This is a very specific question about testicles but is the top part (the part attached to sperm cords and epididymis)supposed to be slightly larger?

Here are some ...: The shape of epididymis usually resembles the figure of scribbling a low-case "r" with its head (globus majora) bigger at the the top of testis and its tapering body (shaft) and tail (globus minor) looped together with the curved part of vas deferens to hug onto the posterior superior aspect of corresponding testis. The epididymis is about 2.5 x 0.5 x 0.5 cm, yet with wide anatomical variation.
