Background:

Man’s sperm consists of X & Y spermatozoa. X spermatozoa decides the female whereas Y is the male.Referring to these physiological properties of the spermatozoa, gynecologists set up the theory of “Choice of Baby Girl or Boy”.

1st Factor : Food

If you want a baby girl : Husband must eat more alkaline food, wife eats more acidic food.

If you want a baby boy: Husband eats more acidic food, wife eats more alkaline food. Alkaline Food = vegetables, fruits, egg white, milk, algae, etc.Acidic Food = Meat, seafood, etc.

2nd Factor : Timing (When to do it?)

If you want a baby girl : Frequent copultaion during pre-ovulation period.

If you want a baby boy: Copulating just before ovulation or just after ovulation.

How to confirm ovulation period? Body temperature increases (you may want to use SPC chart to monitor your body temperature here. Surf to find what is SPC chart).

3rd Factor : Penetration (How to do it)

If you want a baby girl: Husband to avoid deep penetration in the female vagina during copulation. If you want a baby boy : Deep penetration by the husband is suggested.

Reasoning: Characteristics of X & Y spermatozoa: X : Marathon runner with good stamina Y : Sprinter but poor stamina
So, with deep penetration, the chances for Y to reach destination will be higher.

4th Factor : Stimulation

If you want a baby girl: Wife should avoid stimulation during copulation. Secretion from female vagina becomes alkaline when stimulated, therefore this promotes the activity of Y spermatozoa.

If you want a baby boy: Husband ejaculates after wife has been stimulated.

5th Factor : Wife’s Preparation

If you want a baby girl : Rinse the vagina with solution dissolving 2 spponfuls of white vinegar in 1 liter of water. Since an acidic condition decreases activity of spermatozoon. If you want a baby boy: Rinse the vagina with solution dissolving 2 spoonfuls of soda in 1 liter of water.

6th Factor : PositioningIf you want a baby girl : Female to be on the top position & male to be on the bottom position. If you want a baby boy: Male to be on the top position & female to be on the bottom position.This posture allows the Y spermatozoon to reach the destination faster.
