[Tex/LaTex] logo in the first page only

beamerthemestitles

I want to insert the logo in the title page only. However, it displays on all pages!
How can I make these two figurs display as logo in the title page only?

I type in the preamble:

\logo{%
   \includegraphics[scale=.2]{fig1.pdf}\hspace*{4.75cm}~%
   \includegraphics[scale=.2]{fig2.jpg}\hspace*{0.75cm}%
   }

then

\begin{document}

\maketitle

\begin{frame}
\frametitle{}
...
\end{frame}

The command to be used to display the logo only in the titlepage is \titlegraphic.

For example:

\documentclass{beamer}

\author{Me}
\title{The title}
\institute{My institute}

% logo of my university
\titlegraphic{\includegraphics[width=2cm]{logopolito}\hspace*{4.75cm}~%
   \includegraphics[width=2cm]{logopolito}
}

\begin{document}
\begin{frame}
\titlepage
\end{frame}

\begin{frame}{Test 1}
test
\end{frame}

\begin{frame}{Test 2}
test
\end{frame}
\end{document}

I report the first two frames:
