A continuously increasing amount of research shows that oxytocin is involved in numerous central functions. Among the functions in which oxytocin is thought to be involved are those that play a role in social and sexual behaviors, and the involvement of central oxytocin in erectile function and sexual behavior was indeed one of the first to be discovered in laboratory animals in the 1980s. The first part of this review summarizes the results of studies done in laboratory animals that support a facilitatory role of oxytocin in male and female sexual behavior and reveal mechanisms through which this ancient neuropeptide participates in concert with other neurotransmitters and neuropeptides in this complex function, which is fundamental for the species reproduction. The second part summarizes the results of studies done mainly with intranasal oxytocin in men and women with the aim to translate the results found in laboratory animals to humans. Unexpectedly, the results of these studies do not appear to confirm the facilitatory role of oxytocin found in male and female sexual behavior in animals, both in men and women. Possible explanations for the failure of oxytocin to improve sexual behavior in men and women and strategies to attempt to overcome this impasse are considered.

Social determinants of contraception use among rural adolescents: Implications for addressing disparities.
J Rural Health
January 2025
Independent Researcher, Seattle, Washington, USA.
Purpose: Few studies have examined disparities in-and social determinants of-contraception use among rural adolescents despite evidence of higher teen birth rates and greater STI risk in rural communities. Guided by a social determinants of health (SDoH) framework, this cross-sectional study aimed to address these gaps.
Methods: Data come from the 2018 Healthy Youth Survey, including N = 3757 sexually active, rural-based adolescents.
Male and female behavioral variability and morphine response in C57BL/6J, DBA/2J, and their BXD progeny following chronic stress exposure.

Drug addiction is a multifactorial syndrome in which genetic predispositions and exposure to environmental stressors constitute major risk factors for the early onset, escalation, and relapse of addictive behaviors. While it is well known that stress plays a key role in drug addiction, the genetic factors that make certain individuals particularly sensitive to stress and, thereby, more vulnerable to becoming addicted are unknown. In an effort to test a complex set of gene x environment interactions-specifically gene x chronic stress-here we leveraged a systems genetics resource: BXD recombinant inbred mice (BXD5, BXD8, BXD14, BXD22, BXD29, and BXD32) and their parental mouse lines, C57BL/6J and DBA/2J.

PLoS One
December 2024
Department of Midwifery, College of Health Sciences, Debre Tabor University, Debre Tabor, Ethiopia.
Background: Street women are women, who make their living on the streets by begging, sleeping in the streets, or on the sides of roads. They are the most marginalized and neglected segment of society, with little access to health care, including modern contraception, and a lack of knowledge about health services, particularly in Ethiopia. Therefore, this study aimed to examine modern contraceptive utilization and associated factors among street women.

Psychopharmacology (Berl)
December 2024
Evolutionary Genetics Department, Facultad de Ciencias, Universidad de la República, Montevideo, Uruguay.
Rationale: The sexual behavior of the female rat is highly motivated, and the mesocorticolimbic dopaminergic system -involved in psychostimulants effects- has been implicated in its regulation. Female rats begin to express sexual behavior during adolescence, a period during which this system is not yet mature.
Objective: To examine the impact of cocaine on sexual motivation and behavior of adolescent and adult female rats, and to determine the dopamine receptors binding in mesocorticolimbic areas of these females.
Association between women empowerment and contraceptive utilization in Ethiopia.
Womens Health (Lond)
December 2024
Department of Pharmacy, College of Health Sciences, Wollaga University, Nekemte, Ethiopia.
Background: Women's empowerment is essential for achieving sustainable development goals. It involves enabling women to take control of their lives by giving them the agency, resources, and opportunities they need to make their own choices and reach their full potential. If more women are empowered to use modern contraceptives, greater reductions in maternal mortality will follow.
