured for 7 days and then scored for normal development for blastocyst (multi-cell) stage. Data are expressed as Mean (SEM).Treatment.<\/p>\n\n\n\n\n\n\n\n

\n<\/span>KY Jelly\u00ae in the fertilization medium had a very negative effect on fertilization and development (a,c differ by p<0.001), with only 2% of all eggs developing to the blastocyst stage. FemGlide\u00ae decreased embryo development as compared to the Pre~Seed\u00ae treated sperm (b,c differ by p=0.05). Pre~Seed\u00ae did not effect embryo development as compared to the control media in this model, in fact a trend for improved development was seen. Mouse embryo development studies with 10% volume of test product are routinely done as a toxicology screen for assisted reproduction media. A similar design, using cow embryos detected a harmful effect of KY Jelly\u00ae and FemGlide\u00ae on embryo development after sperm exposure to these products.\u00a0<\/span><\/p>\n
