PURPOSE OF REVIEWThe aim of this review is to provide an overview of surgical treatment options for male infertility including varicocelectomy, treatment of ejaculatory duct obstruction, vasovasostomy, and sperm extraction, and to review recent advances in techniques and technologies that may improve operative outcomes.
RECENT FINDINGSMicroscopic subinguinal varicocelectomy has been shown to have the highest success rates with lowest rates of complications, and may be facilitated by the use of Doppler, indocyanine green angiography, and the 4K3D operating video microscope. The standard treatment for ejaculatory duct obstruction by transurethral resection of the ejaculatory ducts has changed little over time, but vesiculoscopy may allow for temporary dilation of an obstruction to allow for natural conception, while also offering diagnostic capabilities. Use of the robotic platform has gained popularity for vasectomy reversals but controversy remains regarding the cost-effectiveness of this option. Recently, a reinforcing suture technique has been described for vasovasostomy to minimize anastomotic breakdown and reversal failure. Finally, gray-scale and color-enhanced ultrasound may improve ability to predict successful sperm retrieval during extraction procedures.
SUMMARYThough the fundamentals of surgical treatment options for male infertility have changed little with time, technological advancements have contributed to improved surgical outcomes over recent years.
