What are the chances of conceiving naturally: 13m /ml sperm count, 70% motility, 12% morphology. Female 30yrs, fertility tests normal?

SEMEN. Anything can happen but with a low sperm count your chances are markedly decreased. There is something strange about having a slow sperm count and normal motility with poor morphology. I would have that semen analysis repeated and check the patient for a varicocele.
