If the circumstances mean the offspring could easily die, then as St.Thomas says no, they shouldn’t have relations until another option is found.
By your logic, any person who suffers from an illness that increases the chance of miscarriage should abstain throughout the course of the illness. There are many such illnesses and they are commonly the causes of infertility and miscarriage.
I have a friend who has suffered 15 miscarriages. The best that medicine has come up with is that she has a genetic incompatibility with her husband and continued miscarriage is the likely outcome of continued conceptions. Should they abstain because of this situation and the likelihood of continued loss of life?
I’m sure that St. Thomas was aware that advanced age is associated with increased loss of life and harm to the child, yet he does not speak out against marital relations toward the end of the childbearing years. I gave birth to a child at the age of 41 and then had three miscarriages, finally giving birth to another child at the age of 45. Since I did not have a history of miscarriage, it is clear that those losses were due to my age. Am I, therefore, guilty of their deaths because I chose not to abstain when I knew there was a significant risk of loss?
Do you see where your logic leads? Any infertile couple with known risk factors for miscarriage can be viewed as responsible for the loss of life associated with their condition. Rather than being applauded for their willingness to allow what God wills, even if it brings suffering, it casts suspicion upon them and their motives for continuing sexual relations when the outcome is likely continued loss of life.
I’m not a Thomist and cannot speak to the scope of his argument about menstruation, but I know a priest who is. I will ask his opinion of this when I see him on Saturday.
To deliberately seek this outcome is sinful; to accept it as an effect of the illness or treatment for an illness is not.
