Answer

To find the incorrect statement regarding pregnancy and fetal development, let's analyze each statement step by step:

1. **Statement 1**: HCG, HPL, and Relaxin are produced in women only during pregnancy.
- **Analysis**: This statement is correct. Human Chorionic Gonadotropin (HCG) and Human Placental Lactogen (HPL) are hormones produced by the placenta during pregnancy. Relaxin is also produced during pregnancy, particularly in the later stages, by the ovaries.

2. **Statement 2**: Blastocysts become embedded in the endometrium of the uterus and it leads to pregnancy.
- **Analysis**: This statement is correct. The blastocyst is the stage of the embryo that implants into the endometrium (the inner lining of the uterus), which is essential for establishing a pregnancy.

3. **Statement 3**: The first signs of the growing fetus may be noticed by listening to the heart sound carefully through a stethoscope.
- **Analysis**: This statement is correct. The fetal heartbeat can typically be detected by a stethoscope around the end of the first month of pregnancy, indicating the presence of a developing fetus.

4. **Statement 4**: The first movement of the fetus and appearance of hair on the head are observed during the sixth month.
- **Analysis**: This statement is incorrect. The first movements of the fetus, known as "quickening," are usually felt around the 5th month of pregnancy, not the sixth month. Hair may begin to appear around this time, but the statement incorrectly states the timing.

**Conclusion**: The incorrect statement is Statement 4.
