Figuring Out Gender Additional Information The Birth Chart Community Q&A The Chinese birth gender chart, an ancient gender prediction method, is a fun way to guess the gender of an unborn child.
To use the chart, you need only two pieces of information — the lunar month and the lunar age of the mother when the baby is conceived.
Greeks were convinced that the (y) sperm is located in the right testis and the x-sperm in the left testis, so Greek men tied their left testis to prevent female’s embryos, but the Indian man held his left testis tightly during intercourse for the same reason. So, we can calculate the time of ovulation and determine the time of intercourse according to the desired sex.
At the same period of time, French men underwent left orchiectomy in order to prevent female embryos production entirely. If intercourse occurs 12 hours prior to ovulation, a baby boy is favored but if it occurs several days before ovulation, it will favor a girl.
Since the eighties the researches are done in order to determine the gender of the baby, which is determined by the type of chromosome in that particular sperm (X-Chromosome) or (Y-Chromosome). This method depends on the molecular Weight of the sperm; researchers found that the y-sperm has a low molecular weight, so it is faster in movement but lives shorter.
At the same time the oocyte only contains X-Chromosome so when fertilization occurs between an x-sperm and an oocyte, the embryo will be a female (xx), while if a Y sperm meets the oocyte then the embryo will be a male (xy). On the other hand, the x-sperm has a heavier weight then slower motion, but lives longer.
The original is allegedly currently in the Institute of Science in Beijing.
Rumors have it that this chart is over 90% accurate when used properly but please remember that this chart is for entertainment purposes only.
