Answer

To solve the question about the correct statements regarding LH (Luteinizing Hormone) in females, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Understanding LH**: LH, or Luteinizing Hormone, is secreted by the anterior lobe of the pituitary gland. It plays a crucial role in the female reproductive system.

2. **Evaluating Statement 1**: "Facilitates luteinisation of granulosa cells of ovulated follicle."
- This statement is **correct**. LH is responsible for the luteinization process, which involves the transformation of the granulosa cells of the ovulated follicle into luteal cells, leading to the formation of the corpus luteum.

3. **Evaluating Statement 2**: "Called ovulation hormone."
- This statement is also **correct**. LH is often referred to as the ovulation hormone because it triggers ovulation, the release of the ovum from the mature follicle.

4. **Evaluating Statement 3**: "Helps in milk secretion."
- This statement is **incorrect**. The hormone responsible for milk secretion is prolactin, not LH.

5. **Evaluating Statement 4**: "Activates Leydig cells to secrete androgen."
- This statement is **incorrect** in the context of females. While LH does stimulate Leydig cells in males to produce androgens, this function is not applicable in females.

6. **Conclusion**: Based on the evaluations:
- Statements 1 and 2 are correct.
- Statements 3 and 4 are incorrect.

Thus, the correct answer is **(b) 1,2 correct**.
