Abstract
Gender-affirming hormone therapy (GAHT) can help transgender and/or gender diverse (TGD) individuals achieve emobidment goals that align with their transition needs. Clinical evidence from estradiol (E)-GAHT patients indicate widespread changes in tissues sensitive to E and testosterone (T), particularly in the reproductive system. Notably, E-GAHTs effects on hormones and reproduction vary greatly between patients. With the goal of informing clinical research and practice for TGD individuals taking E, this study examines intact male mice implanted with capsules containing one of three different E doses (low 1.25 mg; mid 2.5 mg; high 5 mg), or a blank control capsule. All E-GAHT doses suppress T and follicle stimulating hormone levels while elevating E levels. Only the high E-GAHT dose significantly supresses luteinizing hormone levels. All E-GAHT doses affect epididymis tubule size similarly while seminiferous tubule morphology and bladder weight changes are dose-dependent. E-GAHT does not alter the presence of mature sperm, though E-exposed sperm have altered motility. These data represent the first evidence that mouse models offer an effective tool to understand E-GAHTs impact on reproductive health and the dose-dependent effects of this model permit examinations of diverse patient outcomes.

Abstract
Tilorone analogue (R 10.874) has a close affinity to the lysosomal compartment of cells and forms a non degradable carbohydrate-lipid-drug complex accumulated within digesting organelles. Resembling biochemical and structural changes are seen in hereditary mucopolysaccharidoses accompanied with abnormal dendritogenesis. On the other hand, developmental toxicity (TERRY et al. 1992), antiproliferative effects (ALGARRA et al. 1993) and interactions with DNA (GELLER et al. 1985) are generated by tilorone. Therefore it should be interesting to know whether the amphiphilic cationic compound is able to produce an abnormal dendritogenesis as in storage diseases or an impaired arborisation of dendrites and what could be the reason for the misdevelopment. We demonstrate that there was a fetal retardation in the development of dendritic network, even under influence of low dosis of the analogue R 10.874. The dendritic dismaturation was concomitant with an increased amount of fatty acids and a slightly disarranged metabolic pathway of gangliosides. The dendritic arborisation closed the gap of retarded development between intrauterine treated and untreated rats after 7 days of postnatal drug elimination. We suppose that a fetotoxic effect and not the lysosomopathy is responsible for the reduced dendritic network.
