Serrano and Lima (2006) surveyed 30 couples to gain a better understanding of the impact of recurrent consecutive miscarriages on their relationship.  
- 90% of the couples were married and were in a relationship for an average of 6.66 years;
 - The average age of mothers was 31.73; the average age of fathers was 33.63;
 - 76.7% of the couples reported 3 miscarriages, 20% reported 4; 1 couple reported 6 miscarriages;
 - The couples in this study did not have living children and their most recent miscarriage occurred anywhere from three months to over one year prior to completing the survey.
