Will Durex lube interfere in trying to conceive?
Yes it could….Some lube even saliva can kill sperm and decrease your chances of conceiving….Preseed is the best lube to use while TTC Why do lubricants harm sperm? The best pH value for sperm migration and survival in cervical mucus has been established by the World Health Organization at between 7.0 and 8.5. This coincides with the normal rise in pH of cervical mucus found in women at the time of ovulation. In contrast, vaginal lubricants tend to have pH values below 7, and often as much as half of this value. These pH values can cause sperm death. Sperm are also sensitive to both high and low osmolality (concentration of osmotically active particles in solution) because these can cause the cells to either shrink or swell too much. A physiologic osmolality around 320 mOsm/kg (that of semen) is best for sperm function. Sperm motility decreases with exposure to increasing osmolality, with all motion stopping at 600 mOsm or greater. Lubricants have osmolality levels 3-10 times that o
