Dr Shettles, the pioneer of natural gender selection recommends assuming different sexual positions for the conception of a boy, or girl. According to his theory, male sperm are faster but more fragile than female sperm. In addition, acidic environments harm Y sperm, making conception of a girl more likely. The Shettles method aims to exploit these two factors.
To conceive a girl, it is best to assume the “missionary position’. This is the face-to-face position with the male on top. Missionary position prevents the sperm from direct deposition near the opening of the cervix, where the secretions are most alkaline and favors the male-producing sperm. Shallow penetration at the time of ejaculation will further help ensure that the sperm passes through the vaginal wall, where secretions are naturally more acidic and therefore favor the female-producing sperm.
Summary: To conceive a girl, try shallow penetration and missionary position.
