Answer

To determine what is true for "Lactational Amenorrhea," let's analyze each statement step by step.

### Step-by-Step Solution:

1. **Statement I: It means absence of menstruation.**
- **True**: Lactational amenorrhea refers to the temporary absence of menstruation that occurs during breastfeeding.

2. **Statement II: Ovulation does not occur during the lactational period.**
- **True**: During the lactational period, particularly in the first six months postpartum, ovulation is typically suppressed due to hormonal changes associated with breastfeeding.

3. **Statement III: Chances of failure of contraception are almost nil up to six months following parturition.**
- **True**: The chances of conception are very low during the first six months of exclusive breastfeeding, making it an effective natural contraceptive method.

4. **Statement IV: Side effects are almost nil.**
- **True**: Since lactational amenorrhea is a natural method of contraception, it generally does not have the side effects associated with hormonal contraceptives.

5. **Statement V: Contraceptive efficiency reduces after the period of intense lactation.**
- **True**: After the initial six months of intense lactation, the effectiveness of lactational amenorrhea as a contraceptive method decreases as ovulation may resume.

6. **Statement VI: It is a natural method of contraception.**
- **True**: Lactational amenorrhea is indeed considered a natural method of contraception.

7. **Statement VII: It increases phagocytosis of sperms.**
- **False**: This statement is incorrect. Phagocytosis of sperm is not a characteristic of lactational amenorrhea. It is more associated with certain contraceptive devices, such as copper IUDs.

### Conclusion:
The true statements regarding lactational amenorrhea are I, II, III, IV, V, and VI. Statement VII is false.
