Attention-deficit/hyperactivity disorder (ADHD) is a very common psychiatric disorder across the life cycle and frequently presents comorbidities. Since ADHD is highly heritable, several studies have focused in the underlying genetic factors involved in its etiology. One of the major challenges in this search is the phenotypic heterogeneity, which could be partly attributable to the sexual dimorphism frequently seen in psychiatric disorders. Taking into account the well-known sexual dimorphic effect observed in serotonergic system characteristics, we differentially tested the influence of HTR1B SNPs (rs11568817, rs130058, rs6296 and rs13212041) on ADHD susceptibility and on its major comorbidities according to sex...

The ventral tegmental area (VTA) dopamine system is important for reward, motivation, emotion, learning, and memory. Dysfunctions in the dopamine system are linked to multiple neurological and neuropsychiatric disorders, many of which present with sex differences. Little is known about the extent of heterogeneity in the basic organization of VTA dopamine neurons with regard to sex. Here, we characterized the cell-specific connectivity of VTA dopamine neurons, their mRNA translational profile, and basic electrophysiological characteristics in a common strain of mice...

Potassium (K) deficiency causes a series of physiological and metabolic disorders in plants, and dioecious species exhibit different responses based on gender. Our previous morphological and physiological observations indicated that Populus cathayana males were more tolerant to K(+) deficiency than females. To continue this work, comparative transcriptome analyses were carried out to investigate sexually differential expressed genes (DEGs) in this study. The results indicate that 10 weeks of K(+) deficiency result in 111 and 181 DEGs in males and females, respectively...

The process of sexual differentiation is central for the reproduction of almost all metazoan, and therefore for the maintenance of multicellular organisms. In sex development, we can distinguish two different processes¸ sex determination, the l decision directing the undifferentiated embryo into a sexually dimorphic individual. In mammals, sex determination equals gonadal development. The second process, sex differentiation, takes place once factors produced by the gonads determine the development of the phenotypic sex...

Subject Compared to other illicit drugs Methamphetamine (MethA) is used more frequently by women than by men. Assuming the biopsychosocial etiology model, the dependency is based on several factors in which women and men differ significantly. Systematic gender-differentiated knowledge is missing until today. Method Based on a database research (PUBMED) the review examines biological, social and psychological as well as therapeutic aspects in MethA-dependent women. Results MethA-induced cognitive disturbance appear to have severer manifestations in women than in men...

Major depressive disorder (MDD) is a leading cause of disease burden worldwide. While the incidence, symptoms and treatment of MDD all point toward major sex differences, the molecular mechanisms underlying this sexual dimorphism remain largely unknown. Here, combining differential expression and gene coexpression network analyses, we provide a comprehensive characterization of male and female transcriptional profiles associated with MDD across six brain regions. We overlap our human profiles with those from a mouse model, chronic variable stress, and capitalize on converging pathways to define molecular and physiological mechanisms underlying the expression of stress susceptibility in males and females...

Fears of sexually harming children are fairly common among clients suffering from obsessive-compulsive disorder (OCD), yet these symptoms are largely unrecognized and frequently misdiagnosed by mental health professionals. Specifically, clients with pedophilia-themed OCD (P-OCD) experience excessive worries and distressing intrusive thoughts about being sexually attracted to, and sexually violating, children. Expressing these concerns may provoke misjudgments from uninformed mental health professionals that a client is presenting instead with pedophilic disorder...

BACKGROUND: Clitoromegaly is often a sign of an underlying disorder of sexual development. Isolated clitoromegaly may occur as a result of benign or malignant neoplasm. CASE: A 10-year-old female presented with clitoral swelling and discomfort and was noted to have a 5X2X2 centimeter, tender, cystic mass in the left periclitoral area. Ultrasound confirmed the primarily cystic nature of the lesion. At surgery the mass was carefully excised not damaging the clitoral neurovascular bundle...

OBJECTIVE: Eating disorders are understudied among female U.S. military veterans, who may be at increased risk due to their high rates of trauma exposure and trauma-related sequelae. The current study sought to examine whether different types of trauma in childhood and adulthood confer differential risk for eating disorder symptoms (EDSs) in this population. METHOD: We analyzed survey data from a sample of female Veterans Health Administration patients (N = 186) to examine the association between 5 trauma types (i...

BACKGROUND: Major depressive disorder (MDD) is a severe mental illness that affects more than 350 million people worldwide. However, the molecular mechanisms of depression are currently unclear. Studies suggest that Drosophila and humans have similar depression-like symptoms under pressure. In this research, we choose Drosophila melanogaster as the animal model to explore the molecular mechanisms that trigger depression. RESULTS: We found that feeding D. melanogaster with the medium containing Levodopa or Chlorpromazine could induce depression-like phenotypes in both behavioral and biochemical biomarkers, including significantly decreased food intake, mating frequency, serotonin (5-HT) concentration, and increased malondialdehyde (MDA) concentration as well as reduced activity of superoxide dismutase (SOD)...

46,XX disorders of sexual development (DSDs) occur rarely and result from disruptions of the genetic pathways underlying gonadal development and differentiation. We present a case of a young phenotypic male with 46,XX SRY-negative ovotesticular DSD resulting from a duplication upstream of SOX9 presenting with a painful testicular mass resulting from ovulation into an ovotestis. We present a literature review of ovulation in phenotypic men and discuss the role of SRY and SOX9 in testicular development, including the role of SOX9 upstream enhancer region duplication in female-to-male sex reversal...

Amir Weintraub, Talia Eldar-Geva
Anti-Mullerian hormone (AMH), secreted by immature testicular Sertoli-cells, triggers the regression of male fetal Mullerian ducts. During puberty, AMH is downregulated by intratesticular testosterone. In females, AMH is secreted from granulosa cells of immature ovarian follicles from late prenatal life until menopause; serum concentration is 5-20 times lower in females than in males through lifetime. In boys, AMH determination is useful in the clinical setting as a marker of Sertoli cell function. Serum AMH is low in infants with hypogonadotrophic hypogonadism (and increases with FSH treatment), in patients with primary hypogonadism from early postnatal life and in Klinefelter syndrome from midpuberty...

BACKGROUND: Infections of the genital tract are considered common causes of male fertility disorders, with a prevalence of 6-10%. Most of the affected men are asymptomatic. The diagnostic evaluation is based mainly on laboratory testing. Inconsistent diagnostic criteria have been applied to date, and this may explain the controversial debate about the role of infection and inflammation in the genital tract as a cause of infertility. The risk of an irreversible fertility disorder should not be underestimated...

BACKGROUND: Ambiguous genitalia is an uncommon situation that happens between 1 and 2 per every 1000 live births and falls under the umbrella diagnosis of disorders of sexual development. CASE: In this article, we report a case of male pseudohermaphroditism with ambiguous genitalia. The proband was a 12 yr old girl without any uterus or ovarian tissues. Karyotype of the case is 46, XY. Genes involved in sexual differentiation such as AR, SRD5A2, LH, LHR, FSH, 17 B HSD and SRY genes were sequenced in both directions...

BACKGROUND: Although child maltreatment is a well documented risk factor for suicidal behavior, little is known about whether the timing of child maltreatment differentially associates with risk of suicidal ideation, suicide plans, or suicide attempts. The goal of this study was to examine whether a first exposure to physical or sexual abuse during specific developmental periods significantly elevated risk for suicidal behavior in adolescents. METHODS: Data came from the National Comorbidity Survey Adolescent Supplement, a population-based sample of US adolescents aged 13-18 years old (n = 9,272)...

Research into sexual dysfunction and its explanations within a cognitive behavioral framework in patients with posttraumatic stress is sparse. In this report, we present the case of a 42-year-old male with severe posttraumatic stress symptoms who displayed apparent exhibitionistic behavior, hypersexual behavior in the form of excessive masturbation, and erectile dysfunction. Differential diagnostics showed that the presented exhibitionistic behavior could be more accurately classified as non-paraphilic disinhibited exposing behavior...
