Answer

To solve the question of identifying the incorrect statement regarding STDs (Sexually Transmitted Diseases), we can analyze each of the provided statements one by one.

### Step-by-Step Solution:

1. **Statement 1**: "Other than sexual intercourse, STDs can be transmitted through infected medical devices, blood transfusion or from the mother to fetus."
- **Analysis**: This statement is true. STDs can indeed be transmitted through various means other than sexual intercourse, including medical devices, blood transfusions, and from an infected mother to her fetus.

2. **Statement 2**: "Infected females may often be asymptomatic and hence may remain unrecognized for long."
- **Analysis**: This statement is also true. Many females infected with STDs can be asymptomatic for extended periods, which means they may not show any symptoms and thus may not realize they are infected.

3. **Statement 3**: "Failure of timely detection of and treatment may lead to ectopic pregnancies, pelvic inflammatory diseases and infertility."
- **Analysis**: This statement is true as well. If STDs are not detected and treated in a timely manner, they can lead to serious complications such as ectopic pregnancies, pelvic inflammatory disease, and infertility.

4. **Statement 4**: "Except HIV, all STDs are completely curable with proper treatment."
- **Analysis**: This statement is incorrect. While many STDs are treatable, Hepatitis B is a notable exception as it is not completely curable. Therefore, this statement is false.

### Conclusion:
The incorrect statement among the options is **Statement 4**: "Except HIV, all STDs are completely curable with proper treatment."
