Surgical sperm retrieval: a review of current practice.
Although pregnancies were achieved after surgical sperm retrieval and in vitro fertilization 8 years before the introduction of intracytoplasmic sperm injection (ICSI), it is the development of ICSI that has led to the rapid expansion of surgical procedures to obtain sperm from azoospermic males for use in assisted conception cycles. The natural desire for couples to achieve a pregnancy using their own gametes and a national shortage of donor sperm have driven the demand for an expansion of this service. Males who have previously been considered unable to father their own genetic child can now be offered treatment, which, in most cases, will lead to the recovery of sperm for use in treatment. This article considers the development of the techniques available to clinicians and provides an overview of the many treatments (and their acronyms) to assist clinicians unfamiliar with the practicalities of surgical sperm retrieval. In reviewing the current published studies, we also offer some guidelines as to the optimization of the potential future provisions of surgical sperm retrieval treatments for azoospermic males, either secondary to obstruction (particularly after vasectomy) or from non-obstructive causes.
