Concept
The Shettles Method is a child conception idea that is reputed to help determine a baby's sex, developed by Landrum B. Shettles in the 1960s.
By following the various methods outlined by Dr. Shettles in the book "How to Choose the Sex of Your Baby" it is proposed that a couple can determine whether they will have a boy or a girl. Proponents claim between 75 and 90 percent effectiveness, but experts do not agree that the method works.
According to the theory ,male (Y) sperm are faster but more fragile than female (X) sperm. The Shettles method aims to exploit the longevity factor, as opposed to the Ericsson method where the semen is deposited outside the woman and time is given for the fast/slow swimmers to separate before artificial insemination.
Timing of Intercourse
In order to have a boy insemination should occur as close as possible to the moment of ovulation so that the faster, Y-sperm arrive first and achieve ovulation, according to the theory. When seeking a girl insemination the couple should seek to have sex 2½ to 3 days before ovulation.
Sexual Position
Shallow penetration coupled with the sperm deposited close to the entrance favors female conception because the area is more acidic, which inhibits the weaker Y sperm, according to the theory
Orgasms
Orgasms favor male sperm because they make the vaginal environment more alkaline. Acidic environments harm Y sperm, according to the theory, making conception of a girl more likely.
