One of the best tips to conceive a boy is related to the timing of intercourse. When you want to have a son it's important to plan lovemaking to as close as possible to ovulation. The reason you want to do this is because the male sperm swim faster than their female counterparts. If you are unsure of when you will be ovulating, you can either pick up an ovulation kit at a local pharmacy or use a thermometer to test your basal temperature each day.
What the man drinks before lovemaking may actually impact the gender of the baby. One of the tips to conceive a boy that many people believe strongly in has to do with coffee or cola. If the man drinks a caffeinated beverage before conception this will make the male sperm more energetic which will result in them reaching and fertilizing the egg first. Many people would classify this as an old wives' tale, but it's certainly worth a try if you have your heart set on a son.
