A scan for the purposes of sex determination is known as a Sexing or Gender Scan and can be done anytime from 16 weeks onwards. It would not be a bad idea to wait until having the full 4D or HD scan to discover the sex of your little one so you can make it an exciting all-in-one event.
But if you just cannot wait then just have it at 16 weeks. One thing we pride ourselves in is the ability to get our customers nice and relaxed ready for what should always be an enjoyable experience. We have made sure to remove the cold clinical experiences associated with hospital visits by creating an atmosphere of homeliness and comfort.
During the scan your friends and family can also watch the flat screen from 5 chairs we always keep in the scanning room. We keep paperwork to a minimum and only require that you first use our standard form to select the type of scan you require as well as fill out a simple consent form. If you want to know the sex of the baby, we will point that out to you during the scan but if you would rather wait until the Big Day to find out then that’s fine too.
Our skilful sonographers will tactically manoeuvre to avoid those revealing angles. The scanning procedure should normally take around 10 to 15 minutes although this could take a little longer should your baby decide to hide. Following the scan , you will be allowed to choose two magical angles to save as 6×4 glossy photos.
