While in countries like the UK, scientific methods of sex are only legal for medical purpose, you can still try some natural methods.

Timing sex is one of the most popular methods. If you want a boy, do not have sex for 2-3 days before ovulation, then have intercourse as soon as possible so that the speedier male sperm (i.e. The sperm with Y chromosome) can reach the egg first. If you want a girl, have sex 2-3 days before ovulation, so that the male sperm will have died by the time the egg is released.

While female sperm prefer an acidic environment, mail sperm prefer an alkaline environment, so you can make your vagina more acid or more alkaline to influence the sex of your baby. If you want a boy, you can flush your vagina with a solution of bicarbonate of soda 30 mins before sex. If you want a girl, then flush with diluted lemon juice.

It is also said that diet can affect the sex of a baby as well. If you want a boy, eat more foods that are contain rich sodium and potassium, e.g. Rice, pasta, potatoes, beans, mean, salted fish, celery, banana, apricots… If you want a girl, you can eat food that rich in magnesium and calcium, e.g. Eggs, nuts, soya beans, fresh fruit juice, daily products, and leafy green vegetables.
