Kisspeptin and Endometriosis-Is There a Link?

This article presents a narrative review that explores the potential link between kisspeptin-a key regulator of the hypothalamic-pituitary-gonadal axis-and the pathogenesis of endometriosis. Kisspeptin plays a significant role in regulating reproductive functions by modulating the release of gonadotropin-releasing hormone (GnRH), which in turn stimulates the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Recent studies suggest that kisspeptin may also impact peripheral reproductive tissues and influence inflammatory processes involved in the development of endometriosis.

Sexual health and wellbeing and the menopause: An EMAS clinical guide.

Introduction: Sexual health and wellbeing are significant aspects of quality of life. However, taking a sexual history is often avoided in medical practice, leaving a void in management and awareness. As the menopause can have a major impact on sexual health, it is imperative that healthcare providers are appropriately trained in sexual health and wellbeing and the aligned disciplines in order to achieve optimal care.

Bone: A Neglected Endocrine Organ?

Bone has traditionally been viewed in the context of its structural contribution to the human body. Foremost providing necessary support for mobility, its roles in supporting calcium homeostasis and blood cell production are often afterthoughts. Recent research has further shed light on the ever-multifaceted role of bone and its importance not only for structure, but also as a complex endocrine organ producing hormones responsible for the autoregulation of bone metabolism.

EMAS position statement: Thyroid disease and menopause.

Introduction: Thyroid diseases are common in women in their late reproductive years; therefore, thyroid disease and menopause may co-exist. Both conditions may present with a wide range of symptoms, leading to diagnostic challenges and delayed diagnosis. Aim To construct the first European Menopause and Andropause Society (EMAS) statement on thyroid diseases and menopause.

The impact of water pollution on the health of older people.

Water pollution exerts a negative impact on the health of both women and men, inducing hormonal changes, accelerating aging, and consequently leading to the premature onset of age-related health problems. Water pollutants can in general be classified as chemical (both organic and inorganic), physical, and biological agents. Certain chemical pollutants have been found to disrupt hormonal balance by blocking, mimicking, or disrupting functions within the intricate homeostasis of the human body.

Association of Obesity and Bariatric Surgery on Hair Health.

Obesity and obesity-related conditions today constitute a public health problem worldwide. Obesity is an "epidemic" chronic disorder, which is defined by the WHO as normal or excessive fat accumulation that may impair health. It is also defined for adults as a BMI that is greater than or equal to 30.

Neuroendocrine disturbances in women with functional hypothalamic amenorrhea: an update and future directions.

Functional hypothalamic amenorrhea (FHA) is one of the most common causes of both primary and secondary amenorrhea in women of reproductive age. It is characterized by chronic anovulation and the absence of menses that appear as a result of stressors such as eating disorders, excessive exercise, or psychological distress. FHA is presumed to be a functional disruption in the pulsatile secretion of hypothalamic gonadotropin-releasing hormone, which in turn impairs the release of gonadotropin.

EMAS position statement: Testosterone replacement therapy in older men.

Introduction: Late-onset hypogonadism is the clinical entity characterised by low testosterone concentrations associated with clinical symptoms in the absence of organic disease in ageing men. It has been associated with metabolic syndrome, reduced bone mineral density, and increased cardiovascular morbidity and mortality risk. Although testosterone replacement therapy (TRT) reverses most of these conditions in young hypogonadal men, the risk/benefit ratio of TRT in older men is debatable.

Do GLP-1 Analogs Have a Place in the Treatment of PCOS? New Insights and Promising Therapies.

Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy in women of reproductive age. This condition is characterized by hyperandrogenism and either oligo- or anovulation. PCOS patients often present comorbidities such as obesity, insulin resistance, impaired glucose metabolism, dyslipidemia, hypertension, metabolic syndrome, and an increased risk of diabetes.

Managing Early Onset Osteoporosis: The Impact of Premature Ovarian Insufficiency on Bone Health.

Premature ovarian insufficiency is a reproductive endocrine disorder characterized by the cessation of ovarian function before the age of 40 years. Although the etiopathology of POI remains largely unknown, certain causative factors have been identified. Individuals affected by POI are at an increased risk of experiencing bone mineral density (BMD) loss.

Polycystic Ovary Syndrome: Past, Present and Future.

Early mentions of PCOS as a disorder can be traced back to ancient history [...

Decreased neurokinin B as a risk factor of functional hypothalamic amenorrhea.

Background: Neurokinin B (NKB) belongs to the tachykinin family of proteins who's regulation is essential for proper function of the reproductive system. It has been shown that patients with functional hypothalamic amenorrhea (FHA) exhibit decreased levels of serum kisspeptin. As kisspeptin secretion is regulated by NKB signaling, it is reasonable to suspect that patients with FHA will also have abnormal NKB secretion.

Bones and Hormones: Interaction between Hormones of the Hypothalamus, Pituitary, Adipose Tissue and Bone.

The bony skeleton, as a structural foundation for the human body, is essential in providing mechanical function and movement. The human skeleton is a highly specialized and dynamic organ that undergoes continuous remodeling as it adapts to the demands of its environment. Advances in research over the last decade have shone light on the various hormones that influence this process, modulating the metabolism and structural integrity of bone.

PCOS in Adolescents-Ongoing Riddles in Diagnosis and Treatment.

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of reproductive age. A diagnosis of PCOS is established when a patient exhibits two of three Rotterdam criteria: oligoovulation or anovulation, excess androgen activity, and polycystic ovarian morphology. The pathogenesis of PCOS, as it affects adolescents, is often discussed in terms of a "two-hit" theory.

EMAS position statement: Vitamin D and menopausal health.

Introduction: There is increasing evidence that vitamin D has widespread tissue effects. In addition to osteoporosis, vitamin D deficiency has been associated with cardiovascular disease, diabetes, cancer, infections and neurodegenerative disease. However, the effect of vitamin D supplementation on non-skeletal outcomes requires clarification, especially in postmenopausal women.

Cognitive decline and dementia in women after menopause: Prevention strategies.

Worldwide, cognitive decline and dementia are becoming one of the biggest challenges for public health. The decline in cognition and the development of dementia may be caused by predisposing or trigger factors. There is no consensus over whether the drop in estrogen levels after menopause is a risk factor for cognitive decline and dementia.

Peripartum prolactin and cortisol level changes. A prospective pilot study.

Objectives: Although the role of prolactin and cortisol in the human lactation process seems to be undisputed, the changes in postpartum serum concentrations in mothers make data interpretation difficult.

Material And Methods: To determine the factors that possibly influence these hormones, we examined a group of patients who were admitted to the Gynecology-Obstetrics Clinical Hospital in Poznań for labor induction and/or in the active phase of the first labor period. The serum levels of cortisol and prolactin were assessed in these full-term pregnant women during admission to labor, in the third stage of labor, and on the second day postpartum.

The influence of estro-progestin therapy on neurohormonal activity in functional hypothalamic amenorrhea.

Functional hypothalamic amenorrhea (FHA) is a chronic endocrine disorder caused by the abnormal pulsatile secretion of neurohormones in the hypothalamus. Secretion of GnRH is regulated by kisspeptin/neurokinin B/dynorphin (KNDy) neurons. These neurons produce, among other neurohormones, neurokinin B (NKB) which regulates the coordinated stimulation or inhibition of GnRH secreting neurons.

Nesfatin-1 as a potential marker for functional hypothalamic amenorrhea.

Objective: Nesfatin-1 plays an important role in regulating metabolism, appetite, gut motility, and eating behavior. It is suspected that abnormalities in nesfatin-1 secretion may be involved in the development of anorexia nervosa, and as such, this study aims to investigate the "circumstances of" nesfatin-1 in patients with functional hypothalamic amenorrhea (FHA).

Materials And Methods: One hundred and forty-seven patients with FHA were enrolled to the present study.

Stress, kisspeptin, and functional hypothalamic amenorrhea.

Functional hypothalamic amenorrhea (FHA) is the most common cause of secondary amenorrhea in women of reproductive age. FHA is predominantly caused by stress, decreased caloric intake, excessive exercise, or a combination thereof. These physical, psychological, and metabolic stressors cause aberration in the pulsatile release of gonadotropin-releasing hormone (GnRH) and subsequently impair function of the hypothalamic-pituitary-ovarian (HPO) axis.

Neonatal breast-suckling skills in the context of lactation and peripartum hormonal changes and additional factors-a pilot study.

Background: Childbirth and lactation are intricate processes, involving several hormones, the most important of which are prolactin (a protein hormone) and cortisol (one of the glucocorticoids). The early postpartum period is crucial for both mother and newborn and has an impact on the lactation and breastfeeding process.

Methods: The study included 78 patients who were admitted to the Gynecology-Obstetrics Clinical Hospital in Poznań for labor induction and/or in the active phase of the first labor stage.

From diagnosis to treatment of androgen-secreting ovarian tumors: a practical approach.

About 5% of all ovarian tumors develop some form of hormonal activity. Only 1% of ovarian tumors will secrete androgens causing clinical hyperandrogenism. Most androgen-secreting neoplasms (ASN) derive from sex cord or stroma cells of the ovary and may affect both premenopausal and postmenopausal women.

Menopause, wellbeing and health: A care pathway from the European Menopause and Andropause Society.

This care pathway from the European Menopause and Andropause Society (EMAS) provides an updated pathway for monitoring and guidance of women at midlife, focusing on those approaching the end of the reproductive life-cycle, going through the menopausal transition and beyond. The care pathway is written by professionals involved in women's health and provides a stepwise individualized approach, stratified according to needs, symptoms and reproductive stage. Furthermore, the pathway provides details on screening for chronic diseases related to menopause and ageing.
