The corpus spongiosum is the mass of spongy tissue surrounding the male urethra within the penis. [1] It is also called the corpus cavernosum urethrae in older texts.
Glans insufficiency syndrome, also known as soft glans, cold glans, or glans insufficiency, is a medical condition that affects male individuals.This condition is characterized by the persistent inability of the glans penis to achieve and maintain an erect or turgid state during sexual arousal, remaining soft and cold.
It is the expanded cap of the corpus spongiosum, [10] a sponge-like region that surrounds the male urethra within the penis maintaining it as a viable channel for ejaculation. [11] The glans is covered by a stratified squamous epithelium and a dense layer of connective tissue equivalent to the dermis of typical skin. [ 12 ]
The proximal parts of the corpus spongiosum form the bulb and the distal ends form the glans penis. [5] The enlarged and bulbous-shaped end of the corpus spongiosum forms the glans penis with two specific types of sinusoids, which supports the foreskin, a loose fold of skin that in adults can retract to expose the glans.

The spongy urethra (cavernous portion of urethra, penile urethra) is the longest part of the male urethra, and is contained in the corpus spongiosum of the penis.. It is about 15 cm long, and extends from the termination of the membranous portion to the external urethral orifice.
Erectile tissue is tissue in the body with numerous vascular spaces, or cavernous tissue, that may become engorged with blood. [1] [2] However, tissue that is devoid of or otherwise lacking erectile tissue (such as the labia minora, vestibule, vagina and urethra) may also be described as engorging with blood, often with regard to sexual arousal.
The corpus spongiosum, a ventral, medial body that is more echoic than the corpora cavernosa, is also covered by the tunica albuginea and contains the urethra. As can be seen in Figures 1 and 2, it is more dilated and prominent in its proximal segment, known as the bulb, and in its distal segment, constituting the glans.
In human male anatomy, the radix (/ r eɪ. d ɪ k s /) [1] or root of the penis is the internal and most proximal portion of the human penis that lies in the perineum.Unlike the pendulous body of the penis, which is suspended from the pubic symphysis, the root is attached to the pubic arch of the pelvis and is not visible externally.
