Sexual function Flashcards
barriers affecting sexual function
genital function motor abilities sensation ROM muscle tone pre-existing attitudes (religion)
Masters and Johnson framework
arousal
plateau
orgasm
resolution
male sexual function
based on questionnaires
neural control of erections involves 2 regions of SC and higher centers in brain (T11-L2 and S2-S4)
can be generated in 2 ways- psychological arousal and sensory stimulation
reflexogenic erection
reflex arc intact
sensory stim from genital area, rectum or bladder travels to S2-S4 causing firing of parasympathetic efferents
psychogenic erection
psychological stimulation
sympathetic efferents from Tll-L2 or impules from higher centers cause sacral efferents to fire
smell, visual, erotic talk
level of injury guidelines for genital arousal
above T11= can only have reflexogenic
between T11 and L2= psychogenic and reflexogenic
low lesions= only psychogenic
Summary of genital function
most men retain capacity to have erection
loss of input from either center alters quality and/or ability to sustain
ejaculation
normally involves both thoracolumbar and sacral regions, plus supraspinal centers; damage to any center makes chance remote
32% incomplete UMN, 70% incomplete LMN
may have retrograde ejaculation
retrograde ejaculation
semen goes back up in bladder; not harmful
tx of ED
meds or injections- viagra
vacuum device- you have 30 min
penile implant
women genital function
neural control comparable to male response
erection vs vaginal lubrication and vasocongestion of genitalia- response different
not as much info about female sexuality
Orgasm
not totally dependent on genital sensation- 52% incomplete reach orgasm through fantasy, erotic imagery or stim of areas above LOL
some with complete injuries experience orgasm
reported as satisfying with resolution of sexual tension
fertility- men
men with SCI have low sperm count, impaired quality
slight chance of natural fertilization
sperm can be harvested through vibroejaculation, electroejaculation or surgery
electroejaculation
most common way to get sperm from man
under anesthesia, successful, concern of autonomic dysreflexia
fertility- women
menstrual cycle may be absent up to a year
