In 2011, Sol{\'e} and and Planat stated that the Riemann Hypothesis is true if and only if the inequality $\frac{\pi^2}{6} \times \prod_{q\leq q_{n}}\left(1+\frac{1}{q} \right) > e^{\gamma} \times \log\theta(q_{n})$ is satisfied for all primes $q_{n}> 3$, where $\theta(x)$ is the Chebyshev function and $\gamma\approx 0.57721$ is the EulerMascheroni constant. Under the assumption of the Riemann Hypothesis is true and the inequality $\frac{\pi^2}{6.4} \times \prod_{q \leq q_{n}} \left(1 + \frac{1}{q} \right) > e^{\gamma} \times \log\theta(q_{n})$ is satisfied for infinitely many prime numbers $q_{n}$, then we prove that there is not any odd perfect number at all.
