Anti-Müllerian hormone (AMH) is secreted by Sertoli cells of the testes from early fetal life until puberty, when it is downregulated by androgens. In conditions like complete androgen insensitivity syndrome (CAIS), AMH downregulation does not occur

Meiosis begins at puberty and relies on several factors, including androgens and retinoic acid in the mouse testis. CYP26B1 degrades retinoic acid in the testis during prenatal development preventing meiosis initiation. Given the concurrence of meiot

Testicular anti-Müllerian hormone (AMH) production is inhibited by androgens around pubertal onset, as observed under normal physiological conditions and in patients with precocious puberty. In agreement, AMH downregulation is absent in patients wit

In pediatric patients, basal testosterone and gonadotropin levels may be uninformative in the assessment of testicular function. Measurement of serum anti-Müllerian hormone (AMH) has become increasingly widespread since it provides information about

Background and objective: Controversial effects of bisphenol A (BPA) have been reported on testicular function. These differences might reflect dissimilar exposure conditions. Dose responses to toxicants may be non-linear, e.g. U-shaped, with effects

Summary: The hormonal regulation of γ-glutamyl transpeptidase (γ-GTP), an enzyme marker of Sertoli cells, was studied in immature rats that received 50 μg/day of testosterone propionate (TP) during 6 days to suppress pituitary LH and FSH. Suppress

We analyzed the potential role of oxidative stress induced by mono (2-ethylhexyl) phthalate (MEHP) in adherent cell junction protein expression of prepubertal rat Sertoli cells (SC) in vitro. Five-day SC cultures were treated with MEHP (200 µM) for

The aim of the study was to determine whether arachidonic acid (AA) is involved in the regulation of Sertoli cell lactate production and if this fatty acid participates in follicle-stimulating hormone (FSH) regulation of Sertoli cell function. In a f

In early fetal development, the testis secretes – independent of pituitary gonadotropins – androgens and anti-Müllerian hormone (AMH) that are essential for male sex differentiation. In the second half of fetal life, the hypothalamic–pituitary

In the present study, a possible role of ceramide in the regulation of Sertoli cell function was investigated. Intracellular ceramide levels were increased by adding N-acetylsphingosine (C2) or by inhibiting ceramidase with (1 S,2R)-D-erythro-2-(N-my
