Hi it is a very intelligent approach towards future fertility.The most important factor that contributes to successful pregnancy is an egg quality and quantity which gradually declines with age.the decline starts after 32 years of age and becomes rapid from 35 years onwards.in some women the decline starts much earlier.I would advice you to get your ovarian reserve checked by a blood test called
AMH from a good lab.If it shows normal values you can postpone your pregnancy if it is borderline or low, postponement is not advisable.r regarding your partner a semen analysis from a good lab can predict his fertility potential as well
