Gynaecology

 * If the infant is male and it looks as though it has no foreskin, she should gently draw the tip of the foreskin forward or even hold it together with a strand of wool to fasten it. For if gradually stretched and continuously drawn forward it easily stretches and assumes its normal length, covers the glans and becomes accustomed to keep the natural good shape.
