The pH for the ladies’ tract can be essential.
A far more environment that is acidic girls, because it will kill the weaker y-sperms first, making a greater volume of x-sperms open to fertilize the egg. A more alkaline environment favors boys on the other hand. Shettles advises a douche of vinegar and water(acid) instantly before sexual intercourse to prefer a lady; a douche of water and baking soft drink (alkaline) can help for the kid. (do not test this without reading Shettles! You need to dilute the douches correctly, relating to their formula, or they will not assist and may harm you.)
Note: Some ladies are obviously very acid and now have a difficult time conceiving guys.
Position of depth and intercourse of penetration are very important, partly as a result of pH.
