How long does it take for sperm to redevelop after ejaculation?

My wife and I are trying to conceive. Is it true that we should wait 48 hours between the times we have sex so my sperm can redevelop? The thing is, I ended up ejaculating in my sleep and then had sex with my wife about six hours later because it was one of the key days for getting pregnant. Do you think my sperm will be too weak or undeveloped to get her pregnant because I ejaculated too recently? Thanks for your help.
