Kallmann syndrome (KS) is a rare pediatric disease with major manifestations of olfactory dysfunction and hypogonadotropic hypogonadism. Five children (4 boys and 1 girl) with KS reported in this article were aged between 6 months and 19 years at the time when they attended the hospital. All the children had the clinical manifestation of hypogonadotropic hypogonadism; in addition, three children had olfactory dysfunction (two were found to have olfactory bulb dysplasia on magnetic resonance imaging), one had cleft lip and palate, and one had micropenis and cryptorchidism with right renal agenesis during infancy...

Oral-facial-digital syndrome type 1 (OFD1) is a ciliopathy characterized by oral, facial, and digital malformations that are often accompanied by polycystic lesion of the kidney and central nervous involvement. OFD1 shows an X-linked recessive inheritance caused by mutation in the OFD1 gene (Xp22.2). The disease is generally considered embryonic lethal for hemizygous males. However, males with OFD1 mutations were recently reported. Here, we report four additional Japanese male patients with OFD1 variants and describe the variable clinical manifestation and disease severity among the four patients...

Kleefstra syndrome is a genetic condition characterized by intellectual disability, childhood hypotonia, and facial dysmorphisms. Genital anomalies such as micropenis, cryptorchidism, and hypospadias have been reported in 30-40% of males diagnosed with the disease. However, endocrinological investigations have been limited. We describe a case of an adolescent male with Kleefstra syndrome due to a pathogenic variant in the EHMT1 gene whose workup for isolated micropenis is suggestive of a partial hypogonadotropic hypogonadism...

Although it is well known that penile growth is dependent on androgens, few clinical studies have reported successful treatment of micropenis with testosterone, likely due to concerns regarding the efficacy and safety of prolonged testosterone use. Thus, we assessed the synergenic effects of growth hormone (GH) treatments with and without testosterone on phallic growth in a rat model of micropenis. Fifty Sprague-Dawley rats were assigned to control (C), microphallus (MP), testosterone (T), GH (G) and GH plus testosterone (GT) treatment groups, and microphallus was induced by secondary hypogonadism...

The Bardet-Biedl syndrome is an autosomal recessive hereditary disorder with vast locus heterogeneity that belongs to the so-called ciliopathies, whose proteins are localized in the primary cilia and present functional deficiency. The multisystemic features of the disease include ocular, renal, cognitive, skeletal, as well as gonadal involvement and obesity, among others, with high inter- and intrafamilial variability. We describe the clinical case of an adolescent male patient with Bardet-Biedl syndrome, including the approach, the results from a 22-gene sequencing panel, and the analysis of updated scientific literature...

A 42-year-old African man presented with hypogonadic phenotypical features, including gynoid body distribution, gynaecomastia, absent facial and truncal hair and micropenis. He denied ever experiencing development of male secondary sex characteristics. Endocrine testing revealed hypergonadotropic hypogonadism and undetectable AMH. Human chorionic gonadotropin (hCG) stimulation test failed to increase testosterone levels. Peripheral blood karyotype was 46, XY. Clinical examination and abdominal/pelvic/scrotal ultrasound and MRI failed to identify any testicular structures/remnants...

BACKGROUND: Evidence-based guidelines on evaluation of boys with proximal hypospadias for the possibility of a disorder of sex development (DSD) have yet to be developed. We aimed to investigate the incidence and diagnoses of DSD in patients with proximal hypospadias. METHODS: We retrospectively reviewed the records of consecutive boys who underwent proximal hypospadias repairs from 2006 to Sept 2017. Data collected included scrotal anomaly, testes position/palpability, micropenis, DSD investigations, and surgical techniques...

BACKGROUND: The term holoprosencephaly was proposed by DeMyer and Zeman. It is a developmental defect of the embryonic forebrain with heterogeneous etiology including genetic and environmental factors. It is commonly associated with midfacial defects and has a spectrum of presentations. There are four types: alobar, semilobar, lobar, and variant. Holoprosencephaly is relatively rare. The overall prevalence in a multicenter study was 1 in 13,000 to 18,000 live births. However, the presentation of holoprosencephaly with cebocephaly, micropenis, agenesis of middle phalanges of the fifth finger, and postaxial polydactyly in association with early onset preeclampsia is extremely rare...

This report of a 46,XY patient born with a micropenis consistent with etiology from isolated congenital growth hormone deficiency is used to (1) raise the question regarding what degree testicular testosterone exposure to the central nervous system during fetal life and early infancy has on the development of male gender identity, regardless of gender of rearing; (2) suggest the obligatory nature of timely full disclosure of medical history; (3) emphasize that virtually all 46,XY infants with functional testes and a micropenis should be initially boys except some with partial androgen insensitivity syndrome; and (4) highlight the sustaining value of a positive long-term relationship with a trusted physician (R...

INTRODUCTION: Hypospadias is one of the most common congenital anomalies of the penis. Previous studies reported mutation of the Wilms' tumor 1 (WT1) gene as a cause of hypospadias. The aim of this study is to describe the WT1 mutation spectrum and polymorphism in hypospadias patients in Indonesia. MATERIAL AND METHODS: DNA was isolated from 74 hypospadias patients at the Division of Pediatric Surgery, Department of Surgery Hasan Sadikin Hospital. All exons in the WT1 gene were amplified by a PCR method, followed by Sanger sequencing...

Although endocrine-disrupting chemicals (EDCs, including pesticides) are thought to increase the risk of hypospadias, no compounds have been formally identified in this context. Human studies may now be possible via the assessment of meconium as a marker of chronic prenatal exposure. The objective of the present study was to determine whether or not prenatal exposure to pesticides (as detected in meconium) constitutes a risk factor for isolated hypospadias. In a case-control study performed between 2011 and 2014 in northern France, male newborns with isolated hypospadias (n = 25) were matched at birth with controls (n = 58)...

By definition, about 2.5% of children show a short stature due to several causes. Two clinical conditions are characterized by serum IGF-I low levels, idiopathic GH deficiency (IGHD), and GH insensitivity (GHI), and the phenotypic appearance of these patients may be very similar. We studied two children with short stature and similar phenotypes. The first case showed frontal bossing, doll face, acromicria, and truncal obesity, with a GH peak <0.05 ng/ml after stimuli and undetectable serum IGF-I levels...

Background and objectives: The normal length of penis in preterm and term neonates is different among different nations, and is affected by various factors. The present study aimed to determine stretched penile length (SPL) values and cutoff level of micropenis in term and preterm Iranian neonates, for the first time. Materials and methods: All male neonates born in two general hospitals of Tehran (Akbarabadi, and Rasoul hospitals), center of Iran, with gestational age of 28-42 weeks were included and their SPL and penile circumference (PC) were examined on the first 3 days after birth by the same physician...

Idiopathic hypogonadotropic hypogonadism (IHH) is characterized by low levels of gonadotropins and delayed or absent sexual development. Most of the patients are diagnosed in late adolescence or early adulthood. Determining the diagnosis of IHH in prepubertal patients can be challenging. Making a timely, correct diagnosis has important clinical implications. Here we aimed to identify the genetic cause of IHH in three prepubertal siblings from a Chinese Han family and give appropriate treatment advice. Using whole exome sequencing (WES), we identified a novel homozygous GNRHR mutation (NM_000406; c...

Background/aim: In micropenis cases accompanied by external genital abnormalities such as hypospadias and cryptorchidism, infertility and spermatogenic failures have been reported to correlate with androgen receptor ( AR ) gene CAG and GGN repeat polymorphisms. While there is one study on isolated micropenis and CAG repeats, no study related to GGN repeats has been reported. We investigated the relation between CAG and GGN repeats in the AR gene with development of penis length in boys with isolated micropenis...
