Summary
Male pelvic floor muscle dysfunction is common, even in men without symptoms. The puborectal muscle (PRM) shows higher dysfunction rates than the external anal sphincter (EAS). Further research is needed for pelvic floor symptoms (PFS) in men.
Area of Science:
- Urology
- Men's Health
- Pelvic Floor Disorders
Background:
- Pelvic floor symptoms (PFS) like urinary, defecation, sexual, and pain issues are common in men.
- Assessing external anal sphincter (EAS) and puborectal muscle (PRM) function is crucial for understanding male pelvic floor dysfunction.
Purpose of the Study:
- To investigate associations within and between EAS and PRM muscle function.
- To explore the relationship between muscle (dys)function and the number of male PFS.
Main Methods:
- Cross-sectional study of men aged ≥21 with 0-4 symptoms.
- Utilized digital pelvic floor assessments for EAS and PRM.
- Analyzed muscle function agreement, associations, and links to PFS using statistical and visual methods.
Main Results:
- 21% of men had normal muscle function; 33.2% reported no symptoms, yet 80% of those had muscle dysfunction.
- No clear dose-response link between muscle dysfunction and symptom count.
- Puborectal muscle (PRM) exhibited greater and more severe dysfunction than the external anal sphincter (EAS).
Conclusions:
- Absence of PFS does not guarantee normal pelvic floor muscle function.
- Significant muscle dysfunction exists, particularly in the PRM.
- Further research on male pelvic floor muscles and PFS is warranted.

01:26Muscles of the Pelvic Floor and Perineum
2.0K
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....

01:19Urodynamic Studies: Uroflowmetry
431
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

01:23Urinary Bladder
1.4K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

01:28Menopause
246
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...
