Cancer Spectrum: Medline Abstract In a longitudinal study measuring self-report, behavioral, and nocturnal penile tumescence variables before and after treatment with cognitive behavior therapy in an unmedicated sample of 40 outpatient depressed men, we found, contrary to expectation, that sexual activity per se was not reduced during the depressed state. Nocturnal penile tumescence alterations in depression may thus be similar to other persistent electroencephalographic sleep abnormalities seen in depressed patients in remission, in being more trait-like than statelike. Also, contrary to expectation, nocturnal penile tumescence abnormalities in depressed men did not reverse when measured in early remission, nor did nocturnal penile tumescence measures correlate significantly with behavioral measures of sexual function. jncicancerspectrum.oxfordjournals.org /cgi/medline/pmid;8422218   (331 words)

Susan's Place Transgender Resources for Transsexuals and Crossdressers: Library: Effects of Estrogen Treatment on Sexual Behavior in Male-to-Female Transsexuals: Experimental and Clinical Observations We recently showed that testosterone stimulates nocturnal penile tumescence in hypogonadal men in addition to increasing sexual activity and spontaneous erections, but erections elicited in the laboratory during psychophysiological testing were not affected by hypogonadism or testosterone treatment (Kwan et al., 1983). Nocturnal penile tumescence was measured using home monitors in order to estimate estrogen-induced changes in erectile capacity. Relationships between free testosterone level and nocturnal penile tumescence (% of sleep time in maximum erection x degree of tumescence, see Methods) throughout the various periods of observation during the study. www.susans.org /reference/estroeff.html   (3394 words)

Life Extension Newsletter: April 19, 2004 Prostate-specific antigen, prostate volume, nocturnal penile tumescence, total and free testosterone, prolactin, luteinizing hormone, erectile function scores, depression, fatigue and other parameters were assessed before treatment, at three months, and after the treatment period. Erectile function, sexual desire, sexual satisfaction and nocturnal penile tumescence increased over the course of the study in the group receiving testosterone as well as the group receiving carnitine. Erectile function and nocturnal penile tumescence were significantly more improved in this group than in those receiving testosterone. www.lef.org /newsletter/2004/2004_04_19.htm   (847 words)

August 1, 1997 Nocturnal penile tumescence testing with the RigiScan at 4-6 months in 2 patients demonstrated erections that approach minimal criteria for normalcy. To confirm the findings of this report, we are continuing to monitor the erectile function with interviews, validated questionnaires, and nocturnal penile tumescence testing in patients with bilateral nerve resection and grafts. Using electrical stimulation with resultant tumescence as criteria, these investigators found return of potency in 50-58% of rats, in comparison to 5-11% for the nerve ablated group at 2 and 4 months, respectively. www.infertility-male.com /erectdys/graft.htm   (3876 words)

Tests for Erection Problems Additional testing for erection problems may include a nocturnal penile tumescence (NPT) test or an intracavernosal injection test.

Erectile dysfunction and ... This study evaluates the sensitivity and specificity of decreased nocturnal tumescence in evaluating autonomic dysfunction in diabetic patients with erectile dysfunction and normal penile blood flow. Variations in nocturnal tumescence in association with REM sleep remain the most appropriate testing modality for diabetic erectile dysfunction as opposed to causes of non-organic origin. examines whether the Rigiscan device for measuring nocturnal tumescence can detect parasympathetic cardiovascular dysfunction in diabetic men with erectile dysfunction.The cause of erectile dysfunction in the two groups studied was not stated and other parameters such as androgen levels were not given. www.medforum.nl /idm/erectile.htm   (397 words)

American Family Physician: Penile tumescence studies in diabetic men - Tips from Other Journals An episode of nocturnal penile tumescence was defined as an abrupt increase in penile base circumference that corresponded with a 3-mm or greater change in pen deflection that was maintained for at least five minutes. Nocturnal penile tumescence studies are commonly used to assess sexual dysfunction in diabetic men. On the third night, patients were awakened at the point of maximal tumescence, and fullness of erection was estimated and penile buckling force was measured. www.findarticles.com /p/articles/mi_m3225/is_n5_v45/ai_12199686   (508 words)

Male Reproductive Clinic - Texas, Infertility - Infertility Encyclopedia If there is still doubt about a man's neurological status, the physician may perform the nocturnal penile tumescence test (NPT). A strain gauge device is used to measure normal tumescence (swelling) and rigidity of the individual's penis during sleep. In general, vascular (blood vessel-related) impotence is unlikely if there is normal tumescence and rigidity during sleep. urologychannel.com /whfc/infertility.shtml   (2733 words)

Disruption of the young-adult synchrony between luteinizing hormone release and oscillations in follicle-stimulating hormone, prolactin, and nocturnal penile tumescence (NPT) in healthy older men. We suggest that abrogation of joint synchrony among hypothalamically directed pituitary hormones and a neurogenically organized sexual response (nocturnal penile tumescence) can be unified thematically under an hypothesis of disrupted central nervous system hypothalamo-pituitary network coordination in human aging. Such implicit disarray of multinodal communication is of consequence both scientifically and clinically, especially in proposing aging theories and intervention strategies. Among one-variable results, only ApEn of LH release was significantly higher in older individuals at 1.323 +/- 0.058 vs. 0.897 +/- 0.089 in younger subjects (P = 0.0019), signifying greater disorderliness of the LH secretory process in aged men. www.arclab.org /medlineupdates/abstract_10522986.html   (510 words)
