Background: Bisphenol F (BPF), a substitute for bisphenol A (BPA), is widely used in consumer products, increasing the potential for environmental exposure. Our study investigated the reproductive effects of BPF on adult male zebrafish and explored its toxicological mechanisms, as well as its intergenerational effects.
Methods: Adult male zebrafish were exposed to BPF concentrations of 0, 50, 500, 2500, and 5000 nM for 21 days.

There is limited research concerning the transgender population's health issues, such as gender dysphoria, and disparities within the healthcare system, especially in the Latino or Hispanic population. This study aimed to report the case of a Puerto Rican transgender man who achieved pregnancy without reproductive assistance after cessation of testosterone therapy for 3 months and who in the postpartum period experienced significant gender dysphoria. A narrative literature review was carried out to identify the role of gender dysphoria in pregnancy, lactation, health-related spaces, and mental health.

Biol Sex Differ
January 2025
Department of Nuclear Medicine, University Hospital Zurich, Zurich, CH-8091, Switzerland.
Background: Presentations and outcomes of acute myocardial infarction (MI) differ between women and men, with the worst outcomes being reported in younger women. Mental stress induced ischemia and sympathetic activation have been suggested to play a prominent role in the pathogenesis of MI in younger women, however, the impact of sex hormones on these parameters remains unknown.
Methods: The effect of sex hormones and age on myocardial infarct size and myocardial sympathetic activity (MSA) was assessed in male and female, as well as young (4-6 months) and aged (20-22 months) FVB/N mice (n = 106, 60 gonadectomized and 46 sham-operated animals) who underwent in vivo [C]meta-hydroxyephedrine ([C]mHED) positron emission tomography (PET) and cardiac magnetic resonance (CMR) imaging 24 h after a 30 min myocardial ischemic injury.
