What are the two main hormonal influences of breastfeeding?

Prolactin and Oxytocin
Estrogen and Progesterone
Testosterone and Insulin
Cortisol and Thyroxine

The correct answer is: Prolactin and Oxytocin

During breastfeeding, the two main hormonal influences are prolactin and oxytocin. Prolactin is responsible for milk production, promoting the growth of milk-secreting cells in the breast and initiating milk production after childbirth. Oxytocin, also known as the "love hormone," is responsible for the ejection or let-down of milk from the alveoli into the ducts, allowing the baby to receive the milk during nursing. These two hormones work together to ensure a successful breastfeeding experience for both the mother and the baby. The other options are incorrect: Estrogen and progesterone are involved in the menstrual cycle and pregnancy but are not the main hormonal influences of breastfeeding. Testosterone and insulin do not play significant roles in breastfeeding. Cortisol and thyroxine are important hormones for various bodily functions but are not the main hormonal influences of breastfeeding.
