This Sunday on the Discovery Channel, Park Slope Food Co-op worker Maggie Gyllenhaal will watch a lady have an orgasm with you. Gyllenhaal is hosting a new episode of the show Curiosity, where she'll try to better understand the female orgasm. Watch the clip below, where the actress actually says the words: "Inside this MRI machine, she's about to give herself an orgasm... in the name of science."

Introduction: This study examines the effectiveness of integrating mindfulness-based techniques within therapy for women suffering to achieve orgasm. Although widely applied in psychotherapy, this approach has only recently been introduced in the treatment of female sexual dysfunction.
Aim: To compare the effectiveness of a video-based self-administered treatment, rooted within the cognitive behavioral treatment (CBT) framework, with a video-based self-administered mindfulness treatment applying cognitive behavioral sexual therapy (mindfulness-based cognitive therapy), the latter of which was specifically created to increase women's ability to achieve orgasm.
Methods: A convenience sample of 65 women suffering from difficulties to achieve orgasm, aged 18 to 58 years (mean = 32.66, standard deviation = 9.48), were randomly allocated using a randomization procedure to either a mindfulness-based cognitive therapy (N = 35) or CBT (N = 30) group. Each participant completed questionnaires before and after the start of treatment and 2 months after its completion.
Results: Statistical analyses show that women in both groups presented increased sexual functioning (P = .001) and decreased sexual distress (P
Clinical implications: To the best of our knowledge, this is the first study to apply a randomized allocation procedure to evaluate the effectiveness of a video-based mindfulness intervention for women struggling to achieve orgasm. These results should guide clinicians' decisions with respect to evaluating the relevance and the real added value of proposing mindfulness exercises to their patients with such difficulties.
Conclusion: When women suffering from difficulties to achieve orgasm are randomly assigned to a mindfulness group or an active control, improvements in sexual functioning and reductions in sexual distress can be observed after both treatments.

Women can produce several types of fluid during sex. At the arousal stage, lubricating fluid is released by the vagina. Then, as orgasm is reached, two other types of fluid can sometimes be expelled from the urethra: a milky fluid secreted in small amounts, and a clear fluid released in large volumes, often hundreds of millilitres.
To find out for sure, Miyabi Inoue, a urologist at Miyabi Urogyne Clinic in Japan, and her colleagues injected blue dye mixed with water into the bladders of five female volunteers who could squirt. A male volunteer then sexually stimulated the women until they squirted and a researcher caught the ejected liquid in a sterile cup.
The squirted liquid from four of the women in the study was found to contain PSA, suggesting they produced female ejaculate around the same time as they squirted urine, and the two fluids mixed together in the urethra.
Welcome to GirlCum - The series where girl's sexual satisfaction is as important as male's cumshot. Watch the most spectacular multiple orgasms of the world's best-known actresses in stunning 4K quality videos. These girls are wild and they desperately need to cum. Can we keep up with them while their female jizz and squirts are flying around? You bet! Each scene contains 5+ climax moments and female juices all over the place (literally!)
GirlCum.Video is the only place in the whole porn web where you can witness your favorite porn actresses actually CUM. While we focus on the hardcore action itself, uncontrolled multiple orgasms happen with each girl in each episode. Not once, not twice but these girls are actually climaxing 5+ times in a single video! How they achieve that? They use their hands, toys and of course male talents - every method is permitted and the utter orgrasmic mess in a scene is a must.
Oxygen utilization levels are displayed on a spectrum from dark red (lowest activity) to yellow/white (highest). As can be observed, an orgasm leads to almost the entire brain illuminating yellow, indicating that most brain systems become active at orgasm.
In a literature review recently published in the Journal of Evolutionary Zoology, a pair of developmental evolutionary specialists posit that as the female reproductive system evolved, so did the role of the orgasm. Once necessary for conception, female orgasms now appear to be a bonus for human intercourse. But similar to vestigial organs like tonsils or appendix, the orgasm remained.
This has long confused scientists, who in the past came up with two hypotheses. Some think that women do need orgasms to reproduce, but researchers have not yet figured out why. Others consider orgasms to be happy accidents associated with the clitoris, the organ responsible for sexual stimulation that is sometimes thought of as the female version of the male penis.
This surge of hormones, including prolactin and oxytocin, is similar to other surges observed in animals like rats, who need these natural chemicals to tell their body to ovulate. The surge can also help eggs implant in species like rodents. Some studies even suggest that humans have similar connections between egg implantation with post-orgasmic hormone shifts.
That hormone-orgasm connection in both humans and induced ovulators led Pavličev to believe that they were once connected long before humans became a species. She speculates that spontaneous ovulation likely evolved in the last common ancestor of primates and rodents. Eventually, however, they must have evolved into so-called spontaneous ovulators, but the hormonal reactions associated with orgasms remained.
The new work addresses what David Puts, a biological anthropologist at Pennsylvania State University, University Park, calls "one of the most contentious questions in the study of the evolution of human sexuality: whether women's orgasm has an evolutionary function." There are more than a dozen theories about the evolution of orgasms, most proposed decades or more ago. They include arguments that women have orgasms because their reproductive machinery has the same origins as those of men, who need to have orgasms to ejaculate sperm. Others think orgasms are an evolutionary novelty that persists because it helps foster loyal partners. Some have proposed that female orgasms induce physiological changes that increase the chances of conception, but there's no strong evidence that women who have more have increased fecundity.
Orgasm itself may have no evolutionary function, but it is derived from a key part of the reproductive cycle, Pavlićev and her colleague propose today in the Journal of Experimental Zoology Part B: Molecular and Developmental Evolution. Pavlićev didn't start out studying orgasms. To better understand the evolution of reproduction, she was compiling data on the ovarian cycle in different mammal species. During this cycle, cells destined to become eggs mature, escape from the ovary, and travel down the reproductive tract. She discovered that in some species, environmental factors control egg maturation and subsequent ovulation; in others, such as rabbits, sexual intercourse with a male or even just his presence causes the release of the egg. In either case, a series of changes involving the hormones oxytocin and prolactin are triggered that cause the egg to mature and migrate. In humans and other primates, the ovulatory cycle has become spontaneous, generally on a set schedule that requires neither an environmental trigger nor a male. Pavlićev then realized that women still undergo the same hormonal changes as species with induced ovulation, but during orgasm.
Jannini and others point out, however, that this theory needs more confirmation. So far, it deals only with the parallels between the hormonal surges in females during male-induced ovulation and orgasm, but has not looked to see whether there are also parallels in the neurological components of these activities, says Elisabeth Lloyd, a philosopher of science at Indiana University, Bloomington, who was not involved with this work. And because it's so difficult to assess whether other mammals feel the pleasure associated with orgasms, the work can only ever address the evolution of some of the components of female orgasm, Puts notes.
Others more strongly criticized the new explanation. Two behavioral neuroendocrinologists, Michael Baum from Boston University and Kim Wallen from Emory University in Atlanta, tell Science that Pavlićev and Wagner misinterpret some previously published results and do not have the details about the hormonal changes during ovulation and orgasm correct. "Their hypothesis remains a good hypothesis," Wallen says. "But I'm not very convinced by the data they marshal."
Lloyd says the work drives home how much more we need to learn about female sexuality in other organisms. Wagner and Pavlićev concede that more data are needed to firm up their theory, though for now they have no plans to follow up themselves. Cohn predicts others will pick up the baton. "Pavlićev and Wagner have taken a fascinating, creative, and thoughtful approach to a problem that has been investigated by many but resolved by few," he says. "I suspect that many investigators will be stimulated to further test the hypotheses raised in this paper." 2ff7e9595c
