Same Blood Type Parents: Pregnancy & Fertility in Your 40s

Question
Greeting!
Is the childbirth possible when both man & woman having same blood group and they are middle aged, in their 40s'?
Thanks in advance.
Regards

Answer
S,

There is no problem with pregnancy when both parents have the exact same blood type.  Conception is still possible for a woman in her forties, although it can be more difficult to conceive as her fertility begins to decline in her mid thirties.


Best,
