Researchers link flibanserin-induced decreases in female brain metabolism to increased pair bonding and grooming behavior in common marmosets. The study provides insight into how the drug may work in women's brains, but highlights room for improvement in treatment and safety.
A new study from Karolinska Institutet found a significant link between maternal polycystic ovarian syndrome (PCOS) and autism spectrum disorders (ASD) in children. The study, which analyzed data from over 24,000 ASD cases and 200,000 controls, suggests that exposure to sex hormones early in life may play a role in the development of ASD.
A study of 47 men with erectile dysfunction found that 79% were satisfied with the outcome of penile prosthesis surgery. The benefits included improved sexual function, enhanced male identity, and relationship improvements. Most men reported positive emotions, self-esteem, confidence, and increased desire after receiving the implant.
Hypersexuality correlated with sexual boredom and erectile dysfunction in a study of Croatian and German men. Therapies for hypersexual men may include sex therapy principles to enhance erectile functioning and address sexual boredom.

The study's authors emphasize the need for easy access to effective care and open discussion of sexual health concerns among veterans.
Studies reveal high rates of male military sexual trauma due to stigma and shame, affecting mental health outcomes. Female veterans who experienced assault are also at risk of PTSD and delayed seeking help.
A study of 713 male patients with sleep apnea found a clear link between low quality of life due to sleep problems and erectile dysfunction. Psychological interventions may help improve the sexual health of these men.
Researchers found that the antidepressant sertraline increased the volume of one brain region in depressed subjects, while decreasing two brain areas in non-depressed subjects. The study used middle-aged female monkeys to replicate human depression and tested the effects of sertraline on brain volumes.
Individuals with sex development disorders face challenges forming positive relationships due to physical differences. Researchers suggest raising public awareness of the diverse nature of bodies and providing practical support mechanisms, such as private locker rooms and support groups.

A study of 1159 males who illicitly used amphetamines found that half reported no impact on sexual functions, while the other half experienced reduced erectile rigidity, enhanced orgasmic intensity, and delayed ejaculation. Amphetamine users were also twice as likely to experience erectile dysfunction compared to matched controls.
Researchers examined nationwide trends in erectile dysfunction and surgical management from 2001 to 2010. The study found that while erectile dysfunction prevalence increased, penile prosthesis use decreased, but was more common in sicker patients.
A new study shows that physical resistance training significantly improves sexual function, desire, arousal, and lubrication in women with polycystic ovary syndrome. Additionally, it decreases anxiety and depression, suggesting a useful intervention for these individuals.
