Male Sexual Dysfunction
Male sexual dysfunction refers to any difficulty/problem with the normal sexual function in a man which prevents him (or the couple) from experiencing sexual satisfaction. Amongst males, the prevalence of sexual dysfunction ranges from 10% to 50% (average 30%). The problem can be associated with any of the three major components of male sexual function namely libido, erection and ejaculation:
Libido: The sexual urge/desire may be reduced or absent altogether. This can present as lack of interest in sex, absent/reduced sexual thoughts, and poor response to erotic stimuli.
Problems with the libido could be due to low testosterone levels, poor general health, certain drugs (tricyclic antidepressants, antipsychotics, etc.), physical ailments (uremia, hypogonadism, high blood pressure, etc.), depression, anxiety, etc.
Erection: A problem in getting an erection or maintaining it sufficiently for sexual intercourse (at least 25% of times) is termed as erectile dysfunction (impotence). An occasional inability to maintain an erection is common and is a normal phenomenon. However, if this tends to persist, treatment must be sought. There can be many causes for erectile dysfunction (impotence) and it needs careful evaluation.
Ejaculation and orgasm: Problems with ejaculation include premature ejaculation (which occurs sooner than desired by the man or his partner), retarded / inhibited ejaculation (when ejaculation is slow to occur) or retrograde ejaculation (wherein the semen is ejaculated backwards into the urinary bladder).
The ejaculation generally coincides with orgasm (a highly pleasurable sensation experienced in the brain) in males. Abnormally, the orgasm may be absent (anorgasmia) and this also is a component of sexual dysfunction. Read more about Premature Ejaculation.
