Sexual dysfunctions are multifactorial and can be caused by a variety of physiological and biological factors like hormonal, neurological and vascular discrepancies.
Premature ejaculation is defined as a male sexual dysfunction where ejaculation occurs prior to or within 1 min of penetration, inability to delay ejaculation on all or nearly all penetrations and negative personal consequences such as distress, frustration and avoidance of sexual intercourse.
The mechanism of ejaculation reflects a muscular event that occurs via simultaneous contraction of the smooth muscles of the prostate gland, smooth muscles of the bladder neck and relaxation of the muscles of the urethral sphincter. Seminal fluid is sucked into the posterior urethra (while relaxing during emission) and ejected into the bulbous urethra upon contraction during ejaculation. Involuntary contraction of the Bulbospongiosus muscle expels contents from the urethra during ejaculation.
Pelvic floor therapy has been shown to improve control over ejaculatory delay and allow significant increase in intravaginal/intrarectal ejaculatory latency times in men with pelvic floor muscle dysfunction. Strong Bulbospongiosus contractions may enhance and intensify orgasmic pleasures during ejaculations.
Behavioural therapies such as squeeze technique and internal squeeze will also be of help. The squeeze technique makes use of the bulbospongiosus reflex in which sustained pressure is applied to the glans of the penis causing contraction of the Bulobospongiosus muscle to diminish the ejaculatory reflex. Stopping the motion of intercourse and performing a sustained contraction of the pelvic floor muscles can also defer the urgency to ejaculate. (Internal squeeze without manual pressure).
