The Father Determines The Sex Of His Baby

Every day, women are blamed, mocked, and even threatened for “failing” to produce a male child.
Some men cheat.
Some marry second or third wives.
Some emotionally abuse their partners.
Some families go as far as calling a woman “incomplete” because she births only girls.
All of this rests on one thing:
Ignorance.
Pure, loud, stubborn ignorance.
Let’s break this myth with basic science everyone should know.

1. The Biology of Sex Determination: Simple and Clear
Humans have two sex chromosomes:
· Females = XX
· Males = XY
This means:
✔ The woman can only contribute X
The baby’s sex depends ENTIRELY on which chromosome the father gives.
If the man gives X → XX = girl
If the man gives Y → XY = boy
This is not opinion.
This is not culture.
This is not tradition.
This is biology.
2. So Why Are Women Blamed for Gender?
Because culture has been louder than science.
For centuries, societies placed value on male children because of:
· Inheritance
· Family name
· cultural roles
· Patriarchy
· Misunderstanding of biology
Women were punished for something they have absolutely no control over.
But today, with education and access to information, there is no excuse.
A man determines the baby’s sex — end of argument.

3. Even Educated Men Still Believe the Myth
Shockingly, some men in:
· Healthcare
· Science
· Academia
· Public health
· educated professions
still insist the woman is responsible.
This shows that education is not the same as awareness. You can have degrees and still carry ignorance in your heart.
4. Why Boys and Girls Happen Randomly
Inside a man’s body:
· Half of his sperm carry X
· Half carry Y
That means every pregnancy is a 50/50 chance — like tossing a coin.
If a man fathers only girls, it only means:
· His X-sperm fertilised the egg each time
· Not that the woman “failed”
If he fathers only boys, it means:
· His Y-sperm fertilised the egg
The woman is never the cause.

5. Why Some Men Still Desire Male Children
Reasons vary:
· Cultural pressure
· Family expectations
· Desire for lineage
· Misplaced masculinity
· Social conditioning
But none of these justify:
· Cheating
· Abuse
· Threats
· Emotional punishment
· Divorce
· Taking second wives
No woman should suffer for biology she cannot control.
6. If You Want a Male Child, The Responsibility Is Still Yours — NOT HERS
If a man genuinely prefers a male child:
✔ It is HIS sperm (X or Y)
✔ HIS genetics
✔ HIS contribution
The woman cannot:
· change her X chromosome
· influence whether the man releases X or Y sperm
· force nature to produce a boy
She is being blamed for something she did not choose and cannot change.

7. Let’s Stop the Violence and Stigma
Blaming women for the baby’s sex leads to:
· emotional trauma
· depression
· marital breakdown
· domestic abuse
· polygamy
· abandonment
· unnecessary suffering
All built on a scientific lie.
We must stop normalizing ignorance.
8. Final Message to Men
· YOU determine the sex of the baby.
· YOU are responsible for X or Y.
· YOU are the one who gives a girl or a boy.
So blaming your wife isn’t just unfair. It is scientifically wrong.
Respect women.
Respect science.
Stop the blame.
