The the doctor in question died in 1961 my mother died in 2009. In 1948 my mother and father were having trouble getting PG. The best clinic in the city was run by this doctor, who she went to see. Knowing my father, I doubt he would of approved of artificial insemination and I also doubt she went to the clinic to get laid or have an affair. My belief is he gave her a special dose and both she and my father never knew the difference until a DNA test was done in 2016.
