The membranous portion of the urethra is completely surrounded by the fibers of the Sphincter urethræ membranaceæ. In front of it the deep dorsal vein of the penis enters the pelvis between the transverse ligament of the pelvis and the arcuate pubic ligament; on either side near its ter...
It is traversed by the prostatic part of the urethra and by the ejaculatory ducts, which divide the small median lobe from the rest of the gland. Its venous drainage passes to the vertebral venous veins (Bateson's). The male urethra is divided into prostatic, membraneous and spongy, or ...

In the 19 MUT adult male examined, 15 (15/19 = 79%) had clearly visible "knots" at the junctions of vas deferens and urethra (Fig. 6c,d), and the other four (4/19 = 21%) had small "knots" that can be identified with bright light under a dissecting scope (...
Human reproductive system - Male Anatomy, Hormones, Reproduction: The male gonads are the testes; they are the source of spermatozoa and also of male sex hormones called androgens. The other genital organs are the epididymides; the ductus, or vasa, defer
