Determining the sex of a baby can be done through various methods, but it's important to understand that these are scientific procedures and not mere calculations. Here are a few commonly used methods:
- Ultrasound Scan: This is the most common and reliable method. At around 20 weeks of pregnancy, a detailed ultrasound scan can usually identify the baby's sex by observing the external genitalia.
- Non-Invasive Prenatal Testing (NIPT): This blood test, typically done around 10 weeks of pregnancy, analyzes fetal DNA in the mother's blood. It can determine the baby's sex, but it's primarily used to screen for chromosomal abnormalities.
- Amniocentesis and Chorionic Villus Sampling (CVS): These are invasive procedures used for genetic testing. While they can determine the baby's sex, they are typically performed for specific medical reasons.
Remember that these methods are medical procedures and should be performed by qualified medical professionals. There are no reliable methods to "calculate" a baby's sex based on traditional folklore or personal beliefs.
