The use of anogenital distance as a non‐invasive predictor of seminal quality in captive squirrel monkey (Saimiri collinsi Osgood 1961)

Background Anogenital distance is considered a non‐invasive measure to assess the development and functionality of sexual organs in different animal species. Hence, this measurement could potentially be used during the selection of non‐human primates for reproductive biotechnology programs. The aim...

Description
Summary:Background Anogenital distance is considered a non‐invasive measure to assess the development and functionality of sexual organs in different animal species. Hence, this measurement could potentially be used during the selection of non‐human primates for reproductive biotechnology programs. The aim of this study was to assess the correlation between anogenital distance and reproductive parameters in captive Saimiri collinsi. Methods Eight mature S. collinsi males were evaluated. Body weight, reproductive hormone levels, testicular volume, and seminal parameters were determined, and their relationship with anogenital distance measurements was assessed. Results Anogenital distance was correlated with seminal volume, sperm motility, vigor, and plasma membrane integrity, but not with body weight, reproductive hormones, and testicular volume. Conclusion The determination of anogenital distance is a non‐invasive method to predict seminal quality. This procedure has the advantage of providing andrologic information without a negative impact on animal welfare.
