Patients that have had a vasectomy and are not good candidates for a vasectomy reversal or have failed a vasectomy reversal. Some patients may be good candidates for a vasectomy reversal but choose to do a sperm harvesting surgery in order to do in vitro fertilization (IVF) procedures in order to increase the possibility of pregnancy if the spouse is older than 35.
Some patients need a Sperm Harvesting Surgery due to congenital absence of the sperm tubes that carry sperm from the testicle or from obstruction of these tubes as a complication of prostate or inguinal hernia surgeries.
Some patients have a neurological condition that blocks the nerve signals responsible for ejaculation and sometimes patients have had trauma that led to paraplegia and associated ejaculation problems.
