Waiting Period
Miscellaneous
When available, involvement of a hospital ethics committee is prudent. Hospitals may stipulate that they release their responsibility for the sperm following its procurement. No hospital employee should be forced to participate in PMSR.
PMSR Procedures
PMSR has been performed successfully using several techniques including electroejaculation (EEJ), testis biopsy, vasal or epididymal aspiration, and simple orchiectomy [6, 13]. All procedures can be carried out antemortem or postmortem with the exception of EEJ, which relies on an intact ejaculatory reflex, so it can only be performed prior to the cessation of cardiac activity [8, 13, 40]. The authors recommend obtaining a generous tissue sample since the decedent’s fertility status is usually unknown, there is no risk of causing hypogonadism or infertility in the future, multiple cycles of IVF/ICSI are often required to achieve a pregnancy, and there will only be one opportunity to retrieve sperm.
Electroejaculation
EEJ is the preferred method of sperm retrieval prior to the cessation of cardiac activity. EEJ delivers wavelike electrical stimulation to pelvic nerves via a rectal probe to trigger ejaculation [42]. EEJ is minimally invasive and can yield a large quantity of motile sperm, making it an appealing option for cryopreservation. There are two major drawbacks to EEJ. It requires availability of an FDA-approved Seager Electroejaculator (Dalzell Medical Systems, The Plains, VA), as well as a specialized urologist with experience performing EEJ.
Testis Biopsy
The authors recommend open testicular biopsy for PMSR following cardiac death. Open biopsy yields a large volume of testicular tissue and can be performed without specialized instruments by general urologists, general surgeons, or a pathologist during an autopsy. Testicular tissue can also be stored in sperm-friendly medium overnight, which minimizes a potential barrier to cryopreservation since processing can occur during “social” work hours [41]. Microscopic testis biopsy is favored by others, who argue that open biopsy removes an excessive amount of tissue. Percutaneous testis biopsy requires availability of a specialized urologist and, even in experienced hands, only yields a small volume of tissue.
Simple Orchiectomy
Orchiectomy removes the entire testicle and epididymis en bloc through a scrotal incision. If there is concern for impaired spermatogenesis this approach may be prudent to maximize the volume of testicular tissue procured. Similar to open testis biopsy, orchiectomy can be performed by a general urologist, general surgeon, or pathologist without specialized instruments.
Vasal or Epididymal Aspiration
Aspiration of the epididymis or vas deferens for PMSR has also been described, and can yield motile sperm for cryopreservation [9]. Proponents of vasal aspiration favor this approach since it is minimally intrusive and prevents mixture of sperm with the decomposing body [9]. General urologists who perform vasectomies will be comfortable with the vasal dissection and manipulation, although they are unlikely to have experience with the actual aspiration. Epididymal aspiration is technically difficult and requires surgical expertise.
Conclusions
PMSR is a controversial practice which raises a myriad of ethical questions, yet it is being requested with increasing frequency worldwide [2, 39]. Successful PMSR requires swiftly navigating the logistical issues summarized in this chapter and has been described using a variety of retrieval procedures. No ethical calculus or system of judgement could conclusively resolve the ethical questions surrounding PMSR given the intense circumstances under which requests arise and when the interests of all involved parties are considered. The legal precedent for PMSR is highly variable and in many places nonexistent. In the absence of any official international or national guidelines, experts have called on medical centers to develop their own institutional policies to help guide physicians and hospital ethics committees considering requests for PMSR.
