Use of epididymal sperm for assisted reproduction in men with acquired, irreparable obstructive azoospermia

Abstract: Microsurgical epididymal sperm aspiration (MESA) and in vitro fertilization (IVF) is primarily offered to men with congenital absence of the vas deferens (CAVD). However, the IVF capacity of these epididymal sperm is low ( < 15%) and unpredictable. In this study, IVF and intracytoplasmic sperm injection (ICSI) results in patients with non-congenital, irreparable obstructive azoospermia were analysed. Thirty-three patients were evaluated for a total of 37 cycles of MESA and IVF. Most had obstruction secondary t… Show more

“…The standard treatment for male infertility due to irreparable obstructive azoospermia involves microsurgical epididymal sperm aspiration in combination with in vitro fertilization (e.g. Silber et al ., 1988 ; Patrizio et al ., 1995 ). Successful fertilization with epididymal aspirates clearly necessitates the selection of more mature spermatozoa, to ensure optimal levels of gamete motility and fertility.…”
