Are you expecting a baby and have a little desire in the back of your mind, "I want a son" or "I'd rather have a daughter"? This is a very common feeling for many people. So at a time like this, your grandmother, mother-in-law, or even someone you meet at the clinic will probably tell you various "secret methods", right? You must have heard a lot of stories like "If you want a son, do this", "If you want a daughter, be that". So today, let's talk about whether these methods are really scientifically successful, and what is the truth in them.
Can you change the sex of a baby through food and drink?
A recent study found that mothers who eat a good breakfast, especially breakfast cereal and foods high in potassium (like bananas), are more likely to have sons. The study also found that mothers who skip breakfast and eat fewer calories per day are more likely to have daughters.
But here we need to understand something very important . This only indicates an association between the dietary patterns of mothers who had sons. That is, a cause-and-effect relationship has not yet been proven that eating these foods led to the birth of a son.
Think about it this way. Even among animals, we see patterns like this. Animals that are well-fed and strong tend to have males, and animals that are less well-fed tend to have females . This may be an evolutionary thing. But in humans, there is no scientific evidence to say for sure that "if you eat this, you will definitely have a son" or "if you eat this, you will definitely have a daughter."
What are other methods that come from the past? (Low-Tech Methods)
Aside from food and drink, there are many other ways to communicate, whether online or in person. These are often beliefs that have been passed down from generation to generation. Let's look at a few of them.
| Method | The supposed reason for that |
|---|---|
| Timing of contact | If you want a son, contact as close as possible to the day of ovulation. If you want a girl, contact a few days before ovulation. The reason for this is the belief that the male sperm (Y chromosome) moves faster but has a shorter life span, and the female sperm (X chromosome) moves slower but has a longer life span. |
| Vaginal pH | Some suggest douching with a mixture of vinegar and water to help a daughter's vagina become acidic, and douching with baking soda and water to help a son's vagina become alkaline. |
| Sexual Positions | There is a belief that certain positions help in conceiving a girl, while others help in conceiving a boy. |
What do doctors say about these methods?
If you ask an obstetrician and gynecologist about this, most of them will say that there is no scientific basis for any of these methods.
"To be honest, there is no proven old-fashioned method anywhere that can determine the sex of the baby. It's all just random events," reproductive health experts point out.
Simply put, when a child is conceived, the father's sperm determines whether it will be a boy or a girl. There are two types of sperm, the X chromosome and the Y chromosome. The mother's egg always carries an X chromosome.
- If an X sperm unites with an egg , a girl (XX) will be produced.
- If a Y sperm unites with an egg , a boy (XY) is produced.
This is completely 50-50. It's like flipping a coin and getting heads or tails. If you follow a certain method and have a baby of the gender you want, it's not because you used that method, it's because you had that 50% chance. In medicine, we call these "anecdotes," which are personal experiences, not scientific evidence.
Are there any risks in using these methods?
This is also a very important issue. While some methods are harmless, some of them can cause side effects.
- Diet : Consuming too many calories while expecting a boy can lead to unnecessary weight gain. Also, restricting food intake, especially reducing nutrients while expecting a girl , is not good for a woman who is planning to get pregnant. The mother needs to get the nutrition she needs for a healthy pregnancy.
- Timing of intercourse: If you can't accurately predict your ovulation day, you may end up having sex on the wrong days. This can further reduce your chances of getting pregnant . On average, even a healthy couple has a 20% chance of getting pregnant in a given month. So there's no point in reducing that further.
- Douching: Douching the vagina with things like vinegar or baking soda is never recommended. These can kill the natural protective bacteria in the vagina, cause infections, and damage sperm.
So, some doctors say that if you try a harmless method (like a small change in diet) and it gives you mental pleasure, it's okay, but don't expect 100% results. But, the most important thing is a healthy baby and a healthy mother. Therefore, before trying such methods, be sure to talk to your doctor and get advice.
Take-Home Message
- Having a son or a daughter is naturally determined by a 50-50 chance. There is no scientifically proven way to change this.
- Methods such as diet and timing of sexual intercourse are based on personal experience and weak evidence, not on solid scientific proof.
- Methods like douching can be harmful to your health, so avoid them completely.
- Your biggest goal should be a healthy pregnancy and a healthy baby. So, rather than worrying about the baby's gender, focus on a balanced diet, exercise, and mental well-being.
- Whenever you are expecting a baby, talk openly with your doctor about your concerns and hopes.
