I've analyzed another 200 charts (100 boy charts and 100 girl charts) since I last posted. I am keeping track of these charts separately from the 500 I originally looked at since I want to see - once I've looked at another 500 charts - if I get similar results to what I found with the first 500. However, I thought I could still update each of the theories I was testing so people could see how these new charts affected my past findings.
What I found previously for BD on the day of ovulation is that it slightly sways for boys, but the numbers are pretty much the same as chance. Those findings are still the same after looking at another 200 charts.
A majority of all charts - for boys and girls - had BD on the day of ovulation.
- 207 boy charts out of 350 (59.1% of all boy charts had BD on ovulation)
- 192 girl charts out of 350 (54.9% of all girl charts had BD on ovulation)
Out of 399 total charts with BD on the day of ovulation, boys resulted 51.9% of the time (207/399 charts) and girls resulted 48.1% of the time (192/399 charts). While this technically results in more boys, the findings are essentially the same as chance (since the natural birth rate is 51% boys, and 49% girls). It indicates that simply BD on the day of ovulation does not sway.
One thing that does sway a little bit is the kind of cm present on the day of ovulation. If there is ewcm (eggwhite OR watery cm) on the day of ovulation, boys are a little more likely to result.
- 152 boy charts out of 281 charts w/ewcm on ovulation (54.1%)
- 129 girl charts out of 281 charts w/ewcm on ovulation (45.9%)
If there is NOT ewcm present (if it is sticky or creamy, or there is no cm present), girls are a little more likely to result.
- 55 boy charts out of 118 charts with NO ewcm on ovulation (46.6%)
- 63 girl charts out of 118 charts with NO ewcm on ovulation (53.4%)
Still the influence of cm has dropped as I've continued to look at more charts and the results aren't substantially different from chance.
So what does all this mean for swaying? BD on ovulation in no way guarantees a boy, and it doesn't ruin the chances of having a girl. A majority of all charts have BD on ovulation, and simply BD on ovulation results in odds of a particular gender that are essentially the same as chance. Just BD on ovulation in general seems to have little to no impact on the gender that results.
