INTRODUCTION: Both overt and subclinical hypothyroidism are often accompanied by sexual dysfunction. Despite improving male sexual functioning, levothyroxine treatment does not always restore all its aspects. The aim of this study was to compare male sexual functioning and depressive symptoms between men with hypothyroidism receiving levothyroxine/liothyronine combination therapy and men receiving levothyroxine alone. MATERIAL AND METHODS: The study population consisted of 21 young levothyroxine-treated men with clinical symptoms of hypothyroidism in whom serum thyrotropin and thyroid hormone levels were within the normal limits...

OBJECTIVES: The aim of this study was to investigate the effect of carbamazepine (CBZ) and sodium valproate (VPA) monotherapy on sexual functions, sex hormones, and semen analysis and quality in male patients with epilepsy. METHODS: A total of 59 male patients with epilepsy, of which 30 were on VPA monotherapy and 29 were on CBZ monotherapy, were included in the study between January 2015 and March 2016. A control group was established with 30 healthy males. Luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin (PRL), free testosterone (fT), estradiol (E2), sex hormone-binding globulin (SHBG) levels and bioactive testosterone (BAT)/bioactive estradiol (BAE), and BAT/LH ratio were studied in groups...

Access to effective affordable contraception for women is critical for individual and public health. A wide range of hormonal contraceptives (HCs) which differ in the composition, concentration of progestin component, frequency of dosage and method of administration, is currently available globally. However, the options are rather limited in settings with restricted economic resources that frequently overlap with areas of high HIV-1 prevalence. The predominant contraceptive used in Sub-Saharan Africa is the progestin-only three-monthly injectable depo-medroxyprogesterone acetate (DMPA)...

There is a substantial unmet clinical need for new strategies to protect the hematopoietic stem cell (HSC) pool and regenerate hematopoiesis after radiation injury from either cancer therapy or accidental exposure. Increasing evidence suggests that sex hormones, beyond their role in promoting sexual dimorphism, regulate HSC self-renewal, differentiation, and proliferation. We and others have previously reported that sex-steroid ablation promotes bone marrow (BM) lymphopoiesis and HSC recovery in aged and immunodepleted mice...

A bulk of literature demonstrated that respiratory allergy, and especially asthma, is prevalent in males during childhood, while it becomes more frequent in females from adolescence, i.e., after menarche, to adulthood. The mechanisms underlying the difference between females and males are the effects on the immune response of female hormones and in particular the modulation of inflammatory response by estrogens, as well as the result of the activity of various cells, such as dendritic cells, innate lymphoid cells, Th1, Th2, T regulatory (Treg) and B regulatory (Bregs) cells, and a number of proteins and cytokines, which include interleukin (IL)-4, IL-5, IL-10, and IL-13...

BACKGROUND: Leydig cell hypoplasia (LCH) is a rare disease and one of the causes of male disorder of sexual differentiation (DSD). Inactivating mutations in the luteinizing hormone/chorionic gonadotropin receptor (LHCGR) gene account for the underlying LCH pathogenicity. This study aimed to analyze the clinical presentation and diagnosis as well as highlight the molecular characteristics of a subject with LCH type 1. CASE PRESENTATION: Clinical data were collected from the subject and analyzed...

Soy is a basic food ingredient of traditional Asian cuisine used for thousands of years. In Western countries, soybeans have been introduced about a hundred years ago and recently they are mainly used for surrogate foods production. Soy and soy foods are common nutritional solutions for vegetarians, due to their high protein content and versatility in the production of meat analogues and milk substitutes. However, there are some doubts about the potential effects on health, such as the effectiveness on cardiovascular risk reduction or, conversely, on the possible disruption of thyroid function and sexual hormones...

Some hypothalamic neurons expressing estrogen receptor α (Esr1) are thought to transmit a gonadal estrogen feedback signal to gonadotropin releasing hormone 1 (GnRH1) neurons, which is the final common pathway for feedback regulation of reproductive functions. Moreover, estrogen-sensitive neurons are suggested to control sexual behaviors in coordination with reproduction. In mammals, hypothalamic estrogen-sensitive neurons release the peptide Kisspeptin and regulate GnRH1 neurons. However, a growing body of evidence in non-mammalian species casts doubt on the regulation of GnRH1 neurons by Kisspeptin neurons...

BACKGROUND: In women, low sexual desire and/or sexual arousal can lead to sexual dissatisfaction and emotional distress, collectively defined as female sexual interest/arousal disorder (FSIAD). Few pharmaceutical treatment options are currently available. AIM: To investigate the efficacy and safety of 2 novel on-demand pharmacologic treatments that have been designed to treat 2 FSIAD subgroups (women with low sensitivity for sexual cues and women with dysfunctional over-activation of sexual inhibition) using a personalized medicine approach using an allocation formula based on genetic, hormonal, and psychological variables developed to predict drug efficacy in the subgroups...

REVIEW
Olivia Le Moëne, Anders Ågmo
Sexual attraction has two components: Emission of sexually attractive stimuli and responsiveness to these stimuli. In rodents, olfactory stimuli are necessary but not sufficient for attraction. We argue that body odors are far superior to odors from excreta (urine, feces) as sexual attractants. Body odors are produced by sebaceous glands all over the body surface and in specialized glands. In primates, visual stimuli, for example the sexual skin, are more important than olfactory. The role of gonadal hormones for the production of and responsiveness to odorants is well established...

Several recent longitudinal studies have investigated the hormonal correlates of both young adult women's general sexual desire and, more specifically, their desire for uncommitted sexual relationships. Findings across these studies have been mixed, potentially because each study tested only small samples of women (Ns = 43, 33, and 14). Here we report results from a much larger (N = 375) longitudinal study of hormonal correlates of young adult women's general sexual desire and their desire for uncommitted sexual relationships...

OBJECTIVE: Vulvovaginal atrophy (VVA) is a condition frequently observed in menopause. Its symptoms can significantly affect the quality of life of patients. Since VVA is related to estrogen deficiency, chemotherapy and hormone therapy for breast cancer (BC) might cause VVA by inducing menopause. Given the lack of effective treatment for VVA in BC survivors, we retrospectively evaluated the efficacy and tolerability of fractional microablative CO2 laser therapy in these patients. METHODS: We treated 82 BC survivors with three cycles of CO2 laser after failure of topical nonestrogenic therapy...

Major salivary glands play a role not only in digestion, but also in regulation of other functions in rodents. In this review, we analyzed and summarized the data about the rodents' parotid, submandibular and sublingual salivary glands functions, which is not limited to the production of saliva and action of its hydrolytic enzymes on food in the oral cavity. In recent decades significantly expanded understanding of major salivary glands nondigestive functions. They are involved in excretion of metabolic products, maintaining fluid and electrolyte balance...

In rodents, experimentally-induced ovarian hormone deficiency increases adiposity and adipose tissue (AT) inflammation, which is thought to contribute to insulin resistance and increased cardiovascular disease risk. However, whether this occurs in a translationally-relevant large animal model remains unknown. Herein, we tested the hypothesis that ovariectomy would promote visceral and perivascular AT (PVAT) inflammation, as well as subsequent insulin resistance and peripheral vascular dysfunction in female swine...

Organismal lifespan is highly plastic in response to environmental cues, and dietary restriction (DR) is the most robust way to extend lifespan in various species. Recent studies have shown that sex also is an important factor for lifespan regulation; however, it remains largely unclear how these two factors, food and sex, interact in lifespan regulation. The nematode Caenorhabditis elegans has two sexes, hermaphrodite and male, and only the hermaphrodites are essential for the short-term succession of the species...
