Premature ejaculation is a part of which phase of
sexual disorders?
a) Excitement phase
b) Plateau phase
c) Orgasm phase
d) Refractory phase
Correct Answer - C
Ans. C. Orgasm phase
The male sexual response is described as a sequence of phases
including 4 stages: sexual desire, arousal, orgasm (ejaculation) and
resolution.
The male sexual dysfunction usually occurs in one or more of
the three first stages of the sexual response cycle, including:
Dysfunctions of sexual desire (e.g. hypoactive sexual desire)
Arousal (e.g. erectile dysfunction)
Orgasm/ejaculation (e.g. premature ejaculation, retarded ejaculation
or inability to ejaculate).
Premature ejaculation occurs due to the rapid evolution of the two
first stages of the sexual response cycle and is not necessarily
related to strong sexual arousal or changes in erection.
Premature Ejaculation seems to be a neurobiological problem that is
related to low serotonin levels in those regions of the central nervous
system that regulate ejaculation (brain and spinal cord).
