The sex of a baby can typically be determined through an ultrasound around 18 to 20 weeks of pregnancy. However, some tests, such as non-invasive prenatal testing (NIPT), can reveal the baby's sex as early as 10 weeks into the pregnancy. It's important to note that the accuracy of determining sex can vary based on the method used and the positioning of the baby during the ultrasound.
If you mean, How many weeks of pregnancy before birth the answer is approximately 40 weeks from the last period or 38 weeks from conception. In humans the baby is considered full term any where from 38 weeks to 42 weeks from the last period. Each individual takes slightly longer or shorter to grow a baby. Nutrition, health, heredity, and the infant are all factors effecting hte length of pregnancy. No one can scientifically predict exactly when a baby will be born.
Usually between weeks 13-28 you will generally have an ultrasound that can detect the gender of your baby. If you have an ultrasound done during the first part of your second trimester it might be more difficult to tell. It is easier to determine if your baby is a boy than a girl. In other words, if your baby is a boy, there is no doubt but if your baby is a girl and the ultrasound is done at week 13, the sonographer might not be 100% certain that it is a girl because of positioning and just the overall smallness of your child at this point.
The typical duration of pregnancy, including the delivery of a baby boy or girl, is about nine months, or approximately 40 weeks, from the first day of the last menstrual period. This period is divided into three trimesters. While the exact timing of delivery can vary, most babies are born between 37 and 42 weeks of gestation.
