TY - JOUR A1 - , T1 - Lizard testis volume measurements: Are they always underpinned by the correct assumptions? JO - Eur. J. Anat. SN - 1136-4890 Y1 - 2007 VL - 11 SP - 163 EP - 167 UR - http://www.eurjanat.com/web/paper.php?id=07030163 KW - article KW - information center KW - lizard KW - male KW - nonhuman KW - pogona barbata KW - testis size N2 - Two basic assumptions are frequently used in the measurement of testis volume: 1) they are highly conserved and thus measures are frequently restricted to a measure of a single testis/individual, and 2) a prolate spheroid provides an adequate measure of volume. Based on the measurement of museum and road kill Pogona barbata (Eastern bearded dragon), we showed these assumptions did not hold and recommend that when considering testis volume, researchers measure both testes and the formula used should be informed by careful consideration of their shape.
