Fertilization success is then influenced by characteristics of oocytes or sperm. In this study, we evaluated oocyte morphology and sperm motility parameters and their effects on the inseminating dose in a teleost fish Astyanax altiparanae . Interestingly, we found one of the lowest yet described inseminating doses in teleosts (2390 spermatozoa oocyte \u207b\u00b9 ml \u207b\u00b9 ). Such a fertilization efficacy may be explained by the long duration of sperm motility (&gt;75 s), the small oocyte diameter (695.119 \u00b5m), large micropyle diameter (7.57 \u00b5m), and the presence of grooves on the oocyte surface that guides spermatozoon to the fertilization area. Additionally, we have described for the first time a structure that combines grooves on the chorion surface and a ridge in the micropylar area.<\/p>\n<p>DOI: 10.1017\/S0967199417000624<\/p>\n<p>Full article <a href=\"https:\/\/www.researchgate.net\/publication\/321441246_Grooves_surrounding_the_micropyle_decrease_the_inseminating_dose_in_fish\" target=\"_blank\" rel=\"noopener\">here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Grooves surrounding the micropyle decrease the inseminating dose in fish Matheus Pereira-Santos, Eduardo Shimoda, Andr\u00e9 Furugen Cesar de Andrade, Luciano Andrade Silva, Takafumi Fujimoto, Jos\u00e9 Augusto Senhorini, George Shigueki Yasui and Laura Satiko Okada Nakaghi Aquaculture Center, S\u00e3o Paulo State University, Jaboticabal-SP, Brazil; Department of Pharmacy, C\u00e2ndido Mendes University, Campos dos Goytacazes, Brazil; Department of <a href=\"https:\/\/www.micropticsl.com\/es\/faq-items\/grooves-surrounding-the-micropyle-decrease-the-inseminating-dose-in-fish\/\"> [&#8230;]<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"menu_order":0,"comment_status":"open","ping_status":"closed","template":"","format":"standard","meta":{"footnotes":""},"faq_category":[148,217],"class_list":["post-29476","avada_faq","type-avada_faq","status-publish","format-standard","hentry","faq_category-animal-es","faq_category-fish-es"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.8 -
