Sex-specific ranges and ratios for anogenital distance among Thai full-term newborns

Numsriskulrat Nattakarn , Srilanchakon Khomsak , Pronprechatham Chaiyat , Pornkunwilai Sopon , Supornsilchai Vichit

Introduction: Anogenital distance (AGD) is a useful marker of prenatal androgen exposure and a tool for assessment of differences of sex development. Normative data on AGD ranges for local references should be established as standards for comparison in clinical practice, but there is a paucity of data among newborns in Thailand.Aim: To provide the sex-specific ranges for AGD in Thai full-term newborns.<p class="abste...

Dynamic changes of reproductive hormones in male minipuberty: Temporal dissociation of Leydig- and Sertoli-cell activity

S. Busch Alexander , Lindhardt Ljubicic Marie , N Upners Emmie , Bistrup Fischer Margit , Lau Raket Lars , Frederiksen Hanne , Albrethsen Jakob , Holm Johannsen Trine , P Hagen Casper , Juul Anders

Background: The male Hypothalamic-Pituitary-Gonadal (HPG) axis is transiently active during the first months of life with surging serum concentrations of reproductive hormones. This period, termed minipuberty, promotes masculinization, including testicular, and penile growth, as well as further testicular descent in males. It appears to be essential for priming specific cell types, i.e. Sertoli-, Leydig-, and germ cells, including subsequent growth and maturat...

Reference intervals of serum estradiol during childhood: comparing and reviewing five studies, effects of gender and age

Lamprecht Tabea , Reinehr Thomas , Kleber Michaela , Rothermel Juliane , Schulz Esther , Simic-Schleicher Gunter , Heger Sabine , Holterhus Paul-Martin , Kulle Alexandra

Background: Specific measurement of low serum / plasma concentrations of 17β-estradiol (E2) is important in pre-pubertal and pubertal children in routine paediatric endocrinology. However, there is still a gap in available reference intervals (RIs) for E2 in paediatrics. The study was partially funded by the German Ministry of Health, grant number 2519FSB503.Objective: First, we technically developed a highly sensit...

Gutierrez Marcela , Soria Marcela , Morán Lorena , Ferraro Cristina , Bedecarrás Patricia , Drelichman Guillermo , Aversa Luis , Bergadá Ignacio , A. Rey Rodolfo , P. Grinspon Romina

Aim: To determine Sertoli cell function at diagnosis and after 3 months of chemotherapy.Methods: A prospective cohort study was performed including children with acute lymphoblastic leukaemia, acute myeloid leukaemia, or non-Hodgkin lymphoma. Serum levels of AMH were evaluated at diagnosis and after 3 months during chemotherapy. Results were analysed as standard deviation scores according to pubertal stage and expressed ...

The effect of GnRHa and testosterone treatment on growth in trans boys

Willemsen Lieve , Boogers Lidewij , Wiepjes Chantal , van Trotsenburg Paul , Klink Daniel , den Heijer Martin , Hannema Sabine

Background: Pubertal growth and adult height are important to many transgender adolescents undergoing medical transition. However, few studies are available on the impact of puberty suppression (PS) with GnRH analogues (GnRHa) and hormonal therapy (HT) with testosterone on growth. In this longitudinal cohort study, we investigated the effect of PS and HT on growth and adult height in transgender boys.Methods: A total of ...

Differently Normal: Making sense of Adolescent Perspectives of Early Childhood Experiences associated with Congenital Adrenal Hyperplasia (CAH)

Siese Thomas , Alderson Julie , Hickingbotham Hannah , Hawton Katherine , Skae Mars , Crowne Elizabeth

Background: There is limited reporting of the impact of genital difference on early childhood experience, although the young person’s viewpoint should be at the core of patient centred clinical decision making. The experience of girls living with Congenital Adrenal Hyperplasia (CAH) may differ according to context, being influenced by interactions within the family, with specialist teams as well as prevailing social values. Clearly there is a need to inv...
