“…Significant research attention has been focused on documenting and analysing sperm morphometry in several species such as fox (Soler, Contell, et al, 2017), boar (Barquero, Soler, et al, 2021), dairy cattle (Valverde et al, 2016), alpaca (Cucho et al, 2019), llama (Cucho, Gallegos, et al, 2021), dog (Soler, Alambiaga, et al, 2017) and vicuña (Cucho, Puelles, et al, 2021). It has been reported that relevant variability exists in sperm morphometry among males from the same population (Górski, Kondracki, Strachocka, & Wysokińska, 2017; Górski, Kondracki, & Wysokińska, 2017; Morrow & Gage, 2001) and individual variation within males has also been more recently reported (Maroto‐Morales et al, 2012; Ros‐Santaella et al, 2015).…”
