Objectives: This study sought to examine the effects of government policies and neighborhood characteristics on adolescent female sexual behavior to better inform future public policy decisions.
Methods: Using a bivariate probit model and National Survey of Family Growth data on women aged 15 through 19 years, we estimated the probabilities of their being sexually active and, if sexually active, of their using contraceptives.
Results: Variables measuring the cost of obtaining an abortion are not good predictors of sexual activity or contraceptive use. However, the relationship between family planning availability and contraceptive use is statistically significant at conventional levels.
Conclusions: Policymakers seem to have little leverage with regard to influencing the decision to become sexually active, although increased access to family planning services may encourage responsible contraceptive behavior. Neighborhood context is an important determinant of adolescent female sexual behavior.

Astrocytes exhibit diverse cellular and molecular properties across the central nervous system (CNS). Recent studies identified region-specific transcription factors (TF) that oversee these diverse properties; how sex differences intersect with region-specific transcriptional programs to regulate astrocyte function is unknown. Here, we show that the TF Nkx6.

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.

Background: The use of medical abortion using either a combination of mifepristone and misoprostol, or misoprostol alone has contributed to increased safety and decreased mortality and morbidity. The availability of quality medical abortion medicines is an essential component in the provision of quality abortion care. Understanding the factors that influence the availability of medical abortion medicines is important to help in-country policymakers, program planners, and providers improve availability and use of medical abortion.

Successful transmission of Plasmodium falciparum from one person to another relies on the complete intraerythrocytic development of non-pathogenic sexual gametocytes infectious for anopheline mosquitoes. Understanding the genetic factors that regulate gametocyte development is vital for identifying transmission-blocking targets in the malaria parasite life cycle. Toward this end, we conducted a forward genetic study to characterize the development of gametocytes from sexual commitment to mature stage V.
