Purpose: Since inhibin B is the endocrine marker of spermatogenesis, basal inhibin B levels may reflect germ cell status in children. The aims of this study were to determine the changes in endocrine parameters after orchiopexy in patients with cryptorchidism and to compare these findings with testicular biopsy parameters.
Materials And Methods: A total of 27 boys with undescended testis were included in this study. Inguinal orchiopexy was performed in all patients and 15 underwent testicular biopsy at orchiopexy. Spermatogonia per tubular transverse section and fertility index values were determined. Before and 6 months after orchiopexy serum basal inhibin B and other serum hormone levels were measured in all patients.
Results: Mean serum basal inhibin B levels significantly increased 6 months after successful orchiopexy (p = 0.001). However, inhibin B level did not increase in patients who had a low testicular biopsy score. Other reproductive hormone levels did not change after orchiopexy.
Conclusions: Basal inhibin B level could be used as a followup parameter after orchiopexy. If basal inhibin B level does not increase in the postoperative period, the amount of germ cells in the testis may be too low or the orchiopexy might not have been implemented appropriately.

Pubertal disorders in the form of delayed puberty (DP) or precocious puberty (PP) can cause considerable anxiety to both children and parents. Since the clinical and biochemical signatures of self-limiting and permanent conditions overlap considerably, it can be hard to determine whether to offer them reassurance or intervention. Researchers have thus long been searching for a robust test to indicate that the process of endogenous puberty is underway and is likely to proceed to completion.

Introduction: This study aimed to distinguish isolated hypogonadotropic hypogonadism (IHH) from constitutional delay in growth and puberty (CDGP) by various hormonal tests in both sexes.
Methods: Boys with testicular volume (TV) <4 ml (14-18 years) and girls with breast B stage (13-18 years) were enrolled in this study. A detailed history, clinical examination and hormonal analysis including basal luteinising hormone (LH), follicle-stimulating hormone (FSH), inhibin B, anti-Mullerian hormone (AMH), testosterone (boys), oestradiol (girls), triptorelin stimulation test and 3-day human chorionic gonadotropin (HCG) stimulation test (boys) were performed.

Objective: To evaluate the role of basal and follicle-stimulating hormone (FSH)-stimulated inhibin B in differentiating premature thelarche from gonadotropin-dependent precocious puberty (GDPP).
Methods: This was a prospective interventional study. Basal and FSH-stimulated inhibin B levels were estimated in girls presenting with thelarche < 8 years age (n = 10), healthy girls with normal pubertal development (pubertal control) (n = 8) and healthy prepubertal girls (prepubertal control) (n = 7).

Unlabelled: Single-cell transcriptomics studies have begun to identify breast epithelial cell and stromal cell specific transcriptome differences between BRCA1/2 mutation carriers and non-carriers. We generated a single-cell transcriptome atlas of breast tissues from BRCA1, BRCA2 mutation carriers and compared this single-cell atlas of mutation carriers with our previously described single-cell breast atlas of healthy non-carriers. We observed that BRCA1 but not BRCA2 mutations altered the ratio between basal (basal-myoepithelial), luminal progenitor (luminal adaptive secretory precursor, LASP), and mature luminal (luminal hormone sensing) cells in breast tissues.
