The medical hazard, for him, of being beneath her

Tuesday, January 13th, 2015

“Safe sex” — in its most mechanical aspects — is the focus of this new study:

reisMechanisms Predisposing Penile Fracture and Long-Term Outcomes on Erectile and Voiding Functions,” Leonardo O. Reis [pictured here], Marcelo Cartapatti, Rafael Marmiroli, Eduardo Jeronimo de Oliveira Júnior, Ricardo Destro Saade, and Adriano Fregonesi, Advances in Urology, volume 2014, article ID 768158. The authors, at University of Campinas (UNICAMP) and Pontifical Catholic University of Campinas (PUC), Brazil, report:

PURPOSE. To determine the mechanisms predisposing penile fracture as well as the rate of long-term penile deformity and erectile and voiding functions….

Results. Among the 44 suspicious cases, 42 (95.4%) were confirmed, mean age was 34.5 years (range: 18–60), mean follow-up 59.3 months (range 9–155). Half presented the classical triad of audible crack, detumescence, and pain. Heterosexual intercourse was themost common cause (28 patients, 66.7%), followed by penile manipulation (6 patients, 14.3%), and homosexual intercourse (4 patients, 9.5%). “Woman on top” was the most common heterosexual position (𝑛 = 14, 50%), followed by “doggy style” (𝑛 = 8, 28.6%). Four patients (9.5%)maintained the cause unclear. Six (14.3%) patients had urethral injury and two (4.8%) had erectile dysfunction, treated by penile prosthesis and PDE-5i. No patient showed urethral fistula, voiding deterioration, penile nodule/curve or pain.

CONCLUSIONS. ‘Woman on top’ was the potentially riskiest sexual position (50%).

The Specter of the Specter of Internet Pornography

Thursday, January 8th, 2015

The dire, horrible, brain-damaging effects of pornography may not exactly exist, suggests this study of a study that insists that yes, those effects do exist. The studies are:

Neuroscience research fails to support claims that excessive pornography consumption causes brain damage,” Rory C. Reid, Bruce N. Carpenter, and Timothy W. Fong, Surgical Neurology International, 2011; 2: 64. The authors, at University of California, Los Angeles, and Brigham Young University, explain:

“In their editorial on excessive pornography use, Hilton and Watts [see the citation, below] offer some interesting neuroscience perspectives on their conceptualization of pornography problems as an addictive disorder. They highlight several parallels between dysregulated pornography consumption and other maladaptive behaviors, some of which are viewed as addictions. Although we believe these parallels are worthy of scientific inquiry, Hilton and Watts offered little, if any, convincing evidence to support their perspectives. Instead, excessive liberties and misleading interpretations of neuroscience research are used to assert that excessive pornography consumption causes brain damage. We wish to clarify what the research actually does suggest.”

Dr. Hilton earlier wrote a metaphor-packed expose called “Slave Master How Pornography Drugs & Changes Your Brain“, which was unleashed educationally on the readers, if there are any, of Salvo magazine. That same issue of Salvo includes a salvo about a porn star, attributed to the often-excited Dr. Judith Reisman, whose work we have appreciated time and again.

Squirting, Reviewed by Peering Physicians

Wednesday, December 24th, 2014

Six French doctors took a squinting look at whether and how seven women squirt. The doctors published this study explaining, to some extent, what they did and why they did it:

Nature and Origin of ‘Squirting’ in Female Sexuality,” Samuel Salama, Florence Boitrelle, Amélie Gauquelin, Lydia Malagrida, Nicolas Thiounn, and Pierre Desvaux, Journal of Sexual Medicine, epub December 24, 2014. (Thanks to investigator Ivan Oransky for bringing this to our attention.) The authors, at several institutions in France, write:

“METHODS: Seven women, without gynecologic abnormalities and who reported recurrent and massive fluid emission during sexual stimulation, underwent provoked sexual arousal. Pelvic ultrasound scans were performed after voluntary urination (US1), and during sexual stimulation just before (US2) and after (US3) squirting. Urea, creatinine, uric acid, and prostatic-specific antigen (PSA) concentrations were assessed in urinary samples before sexual stimulation (BSU) and after squirting (ASU), and squirting sample itself (S).

“CONCLUSIONS: The present data based on ultrasonographic bladder monitoring and biochemical analyses indicate that squirting is essentially the involuntary emission of urine during sexual activity, although a marginal contribution of prostatic secretions to the emitted fluid often exists.”

Here’s further detail from the study:

UPDATE (also December 24, 2014): An earlier, related study, with a self-explanatory title:

Endogenous female prostate-specific antigen from female ejaculate may confound the use of prostate-specific antigen as a biomarker of exposure to semen,” Gwinyai Masukume, Contraception, vol. 89, no. 1, 2014, pp. 68-69.

Study: Top (male) comedians die earlier?

Friday, December 12th, 2014

A new study from professors Simon Stewart and David Thompson of the Centre for the Heart and Mind and the Mary MacKillop Institute of Health Research (MMIHR) at the Australian Catholic University (ACU) has found that :

“Elite comedians are at increased risk of premature death compared to their less funny counterparts.”

The team examined a study cohort of 53 (exclusively male) comedians from the UK and Ireland – both living (23) and not (30) – and analysed the data using IBM SPPS Statistics version 22.0. The data were weighted according to the ‘funniness’ of the man in question, running from ‘relatively funny’ to ‘hilariously funny’.

Results:

“On an adjusted basis, there was no correlation between the decade of birth (HR 0.94, 95% 0.65 to 1.38 per incremental decade; p =0.763) and comedy team status (HR 1.13, 95% 0.51 to 2.48 versus independent comedian; p = 0.761) with longevity. However, an increasingly funny comedy score was associated with increased mortality (HR 1.24, 95% CI 1.06 to 1.44 per unit funny score; p = 0.006). Of the 23 comedians adjudged to be very funny (score 8–10), 18 (78%) had died versus 12 (40%) of the rest; mean age at death 63.3 ± 12.2 versus 72.3 ± 14.7 (p = 0.079). Within comedy teams, those identified as the funnier member(s) of the partnership were, on an adjusted basis, more than three times more likely to die prematurely when compared to their more serious comedy partners (HR 3.52, 95% CI 1.22, 10.1; p = 0.020).”

The hypothesis was further bolstered with the finding that in the case of double-acts, the ‘stooges’ (or straight men) were more than 3 times less likely to die on an adjusted basis before those designated as the funny man.

See: ‘Does comedy kill? A retrospective, longitudinal cohort, nested case–control study of humour and longevity in 53 British comedians’ in: The International Journal of Cardiology, 180 (2015), pp. 258–261.

Notes [1] : The paper cites this study from the British Journal of Psychiatry, 204 (2014), pp. 341–345, by Victoria Ando, Gordon Claridge and Ken Clark Psychotic traits in comedians. The researchers asked more than 500 comedians to complete an online form based on the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE), with scales measuring four dimensions of psychotic traits, finding that : “Comedians scored significantly above O-LIFE norms on all four scales.”

[2]: Sadly, both the comedians in the clip above – Peter Cook (comedy rating 9 in the ACU study) and Dudley Moore (comedy rating 5 in the ACU study) are no longer metabolically extant. They are deceased. They are ex-comedians. They do, however, in a sense, live on, in YouTubeLand

For fans of randomization: Effect of Vaginal Electrical Stimulation

Sunday, December 7th, 2014

If you find randomization to be stimulating, we suggest you read this study:

Effect of Vaginal Electrical Stimulation on Female Sexual Functions: A Randomized Study,” Serdar Aydın, Çağrı Arıoğlu Aydın, Gonca Batmaz and Ramazan Dansuk, The Journal of Sexual Medicine, epub December 3, 2014. The authors, at Bezmialem Vakif University and at Liv Hospital, Istanbul, Turkey, explain:

METHODS. Forty-two women… The probe was inserted, and a medium-frequency (50 Hz) alternating current was administered for a duty cycle of 5 seconds on followed by a 5-second rest.

CONCLUSIONS. The lack of significant difference… puts into question the effectiveness of electrical stimulation as a monotherapy…

Here’s further detail from the study:
