In the early days of fertility treatment, it was certainly more common for women to have multiples. In the last 10 years, however, technological advancements have drastically reduced the potential for multiples, with the twin rate decreasing to around 16 percent and triplets to less than 1 percent of live births in women under 35. We continue to make great strides in this area, and through elective single embryo transfer (eSET), the incidence of multiple pregnancy has continued to drop at our practice.
