The children lines tradition appears in palmistry texts from multiple cultures and centuries. The basic claim is that vertical lines on the percussion edge of the hand — the outer edge, below the Mercury finger — indicate children. More lines, more children. Deep lines, healthy children. Faint lines, difficult pregnancies or no children at all.
This is not biology. Fertility is determined by hormonal profiles, reproductive anatomy, sperm quality, age, underlying health conditions, and a wide range of other medically understood factors. None of these have any known relationship to skin creases on the outer edge of a hand.
The reason this claim demands special attention is context. People who ask about palmistry and fertility are often people who are struggling to conceive or who are anxious about whether they will be able to. A careless reading can cause immense distress, false hope, or — perhaps worst — a delay in seeking actual medical help.
