How to Have a Boy or Girl Through Scientific Methods

Many couples, or even singles who want to get pregnant,  would love to have control over the gender of the child they bear at any given time rather than leaving it to nature. Fortunately, there is sufficient scientific knowledge that can be used to increase the odds of having a specific gender.

It does not take a genius to learn how to have a girl through scientific methods or natural conception and gender selection.

In fact, there are various approaches that are recommended for those looking up information on how to have a girl or how to have a boy.

Here is a brief look at how you can conceive a girl child through scientific interventions.

The biology of sperm cells

The gender of a child depends primarily on the father’s sperm cells which can be male or female.

Male sperm cells carry Y-chromosomes and are said to swim very fast, have a low resilience and die fast (within 2-3 days of ejaculation).

spermFemale sperm cells on the other hand contain X-chromosomes and are said to be slightly larger (carrying 2.8% more DNA) than male cells. They are more resilient (taking up to 5 days) and swim a lot slower.

This is the single most important characteristic of sperm cells that is used as foundation in most information regarding gender selection.

As a matter of fact, it is the same used when looking to boost your chances of conceiving a boy as well.

Scientific ways of conceiving a girl

As aforementioned, male sperm cells contain Y-chromosomes and will result in the conception of a boy child if they fertilize the egg.

Similarly, female sperm cells containing the X-chromosomes will result in the conception of a girl child. In order to scientifically intervene in the conception of a child, the male and female sperm cells need to be separated.

There are two main methods used:

a) Ericsson Technique

– this technique relies on the swim speed of sperm cells. Since male cells swim
faster than female, a special sorting technique is used to isolate them based
on their swim speed.

Once done, the same kind is used in artificial

b) Micro-sorting

– this is another popular technique used in separating male sperm cells from
female cells. It is based on the fact that female sperm cells are slightly
large in diameter than male sperm cells as they contain more DNA.

A dye is applied to the sperm cells and large female cells are expected to absorb more of the dye.

These two techniques enjoy a high success rate, but are not a guarantee that you will get a girl. In both cases, you have a 9 out of 10 chance of getting a girl and 3 out of 4 for a boy.

conceive a boy or girl


There are various recommendations for those who want to learn how to have a girl using natural means.

These include timing ovulation, increasing intake of certain nutrients, shallow penetration ejaculation and having intercourse 4-5 days before menses among others.

Compared with these methods, scientific options offer the best solution if you want to be at least 90% sure. It simply uses rigid science that can be used to isolate the female sperm cells and use them to fertilize the egg.
