In pregnancy, which stages of Lactogenesis occur?

1. 2 and 3

2. 1 and 2

3. 3 and 4

4. None occur in pregnancy

The correct answer is: 1 and 2

During pregnancy, the two stages of Lactogenesis that occur are Lactogenesis I and Lactogenesis II. Lactogenesis I begins during the later stages of pregnancy when the breasts start producing colostrum, the first milk rich in antibodies and nutrients for the baby. Lactogenesis II is the stage where there is a significant increase in milk production after childbirth due to hormonal changes and increased demand for milk by the baby. Choices A, C, and D are incorrect because all stages of Lactogenesis occur either during pregnancy or after childbirth.
