NCBI ROFL: Pleasure and pain: the effect of (almost) having an orgasm on genital and nongenital sensitivity.

If you want to do a scientific study of sexual function (in this case, how orgasm changes genital sensitivity), it’s usually necessary to perform it under carefully controlled conditions. So how do you do that in the context of studying female orgasms? Check out the [probably NSFW] description below.

The effect of sexual arousal and orgasm on genital sensitivity has received little research attention, and no study has assessed sensation pleasurableness as well as painfulness.
To clarify the relationship between sexual arousal, orgasm, and sensitivity in a healthy female sample. Read More

NCBI ROFL: What makes a sexy leg sexy?

The Benslimane’s Artistic Model for Leg Beauty.

“BACKGROUND: In 2000, the author started observing legs considered to be attractive. The goal was to have an ideal aesthetic model and compare the disparity between this model and a patient’s reality. This could prove helpful during leg sculpturing to get closer to this ideal. Postoperatively, the result could then be compared to the ideal curves of the model legs and any remaining deviations from the ideal curves could be pointed out and eventually corrected in a second session. The lack of anthropometric studies of legs from the knee to the ankle led the author to select and study attractive legs to find out the common denominators of their beauty.
METHOD: The study consisted in analyzing the features that make legs look attractive. Read More

NCBI ROFL: Breasts don’t just bounce. They do figure-eights.

Breast displacement in three dimensions during the walking and running gait cycles.

“This study aimed to assess the trajectory of breast displacement in 3 dimensions during walking and running gait, as this may improve bra design and has yet to be reported. Fifteen D-cup participants had reflective markers attached to their nipples and trunk to monitor absolute and relative breast displacement during treadmill walking (5 kph) and running (10 kph).

NCBI ROFL: Finally, science weighs in: should you give it up on the first date?

Differing Relationship Outcomes When Sex Happens Before, On, or After First Dates.

“While recent studies have suggested that the timing of sexual initiation within a couple’s romantic relationship has important associations with later relationship success, few studies have examined how such timing is associated with relationship quality among unmarried couples. Using a sample of 10,932 individuals in unmarried, romantic relationships, we examined how four sexual-timing patterns (i.e., having sex prior to dating, initiating sex on the first date or shortly after, having sex after a few weeks of dating, and sexual abstinence) were associated with relationship satisfaction, stability, and communication in dating relationships.

NCBI ROFL: How is a woman’s breast like a pork roast? (hint: it involves pimento olives).

Ultrasound-guided breast biopsy for surgical residents: evaluation of a phantom model.

Ultrasound is increasingly used by surgeons for evaluation of breast lesions. While surgical residents have sufficient exposure to breast surgery, many lack exposure to office-based procedures, such as ultrasound-guided breast biopsy. A phantom model was created to teach surgical residents basic breast ultrasound and biopsy skills and to evaluate the resident’s response when incorporated into the curriculum.
The model was created using a pork roast and 10 variably-sized pimento olives. Twenty-four surgical residents were given a brief introduction to breast ultrasound followed by up to 5 minutes to ultrasound the model and note the embedded lesions. The number and location of lesions found and the time spent per resident were recorded. Residents were then introduced to the vacuum-assisted core biopsy system and observed performing ultrasound-guided biopsies. Pre- and postsession evaluations were completed by all residents. Scatterplot regression models were used for data analysis. Read More

NCBI ROFL: And… we’re back! With humping hamsters!

Characteristics of the motor and genital copulatory responses of the male hamster.

“The temporal and dynamic characteristics (duration, frequency, rhythmicity, and vigor) of pelvic thrusting displayed by 17 male golden hamsters during their copulatory behavioral responses: mounts, intromissions, ejaculations, and long intromissions, as well as their temporal correlation with the genital contacts established by intravaginal penile insertion, were studied by an accelerometric and polygraphic technique.

NCBI ROFL: Large penises and an evolutionary theory of vaginal orgasm.

By ncbi rofl | October 12, 2012 7:00 pm

Women Who Prefer Longer Penises Are More Likely to Have Vaginal Orgasms (but Not Clitoral Orgasms): Implications for an Evolutionary Theory of Vaginal Orgasm.

“Introduction.  Research indicates that (i) women’s orgasm during penile-vaginal intercourse (PVI) is influenced by fitness-related male partner characteristics, (ii) penis size is important for many women, and (iii) preference for a longer penis is associated with greater vaginal orgasm consistency (triggered by PVI without concurrent clitoral masturbation). Aims.  To test the hypothesis that vaginal orgasm frequency is associated with women’s reporting that a longer than average penis is more likely to provoke their PVI orgasm. Method.  Three hundred twenty-three women reported in an online survey their past month frequency of various sexual behaviors (including PVI, vaginal orgasm, and clitoral orgasm), the effects of a longer than average penis on likelihood of orgasm from PVI, and the importance they attributed to PVI and to noncoital sex.

Feelings of Disgust and Disgust-Induced Avoidance Weaken following Induced Sexual Arousal in Women

“Sex and disgust are basic, evolutionary relevant functions that are often construed as paradoxical. In general the stimuli involved in sexual encounters are, at least out of context strongly perceived to hold high disgust qualities. Saliva, sweat, semen and body odours are among the strongest disgust elicitors. This results in the intriguing question of how people succeed in having pleasurable sex at all. One possible explanation could be that sexual engagement temporarily reduces the disgust eliciting properties of particular stimuli or that sexual engagement might weaken the hesitation to actually approach these stimuli.

Participants were healthy women (n = 90) randomly allocated to one of three groups: the sexual arousal, the non-sexual positive arousal, or the neutral control group. Film clips were used to elicit the relevant mood state. Participants engaged in 16 behavioural tasks, involving sex related (e.g., lubricate the vibrator) and non-sex related (e.g., take a sip of juice with a large insect in the cup) stimuli, to measure the impact of sexual arousal on feelings of disgust and actual avoidance behaviour.

NCBI ROFL: "Say it…near the flower shop": further evidence of the effect of flowers on mating.

“For millennia, flowers have been used to convey romance. In this study, 18-25-year-old women (N = 600) walking alone in a shopping mall were approached by an attractive 20-year-old male-confederate who solicited them for their phone number. Read More

NCBI ROFL: Could watching porn before working out improve men's weightlifting performance?

Changes in salivary testosterone concentrations and subsequent voluntary squat performance following the presentation of short video clips.

“Previous studies have shown that visual images can produce rapid changes in testosterone concentrations. We explored the acute effects of video clips on salivary testosterone and cortisol concentrations and subsequent voluntary squat performance in highly trained male athletes (n=12). Saliva samples were collected on 6 occasions immediately before and 15 min after watching a brief video clip (approximately 4 min in duration) on a computer screen. The watching of a sad, erotic, aggressive, training motivational, humorous or a neutral control clip was randomised. Subjects then performed a squat workout aimed at producing a 3 repetition maximum (3RM) lift. Read More
