Which of the following cannot be considered as an advantage of amniocentesis ?

Options

A. Parental diagnostics
B. Detection of biochemcal abnormalities
C. Detection of congential defects
D. Determination of sex to abort female foetus

Answer

To solve the question "Which of the following cannot be considered as an advantage of amniocentesis?", we will analyze each option provided in the context of what amniocentesis is and its applications.

### Step-by-Step Solution:

1. **Understand Amniocentesis**:
- Amniocentesis is a medical procedure used to obtain amniotic fluid from the amniotic sac surrounding a developing fetus. This fluid contains fetal cells and various substances that can be analyzed for genetic and biochemical conditions.

2. **Evaluate the Options**:
- **Option 1: Parental Diagnosis**:
- Amniocentesis can be used for parental diagnosis, as it helps in identifying genetic disorders in the fetus. This is considered an advantage.
- **Option 2: Detection of Biochemical Abnormalities**:
- This procedure allows for the detection of biochemical abnormalities in the fetus, which is indeed an advantage of amniocentesis.
- **Option 3: Detection of Congenital Defects**:
- Amniocentesis is effective in detecting congenital defects early in the pregnancy. This is also an advantage of the procedure.
- **Option 4: Determination of Sex of the Fetus**:
- While amniocentesis can determine the sex of the fetus, using this procedure solely for sex determination is illegal in many places due to ethical concerns surrounding sex-selective practices. Therefore, this cannot be considered an advantage of amniocentesis.

3. **Conclusion**:
- Based on the evaluation, the option that cannot be considered an advantage of amniocentesis is **Option 4: Determination of sex of the female fetus**.

### Final Answer:
The correct answer is **Option 4: Determination of sex of the female fetus**.
