Background: The 2D:4D digit ratio (DR), representing the relative length of the index finger to the ring finger, is an anthropometric marker that shows sexual dimorphism, with males typically having a lower ratio than females. This parameter is linked to prenatal androgen exposure (PAE), which influences sexual differentiation of the brain and behavior. This study aimed to investigate the correlation between PAE and sleep among young adults.

The recent reconceptualization of the phenomenon of sexting between consensual and nonconsensual represents a relevant turning point in identifying and addressing nonconsensual sexting behaviors as online sexual violence. These practices of nonconsensual sexting, therefore, represent forms of technology-facilitated sexual violence, incorporating the terms image-based sexual harassment (IBSH) and image-based sexual abuse (IBSA) to describe the distribution of self-produced sexualized images in the online sphere by adolescents, who use the online environment as their main socialization space. The objective of this investigation is dual.

Abuse of new drugs, such as Rush poppers, methamphetamine, Magu, Ketamine, and Ecstasy, is common among men who have sex with men (MSM) in China, leading to increased risks of sexually explicit media consumption, sexual violence, and sexual risk behaviors. This study aimed to explore the prevalence and relationships of these behaviors among MSM with new drug abuse. A cross-sectional study was conducted from January to June 2021, involving 453 MSM in Jinan, China.

Phytoestrogens are non-steroidal compounds that, can act as agonists and/or antagonists by binding to estrogen receptors; hence they can modify estrogen-dependent processes of neonatal sexual differentiation. Results of the analysis of the sexual behavior of experimental rats that received 6.8 mg of isoflavones/kg/day, showed significantly more mating activity, but fewer ejaculations (p<0.

Sperm competition is found across multicellular organisms using both external and internal fertilization. Sperm competition and post-copulatory cryptic female choice can promote incompatibility between species due to the antagonistic coevolution of the sexes within a species. This between-species incompatibility is accelerated and markedly asymmetrical when sexual mode differs, producing the "weak inbreeder, strong outcrosser" (WISO) pattern.
