The most important factor according to the Shettles Method is the timing of intercourse.
The closer to ovulation that you have intercourse, the higher the likelihood that you will have a boy, since they are the faster of the two types of sperm, therefore likely reach the egg first. If you would like a boy, intercourse should take place during times of peak fertile mucus or no more than 12 hours before ovulation (you can detect ovulation through charting, OPK’s etc). If you chart and have a temperature dip, this is a good time to have intercourse or the following morning. You can also have intercourse for a boy when peak mucus changes into thicker mucus.
The ideal time to have sex for a boy is when the vaginal environment becomes alkaline, which is on the day you ovulate.
Deeper penetration (e.g. doggy-style) is more ideal for a boy, as the male sperm are closer towards the egg, giving them a head start on the female sperm (as well as being further away from the more acidic areas).
For a boy, the woman should try to achieve orgasm either before or at the same time as her partner – or if you are lucky enough, multiple female orgasms can help! The theory on this is that the waves of the orgasm help to draw up the sperm quicker to the egg, again the boys getting a head start on the girls.
For the men – To try for a boy, Shettles suggests men try and keep the scrotal temperature cool – no hot spas / baths, tight clothing or underwear. Boxer shorts are a good alternative. He also recommends no scuba diving, heated vehicles for extended durations or other areas of high heat. A few cups of strong coffee half an hour before intercourse favours a boy.
Shettles claims that his methods for a boy have a success rate of 80-85% and the methods for a girl a little less at 75-80%
