Which hormone is responsible for the let-down reflex in breastfeeding women?
A
Oxytocin
B
Progesterone
C
Prolactin
D
Thymosin
Explanation: 

Detailed explanation-1: -Oxytocin. The oxytocin reflex is also sometimes called the “letdown reflex” or the “milk ejection reflex”. Oxytocin is produced more quickly than prolactin. It makes the milk that is already in the breast flow for the current feed, and helps the baby to get the milk easily.

Detailed explanation-2: -Oxytocin is an essential lactation hormone released during breastfeeding that causes milk ejection and appears to have calming effect on the mother.

Detailed explanation-3: -Suckling also induces a release of oxytocin from nerves within the brain where oxytocin facilitates both physiological and psychological adaptations for breastfeeding and motherhood. Oxytocin promotes prolactin release and thereby milk production.

Detailed explanation-4: -The let-down reflex is what makes breastmilk flow. When your baby sucks at the breast, tiny nerves are stimulated. This causes two hormones – prolactin and oxytocin – to be released into your bloodstream. Prolactin helps make the milk, while oxytocin causes the breast to push out the milk.
