The pituitary gland is significantly affected during gestation in terms of both size and function. Due to this physiologic adaptation, endocrine evaluation and interpretation of imaging is far more complex than in the non-pregnant state. Pituitary disorders are rare in pregnancy, as they are usually associated with gonadal dysfunction …

Obesity in men of reproductive age is globally on the increase. There is clear evidence from epidemiological studies that obesity impacts negatively on male fertility; it is associated with hypogonadism, although it is less consistently linked to impaired spermatogenesis and tests of sperm function, including DNA fragmentation …

OBJECTIVE: The circadian hormone melatonin has wide-reaching effects on human physiology. In adolescents, the impact of nighttime light exposure and other modifiable behavioral factors on melatonin levels is poorly understood. DESIGN: We cross-sectionally examined the influence of nighttime behaviors …

BACKGROUND: Studies concerning presentation and evolution over time of Hashimoto’s thyroiditis (HT) in children with Down’s syndrome (DS) are few, are based on limited study populations and do not include control HT groups without DS. The aim of this multicenter study was to shed further light on the relationships between DS and HT in childhood …

There is evidence demonstrating that sexual complaints represent the most specific symptoms associated with late onset hypogonadism, while central obesity is the most specific sign. In obese men, hypogonadism can further worsen the metabolic profile and increase abdominal fat …

The anabolic hormone testosterone (T) continues to be researched extensively in exercise studies, with blood serum or plasma samples collected routinely. This method is considered both valid and reliable; however, the collection process can be invasive and difficult during exercise …

OBJECTIVE: In order to gain deeper insight into molecular mechanisms underlying oxidative stress (OS) and its relation to insulin resistance and hyperandrogenemia, plasma markers of OS and antioxidant glutathione-peroxidase (GPX) activity were studied in non-obese polycystic ovary syndrome (PCOS) women via the oral glucose tolerance test …

While cancer, and especially testicular cancer and Hodgkin’s disease, affects male fertility in many ways, the current increase of survival of male cancer patients of reproductive age or earlier has emerged as a new challenge to their subsequent ability to father children. Cancer treatments, including surgery, radiotherapy and chemotherapy …

OBJECTIVE: Congenital adrenal hyperplasia (CAH) can be complicated by central precocious puberty (CPP) in children, which may compromise final height. We aimed to evaluate the effect of gonadotropin-releasing hormone analog (GnRHa) therapy on growth in children with CAH …

OBJECTIVE: Most women with PCOS have increased adrenal androgen production, enhanced peripheral metabolism of cortisol and elevation in urinary excretion of its metabolites. Increased cortisol clearance in PCOS is followed by a compensatory overdrive of the hypothalamic-pituitary-adrenocortical (HPA) axis …

OBJECTIVE: Human kallikrein-like peptidase 10 (KLK10), a serine protease, plays an important role in the regulation of cell proliferation and tumor growth. In this work, we investigated KLK10 immunoexpression in various types of surgically removed human pituitary tumors …

OBJECTIVE: Acanthosis nigricans (AN) has been closely associated with obesity. Depression has also been shown to be disproportionally prevalent among obese people. However, there is still a paucity of studies on the relationship between depressive symptoms and AN in obese patients. This study examined the difference in metabolic disorders and depressive symptoms …

An ever-increasing proportion of young males treated for cancer are cured. Therefore, one of the major challenges of modern Clinical Oncology is to ensure good quality of life. Cancer disease per se as well as cancer treatment may have a negative impact on androgen production, thereby leading to subclinical or clinically overt hypogonadism …

OBJECTIVE: To evaluate the effect of dipeptidyl-peptidase-4 (DPP-4) inhibitor vildagliptin on high sensitivity C-reactive protein (hsCRP) and arterial stiffness (AS) in patients with type 2 diabetes (T2DM). DESIGN: Sixty-four drug-naive diabetic patients, with inadequate glycemic control …

BACKGROUND: Structural defects of the hypothalamic-pituitary area in MRI are suggested as being a more accurate marker of growth hormone deficiency (GHD) than laboratory assays. OBJECTIVE: To compare auxological characteristics in GHD children with normal pituitary (NP) function and with ectopic posterior pituitary (EPP) …

Despite the variety of available female contraceptive methods, many pregnancies (~50%) are still undesired. Many men (>60%) want to participate equally with their partner in family planning; however, male contraceptive methods (MCMs) account for only 14% of those used worldwide and no pharmaceutical MCM is available so far …

OBJECTIVE: In the last few years a number of studies have found that metformin has a thyrotropin (TSH)-lowering effect in patients with type 2 diabetes (DM2) and that this effect disappears after discontinuation of the drug. Initial studies were carried out in hypothyroid patients on levothyroxine (LT4) treatment …
