How Can I Determine the Gender of My Baby After Pregnancy?

During pregnancy, the gender of the baby can be determined through methods such as ultrasound scan, amniocentesis, and chorionic villus sampling. Here are the details:

Ultrasound is a type of sound wave that has been reported to have no adverse effects on the fetus so far, making it widely used in obstetrics and gynecology. According to experts in gynecological hospitals, when using ultrasound to diagnose the gender of the fetus, the accuracy for male babies can reach over 95%, while the reliability for female babies is only around 85%.

Amniocentesis is mainly used to diagnose whether the fetus has chromosomal or neural tube defects, usually performed during weeks 16 to 20 of pregnancy. Since it can reveal the chromosomes of the fetus, it can also determine the gender. The accuracy can reach 99%, but there is a 1% risk of miscarriage. Therefore, the medical community does not recommend amniocentesis solely for the purpose of determining the gender of the fetus.

Also known as "chorionic villus biopsy", this procedure is usually performed during weeks 8 to 10 of pregnancy. Its main purpose is similar to amniocentesis, which is to diagnose whether the fetus's chromosomes are normal. However, some people also use it to determine the gender of the fetus. The accuracy rate can reach 98%. Although chorionic villus sampling can determine the gender of the fetus around week 10 of pregnancy, it may cause miscarriage (3% to 5%) and potentially harm the fetus, resulting in limb defects. Therefore, it is best not to undergo this test solely for the purpose of determining the gender of the fetus.
