Anatomy

Body (shaft)
Suspended from the pubic symphysis and located between the root and the glands, this is the free part of the penis. Composed of three cylinders of erectile tissue.

Epithelium
Refers to the shaft skin, the prepuce, and the preputial mucosa.

Erectile Tissues
Contained in the root and the body, erectile tissues fill with blood during sexual arousal, producing an erection.

Glans
Conical in shape and the most distal part of the penis, this part contains the opening of the urethra.
The urethral opening is where urine and semen can exit via urination and ejaculation respectively.

Prepuce (foreskin)
A double layer of skin located at the neck of the glands. It typically covers the glands. The frenulum (a fold of skin) connects the prepuce to the surface of the glands).
This covers/protects the glands & body

Root
Not visible externally, the root is the most proximal, fixed part of the penis. It is located in the superficial perineal pouch of the pelvic floor.
The root contains three erectile tissues, and four muscles. The erectile tissues are known as the left and right crura, and the bulb of the penis. The muscles are known as the bulbospongiosus and the ischiocavernosus (of which there are 2 of each).
The root is supported by 2 ligaments, the suspensory ligament and the fundiform ligament.

Interaction with HRT

When taking FHT it is important to note that it will have some effect on the penis. It will cause some shrinkage in size. Taking these hormones will also result in decreased spontaneous erections; and erections in general.

When taking MRT it is important to note that it will have some effect on the clit. It will cause growth in size and result in wha is essentially a micropenis.
