Yes, it is. For example, it can happen that a particular circumstance in your life (like too high stress levels) caused azoospermia in the first analysis due to changes in hormone levels. However, after another semen analysis (done 4 months after), if the special circumstance has disappeared, it is likely that your hormones have returned to normal levels, and subsequently sperm production is normal again.
My first semen analysis says azoospermia and the second says oligospermia, is it normal?
