**1. Introduction**

The pelvis contains organs such as the bladder, prostate, (uterus in women), and rectum, and the pelvic floor muscles are the underlying muscles. The pelvic floor muscles wrap around the pelvic bones and support several organs. Some pelvic floor muscles form a sling around the rectum for greater stability. The functioning of these pelvic floor muscles maintains urination, defecation, and sexual life. However, if the muscles at the bottom of the pelvis cannot be properly relaxed during urination or defecation, urinary incontinence, fecal incontinence, ED, and women will experience pain during sexual intercourse.

Pelvic bottom dysfunction (PFD) is a disease caused by damage, dysfunction, and degeneration of pelvic bottom supporting tissue, which is advocated by the International Urological Society (IUGA) and the International Continence Society (ICS). It mainly includes pelvic organ prolapse (POP), pelvic pain, sexual dysfunction, lower urinary tract (LUT) abnormality, and defecation dysfunction. The causes of such pelvic floor muscle dysfunction are not known at all, but aging, obesity, pregnancy, pelvic surgery, etc. are known as factors.

The first non-invasive treatment proposed for pelvic floor muscle dysfunction is pelvic floor muscle training (PFMT), but the results are inconsistent. Systematic review and meta-analysis of non-surgical treatments for urinary incontinence, examining combinations of five common interventions: PFMT, electrical stimulation (ES), vaginal cone (VC), bladder training (BT), and serotonin-noradrenaline reuptake inhibitors (SNRIs). This study reported that more intense PFMT was an effective treatment, but incontinence assessment methods and intervention protocols differed between studies, and further research is needed [1]. Given the difficulty and effectiveness of sustaining PFMT, new conservative therapies are needed to replace pelvic floor muscle training.

In recent years, the US Food and Drug Administration has approved magnetic stimulation as a new non-invasive treatment method for pelvic floor muscle dysfunction. Magnetic stimulation therapy is a method of non-invasively stimulating central nerves and peripheral nerves using electric current generated by magnetism. This method was previously used in the fields of neurology and orthopedics as transcranial magnetic stimulation and skeletal muscle magnetic stimulation, but in the field of urology, it is mainly used for the treatment of urinary incontinence. Furthermore, magnetic stimulation therapy has been found to be effective not only in urinary incontinence but also in a series of diseases related to the pelvic floor muscles.

This paper focuses on magnetic stimulation therapy and introduces various therapeutic effects on pelvic floor muscle disorders.
