  • Sex and Pregnancy: TSOS Podcast, Ep. 11!

    We love talking about sex, but what about sex during pregnancy and after childbirth? Goes Deeper Earlier this year, two researchers at the University of Nebraska at Omaha published a review paper summarizing what we know from research about sexual behaviors during pregnancy and the year after childbirth. They combed through 56 empirical studies published in the academic literature since 1996, and found that, in general, there was a gradual decline in vaginal intercourse over the course of pregnancy and the first couple of months post-childbirth. This week we were able to interview the lead author on this paper, Dr.

  • The Top 5 Reasons Marriages And Cohabitations End

    Most of the studies focusing on divorce and the ending of relationships and cohabitations are based on qualitative research, not quantitative but a new study out of the UK overcomes the disadvantages of past research and provides a clearer insight into why live-in partnerships come to an end. The data come from NATSAL-3, a nationally representative survey of over 15,000 UK residents ages 16-74 interviewed between 2010 and 2012. Overall, 11% of the men and 14% of the women in the sample reported they experienced the end of a live-in partnership (marital or cohabiting) in the 5 years prior to interview (2% of men’s and

  • Sexual Dysfunction: TSOS Podcast, Ep. 10!

    How common are sexual problems and when should they be a cause for concern? Goes Deeper On this week’s episode of The Science of Sex, Joe and I had the pleasure of speaking with Dr. Kirstin Mitchell about her research on sexual function and disfunction. Dr. Mitchell is a Senior Research Fellow at the MRC/CSO Social and Public Health Sciences Unit, University of Glasgow, where she leads a theme of research on Families and Intimate & Sexual Relationships. We spoke with her about a few studies that she has published in regards to sexual dysfunction. Over the last 3 years, several

  • Feeling Ill After Ejaculating? You Might Have ‘Post-Orgasmic Illness Syndrome’

    Many of us are (unfortunately) aware of post-ejaculation guilt, but there is a small percentage of the population that experiences real physical illness after orgasm. These people suffer from “Post-Orgasmic Illness Syndrome (POIS).” If you haven’t heard of it, don’t worry, you’re not alone. POIS is a very rare disorder among men (and possibly women) that causes flu-like and allergic symptoms following ejaculation. POIS manifests as a constellation of flulike and allergic symptoms, including fatigue, weakness of musculature, feverishness or perspiration, mood disturbances and irritability, memory and concentration problems, incoherent speech, nose congestion or watery nose, or itchy eyes. Different

  • Marijuana Users Have More Sex

    As marijuana use continues to grow in the United States, we are starting to learn more about its effects on our behavior. A new study using a nationally representative sample of over 50,000 US residents ages 15 to 44 found that, on average, marijuana users have more sex than nonusers. For example, women who reported no marijuana use during the past year had sexual intercourse 6.0 times on average during the past 4 weeks compared with 7.1 times for women who reported daily marijuana use. For men, these numbers were 5.6 for nonusers and 6.9 times for daily users. Increased sexual frequency was also

  • Marriage and Porn: TSOS Podcast Ep. 9!

    Can porn negatively impact a marriage? Goes Deeper This week on The Science of Sex, Joe and I went deeper into a rather controversial topic involving the impact that watching pornography can have on marital quality and longevity. We interviewed Dr. Samuel L. Perry, an assistant professor of sociology and religious studies at the University of Oklahoma, about two of his recent studies, both of which included nationally representative samples of married US adults that were followed over several years. One study, published in the Archives of Sexual Behavior, found married persons who watched porn more often in 2006 reported significantly lower levels of

  • A Woman’s Brain During Orgasm: TSOS Podcast Ep. 8!

    What is really going on in the female brain before, during, and after an orgasm? This week on The Science of Sex, Joe and I talk to Dr. Nan Wise, a licensed psychotherapist, cognitive neuroscientist, certified sex therapist, board certified clinical hypnotherapist, and certified relationship specialist with three decades of experience. Her research at Rutgers University has addressed gaps in the scientific literature regarding the neural basis of human sexuality, and has as a result, garnered international attention. This fall, Dr. Wise published a study in the Journal of Sexual Medicine that disputed past research of brain scans of women during orgasm.

  • There’s Growing Evidence For A Link Between Gender Dysphoria And Autism Spectrum Disorders

    We might have reason to believe that there is a connection between Autism Spectrum Disorder (ASD) and gender dysphoria, according to science. This possible link was first brought to light in the 1980’s when a study noted that 10% of the participants, all of whom had been diagnosed with ASD, had trouble answering a question regarding their personal gender identity. Since 2010, at least nine large scale studies have been conducted regarding this subject matter and found that traits of autism were prevalent in 5%-54% of those with gender dysphoria. Several different hypotheses have been proposed to explain the heightened link

  • All About Asexuality: TSOS Podcast Ep. 7!

    We often talk about issues regarding the gay, lesbian, and bisexual communities, but what about those who identify as asexual? On the latest episode of The Science of Sex, Joe and I dove into an interesting yet rarely discussed topic of conversation all about asexuality and its relationship to mental health. Our guest on the show was Lara Greaves, a student in her last month of a PhD in the School of Psychology at the University of Auckland, New Zealand. Her research is broadly in the area of social psychology and includes everything from indigenous voter turnout to the psychological recovery

In a new #fMRI study, researchers investigated neural correlates of responses to erotic stimuli in 26 heterosexual, 26 #bisexual, and 24 #homosexual women, ages 25–50. Results confirm other research on #sexualorientation: #lesbians (like #gay and straight men) show greater brain activation to images of women (vs. men), but hetero women’s brains are like those of #bisexuals, responding equally to male and female stimuli. The takeaway? Homosexual women have greater #gender bias in their responses to male and female erotic stimuli. Interestingly, this study is also the first of its kind to include bisexual women!
