Objective: The aim of this study were to investigate the level of inhibin B and its relationship with testosterone, anti-Müllerian factor, basal, and GnRH-stimulated gonadotropin hormones (LH and FSH) concentration in boys with constitutional delay of puberty.Material and methods: In the study were included 15 boys (mean age 14.5±1.6 years) in Tanner stages 1–2. The investigation consists of genital examination with prader orchidometer, de...

Background: Neurokinin B and kisspeptin appear to play main roles in puberty.Aims and objectives: The aim of the present study was to investigate the diagnostic role of kisspeptin and neurokinin B in central precocious puberty (CPP) and premature thelarche (PT).Methods: The girls who presented with breast development (between 5 and 8 years) were included in the study. All cases underwent bone age (BA) assesment. Basal serum FSH, LH...

Background: Leptin has a major role in the metabolic gating of pubertal maturation. Kisspeptin is an essential gatekeeper of puberty. Neurokinin B (NK B) is not widely known in the precocious puberty (PP) but it is coexpressed with kisspeptin in the arcuate nucleus and synchronizes the pulsatile secretion of kisspeptin.Objective and hypotheses: Leptin, kisspeptin, and NK B are influenced by energy balance and metabolic status has a clear impact on the ti...

Introduction and Objective: Puberty marks the transition from childhood to adulthood, initiated by the activation of the hypothalamic-pituitary-gonadal axis. Anti-Müllerian hormone (AMH) and inhibin B, both secreted by granulosa cells, play crucial roles in pubertal development and reflecting ovarian reserve. Establishing reference intervals for AMH and inhibin B across different pubertal stages is essential for assessing ovarian function and identifying ...

Although type 1 diabetes (T1D) is most common autoimmune chronic metabolic disease in childhood, data about the role of T-Lymphocytes (T-Ly) and B-Lymphocytes (B-Ly) in children after the diabetes onset are still controversial. The aim of the study was to evaluate the serum levels of T– and B-Ly in children with T1D as a predisposing factor for genital candidiasis (GC).Material: We studied 71 children with T1D at the age of 6 to 18 years, divided in...

Background: Testicular atrophy is a rare complication following inguinal hernia repair particularly in children<2 years and those with an undescended testis at highest risk> with an undescended testis. Inhibin B is secreted from the testis as a product of Sertoli cells, and has been suggested as a good marker for spermatogenesis. Its value is expected to be very low in children with bilateral testicular atrophyCase Report...

Background: Boys with delayed puberty represent one of the main cause for pediatric endocrine referrals. Although the majority of them have constitutional delay of growth and puberty (CDGP), it is important to identify isolated hypogonadotropic hypogonadism (IHH) for optimal management.Objective and hypotheses: The aim of the study was to evaluate the usefulness of inhibin B and AMH as biological markers for distinguishing between CDGP and IHH.<p cla...

Background: Cis-gender females are known to mount stronger immune responses to invading pathogens or vaccines than cis-gender males. However, this is also associated with increased risk of autoimmunity. Little is known about the immunophenotypes of transgender individuals on gender-affirming hormonal treatment, despite growing evidence that hormones influence the immune system. Via the process of class-switch recombination (CSR), B-cell immunoglobulin isotype ...

Background: Anti-Müllerian hormone (AMH) is produced by small growing ovarian follicles. It inhibits both FSH induced maturation of follicles as well as aromatase activity. Genetic variation of AMH signalling is associated with age at menopause and circulating oestradiol levels, i.e. AMH rs10407022 T>G (intragenic) and AMHR2 rs11170547 C>T (putative enhancer).Objective and hypotheses: This present study aims to investigate ...

Hypogonadism is represented by a hypo- and hypergonadotropic variant. Antymüllerian hormone (AMH) and inhibin B are used to assess ovarian reserve, but in pediatric practice their role has not been studied. The main interest is to conduct the study of ovarian reserve in hypogonadism among girls.Objective of the Research: To compare the content of inhibin B, AMH and estradiol in girls with hyper- and hypogonadotropic hypogonadism...
