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. The nearer to the entry to your vagina, the greater amount of acid the females’s tract is. Additionally, deep penetration puts the sperm closer towards the egg, and provides those aggressive boy sperms a head begin. Therefore, a superficial penetration will prefer girls – and much deeper will prefer males. Shettles advises the missionary-position for a woman, and rear-entry (doggy-style) for the child.
