Speciation by divergent natural selection is well supported. However, the role of sexual selection in speciation is less well understood due to disagreement about whether sexual selection is a mechanism of evolution separate from natural selection, as well as confusion about various models and tests of sexual selection. Here, we outline how sexual selection and natural selection are different mechanisms of evolutionary change, and suggest that this distinction is critical when analyzing the role of sexual selection in speciation. Furthermore, we clarify models of sexual selection with respect to their interaction with ecology and natural selection. In doing so, we outline a research agenda for testing hypotheses about the relative significance of divergent sexual and natural selection in the evolution of reproductive isolation.

New insights into the goals of transgender male versus non-binary individuals considering metoidioplasty and phalloplasty gender-affirming surgery.
J Sex Med
January 2025
Department of Surgery, Section of Urology, Dartmouth Hitchcock Medical Center, Lebanon, NH 03756, United States.
Background: Understanding patient goals for metoidioplasty and phalloplasty gender-affirming surgery (MaPGAS) is paramount to achieving satisfactory, preference-sensitive outcomes, yet there is a lack of understanding of MaPGAS priorities and how these may vary between transgender men and non-binary individuals assigned female at birth (AFAB).
Aim: To understand the surgical goals of transgender men and non-binary individuals AFAB considering MaPGAS.
Methods: An online survey was created following literature review and qualitative interviews and distributed via social media and a community health center to participants AFAB aged ≥18 years who had considered but not yet undergone MaPGAS.
Identifying the Strongest Correlates of Condom Use Among US Adolescents: A Systematic Review and Meta-Analysis.
JAMA Pediatr
January 2025
University of Pittsburgh, Pittsburgh, Pennsylvania.
Importance: Condoms are effective at preventing sexually transmitted infections and pregnancy; however, only 52% of sexually active US adolescents used a condom at last intercourse.
Objective: To examine (1) the association between 36 psychosocial variables and adolescent condom use to determine the strongest correlates of condom use behavior across the literature, (2) heterogeneity of these effects, and (3) the moderating roles of age, gender/sex, race/ethnicity, sexual orientation, and year of study.
Data Sources: A systematic search was conducted of studies published between January 2000 and February 2024 using Medline, CINAHL, PsycINFO, and Communication Source databases, plus relevant review articles and unpublished data.
Host Plant Odour and Sex Pheromone are Integral to Mate Finding in Codling Moth.
J Chem Ecol
January 2025
Department Plant Protection Biology, SLU Alnarp, Lomma, Sweden.
The great diversity of specialist plant-feeding insects suggests that host plant shifts may initiate speciation, even without geographic barriers. Pheromones and kairomones mediate sexual communication and host choice, and the response to these behaviour-modifying chemicals is under sexual and natural selection, respectively. The concept that the interaction of mate signals and habitat cues facilitates reproductive isolation and ecological speciation is well established, while the traits and the underlying sensory mechanisms remain unknown.

Sexual signals in animals encompass a variety of forms including visual, acoustic, and chemical signals that are fundamental for intra- and interspecific communication, including sexual selection processes. Among these, odor signals play a critical role. Chemical compounds involved in sexual signaling vary in nature, with lipids and proteins being particularly important.

Purpose Of Review: Antimicrobial resistance in sexually transmitted infections (STIs) has become an urgent global public health threat, raising the specter of untreatable infections. This review summarizes the determinants of resistance among the five most common curable STIs Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, Treponema pallidum, and Trichomonas vaginalis, as well as strategies to mitigate the spread of resistance.
Recent Findings: Genetic mutations are key drivers of resistance for N.
