Why Do I Always Have Boys?
If you’re wondering why you always have boys, today we’ll help you discover some of the determining factors that can explain this predominance.
What determines a baby’s sex?
A baby’s sex is determined by the man’s sperm during conception. The genetic information within the sperm contains the XY gametes, while the eggs of women contain XX gametes.
When they come together, women provide an X chromosome, while men provide either a X or a Y. If it’s an X chromosome, the baby will be a girl, and Y chromosome will result in a boy.
Therefore, your child’s sex depends completely on the sperm, with a 50% chance for each sex.
Why do I always have boys? Is it possible for the male sex to be more prevalent?
If there is a higher percentage of males in your family, you’re not alone. It’s becoming more and more common for families to experience same-sex births, one after another.
The scientific community in general claims this is likely due to sheer coincidence, rather than a genetic tendency.
The damages to a sperm that carries an X gamete that would lead to a baby girl may have to do with a genetic syndrome related to this sex.
This means that the embryos that come from these sperm are weak and end up not surviving.
While this is a condition that is more common among sperm that carry Y chromosomes, it can also occur in those carrying X chromosomes.
At the same time, the damage may occur directly to the X chromosomes because they’re the ones that produce the female embryo, and vice versa.
In other words, there may be an incapacity to produce the type of cell needed for a baby girl.
Physical particularities of the sperm
Some factors like the psychical characteristics of sperm, the lining of the vagina, and a woman’s fertility cycle can influence fertility significantly.
Some believe that masculine sperm are weaker, but also faster, with can favor a quick conception.
While some claim they can use this fact to decide the sex of their future baby with a 70% success rate, this isn’t completely true.
There is no scientific evidence to prove that certain foods, sexual positions, or days within the menstrual cycle have a specific effect on a baby’s sex.
Can certain external techniques predetermine a baby’s sex?
Yes, there are. In some countries, there are laws in place that allow for specific types of assisted fertility treatment. These treatments allow parents to avoid the transmission of certain hereditary illness.
There are two different techniques:
- Sperm selection. This technique allows professionals to choose the sperm that will make up the fertilized masculine or feminine cell. Therefore, they can choose the sex of the fertilized egg – thus avoiding certain genetic diseases linked to a specific sex.
- Pre-implantation analysis. This technique consists of performing in vitro fertilization and then choosing the embryos pertaining to the target sex that don’t possess the genetic illness. Then doctors proceed with implantation in the uterus.
These techniques have helped many parents not only avoid certain genetic conditions, but also choose the sex of their babies. However, these techniques aren’t permitted in every country.
The benefits of having boys
When the time comes to give birth, the most important thing is that your little one is healthy.
In conclusion, while the decision is up to the sperm, there are other possible influencing factors to why some couples always have boys, which are still being researched.It might interest you...
