The fetal stage is the final phase of prenatal development, occurring from the ninth week of pregnancy until birth. During this stage, the developing organism is referred to as a fetus, and it undergoes significant growth and maturation of organs and systems. Key developments include the growth of body structures, the formation of functional organs, and increasing complexity in the nervous system. By the end of this stage, the fetus is typically fully developed and prepared for birth.
A fetal pole is typically visible on ultrasound around 6 weeks of pregnancy. At this stage, you may also be able to see a heartbeat in the fetal pole.
The fetal period of development occurs during the third stage of prenatal development, which is the fetal stage.
When a doctor reports that the internal cervical os is closed and there is no demonstrable fetal echo, it typically indicates that the cervix is not dilated, which is a normal finding in early pregnancy. However, the absence of a fetal echo suggests that there is no visible fetus or fetal heartbeat at this stage, which could imply a very early pregnancy or a possible miscarriage. Further evaluation and follow-up scans may be necessary to determine the status of the pregnancy.
The fetal period occurs during the third stage of prenatal development.
Fetal bradycardia during pregnancy can be caused by factors such as maternal hypotension, maternal hypothermia, fetal hypoxia, umbilical cord compression, and certain medications.
The term that describes a developing offspring after the first eight weeks of human pregnancy is "fetus." During this stage, the major structures and organs have formed, and the fetus continues to grow and develop until birth. The fetal stage lasts from the ninth week of pregnancy until delivery.
The fetal mass increases at the greatest rate between weeks 9 to 14 of pregnancy. This period is known as the "growth spurt" stage of fetal development, where the baby's organs and body structures rapidly form and grow.

A tiny fetal pole refers to the early developmental stage of an embryo during pregnancy, typically seen in an ultrasound around 6-7 weeks gestation. It is the first identifiable structure that indicates the presence of an embryo and is usually a small, thickened area along the gestational sac. The size and development of the fetal pole can provide important information about the viability of the pregnancy. If the fetal pole is unusually small or not developing as expected, it may raise concerns about potential complications.
Fetal growth occurs in three main stages: the germinal stage, embryonic stage, and fetal stage. The germinal stage lasts from conception to about two weeks, where the fertilized egg implants itself in the uterus. The embryonic stage, from two to eight weeks, involves the development of essential organs and structures. Finally, the fetal stage, from nine weeks until birth, is characterized by rapid growth and maturation of the organs, preparing the fetus for life outside the womb.
Before the fetal stage is the embryonic stage. The embryo develops into the fetus.
The length of gestation in a fetal pig can be determined by counting the number of days from the date of fertilization to the date of birth or by estimating based on the developmental stage of the fetus. Ultrasound imaging is commonly used to monitor fetal development and determine gestational age in pigs. Hormone levels and physical changes in the sow can also provide clues to the stage of pregnancy.
