BACKGROUND: Multidisciplinary management of Klinefelter cases is now considered good clinical practice in order to ensure optimal quality of life. Reproductive performance of Klinefelter men is an important issue however literature in this domain is limited and prone to bias. STUDY DESIGN: This was a retrospective longitudinal cohort study performed at a tertiary referral University Centre for Reproductive Medicine and Genetics. One hundred thirty-eight non-mosaic azoospermic Klinefelter patients undergoing their first testicular biopsy (TESE) between 1994 and 2013, followed by intracytoplasmic sperm injection (ICSI) with fresh or frozen-thawed testicular sperm in the female partner, were followed-up longitudinally...

BACKGROUND: Approximately 1 in 650 boys are born with an extra X chromosome. Boys and men with 47,XXY (Klinefelter syndrome) are at risk for neurodevelopmental disorders and specific cognitive impairments. This study was focused on social anxiety and social cognition. The aim was to assess if these aspects of the phenotype are related to testosterone deficiency, which is typically seen in 47,XXY from puberty onwards. METHODS: In the study 20 boys with 47,XXY and 25 non-clinical controls between 8 and 19 years participated...

Focal dermal hypoplasia (FDH, Goltz syndrome, MIM: #305600) constitutes a rare multisystem genetic disorder of the skin, skeleton, teeth and eyes with considerable variation in the clinical features. FDH is transmitted as an X-linked dominant trait and is caused by mutations in PORCN. In males, hemizygous PORCN mutations are lethal in utero. Around 300 cases have been reported in the literature to date. About 10% of them are males presenting either Klinefelter syndrome (karyotype 47, XXY) or mosaicism of a postzygotic mutation...

Incontinentia pigmenti (IP) is an X-linked dominant neurocutaneous syndrome with ophthalmologic, neurologic, cutaneous, and dental manifestations and in most cases antenatally lethal in boys. Occasionally, typical IP may occur in boys due to Klinefelter syndrome or a genomic mosaicism. Skin lesions are observed in 4 stages: blistering, verrucous linear plaques, swirling macular hyperpigmentation, followed by linear hypopigmentation that develop during adolescence and early adulthood. Neonatal herpes simplex virus (HSV) infection can be manifested in 3 forms: localized, disseminated, and central nervous system (CNS) involvement...

BACKGROUND AND OBJECTIVE: Klinefelter Syndrome (KS) is the most common sex chromosome aneuploidy (47,XXY) and cause of male hypergonadotropic hypogonadism. It is characterized by an extreme clinical heterogeneity in presentation, including infertility, hypogonadism, language delay, metabolic comorbidities, and neurocognitive and psychiatric disorders. Since testosterone is known to have organizational, neurotrophic and neuroprotective effects on brain, the condition of primary hypogonadism could play a role...

Constitutional delay of growth and puberty (CDGP) is the most common cause of delayed puberty (DP), is mainly found in males, and is characterized by short stature and delayed skeletal maturation. A family history of the subject comprising the timing of puberty in the parents and physical examination may provide clues regarding the cause of DP. Delayed onset of puberty is rarely considered a disease in either sex. In fact, DP usually represents a common normal variant in pubertal timing, with favorable outcomes for final height and future reproductive capacity...

BACKGROUND: Short foetal femur length (FL) is a normal variant but may also be a marker for disorders such as skeletal dysplasia, Trisomy 21 (T21), Turners syndrome, congenital infection (TORCH) and foetal growth restriction (FGR). AIM: Our aim was to review outcomes in our population following a diagnosis of isolated short FL (FL <5th centile) when detected at the time of mid trimester foetal anomaly scan (FAS). METHODS: All women within NHS Tayside who attended for routine mid trimester foetal anomaly scan at 18-21 weeks gestation (Range = 18+2 -21+3  weeks) between November 2011 and June 2016 were included...

Heterozygous de novo or inherited pathogenic variants in the PCDH19 gene cause a spectrum of neurodevelopmental features including developmental delay and seizures. PCDH19 epilepsy was previously known as "epilepsy and mental retardation limited to females", since the condition almost exclusively affects females. It is hypothesized that the co-existence of two populations of neurons, some with and some without PCDH19 protein expression, results in pathologically abnormal interactions between these neurons, a mechanism also referred to as cellular interference...

Klinefelter syndrome (KS) and undescended testes (UDT) are known etiologies for non-obstructive azoospermia (NOA), and coexistence of both etiologies is not uncommon. Patients with both KS and a history of UDT are therefore considered to have extremely reduced chances for paternity. We aimed to analyze the impact of previous surgically corrected unilateral or bilateral UDT on sperm retrieval rates (SRRs) by microsurgical testicular sperm extraction (mTESE) in azoospermic men with KS. Age, testicular volumes, and hypothalamo-pituitary-gonadal axis function were investigated in relation to SRRs in 29 non-mosaic KS patients (47,XXY) with a history of UDT (group 1) who underwent mTESE between 2008 and 2016 in our center and compared to the data of age- and serum testosterone-matched non-mosaic KS controls with eutopic testes at birth (group 2), and to those of 51 men with NOA and a normal male karyotype (46,XY), but previous UDT (group 3)...

Context: Klinefelter syndrome (KS) is a common genetic condition in which males have an extra X chromosome. KS is associated with testosterone deficiency, neurodevelopmental delays, and cardiometabolic disorders. There has been recent interest in prepubertal androgen treatment, however the effects on puberty and gonadal function are unknown. Objective: To compare onset of puberty and testicular function in pre-pubertal boys treated with two years of oxandrolone versus placebo...

OBJECTIVE: Case reports have suggested an increased risk of gynecomastia with HMG-CoA reductase inhibitors (ie, statins). A recent meta-analysis also found that statins decrease circulating testosterone levels in men. We investigated whether statin use was associated with an increased risk of gynecomastia. DESIGN: Case-control study. PATIENTS: A cohort of patients from a random sample of 9 053 240 US subjects from the PharMetrics Plus™ health claims database from 2006 to 2016 was created...

CONTEXT: The early activation of the hypothalamic-pituitary-gonadal axis during infancy can be used in the evaluation of infants suspected of disorders of sex development (DSD). However, few data exists on sex-specific reference ranges for these hormones during early life. OBJECTIVE: To evaluate sex-differences in reproductive hormone concentrations in serum from healthy infants in order to define sex-specific cut-off values and to apply these in infants with DSD...

Gender Dysphoria is characterized by a marked incongruence between the cerebral sex and biological sex. To investigate the possible influence of karyotype on the etiology of Gender Dysphoria we carried out the cytogenetic analysis of karyotypes in 444 male-to-females (MtFs) and 273 female-to-males (FtMs) that attended the Gender Identity Units of Barcelona and Málaga (Spain) between 2000 and 2016. The karyotypes from 23 subjects (18 MtFs and 5 FtMs) were also analysed by Affymetrix CytoScan™ high-density (HD) arrays...

Spermatozoa have occasionally been identified in ejaculate of adult Klinefelter syndrome (KS) patients but very exceptionally in KS adolescents. Spermatozoa can also be retrieved in testicular tissue of KS adolescents. The testis may also harbor spermatogonia and noncompletely differentiated germ cells. Neither clinical features nor hormonal parameters could predict germ cell recovery in KS adults or adolescents. No predictive factors can actually demonstrate that early diagnosis of KS would allow increasing the chance of sperm retrieval even if it has been suggested that semen quality may decline with age in KS patients...
