Which hormone is associated with formation of milk in the human females

Options

A. luteotrophin
B. prolactin
C. oxytocin
D. both a and b

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which hormone is responsible for the formation of milk in human females. This indicates that we need to identify a hormone that is directly involved in lactation.

2. **Identifying Mammary Glands**: In mammals, including humans, milk is produced in the mammary glands. These glands contain structures called alveoli, which are responsible for the secretion of milk.

3. **Hormones Involved in Lactation**: There are two key hormones involved in the lactation process:
- **Prolactin (also known as Luteotropic hormone)**: This hormone is secreted by the anterior pituitary gland and is primarily responsible for the formation of milk in the mammary glands.
- **Oxytocin**: This hormone is secreted by the posterior pituitary gland and is involved in the ejection of milk during breastfeeding, but it does not play a role in the formation of milk itself.

4. **Conclusion**: Based on the information, the hormone associated with the formation of milk in human females is **Prolactin** (or Luteotropic hormone).

5. **Final Answer**: Therefore, the correct answer to the question is **Prolactin**.
