Cryopreservation solution with 10% PVP was added to 30 \u00b5L of spermatozoa suspension in a 1:1 ratio, with a final PVP concentration of 5%. Then, polycarbonate capillaries for oocyte denudation with a diameter of 170 \u00b5m were filled with 60 \u00b5L of the resulting sperm suspension. After that, the capillaries were placed for 10 minutes at a height of 15 cm above liquid nitrogen and immersed into liquid nitrogen. To warm the spermatozoa, the capillaries were immersed in a water bath at a temperature of 40\u00b0C for 30 seconds. Oocyte fertilization was performed by ICSI. Zygotes were cultured\n                    <jats:italic toggle=\"yes\">in vitro<\/jats:italic>\n                    for 5 days to the blastocyst stage. More than 100 spermatozoa were obtained after percutaneous epidydimal sperm aspiration, of which 80% were motile. After cryopreservation, storage for 3 months in liquid nitrogen, and thawing, 72% of the total sperm cells remained motile. Ten oocyte\u2013cumulus complexes were found after follicle puncture, and eight metaphase II stage oocytes were fertilized using ICSI. After 18 hours, two pronuclei were found in seven (88%) of the oocytes. An analysis of the morphological characteristics of 5-day-old embryos showed that four (57%) of them reached the blastocyst stage. One embryo was transferred, and the remaining embryos were cryopreserved (vitrified). The onset of pregnancy was detected on the 14th day after embryo transfer, and one healthy girl (3300 g) was born at term.\n                  <\/jats:p>","DOI":"10.1089\/bio.2023.0032","type":"journal-article","created":{"date-parts":[[2024,3,18]],"date-time":"2024-03-18T07:44:10Z","timestamp":1710747850000},"page":"597-599","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Technology for Biobanking of Epididymal Spermatozoa from Patient with Obstructive Azoospermia: Case Report about Baby Born after Conventional Freezing Only with a Nonpermeable Cryoprotectant 360 kDa Polyvinylpyrrolidone"],"prefix":"10.1177","volume":"22","author":[{"given":"Maryna","family":"Petrushko","sequence":"first","affiliation":[{"name":"Institute for Problems of Cryobiology and Cryomedicine Nasu, Kharkiv, Ukraine."},{"name":"ART-clinic of Reproductive Medicine, Kharkiv, Ukraine."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4993-9129","authenticated-orcid":false,"given":"Taisiia","family":"Yurchuk","sequence":"additional","affiliation":[{"name":"Institute for Problems of Cryobiology and Cryomedicine Nasu, Kharkiv, Ukraine."},{"name":"Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences, Olsztyn, Poland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Volodymyr","family":"Piniaiev","sequence":"additional","affiliation":[{"name":"Institute for Problems of Cryobiology and Cryomedicine Nasu, Kharkiv, Ukraine."},{"name":"ART-clinic of Reproductive Medicine, Kharkiv, Ukraine."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evgenia","family":"Isachenko","sequence":"additional","affiliation":[{"name":"Research Group for Reproductive Medicine, Department of Obstetrics and Gynecology, Medical Faculty, Cologne University, Cologne, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gohar","family":"Rahimi","sequence":"additional","affiliation":[{"name":"Research Group for Reproductive Medicine, Department of Obstetrics and Gynecology, Medical Faculty, Cologne University, Cologne, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Mallmann","sequence":"additional","affiliation":[{"name":"Research Group for Reproductive Medicine, Department of Obstetrics and Gynecology, Medical Faculty, Cologne University, Cologne, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3674-543X","authenticated-orcid":false,"given":"Volodimir","family":"Isachenko","sequence":"additional","affiliation":[{"name":"Research Group for Reproductive Medicine, Department of Obstetrics and Gynecology, Medical Faculty, Cologne University, Cologne, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,12,18]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2019.06.008"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cryobiol.2021.02.009"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12958-020-00607-x"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2020.03.032"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cryobiol.2021.09.013"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1208\/s12249-015-0394-x"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2818.1977.tb00036.x"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cryobiol.2021.09.009"}],"container-title":["Biopreservation and Biobanking"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1089\/bio.2023.0032","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1089\/bio.2023.0032","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1089\/bio.2023.0032","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T13:33:15Z","timestamp":1777383195000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1089\/bio.2023.0032"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,12]]},"references-count":8,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2024,12]]}},"alternative-id":["10.1089\/bio.2023.0032"],"URL":"https:\/\/doi.org\/10.1089\/bio.2023.0032","relation":{},"ISSN":["1947-5535","1947-5543"],"issn-type":[{"value":"1947-5535","type":"print"},{"value":"1947-5543","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,12]]}}}
