Under the influence of androgen, the genital tubercle forms the penis by forming a tubular urethra within the penile shaft. Without the effect of the androgen, the genital tubercle differentiates into the clitoris, and a lack of formation of the urethra within the clitoris is observed. Even though there are similarities during the development of the glans penis and glans clitoris, the complex canalization occurring along the penile shaft eventually leads to a morphological difference between the penis and clitoris. Based on the morphological differences, the main goal of this study was to define the vascular and neuronal anatomy of the developing penis and clitoris between 8 and 12\u2009weeks of gestation using laser scanning confocal microscopy. Our results demonstrated there is a co\u2010expression of CD31, which is an endothelial cell marker, and PGP9.5, which is a neuronal marker in the penis where the fusion is actively occurring at the ventral shaft. We also identified a unique anatomical structure for the first time, the clitoral ridge, which is a fetal structure running along the clitoral shaft in the vestibular groove. Contrary to previous anatomical findings which indicate that the neurovascular distribution in the developing penis and clitoris is similar, in this study, laser scanning confocal microscopy enabled us to demonstrate finer differences in the neurovascular anatomy between the penis and clitoris.<\/jats:p>","DOI":"10.1111\/joa.14029","type":"journal-article","created":{"date-parts":[[2024,2,29]],"date-time":"2024-02-29T04:51:02Z","timestamp":1709182262000},"page":"35-49","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Neurovascular anatomy of the developing human fetal penis and clitoris"],"prefix":"10.1111","volume":"245","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2147-5067","authenticated-orcid":false,"given":"Sena","family":"Aksel","sequence":"first","affiliation":[{"name":"Department of Urology University of California  San Francisco California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amber","family":"Derpinghaus","sequence":"additional","affiliation":[{"name":"Department of Urology University of California  San Francisco California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mei","family":"Cao","sequence":"additional","affiliation":[{"name":"Department of Urology University of California  San Francisco California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Urology University of California  San Francisco California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerald","family":"Cunha","sequence":"additional","affiliation":[{"name":"Department of Urology University of California  San Francisco California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurence","family":"Baskin","sequence":"additional","affiliation":[{"name":"Department of Urology University of California  San Francisco California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,2,28]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/den098"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.diff.2019.08.005"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.diff.2019.11.001"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.diff.2018.08.001"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5347(01)62711-3"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5347(01)68052-2"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1289\/ehp.011091175"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41443-022-00561-9"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/cne.900500110"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.diff.2017.07.003"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.diff.2019.07.005"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.AOG.0000154159.75022.11"},{"key":"e_1_2_10_14_1","first-page":"958","article-title":"Ontogeny of the estrogen receptor in the human fetal uterus","volume":"80","author":"Glatstein I.Z.","year":"1995","journal-title":"The Journal of Clinical Endocrinology & Metabolism"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2017.02.037"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.diff.2018.09.003"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2019.06.048"},{"key":"e_1_2_10_18_1","volume-title":"Surgery of the penis and urethra.
