In rodents, a pup's experiences in utero and during postnatal development shape its sexual behavior as an adult and how it is perceived by potential mates. We show that the male rat's sexuality is primarily influenced by the postnatal sex ratio of its litter, but not by the litter's prenatal intrauterine sex ratio or the behavior of its mother. Pups from litters with differing prenatal sex ratios were divided into litters with differing postnatal sex ratios. We found that males raised in a female-biased litter exhibited less mounting than males raised in either a male-biased litter or one with an equal sex ratio, and were less attractive to sexually receptive females, eliciting fewer soliciting behaviors, such as hop-darts, and fewer lordosis behaviors. However, the number of intromissions and ejaculations did not differ across groups, which suggests that males from female-biased litters mate as efficiently as males raised in other sex ratios, but do not require as many mounts to do so. The reported differences in sexual behavior did not vary with the quality of maternal behavior or with sexual experience in adulthood.

The antipsychotic medication haloperidol has been used for many years in avian medicine as a pharmacologic therapy for refractory feather destructive behavior in pet parrots. However, despite its common use, there are no published studies evaluating its efficacy and adverse effects in psittacine birds. The goal of this study was to report the signalment, clinical presentation, dosing regimen, response to therapy, and adverse effects of companion psittacine birds prescribed oral haloperidol therapy at a single veterinary referral hospital.

The impact of gynaecological cancer and its treatments on sexual intimacy can be profound on female sexuality. However, very few registered clinical trials have addressed sexual intimacy among this cohort. This preliminary randomised control trial (RCT) and content analysis assessed the effectiveness of a brief online mindful compassion group intervention adjunct with cannabis suppositories.

Health risk behaviors continue to disproportionately affect Hispanic youth. Despite the existence of successful family and school-based interventions, there is a need for developing and testing individually-based preventive interventions that are easily accessed and widely disseminated. Therefore, this study aimed to develop a prototype (proof of concept) for an individual-level mobile application (app), informed by Hispanic parents and adolescents, to prevent/reduce drug use and sexual risk behaviors among Hispanic youth.

This study aims to address the gap in understanding condom use (CU) behavior in Flanders (the Dutch-speaking community in Belgium) by applying a mixed methods approach, integrating both quantitative and qualitative data. Utilizing a large-scale survey of over 14,000 participants and 11 in-depth interviews, the study explores key factors influencing CU, including (amongst others) relationship status, attitudes toward condoms, and STI testing. Quantitative findings highlight significant predictors such as the type of partner (casual vs.
