So the key is to know exactly when you ovulate. The Creator has kindly given us a way to find this out by our cervical mucous. Have you ever noticed how it changes in quality over the course of your cycle? You can discern this by getting some mucous on two fingers and pulling them apart (or wipe with toilet paper and then examine that if you prefer). Here's the pattern (starting from right after your period ends):
- Dry
- Wet
- Sticky/Crumbly/Rubbery
- Creamy (Lotiony/Milky)
- Like raw eggwhites (very stretchy, clear) *OVULATION*
- Dry
- Wet (right before menstruation)
It is best to keep track of the difference in cervical mucous throughout your cycle for two or three months and mark the changes in mucous on a calender. You want to know what your track record is, so that when you are ready to try for a boy you can wait to have intercourse until the very end of when your mucous is eggwhite, right before it turns thicker and cloudier. Then you have the highest probability of conceiving a son. For example, if you find, by charting several cycles, that the eggwhite mucous lasts a day and a half, have intercourse near the end of that peak time (but before the mucous changes and gets cloudy).
Other tips for conceiving a boy:
A good idea is for the husband to drink a few cups of strong caffeinated coffee (or tea) 15-30 minutes before having intercourse. This may give extra speed to the male-producing sperm. It is not a good idea to drink caffine on a regular basis, but it may be helpful once a month in this case, until pregnancy is achieved.
Also, experts say that heat kills off sperm--especially the smaller, weaker, male-producing sperm. So it's a good idea for a man not to wear tight clothing, or soak in a hot tub for too long. Even working in front of an oven for a while can cause damage. It doesn't take much heat to decrease sperm production.
For conceiving a girl:
Have sex about five days before ovulation, and then be abstinate until at least three days after ovulation. This allows time for the short-longevity male-producing sperm to die off before the egg is released. The hearty female-producing sperm lives on until the egg is released. It may take several months to conceive by this method, but the likelihood of conceiving a girl when it does take place is much higher.
