No. The point of Perfect Forward Secrecy is that, even if you know one side's private key and have a log of all communications, you cannot determine what _session-key_ was agreed upon, and thus can't decrypt the rest of the session.
PFS means that even with private keys, you can't read sessions passively. Of course, it can't help with a MITM or taps on unencrypted data.
