Perimortem and postmortem sperm acquisition: review of clinical data.

PURPOSE: To provide the clinicians with the most comprehensive medical information about sperm acquisition peri/postmortem. METHODS: The review was conducted according to the PRISMA statement. MEDLINE and Cochrane databases were searched up to January 2021. All studies reporting post or perimortem harvesting of sperm with any indication of an outcome, recognition and viability of sperm, and its utilization and treatment outcome were included. Studies that recorded cases but discussed only the ethical or legal issues without any information about the medical details were excluded. RESULTS: Twenty-four studies were included in this review. One hundred forty-eight cases were described; in 113 of them, sperm was retrieved. A variety of techniques for sperm acquisition were used. The data collected are limited and comparing the efficacy of the different approaches is not feasible. The longest time interval described between the death and viable sperm acquisition was 3 days. The sperm quality varies between the studies. One hundred thirty-six mature oocytes were injected with the retrieved sperm; the fertilization rate was 41%. Transfer cycles of 25 embryos and 8 live births are reported in the medical literature. CONCLUSION: The overall low quality and high heterogeneity of the available data impair the ability to draw definitive conclusions. However, it can be stated that sperm acquisition up to at least 3 days postmortem can result in the live birth of healthy offspring. Further studies are needed to clarify the medical questions regarding the best techniques, success rates, and wellbeing of the parties involved.

From Death to Life: Ethical Issues in Postmortem Sperm Retrieval as a Source of New Life.

This paper examines and critiques the ethical issues in postmortem sperm retrieval and the use of postmortem sperm to create new life. The article was occasioned by the recent request of the parents of a West Point cadet who died in a skiing accident at the Academy to retrieve and use his sperm to honor his memory and perpetuate the family name. The request occasioned national media attention. A trial court judge in New York in a two-page order authorized both the retrieval and use of the postmortem sperm.

Non-oncologic Indications for Male Fertility Preservation.

PURPOSE OF REVIEW: To explore non-oncologic indications for male fertility preservation. RECENT FINDINGS: Common scenarios in which male fertility could be irreversibly compromised include autoimmune conditions requiring treatment with cyclophosphamide, gender dysphoria prior to starting hormone therapy, military deployment, and critical illness. Fertility preservation should be considered with particular attention to the timing and logistics specific to each scenario. Recognition and familiarity with such situations will help physicians provide better counseling to patients and their families, improve the quality of decision-making, and ultimately reduce missed opportunities and regret.

Ethical Considerations in Post-Mortem Sperm Retrieval: A Comprehensive Review.

This comprehensive review delves into the moral and ethical dilemmas surrounding post-mortem sperm retrieval (PMSR) and its implications for creating new individuals. The paper examines the challenges posed by unusual requests for sperm retrieval from the deceased's widow and parents, as well as the broader socio-ethical considerations associated with PMSR. These requests have often been denied due to the absence of established laws and guidelines governing posthumous sperm retrieval and subsequent births, which were once deemed impossible. While some countries have implemented institutional policies to regulate its use to some extent, there remains a lack of standardized rules and procedures for the collection and retrieval of sperm after death. It is essential to introduce institutional guidelines to facilitate requests for assisted reproductive technology (ART) following successful sperm retrieval. Additionally, the development of PMSR legislation is necessary to ensure a proper balance between the moral rights and fundamental rights of the deceased, their family, and any current or future offspring, while providing adequate protection for all parties involved.

A case report on the prolonged viability of postmortem human testicular sperm.

Objective: To report a case of postmortem sperm retrieval with prolonged viability and motility. Design: Case report. Setting: Hospital and Medical Examiner Department. Patients: A 44-year-old African American male patient with a history of recreational marijuana use and occasional alcohol consumption who died from a cardiac arrest because of drug overdose. Interventions: Multiple testicular biopsies and sperm analyses. Main Outcome Measures: Sperm viability and motility of testicular biopsies at serial time intervals. Results: Sperm obtained from the testis in the morgue remained viable and motile even at 106 hours (>4 days) postmortem. Conclusions: Our study found that sperm obtained from the testis remained viable and motile even after being thawed after cryopreservation, even when obtained up to 100 hours postmortem. This may have implications on the timeframe that postmortem sperm retrieval can be performed successfully several days after death.

[Postmortem sperm retrieval: Two cases report and review of technical and legislative aspects in Spain]. / Recuperación espermática post mortem: análisis técnico y legislativo en España a propósito de dos casos.

INTRODUCTION AND OBJECTIVES: Advances in assisted reproductive techniques (ART) have caused an increase in requests for postmortem sperm retrieval (PMER). The use of these techniques is usually tied to legal, ethical and medical/casuistic problems. The objective of this work is to analyze technical and legal aspects of PMER in Spain using two real cases and to establish guidelines to help in decision-making after a PMER request. MATERIAL AND METHODS: Two real cases in which a PMER was requested and others published in Spain in recent years are presented. We proceed to an exposition of the techniques used in postmortem ART cases and specifically in PMER, and a detailed study of the current legal framework is carried out. RESULTS: In Spain we have a complete law on ART. Article 9 expressly requires an authorization from the deceased male partner for the use of his reproductive material in the following 12 months. Regarding the PMER, technical and logistical considerations require a quick and organized decision-making. The time until extraction should not exceed 24-36hours from death and a good choice of biological material is essential. CONCLUSIONS: Medical-scientific advances now allow PMER and the use of postmortem ART. A good knowledge of the technical, logistical and legal aspects is necessary for a fast and coordinated action.

A content analysis of posthumous sperm procurement protocols with considerations for developing an institutional policy.

OBJECTIVE: To identify and analyze existing posthumous sperm procurement (PSP) protocols in order to outline central themes for institutions to consider when developing future policies. DESIGN: Qualitative content analysis. SETTING: Large academic institutions across the United States. PATIENT(S) N/A INTERVENTION(S): We performed a literature search and contacted 40 institutions to obtain nine full PSP protocols. We then performed a content analysis on these policies to identify major themes and factors to consider when developing a PSP protocol. MAIN OUTCOME MEASURE(S): Presence of a PSP policy. RESULT(S): We identified six components of a thorough PSP protocol: Standard of Evidence, Terms of Eligibility, Sperm Designee, Restrictions on Use in Reproduction, Logistics, and Contraindications. We also identified two different approaches to policy structure. In the Limited Role approach, institutions have stricter consent requirements and limit their involvement to the time of procurement. In the Family-Centered approach, substituted judgment is permitted but a mandatory wait period is enforced before sperm use in reproduction. CONCLUSION(S): Institutions seeking to implement a PSP protocol will benefit from considering the six major building blocks of a thorough protocol and where they would like to fall on the spectrum from a Limited Role to a Family-Centered approach.
