|Posthumous sperm retrieval (PSR) is a new and unconventional use of cryopreservation technology. Cryopreservation was used to preserve the human sperm for future use for the treatment of infertility in men by medical processes. In 1980, sperm obtained in the post-mortem state was first reported. The sociopolitical implications of PSR and the case law surrounding its use have increased in the last several years. Posthumous sperm retrieval for the purpose of procreation was first reported by Rothman in 1980.
Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
