How To Conceive A Girl

Step 1: Nature's Way

It is important to understand how the sex of a child is decided by nature. All human beings have 46 chromosomes in 23 matching pairs, all of which are present in every cell in our body. The exception to this is the sex cells, sperm, and oocytes or eggs, as these contain only 23 single chromosomes. The 23rd chromosome in all oocytes is always an X chromosome. This way, any egg can become male or female depending on which sperm fertilizes it.
This is because there are two types of sperm produced in equal amounts; one carrying a X chromosome, and one carrying a Y chromosome. If a Y-bearing sperm fertilizes the egg then the baby will be male, and if the X-bearing sperm is the first past the post the baby will be a female.

Step 2: Timing with ovulation

X and Y bearing sperm have different characteristics, with X bearing sperm living for longer than Y bearing sperm. If you want a baby girl you need to be having intercourse several days before ovulation, about 4-5 days roughly.
There are ovulation prediction kits on the market that can help you pinpoint ovulation to within a few hours.

Step 3: Depth of Penetration

When trying to conceive a girl, the depth of penetration should be much shallower, as the environment is more acidic which favours the survival of the X-bearing sperm over the Y-bearing sperm.

Step 4: Dietary Supplement

Although scientifically unproven as yet, it is believed that changes to a woman's diet may influence the eventual gender of a baby at conception.
Calcium and Magnesium supplements should be taken in the months before you plan to have intercourse as this makes the cervical mucus much more favourable to the survival of X-bearing sperm.

Step 5: O+12 Method

Developed by a mother who had produced 6 boys, the O+12 method advocates intercourse to take place 12 hours after ovulation to get a girl. However, it is mostly an anecdotle method with no real scientific basis.
