释义 |
Anejaculation is the pathological inability to ejaculate in males, with (orgasmic) or without (anorgasmic) orgasm. Causes
It can depend on one or more of several causes, including:
Anejaculation, especially the orgasmic variant, is usually indistinguishable from retrograde ejaculation. However, a negative urinalysis measuring no abnormal presence of spermatozoa in the urine will eliminate a retrograde ejaculation diagnosis. Thus, if the affected person has the sensations and involuntary muscle-contractions of an orgasm but no or very low-volume semen, ejaculatory duct obstruction is another possible underlying pathology of anejaculation. ManagementAnejaculation in spinal cord injury{{see|Sexuality after spinal cord injury#Ejaculation and male fertility}}The first-line method for sperm retrieval in men with spinal cord injury is penile vibratory stimulation (PVS).[1] The penile vibratory stimulator is a plier-like device that is placed around the glans penis to stimulate it by vibration. In case of failure with PVS, spermatozoa are sometimes collected by electroejaculation, or surgically by per cutaneous epididymal sperm aspiration (PESA) or testicular sperm extraction (TESE).[1] Notes1. ^1 2 {{Cite journal | last1 = Chehensse | first1 = C. | last2 = Bahrami | first2 = S. | last3 = Denys | first3 = P. | last4 = Clément | first4 = P. | last5 = Bernabé | first5 = J. | last6 = Giuliano | first6 = F. | doi = 10.1093/humupd/dmt029 | title = The spinal control of ejaculation revisited: A systematic review and meta-analysis of anejaculation in spinal cord injured patients | journal = Human Reproduction Update | volume = 19 | issue = 5 | pages = 507–526 | year = 2013 | pmid = 23820516| pmc = }} 2. ^ {{Webarchive|url=https://web.archive.org/web/20080208145058/http://www.giovannialei.it/patologie/eiaculazione_retrograda.htm |date=2008-02-08 }} {{it icon}} and {{it icon}} 2 : Male genital disorders|Ejaculation |
