This case series reports clinical and ultrasound findings in five adult (aged 1\u20136 yr) female geckos (three leopard geckos [Eublepharis macularius], one crested gecko [Correlophus ciliatus], and one gargoyle gecko [Rhacodactylus auriculatus]) diagnosed with unilateral ovarian torsion between 2019 and 2023. All animals presented with acute weakness associated with coelomic distension, and one suffered from chronic diarrhea and cachexia. Coelomic ultrasound examination (12-MHz linear probe) revealed signs of bilateral follicular stasis and oophoritis in all cases (heterogenic follicles \u22641.3 cm diameter) associated with a large anechoic periovarian rim and a hyperechoic chord, consistent with twisted ovarian vessels. Blood supply to ovarian structures was not detected using a Doppler flow, and a unilateral ovarian torsion was diagnosed in all geckos. A bilateral ovariectomy was performed under general anesthesia in all five animals. The mass of the excised ovaries varied between 7 to 15 g (12.7\u201322.2% of body weight). One gecko died 1 d postsurgery; the four remaining animals were healthy 6 mon postsurgery. Gekkonids are unique among reptiles in that they undergo a monoautochronic ovulation (only one follicle is recruited by each ovary during each ovarian cycle); the presence of multiple vitellogenic follicles on each ovary facilitates the diagnosis of follicular stasis. This condition was present in all five geckos and was suspected to have led to ovarian torsion. This case series emphasizes the value of ultrasound examination for antemortem diagnosis of reproductive disorders in reptiles.<\/jats:p>","DOI":"10.1638\/2024-0022","type":"journal-article","created":{"date-parts":[[2024,9,5]],"date-time":"2024-09-05T05:55:11Z","timestamp":1725515711000},"page":"810-818","source":"Crossref","is-referenced-by-count":3,"title":["UNILATERAL OVARIAN TORSION IN FIVE GECKOS: CLINICAL AND ULTRASOUND FINDINGS"],"prefix":"10.1638","volume":"55","author":[{"given":"Cl\u00e9ment","family":"Paillusseau","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fr\u00e9d\u00e9ric","family":"Gandar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Camille","family":"Francois","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lionel","family":"Schilliger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1213","reference":[{"key":"9","doi-asserted-by":"crossref","unstructured":"KA Gustavsen, AB Saunders, BD Young, et al.  \"J Vet Cardiol.\"  16, \"Echocardiographic and radiographic findings in a cohort of healthy adult green iguanas (Iguana iguana).\" 185 (2014)","DOI":"10.1016\/j.jvc.2014.05.002"},{"key":"1","doi-asserted-by":"crossref","unstructured":"S Barten  and S Simpson  \"Mader's reptile and amphibian medicine and surgery.\"  \"Lizards.\" 152 (2019)","DOI":"10.1016\/B978-0-323-48253-0.00021-0"},{"key":"2","doi-asserted-by":"crossref","unstructured":"T Bays  and L de Sousa Dantas  \"Mader's reptile and amphibian medicine and surgery.\"  \"Clinical behavioral medicine.\" 922 (2019)","DOI":"10.1016\/B978-0-323-48253-0.00083-0"},{"key":"3","doi-asserted-by":"crossref","unstructured":"DS Bucy, DSM Guzman, AL Zwingenberger,  \"J Am Vet Med Assoc.\"  246, \"Ultrasonographic anatomy of bearded dragons (Pogona vitticeps).\" 868 (2015)","DOI":"10.2460\/javma.246.8.868"},{"key":"4","doi-asserted-by":"crossref","unstructured":"P Cigler, E Dervas, H Richter, et al.  \"J Zoo Wildl Med.\"  54, \"Ultrasonographic and computed tomographic characteristics of the reproductive cycle in the female veiled chameleons (Chamaeleo calyptratus).\" 231 (2023)","DOI":"10.1638\/2022-0052"},{"key":"7","doi-asserted-by":"crossref","unstructured":"M Germain, T Rarick, E Robins,  \"Obstet Gynecol.\"  88, \"Management of intermittent ovarian torsion by laparoscopic oophoropexy.\" 715 (1996)","DOI":"10.1016\/0029-7844(96)00096-8"},{"key":"10","doi-asserted-by":"crossref","unstructured":"G.
