Treatment of congenital adrenal hyperplasia and Klinefelter Syndrome with central precocious puberty: a case report.

Transl Pediatr 2022 Feb;11(2):298-305

Department of Endocrinology, Shanghai Children's Hospital, Shanghai Jiao Tong University, Shanghai, China.

The simultaneous occurrence of Klinefelter syndrome (KS) and congenital adrenal hyperplasia (CAH) is extremely rare, as the former causes androgen deficiency, while the latter results in androgen excess. In addition, central precocious puberty (CPP) will occur, which is caused by the activation of the hypothalamic-pituitary-gonadal (HPG) axis by androgens. We present the 7th reported case of simultaneous KS and CAH in a boy with CPP due to protopathy of CAH. Read More

Current concepts surrounding neonatal hormone therapy for boys with congenital hypogonadotropic hypogonadism.

Expert Rev Endocrinol Metab 2022 01 7;17(1):47-61. Epub 2022 Jan 7.

Department of Endocrinology, Diabetes & Metabolism Royal Victoria Infirmary, Newcastle-Upon-Tyne Hospitals, Newcastle-upon-Tyne, UK.

Introduction: Congenital hypogonadotropic hypogonadism (CHH) is a genetic disorder of reproduction and development, characterized by deficient gonadotropin-releasing hormone (GnRH) secretion or action, affecting 1-in-4,000-15,000 males. Micropenis and undescended testes are cardinal features of antenatal GnRH deficiency and could indicate absent minipuberty in the first postnatal months. In this review, we outline the pathophysiology and clinical consequences of absent minipuberty and its implications for optimal approaches to the endocrine management of affected boys. Read More

Should Skeletal Maturation Be Manipulated for Extra Height Gain?

Authors:
Jan M Wit

Front Endocrinol (Lausanne) 2021 16;12:812196. Epub 2021 Dec 16.

Division of Pediatric Endocrinology, Department of Pediatrics, Willem-Alexander Children's Hospital, Leiden University Medical Center, Leiden, Netherlands.

Skeletal maturation can be delayed by reducing the exposure to estrogens, either by halting pubertal development through administering a GnRH analogue (GnRHa), or by blocking the conversion of androgens to estrogens through an aromatase inhibitor (AI). These agents have been investigated in children with growth disorders (off-label), either alone or in combination with recombinant human growth hormone (rhGH). GnRHa is effective in attaining a normal adult height (AH) in the treatment of children with central precocious puberty, but its effect in short children with normal timing of puberty is equivocal.

Evidence for Perinatal Steroid Influence on Human Sexual Orientation and Gendered Behavior.

Cold Spring Harb Perspect Biol 2021 Dec 6. Epub 2021 Dec 6.

Neuroscience Program, Michigan State University, East Lansing, Michigan 48824, USA.

In laboratory animals, exposure to gonadal steroid hormones before and immediately after birth can exert permanent effects on many behaviors, particularly reproductive behaviors. The extent to which such effects occur in humans remains an open question, but several lines of evidence indicate that perinatal levels of both androgens and estrogens may affect adult human psychology and behavior, including sexual orientation and gender nonconformity. Some putative indicators of prenatal androgen exposure, including the ratio of the length of the index finger to that of the ring finger (2D:4D), have repeatedly indicated that lesbians, on average, were exposed to more prenatal androgens than straight women, suggesting that sufficient fetal androgen exposure predisposes a fetus to gynephilia (attraction to women) at maturity.

Next-generation sequencing-based mutational analysis of idiopathic short stature and isolated growth hormone deficiency in Korean pediatric patients.

Mol Cell Endocrinol 2022 03 12;544:111489. Epub 2021 Oct 12.

Department of Pediatrics, Severance Children's Hospital, College of Medicine Yonsei University, Seoul, South Korea. Electronic address:

We investigated the distribution of short stature-associated mutations in Korean pediatric patients with idiopathic short stature (ISS) and isolated growth hormone deficiency (IGHD) via targeted next-generation sequencing (TNGS). We employed a 96-gene TNGS panel for short stature in a total of 144 patients (5-19 years-old) previously diagnosed with ISS or IGHD and identified heterozygous pathogenic or likely pathogenic genetic variants in 14 (10%) patients. Of the mutated genes, PROKR2 (n = 3) is associated with gonadotropin-releasing hormone deficiency or hypopituitarism, while FGFR1 (n = 1) and NPR2 (n = 3) encode growth plate paracrine factors.

Non-GH Agents and Novel Therapeutics in the Management of Short Stature.

Indian J Pediatr 2021 Dec 1;88(12):1209-1213. Epub 2021 Jul 1.

Division of Pediatric Endocrinology, Department of Pediatrics, Riley Hospital for Children at IU Health, Indiana University School of Medicine, Indianapolis, IN, USA.

Short stature is one of the most common reasons for referral to pediatric endocrinologists. The vast majority of short children do not have growth hormone (GH) deficiency or another pathologic process that is interfering with normal growth. While GH has been approved in the US for several etiologies of non-GH deficient short stature, its high cost and need for daily injections represent barriers for many families. Read More

Deficiency of arcuate nucleus kisspeptin results in postpubertal central hypogonadism.

Am J Physiol Endocrinol Metab 2021 08 28;321(2):E264-E280. Epub 2021 Jun 28.

Department of Pediatrics, Child Health Institute of New Jersey, Rutgers-Robert Wood Johnson Medical School, Rutgers, the State University of New Jersey, New Brunswick, New Jersey.

Kisspeptin (encoded by ), a neuropeptide critically involved in neuroendocrine regulation of reproduction, is primarily synthesized in two hypothalamic nuclei: the anteroventral periventricular nucleus (AVPV) and arcuate nucleus (ARC). AVPV kisspeptin is thought to regulate the estrogen-induced positive feedback control of gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH), and the preovulatory LH surge in females. In contrast, ARC kisspeptin neurons, which largely coexpress neurokinin B and dynorphin A (collectively named KNDy neurons), are thought to mediate estrogen-induced negative feedback control of GnRH/LH and be the major regulators of pulsatile GnRH/LH release.

A closer look at the role of insulin for the regulation of male reproductive function.

Gen Comp Endocrinol 2021 01 2;300:113643. Epub 2020 Oct 2.

Neurosciences Research Center, Tabriz University of Medical Sciences, Tabriz, Iran. Electronic address:

While insulin demonstrates to have a considerable influence on the reproductive system, there are various unanswered questions regarding its precise sites, mechanisms of action, and roles for the developing and functioning of the adult male reproductive system. Apart from its effects on glucose level, insulin has an important role in the reproductive system directly by binding on insulin and IGF receptors in the brain and testis. To date, however, the effect of insulin or its alterations on blood-testis-barrier, as an important regulator of normal spermatogenesis and fertility, has not yet been studied. Read More

Increased Burden of Rare Sequence Variants in GnRH-Associated Genes in Women With Hypothalamic Amenorrhea.

J Clin Endocrinol Metab 2021 03;106(3):e1441-e1452

National Institute of Environmental Health Sciences, National Institutes of Health (NIH), Research Triangle Park, North Carolina.

Context: Functional hypothalamic amenorrhea (HA) is a common, acquired form of hypogonadotropic hypogonadism that occurs in the setting of energy deficits and/or stress. Variability in individual susceptibility to these stressors, HA heritability, and previous identification of several rare sequence variants (RSVs) in genes associated with the rare disorder, isolated hypogonadotropic hypogonadism (IHH), in individuals with HA suggest a possible genetic contribution to HA susceptibility.

Objective: We sought to determine whether the burden of RSVs in IHH-related genes is greater in women with HA than controls. Read More

TCF12 haploinsufficiency causes autosomal dominant Kallmann syndrome and reveals network-level interactions between causal loci.

Hum Mol Genet 2020 08;29(14):2435-2450

Center for Human Disease Modeling, Duke University, Durham, NC 27701, USA.

Dysfunction of the gonadotropin-releasing hormone (GnRH) axis causes a range of reproductive phenotypes resulting from defects in the specification, migration and/or function of GnRH neurons. To identify additional molecular components of this system, we initiated a systematic genetic interrogation of families with isolated GnRH deficiency (IGD). Here, we report 13 families (12 autosomal dominant and one autosomal recessive) with an anosmic form of IGD (Kallmann syndrome) with loss-of-function mutations in TCF12, a locus also known to cause syndromic and non-syndromic craniosynostosis.

Pubertal timing predicts adult psychosexuality: Evidence from typically developing adults and adults with isolated GnRH deficiency.

Psychoneuroendocrinology 2020 09 6;119:104733. Epub 2020 Jun 6.

Department of Anthropology, Pennsylvania State University, Carpenter Building, University Park, PA, 16802, USA. Electronic address:

Evidence suggests that psychosexuality in humans is modulated by both organizational effects of prenatal and peripubertal sex steroid hormones, and by activational effects of circulating hormones in adulthood. Experimental work in male rodents indicates that sensitivity to androgen-driven organization of sexual motivation decreases across the pubertal window, such that earlier puberty leads to greater sex-typicality. We test this hypothesis in typically developing men (n = 231) and women (n = 648), and in men (n = 72) and women (n = 32) with isolated GnRH deficiency (IGD), in whom the precise timing of peripubertal hormone exposure can be ascertained via the age at which hormone replacement therapy (HRT) was initiated.

Hypogonadotropic hypogonadism due to variants in : expanding the phenotypic and genotypic spectrum of Martsolf syndrome.

Cold Spring Harb Mol Case Stud 2020 06 12;6(3). Epub 2020 Jun 12.

Harvard Reproductive Endocrine Sciences Center, Reproductive Endocrine Unit of the Department of Medicine, Massachusetts General Hospital, Boston, Massachusetts 02114, USA.

Biallelic pathogenic variants in cause Warburg Micro syndrome (WARBM) and Martsolf syndrome (MS), two rare, phenotypically overlapping disorders characterized by congenital cataracts, intellectual disability, and hypogonadism. Although the initial report documented hypergonadotropic hypogonadism (implying a gonadal defect), an adolescent girl with WARBM/MS was subsequently reported to have hypogonadotropic hypogonadism (implying a central defect in either the hypothalamus or anterior pituitary). However, in adult MS, hypogonadotropism has not been convincingly demonstrated. Read More
