Quotes from the segment:

48 Corespondent Erin Moriarty: "It seems as all these women that we have spoken to, that they start seeing the symptoms after they give birth.  Is there that they are somehow connected?" 

Dr. Jennifer Berman: "I believe that there is some connection between what happens during and after pregnancy and (womens)  testosterone levels.  Why it happens we don't know but it clearly does."
