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?

Do you think my sperm will be too weak or undeveloped to get her pregnant because I ejaculated too recently? Thanks for your help.
