Is birth gender entirely random?

Question

Is it? This study seems suggest that vegetarians are more likely to have female babies (http://news.bbc.co.uk/1/hi/health/869696.stm ). Is there any validity to this at all?

Answer 1

Interestingly, I think that the PH balance of the vagina has a lot to do with it. An acidic environment favors girls, since it will kill the weaker male sperm first and leave a greater number of X sperm to fertilize the egg. So, if you are trying for a boy, a good time for intercourse is when the vaginal balance changes to alkaline—on the day you ovulate—otherwise the male sperm will either slow down or die in an acidic environment.
It is thought that minerals in your diet affect the metabolism and environment of the egg and therefore make it more attractive to sperm of one particular sex. If you want a boy, eat plenty of potassium-rich foods such as meat, bananas, apricots, and celery. If you want a girl, lots of magnesium-rich foods such as nuts, soya beans, and leafy green vegetables should do the trick.

Answer 2

the gender is influenced by PH
acid produces females and alkaline males

and there are psycological factors
for example in wartimes ,more males are born
after the wars more females to produce more males again

Similarly , hunger is also a factor , in Nature
the litters of many animals depend on the food supply .like droughts or times of abundance

the excess use of agro chemicals in countries like Mexico ,that are washed of the deforrested lands into the rivers and end up in drinkwater supplies ,greatly affect sexuality,many boys are born gay or infertile
