do astartes have testicles?

given that they all come from human stock i would think they do, but does the process of becoming an astartes remove them or withdraw them into the pelvic cavity?

i imagine testosterone is a significant part of astartes biology, but couldn't it maybe be produced by one/some of the genetic reconfigurations?

i ask this because i've never heard of astartes having sexual desire and for the simple fact that external testicles are a serious weak point for superhuman soldiers. i don't care if they are astartes, primarch or the emperor himself - a strike to this most sensitve of regions will have any male on his knees X0
