GENERAL INFORMATION
The transversus perinei profundus is a muscle located in the perineum. It is part of the deep layer of the pelvic floor muscles and plays a role in supporting pelvic organs as well as maintaining continence.
ORIGIN
This muscle originates from the ischial ramus.
INSERTION POINT
It inserts into the central tendon of the perineum.
MAJOR ARTERIES
The transversus perinei profundus receives its blood supply from branches of the internal pudendal artery.
NEURAL INNERVATION
This muscle is innervated by the pudendal nerve (S2-S4), which provides sensory and motor innervation to the perineum.
TRIGGER POINT
Trigger points in the transversus perinei profundus muscle can cause pain and discomfort in the perineal region.
CONCENTRIC FUNCTION
During contraction, the transversus perinei profundus muscle assists in maintaining pelvic floor tone and contributes to supporting pelvic organs.
ECCENTRIC FUNCTION
The eccentric function of this muscle occurs during relaxation. It allows for the relaxation of the pelvic floor muscles and the release of tension in the perineum.
ISOMETRIC FUNCTION
This muscle can contract isometrically to provide stability and support to the perineum and pelvic floor muscles.

ANTAGONIST MUSCLES
- Bulbospongiosus: Helps expel the last drops of urine in males and contributes to erection and ejaculation.
- Ischiocavernosus: Assists in maintaining erection by compressing the veins of the penis or clitoris.
COMMON INJURIES
- Perineal tears during childbirth: Tears in the perineum that can damage the muscle.

STRETCHES
- Butterfly stretch: Stretches the inner thighs and perineal muscles, enhancing flexibility.
- Happy baby pose: Releases tension in the perineum and lower back, promoting relaxation.
- Seated forward fold: Stretches the hamstrings and perineal area, relieving tension.
- Child’s pose: Stretches the perineum and relaxes the pelvic floor muscles, aiding in overall muscle relaxation.
