### Step-by-Step Solution:

1. **Examine Option 1:**
- The statement claims that according to the 2001 census, the population growth rate was 1.7%.
- This is indeed correct as per the census data. The population growth rate of 1.7% means that the population increases by 17 per thousand per year.
- Additionally, it is accurate that with this growth rate, the population would double in approximately 33 years.

**Conclusion:** Option 1 is correct.

2. **Examine Option 2:**
- This option states that the marriageable age for males is 21 years and for females is 18 years.
- This is also correct as per the legal standards in India. The minimum age for marriage is indeed 21 for males and 18 for females.

**Conclusion:** Option 2 is correct.

3. **Examine Option 3:**
- The statement claims that an ideal contraceptive should be reversible.
- This is correct as well. An ideal contraceptive method should be reversible, user-friendly, easily accessible, and effective.

**Conclusion:** Option 3 is correct.

4. **Examine Option 4:**
- This option states that the problem of infertility in India lies most often in the female partner.
- This statement is incorrect. Infertility can affect both males and females, and it is not accurate to say that it lies most often in one gender. Infertility issues can arise from various factors affecting both partners.

**Conclusion:** Option 4 is incorrect.

### Final Answer:
The incorrect statement is **Option 4**: "The problem of infertility in India lies most often in the female partner."
