<\/span><\/h2>\nAlthough the pregnancy may have occurred just a few weeks prior, the first ultrasound provides valuable information to specialists. Here are some of the parameters that can be evaluated:<\/p>\n
Amniotic cavity<\/strong><\/p>\nThis structure is visible even before the embryo itself. It appears as a dark space surrounded by a clearer border<\/strong>. Typically, it measures between 10 and 14 mm, although larger or smaller structures are completely normal and do not reflect any abnormalities in the pregnancy.<\/p>\nEmbryo<\/strong><\/p>\nIn the first scan after IVF, the embryo can be seen, although in many cases, its size may be too small to be visible. The embryo appears as a cellular structure measuring between 2 and 8 mm<\/strong>, attached to the yolk sac during the early weeks of gestation. Its growth rate is rapid, reaching around 1 mm per day. From these cells, all organs will develop.<\/p>\nHeartbeat<\/strong><\/p>\nThe heartbeat can be heard from approximately the sixth week. The heart rate is usually between 90 and 110 beats per minute<\/strong>, gradually increasing over time. Besides being a very special moment for patients, hearing the heartbeat is an indication of the embryo’s vitality.<\/p>\n
