During the intrauterine period the fetal brain develops in the male direction through a direct action of testosterone on the developing nerve cells, or in the female direction through the absence of this hormone surge. In this way, our gender identity (the conviction of belonging to the male or female gender) and sexual orientation are programmed into our brain structures when we are still in t...
Background & Aim: Obesity Mood disorders are among the most prevalent psychiatric diseases which occur due to ineffective coping strategies; thus, investigation of its related factors is of importance. This study was conducted to determine the relationship of Self-Differentiation with Stress-Coping Strategies and Suicide in Patients with Mood Disorders. Methods: In this correlational-descrip...
Male sexual differentiation of the brain and behavior are thought, on the basis of experiments in rodents, to be caused by androgens, following conversion to estrogens. However, observations in human subjects with genetic and other disorders show that direct effects of testosterone on the developing fetal brain are of major importance for the development of male gender identity and male heteros...
Sexual ambiguity commonly known as intersexuality, is a condition of imperfect sexual differentiation between male and female. The present study was aimed at analyzing the chromosomal abnormalities of intersex subjects in Coimbatore city, India Of the 30 intersex cases studied, 10 of them were genetically male (46,XY) but phenotypically females, 8 of them were genetically female (46,XX) with ma...
Ovotesticular DSD is not an uncommon disorder. The presence of Y chromosome confers a high risk of neoplastic transformation in dysgenetic gonads. The neoplastic development in these patients is associated with the presence of Y chromosome and intra abdominal location of the abnormal gonad. We report histogenetic details of a rare occurrence of bilateral gonadoblastomas and left sided dysgermin...
Women with schizophrenia express affective disturbances disproportionately more than men. Brain regions implicated in the affective arousal circuitry also regulate the hypothalamic-pituitary-adrenal and -gonadal systems, which are dysfunctional in schizophrenia. This review will argue that understanding the etiology of affective arousal deficits in schizophrenia is intimately connected with cha...
The 46 XX, testicular sex differentiation disorder, or XX male syndrome, is a rare condition detected by cytogenetics, in which testicular development occurs in the absence of the Y chromosome. It occurs in 1:20,000 to 25,000 male newborns and represents 2% of cases of male infertility. About 90% of individuals present with normal phenotype at birth and are generally diagnosed after puberty for...
Both sexual differentiation, which is a matter of individual development, and sexual dissimilation, which is a matter of individual differences, result from developmental processes that are open to input from the early maternal environment. There are reliable features in both the dam and the young that ensure that males receive more perineal stimulation from maternal licking than is necessary f...
