Part (2)
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 copulation 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).
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.
