title: Pregnancy after percutaneous epididymal sperm aspiration in an 81-year-old man with obstructive azoospermia.
abstract: There has been observed a trend to delay childbearing, reflecting couple's desire to have children at older ages. Maternal age is a well-known factor that influences the achievement of a pregnancy. In contrast, there are few studies examining the effect of paternal age on the outcomes of assisted reproductive technologies (ART), and results are conflicting. Our patient was vasectomised at the age of 60 years, and his wife was 38 years old. A total of four metaphase II oocytes were inseminated 4 h later (day 0) by intracytoplasmic sperm injection using spermatozoa from percutaneous epididymal sperm aspiration. On day 2, the three resulting embryos were transferred (two had four cells, and one had two cells). Two healthy infants were born at the 37th gestational week by caesarean section. Although the effect of paternal age on ART outcomes and results are conflicting, this case report contributes to point out that advanced age of the man has probably lesser negative influence in the reproductive function.
