Ovarian and Adrenal Hyperandrogenism

2007

Because in normal women androgens are secreted in almost equal quantities by both adrenals and ovaries, for many years many studies have tried to distinguish the source of androgen excess. However, in the last 10-15 years, the diagnoses of ovarian or adrenal hyperandrogenism have almost disappeared. This is due to the lack of specificity of dynamic tests as well as to the emphasis given on clinical information and ovarian sonography for the diagnosis of hyperandrogenic syndromes. However, determination of the source of increased androgens may still be useful for improving the classification and the understanding of androgen excess disorders. The aim of this review is to examine the source o…

Ovarian cysts in newborns.

2001

Before the introduction of ultrasonography (US), ovarian cysts in newborns were thought to be rare. With the extended use of real-time US, prenatal detection has increased. There is still considerable controversy regarding the best treatment of these neonatal findings. A total of 27 instances in 24 consecutive newborns of antenatally-diagnosed ovarian cysts were reviewed for US data, management, and outcome to assess the ante- and postnatal evolution of the cyst and establish appropriate therapy. The cysts detected during pregnancy were studied by repeated postnatal US studies. In 10 children (2 with bilateral cysts) the cyst evolved spontaneously toward regression. Fourteen patients were o…

Does hysterectomy with ovarian conservation affect bone metabolism and density?

2002

We evaluated whether hysterectomy with ovarian conservation (HYX) has an effect on bone metabolism and density in 176 healthy Caucasian postmenopausal women aged 48-59 years. Bone properties of the hip, spine, radius, tibia, and calcaneus were measured using different bone assessment modalities. In addition, bone turnover was assessed using serum bone-specific alkaline phosphatase (BAP), osteocalcin (OC), and tartrate-resistant acid phosphatase (TRAP) 5b as biomarkers. Our results showed that women having HYX had a significantly lower level of OC ( P = 0.017) and a marginally lower level of TRAP 5b ( P = 0.051) and higher bone mineral density (BMD) of the femoral neck ( P = 0.037) and lumba…

Diet to Reduce the Metabolic Syndrome Associated with Menopause. The Logic for Olive Oil

2020

The rates of metabolic syndrome are increasing in parallel with the increasing prevalence of obesity, primarily due to its concomitant insulin resistance. This is particularly concerning for women, as the years around menopause are accompanied by an increase in visceral obesity, a strong determinant of insulin resistance. A fall in estrogens and increase in the androgen/estrogen ratio is attributed a determining role in this process, which has been confirmed in other physiological models, such as polycystic ovary syndrome. A healthy lifestyle, with special emphasis on nutrition, has been recommended as a first-line strategy in consensuses and guidelines. A consistent body of evidence has ac…

Photoperiodic regulation of life-history traits before and after eclosion: egg-to-adult development time, juvenile body weight and reproductive diapa…

2012

Photoperiod is the main environmental cue used by northern insects to predict the forthcoming seasonal changes and to adjust their life-history traits to fit these changes. We studied the effects of photoperiod on egg-to-adult development time, juvenile body mass and female reproductive diapause in two northern Drosophila montana populations with different patterns of voltinism. The most interesting findings were consistent between the populations: (1) when maintained before eclosion in short day conditions, representing early autumn, the flies developed faster and were lighter than when maintained in long day conditions, representing early summer, (2) photoperiodic time measurement is appa…

Endothelial abnormalities in young women with PCOS: correlations with insulin resistance and decreased levels of serum adiponectin

2006

Abstract PURPOSE: Polycystic ovary syndrome (PCOS) is an extremely prevalent disorder in which elevated blood markers of cardiovascular risk and altered endothelial function have been found. This study was designed to determine if abnormal carotid intima-media thickness (IMT) and brachial flow-mediated dilation (FMD) in young women with PCOS may be explained by insulin resistance and elevated adipocytokines. METHODS: A prospective study in 50 young women with PCOS (age: 25.2 +/- 1 years; body mass index [BMI]: 28.7 +/- 0.8) and 50 matched ovulatory controls (age: 25.1 +/- 0.7 years; BMI: 28.5 +/- 0.5) was performed. Carotid IMT, brachial FMD, and blood for fasting glucose, insulin, leptin, …

Long-Term Data Reveal the Associations of the Egg Quality With Abiotic Factors and Female Traits in the Baltic Herring Under Variable Environmental C…

2021

In fish, the lipid resources of the female form a link between the environment and progeny, contributing to the contents of the egg yolk. Variation of the environmental conditions is therefore expected to affect the egg quality via maternal pathways, reflecting the female’s response to the environmental factors before spawning. We investigated the content of lipids and thyroid hormones in the ovary and eggs of the Baltic herring during 1988–2019, when salinity of the Baltic Sea first declined and then stabilized to a lower level, and winters varied between severe and mild. The total lipid resources of spawning females decreased by 40–50% during the study, and the ovarian lipid concentration…
