Background: Phthalate exposure results in endocrine disruption by inhibiting steroidogenesis, inducing focal dysgenesis and disrupting germ cell development in the rat fetal testis. Whilst phthalate exposure does not reduce testosterone production by the human fetal testis, its effects on germ cells and induction of dysgenetic areas in the developing human testis are less well described.Objective and Hypotheses: To determine the effects of phthalate expo...

Background: In adult women, serum levels of AMH reflect both the number of small growing follicles and remaining primordial follicles. AMH levels range 15 fold between healthy girls. Interpretation of AMH is contentious due to minor intra-individual changes around time of pubertal onset despite continuous loss of primordial follicles.Objective and Hypotheses: To describe ovarian morphology (volume, follicles) in healthy girls and adolescents in relation ...
