By prior knowledge we now know that sperms containing the X chromosome are negatively charged while sperms containing the Y chromosome are positively charged. This fact was observed when the sperms were separated by electrophoresis. Numerous studies have revealed that when a weak electrical current was passed through a solution containing spermatozoa, those with the X chromosome were attracted by the anode (+) and those with the Y chromosome by the cathode (-). Some scientists have also identified the appearance of a brief luminous ring at the moment of contact between spermatozoon and ovule. This phenomenon has since been measured and is proof of an electrical involvement in fertilisation. Also the charge on the ovum membrane was not fixed but alternated from positive to neutral and to a negative charge in a cycle. This was called the polarity cycle of the ovum membrane. This polarity was found to be predictable but totally separate from the menstrual cycle. The polarity cycle, which is unknown to most of us, was there in addition to the ovulation/menstrual cycle.

The argument behind this finding is that gender(sex) of the baby is influenced by what scientists call "ionic factors" which generate the charge on the ovum membrane and on the sperms.   First let us view this in a different way---According to the Laws of nature----whatever is happening at the microscopic level is reflected in the happenings at the macroscopic level ---or ---in other words whatever happens at the physical (gross) level is a reflection of what happens at the subtle(cellular) level. So we now come to the most important aspect of man-woman relationship ie. marriage (selection of the partner for mating). Let us now consider the marriage ceremony in various religions: In Christianity---it is the bride who is first asked by the priest "whether she accepts the would-be bridegroom as the lawfully-wedded husband". In Hinduism---it is the bride who first garlands the bridegroom, meaning that she has accepted him as her husband and she will bear his children only. Also it would be worthwhile to note that in Muslim marriage---the would-be bride only is asked by the muslim priest whether she accepts the invitation of marriage(nikah) from her would-be husband. So in man-woman relationship----man is always the proposer and woman is always the chooser---never vice versa.   From the above observation we can say that the proposing rights are a male prerogative and the choosing rights lie exclusively with the female. Just as a woman cannot be impregnated against her wishes---similarly at the micro level---both sperms (x and y having different charge) are attracted to the ovum having a variable charge---but only the sperm which has the opposite charge from that of the ovum will be able to fertilize the ovum and the other sperm will be rejected.   So when the ovum membrane is positively charged, it will attract the sperm carrying X chromosome (which is negatively charged) and a baby girl is produced.  When the ovum membrane is negatively charged, it will attract the sperm carrying the Y chromosome (which is positively charged), and a baby boy is produced. In short, we can say that the 'mating rights' are exclusively with the ovum only-------once the ovum is fertilised then only the x or y sperm determines the sex of the baby(xx means a female and xy means a male)-- --So would it not be most appropriate to say that it is the female which chooses the sex of the baby (by virtue of selecting which sperm to mate with)-------and the male only determines the sex of the baby after conception.(so it is not only unfair but also wrong to blame the male for choosing the sex of the baby---as the poor male has absolutely no control over which sperm(x or y) will finally fertilise the ovum --because it is the mother nature(ovum) who finally decides which sperm(x or y) to mate with in accordance with its polarity------which eventually decides the sex of the baby.   Conclusion: Female of the species are more powerful than the male.
