14 Weeks of Pregnancy | #SecondTrimester | #FetalDevelopment in #Pregnancy

______
At 14 weeks of pregnancy, ultrasonography can more easily distinguish the external sex organs [1]. You may be able to find out the biological sex of your fetus at your next ultrasound appointment if desired. The prostate gland is developing in male fetuses, and the ovaries are moving into position in female fetuses [2].

The fetus can now produce hormones with its functional thyroid gland [2]. Production of red blood cells has decreased in the liver and started in the spleen [1].

The fetus’s neck is more well-defined, and its palate (the roof of the mouth) is forming [1,2]. By the end of this week, ossification (the process of bone replacing skeletal cartilage) is apparent in the skull [1].
