Clinical data of 162 patients with cryptorchidism who underwent Micro-TESE due to infertility from December 2015 to May 2020 in the First Affiliated Hospital of Nanjing Medical University were analyzed retrospectively. In the univariate analysis, significant differences in the age of patient at the time of orchidopexy (median [interquartile range, IQR]: 7.0 [4.0\u201311.0] years\n vs<\/jats:italic>\n 11.5 [9.0\u201314.5] years,\n P<\/jats:italic>\n < 0.001), interval between orchidopexy and Micro-TESE (mean \u00b1 standard deviation: 17.5 \u00b1 5.0 years\n vs<\/jats:italic>\n 14.4 \u00b1 4.4 years,\n P<\/jats:italic>\n < 0.001), severity of cryptorchidism (unilateral [62.8%]\n vs<\/jats:italic>\n bilateral [31.6%],\n P<\/jats:italic>\n < 0.001; location of cryptorchidism, intra-abdominal [27.3%]\n vs<\/jats:italic>\n inguinal [44.8%]\n vs<\/jats:italic>\n suprascrotal [66.7%],\n P<\/jats:italic>\n < 0.001), volume of the dominant testis (median [IQR]: 17.00 [15.00\u201319.00] ml\n vs<\/jats:italic>\n 14.50 [11.75\u201316.25] ml,\n P<\/jats:italic>\n < 0.001), and levels of follicle-stimulating hormone (FSH;\n P<\/jats:italic>\n = 0.004) and testosterone (\n P<\/jats:italic>\n = 0.006) were observed between the successful and failed sperm extraction groups. After conducting the multivariate analysis, four of these factors, including unilateral\/bilateral cryptorchidism (\n P<\/jats:italic>\n < 0.001), location of cryptorchidism (\n P<\/jats:italic>\n = 0.032), age of orchidopexy (\n P<\/jats:italic>\n < 0.001), and dominant testicular volume, were adopted in the clinical prediction model to evaluate preoperatively the success rate of Micro-TESE for patients with NOA and cryptorchidism. The likelihood of successful sperm retrieval by Micro-TESE in men with NOA and cryptorchidism increased in patients with mild forms of cryptorchidism.\n <\/jats:p>","DOI":"10.4103\/aja2021102","type":"journal-article","created":{"date-parts":[[2022,1,17]],"date-time":"2022-01-17T10:19:22Z","timestamp":1642414762000},"page":"503-508","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":23,"title":["Predictive factors for successful sperm retrieval by microdissection testicular sperm extraction in men with nonobstructive azoospermia and a history of cryptorchidism"],"prefix":"10.4103","volume":"24","author":[{"given":"Xing-Lin","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Urology, The First Affiliated Hospital of Nanjing Medical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Ang","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Urology, The First Affiliated Hospital of Nanjing Medical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao-Han","family":"Ren","sequence":"additional","affiliation":[{"name":"Department of Urology, The First Affiliated Hospital of Nanjing Medical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Urology, The First Affiliated Hospital of Nanjing Medical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guang-Yao","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Urology, The First Affiliated Hospital of Nanjing Medical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhong-Wen","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Urology, The First Affiliated Hospital of Nanjing Medical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Urology, The First Affiliated Hospital of Nanjing Medical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Qin","sequence":"additional","affiliation":[{"name":"Department of Urology, The First Affiliated Hospital of Nanjing Medical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shi-Feng","family":"Su","sequence":"additional","affiliation":[{"name":"Department of Urology, The First Affiliated Hospital of Nanjing Medical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2022,9]]},"reference":[{"key":"B1-20240829","doi-asserted-by":"crossref","first-page":"1148","DOI":"10.1016\/S0022-5347(01)67015-0","article-title":"The results of surgical therapy for cryptorchidism: a literature review and analysis","volume":"154","author":"Docimo","year":"1995","journal-title":"J Urol"},{"key":"B2-20240829","doi-asserted-by":"crossref","first-page":"314","DOI":"10.1016\/j.juro.2007.08.158","article-title":"The true incidence of cryptorchidism in Denmark","volume":"179","author":"Cortes","year":"2008","journal-title":"J Urol"},{"key":"B3-20240829","doi-asserted-by":"crossref","first-page":"142","DOI":"10.1007\/s11934-004-0028-4","article-title":"The relationship of cryptorchidism to fertility","volume":"5","author":"Trussell","year":"2004","journal-title":"Curr Urol Rep"},{"key":"B4-20240829","doi-asserted-by":"crossref","first-page":"260","DOI":"10.1001\/archpedi.1997.02170400046008","article-title":"Paternity after bilateral cryptorchidism.
