The purpose of this study was to evaluate the reproductive status and clarify the reproductive physiology of captive Sichuan golden monkeys. The concentrations of urinary estradiol-3-glucuronide (E2G) and pregnanediol-glucuronide (PdG) or fecal estradiol-17β (E2) and PdG in two females, and fecal testosterone concentrations in a male, were measured continuously using enzyme immunoassays. On the basis of these hormone profiles, the follicular phase, luteal phase, and ovarian cycle were calculated to be 14.7 ± 4...

INTRODUCTION: Iodine deficiency is a global public health problem which is particularly noticeable in pregnant or breastfeeding women and their children. Even mild iodine deficiency during pregnancy can lead to damage to the developing brain and thus affecting the fetus intelligence, his cognitive and neurological function, embryogenesis and growth. PATIENTS: In the period 2010-2015 was determined by spectrophotometry at the Institute of Endocrinology the basal urinary iodine in 532 pregnant women at the age of 32 ± 5 (18-44) years, which came from Prague, Hradec Kralove and Mlada Boleslav...

BACKGROUND: Polycystic ovarian syndrome (PCOS) is one of the most common reproductive endocrinology abnormalities, and affects 5% to 10% of women of reproductive age. Western medicines, such as oral contraceptives, insulin sensitizers and laparoscopic ovarian drilling (LOD), have been used to treat PCOS. Recently, many studies have been published that consider Chinese herbal medicine (CHM) as an alternative treatment for women with PCOS. OBJECTIVES: To assess the efficacy and safety of CHM for subfertile women with PCOS...

Maternal vascular adaptation to pregnancy is critically important in order to expand the capacity for blood flow through the uteroplacental unit to meet the needs of the developing fetus. Failure of the maternal vasculature to properly adapt can result in hypertensive disorders of pregnancy such as preeclampsia (PE). Herein, we review the endocrinology of maternal adaptation to pregnancy and contrast this with that of PE. Our focus is specifically on those hormones with directly impact endothelial cell function and dysfunction, as endothelial cell dysfunction is a hallmark of PE...

OBJECTIVE: Corifollitropin alfa is a good choice for assisted reproductive technology (ART) cycles because fewer injections are needed than with other agents. In this retrospective cohort, we analyzed luteal injected half-dose depot gonadotropin hormone-releasing hormone (GnRH) agonist cycles in women who received corifollitropin alfa and those who underwent a conventional corifollitropin alfa cycle with a GnRH antagonist. MATERIAL AND METHODS: In this retrospective cohort, we analyzed luteal injected half-dose depot GnRH agonist cycles in women who received corifollitropin alfa and those who underwent a conventional corifollitropin alfa cycle with a GnRH antagonist at the Division of Reproductive Endocrinology and IVF Unit, Obstetrics and Gynecology Department, Başkent University School of Medicine, Adana, Turkey, from March 2014 to August 2015...

: Transplantation of cryopreserved ovarian tissue has been shown to successfully induce pregnancies. Furthermore, puberty may be induced by transplanted ovarian tissue in girls suffering from premature primary ovarian insufficiency (PPOI) due to gonadotoxic therapy. Therefore, the question arises if ovarian tissue cryopreservation should be recommended for puberty induction in prepubertal girls with cancer prior to gonadotoxic therapies. Although this strategy seems to be more natural than administering exogenous steroid sex hormones, there are some disadvantages from the endocrinological point of view...

INTRODUCTION: Benign prostatic hyperplasia (BPH) is generally common in men older than 50 years of age but is extremely rare in childhood. In the literature to date, fewer than five cases have been reported under 18 years of age. Owing to the limited number of cases, the etiology and management of BPH in the first two decades is not clear. OBJECTIVE: We herein report a 17-year-old boy who presented with acute urinary retention due to BPH and was treated with endoscopic transurethral resection of the prostate (TUR-P)...

BACKGROUND: Graves' disease can be treated with antithyroid drugs (ATDs), radioiodine or surgery. Use of definitive treatments (radioiodine or surgery) varies widely across centres. Specific clinical circumstances, local facilities, patient and clinician preferences and perceptions will affect the choice of treatment. Detailed understanding of UK clinicians' views and their rationale for different treatments is lacking. AIMS: To study the preferences and perceptions of UK clinicians on the role of surgery and radioiodine in the management of Graves' disease...

BACKGROUND: Patients suffering from Graves' disease (GD) are quite frequent in endocrine clinical practice. In particular, overt hyperthyroidism may be complicated by serious adverse events and requires careful treatment, but its management has changed over the years in both the USA and European Union (EU). OBJECTIVES: To evaluate the current diagnosis and management of patient's with GD in Italy, and compare results with those obtained in previous similar surveys in the USA and EU...

Thyroid cancer is the second most common cancer diagnosed during pregnancy after breast cancer. The goal of management is to control malignancy and prevent maternal and fetal complications as a result of maternal hypothyroidism. The role of female sex hormones as an etiologic factor was investigated, with no clear association. Pregnancy can cause an increase in size of a previously existed thyroid nodule through the structural similarity between TSH and BHCG, and the normally expressed estrogen receptors on thyroid gland cells...

Endocrine disruptions may be important in patients experiencing recurrent pregnancy loss (RPL). This review focuses on data available on RPL and the endocrine system to investigate relevant, and perhaps modifiable, endocrine factors of importance for the disorder. Evidence indicates that some hormones may be important as immune modulators and a better understanding of this interplay has potential for improving pregnancy outcome in RPL. To date there is a lack of consensus on the effect of endocrine treatment options in RPL and there is a strong need for large randomized-controlled trials...

BACKGROUND: Treatment options for Graves' disease (GD), namely anti-thyroid drugs (ATD), surgery or radioiodine (RAI), have not changed over the past two decades. There is no 'gold-standard' treatment for GD. AIMS: To assess whether the management of GD in New Zealand has changed since the previous 1991 New Zealand survey and compare current management with that of contemporary international studies. METHODS: We conducted an online survey of New Zealand physicians currently practising internal medicine, diabetes and/or endocrinology, using the cases and questions from the original European and 1991 New Zealand studies...

A severe gonadotropin deficiency together with chronic estradiol deficiency leading to amenorrhea characterizes patients suffering from hypogonadotropic hypogonadism. Administration of both follicle-stimulating hormone (FSH) and luteinizing hormone (LH) to these patients has been shown to be essential in achieving successful stimulation of follicular development, ovulation, and rescue of fertility. In recent years, the availability of both recombinant FSH (rFSH) and recombinant LH (rLH) has provided a new therapeutic option for the stimulation of follicular growth in hypopituitary-hypogonadotropic women (World Health Organization Group I)...

Hidradenitis suppurativa / acne inversa (HS) is a chronic inflammatory, debilitating skin disorder with a largely unknown etiology. However, many observations such as the typical onset of the disease after puberty, the female predominance, the pre-menstrual flare ups and the improvement during pregnancy suggest a contribution of endocrinological factors to the emergence of the disease. In addition, the reported efficacy of anti-androgen treatment on HS indicates a possible involvement of androgens in the pathogenesis...

Differentiation of the mammary gland during pregnancy and the first several days following parturition is required for the establishment of a normal lactation. The expansion and development of the secretory compartment into lobuloalveloar structures that secrete milk is a complex process that is under the tight control of an array of hormones and growth factors that interact at multiple levels. Of the many factors that are required to orchestrate functional differentiation during pregnancy, insulin is often overlooked...

Thyroid hormones are essential developmental factors, and Graves' disease (GD) may severely complicate a pregnancy. This review describes how pregnancy changes the risk of developing GD, how early pregnancy by several mechanisms leads to considerable changes in the results of the thyroid function tests used to diagnose hyperthyroidism, and how these changes may complicate the diagnosing of GD. Standard therapy of GD in pregnancy is anti-thyroid drugs. However, new studies have shown considerable risk of birth defects if these drugs are used in specific weeks of early pregnancy, and this should be taken into consideration when planning therapy and control of women who may in the future become pregnant...

Great controversies and misunderstandings have developed around the relatively recently coined term disorders of sex development (DSD). In this article, we question the wisdom of including XX individuals with congenital adrenal hyperplasia (CAH) in the DSD category and develop arguments against it based on the published literature on the subject. It is clear that females with CAH assigned the female gender before 24 months of age and properly managed retain the female gender identity regardless of the Prader grade...
