There are some things you need to keep in mind when using lubricants if you want to get pregnant. Most products are actually adjusted to the pH value in the infertile phase of the cycle. Then the pH value of a healthy vaginal mucosa is between 3.5 and 5.5. However, it is too acidic for sperm, they are more active at a value between 7.2 and 8.5. The use of most lubricating gels therefore limits the mobility of spermatozoa and thus minimizes the chances of fertilization.
For couples wishing to have children, there are therefore lubricants adapted to the pH of the vaginal mucosa in the fertile phase. There is also a gel among the 20 products tested: Beimexperts measure a slightly alkaline and therefore sperm-friendly pH value of 7.8.
