SEX CHROMOSOMES
It was originally thought that the woman's body was solely responsible for producing either sons or daughters. Of course, over centuries, this perception has caused many women to suffer both physically and emotionally, usually after having daughters because of the importance that many societies place upon sons. However, we now know that it the man's spermatozoa that determine the sex of each child, though some studies still show that a woman's body's biochemical conditions are also a factor in determining which sperm type X or Y reach the ovum first, and therefore the sex of the baby.
To provide a brief overview, when a woman ovulates an egg, it carries an X chromosome. A sperm may carry either an X or Y chromosome. If the sperm with the X chromosome fertilized the egg, the embryo will develop into a girl (XX). If a sperm with a Y chromosome fertilized the egg, then the embryo will develop into a boy (YX).

From the foregoing, if will be seen theoretically that the chances of conceiving a baby boy or a baby girl are 50: 50. In reality, international figures, according to McSweeney (2002) show 51%: 49% (or 106 boys for every 100 girls) but boys have a lower survival rate, which leaves the number at marrying age about equal.
What has been established, however, is that Y chromosome sperm and X chromosome sperm exhibit different attributes and unique qualities. And by understanding the properties and behaviours of each type of sperm, environmental-reproductive contingencies can be manipulated to favour the odds of one type of sperm to fertilize the egg and determine the gender of the baby.
Thus, the possible factors that could influence the success of one gender of sperm over the other to fertilize the woman's egg have become the basis of modern natural sex selection theories and techniques. Undoubtedly, the most popular among these techniques is the Shettles Method, which tries to control a number of variables: timing intercourse in relation to ovulation date, use of sexual position, and depth of male penetration. The logic underlying the Shettles Method is that by changing these three aforementioned factors, X or Y chromosome sperm will be offered a differential advantage in being able to reach, and therefore fertilize the egg.
With the discussion so far on Y and X chromosome sperm, I hope you're able to understand how they combine to develop into either a boy or a girl.
In my next post regarding this topic, in Chapter 3, we will be looking at the peculiar properties of X and Y chromosome sperms in relation to biochemical conditions of women's bodies; those conditions that favours the growth of specific Sperm type against the other.

Thanks for reading, and I hope you will follow me @eurogee for more on this important subject.
And if you find this piece interesting...appreciate by UPVOTING AND RESTEEMING IT

If all men knew this, they would not be chasing their wives away or remarry just because she has all females.Nice work sir and thanks for the help and advice about my post.
You are welcome dear
@eurogee, did i miss out... What a lovely one you got here. why not add the references now so people will be certain and also to prevent plagiarism.... you can alway put your references in every chapter.
Thanks
Okay, I will consider doing that but it will make each chapter really very long and I would not want t people to get overwhelmed reading this piece. However, I will abide by my superiors argument. Thank you
Nice one , my guiders guider
See you eeehhhhhh. Thanks anyways
meep
Very informative. Thanks Boss
Thanks for being my guest
The truth is that most men who had baby girls throughout will easily blame the woman and go for another woman and funny enough the second woman most time gives them a male child. With this, it becomes hard to convince some men the sex of a baby is more determined by the man than a woman.
Nah not really, I've seen dudes marry 3 wives and giving birth to girls only. The truth is, it boils down to a number of factors.
my mama gave birth to 5 boys, no girl.
Yes it do happen to some. All the same sex selection in more dependent on God than man because there sometimes human calculation and arrangement for a particular gives the opposite
Genetically man chromosomal composition determines the Sex of a baby but biochemically, outside man's body, it woman's body's biochemical condition, whether too acidic or too basic/alkaline, is the final determinant as to which of the two sperm types finally makes it to the ovum. So to a large extent, biochemically...according to Shettles hypothesis...women have upper hand. Stay tuned. Thanks
Wao! I love this coz i just got married.
But how and when can we know X or Y chromosome is released and also when is the actual timing for a chance of baby boy during ovulation as some claim that from 3 days before ovulation might produce female while on the ovulation day and till 3 days after might be chance for male child. Thanks.
Survival and speed friend.
Wait on eurogee to post the next one.
Thank you for the response to my friend @maintain4real-eu
Interesting topic. I have learnt some few tips and
would always recommend this to my married
friends.
Yes. It works. I have assisted over 200 people with this work, making my house a mecah kinda
Nice one eurogee, my dad's a doctor and so far, your write up is spot on.
I could state the traits of both x and y chromosome, but I rather not spoil your series.
Yes yes, boss. A good student of biology in secondary would know the properties but it is better it flows with the series for easy understanding.
We should get the older generation on steemit, so they can learn from this informative post. Keep steeming mate!
Thanks you
This is awesome @eurogee. That's a nice read. Keep it up. 👍
Its an honour to have you here @ogoowinner
If you slice a potato in half and the father to be ejaculates on it and you then bury the potato in the ground just as dawn breaks you are guaranteed a boy.
Apparently ;0)
😀This is mode like a tale and have no scientific bases sir. However, it is an honour to have you visit this page. Looking forwards to a stronger collaboration. Followed

Interesting book review. It's like you've taken a book and summarized it so we don't have to actually read it. I have to say though these comments are mind-boggling. I thought it has been basic scientific knowledge since at least the 1900's that the male sperm determines the sex of the baby.
Shettles Method is still a hypothesis and has not been totally accepted but I am a strong supporter of his observations. Because, I have tested it and it's working. Since 2013, I have assisted not less than 200 couples within my locality. The procedure is natural and nothing invasive. You can Google biography of Dr Shettles and find out his many accomplishments. Shettles himself demonstrated this concept; he has 6 children; 3 boys and 3 girls. Lots of success stories bro
Thumbs up
This is so educating. Well done @eurogee
We all needs this post in our family especially new married ones thing for enlighten us
