Abstract
Key clinical message 5-Alpha reductase deficiency is an important cause of 46, XY disorder of sex development. Timely diagnosis and proper management by a multidisciplinary team can lead to a favorable outcome. Sex assignment should be deferred until puberty because spontaneous virilization occurs and the patient can engage in the decision-making process. Abstract 5-Alpha reductase deficiency is a genetic disorder causing 46, XY disorder of sex development (DSD). Typical clinical feature is a male with ambiguous genitalia or undervirilization at birth. Here we report three cases of this disorder within a family.

Abstract
Dynamic tests are often considered as the backbone of endocrinology. These tests involve the use of an exogenous agent to manipulate the body's hormonal milieu for the diagnosis and characterization of an endocrine disorder. They are especially helpful in the evaluation of certain endocrine conditions, such as disorders of growth and pubertal maturation and disorders of sex development. A great deal of heterogeneity exists across clinicians with regard to the usage, methodology, and interpretation of these tests. This review outlines various dynamic tests used to evaluate adrenal and gonadal function in pediatric and adult endocrinology, along with their clinical application and interpretation.

Abstract
The present study explored the relations between self-reported aspects of gender identity and sexual orientation in an online sample of 4756 cisgender English-speaking participants (1129 men) using the Multi-Gender Identity Questionnaire and a sexual orientation questionnaire. Participants also labeled their sexual orientation. We found a wide range of gender experiences in the sample, with 38% of the participants feeling also as the "other" gender, 39% wishing they were the "other" gender, and 35% wishing they had the body of the "other" sex. Variability in these measures was very weakly related to sexual orientation, and these relations were gender-specific, being mostly U shaped (or inverted-U shaped) in men and mostly linear asymptotic in women. Thus, in women, feeling-as-a-woman was highest in the exclusively heterosexual group, somewhat lower in the mostly heterosexual group, and lowest in the bisexual, mostly homosexual, and exclusively homosexual groups, which did not differ, and the reverse was true for feeling-as-a-man (i.e., lowest in the exclusively heterosexual group and highest in the bisexual, mostly homosexual, and exclusively homosexual groups). In men, feeling-as-a-man was highest at both ends of the sexual orientation continuum and lowest at its center, and the reverse was true for feeling-as-a-woman. Similar relations were evident also for the other aspects of gender identity. This study adds to a growing body of literature that questions dichotomous conventions within the science of gender and sexuality. Moreover, our results undermine the tight link assumed to exist between sexual and gender identities, and instead posit them as weakly correlated constructs.

Abstract
Gynecologic Oncologists are sometimes consulted to care for patients who present with diverse gender identities or sexual orientations. Clinicians can create more helpful relationships with their patients if they understand the etiologies of these diverse expressions of sexual humanity. Multidisciplinary evidence reveals that a sexually dimorphic spectrum of somatic and neurologic anatomy, traits and abilities, including sexual orientation and gender identity, are conferred together during the first half of pregnancy due to genetics, epigenetics and the diversity of timing and function of sex chromosomes, sex-determining protein secretion, gonadal hormone secretion, receptor levels, adrenal function, maternally ingested dietary hormones, fetal health, and many other factors. Multiple layers of evidence confirm that sexual orientation and gender identity are as biological, innate and immutable as the other traits conferred during that critical time in gestation. Negative social responses to diverse orientations or gender identities have caused marginalization of these individuals with resultant alienation from medical care, reduced self-care and reduced access to medical care. The increased risks for many diseases, including gynecologic cancers are reviewed. Gynecologic Oncologists can potentially create more effective healthcare relationships with their patients if they have this information.

Dutasteride-mediated morphological changes in the genitourinary tract associated with altered expression patterns of the androgen and estrogen receptors in male rats. Andrology 2016; 5:347-353.

Abstract
We evaluated the effects of dutasteride on the genitourinary tract using fifteen 8-week-old male Sprague-Dawley rats. Animals were divided into three groups comprising five animals each and treated as follows. Group A was a control group, members of Group B received oral administration of dutasteride 0.1 mg/kg/day from the age of 8 to 16 weeks, and members of Group C were castrated at the age of 8 weeks. All rats were killed at the age of 16 weeks for the sample collection of blood, bladder, prostate, seminal vesicles, and penis. Then, we evaluated the pathological examination for evaluating the tissue fibrosis and hormonal receptor expression. The results showed that the mean size of the prostate and seminal vesicles was smaller in Group B and Group C than in Group A. Serum and tissue concentrations of both testosterone and dihydrotestosterone were remarkably reduced in serum and all tissues in Group C compared with Group A. On the other hand, in Group B, only dihydrotestosterone was reduced in serum and penis. Histopathological examination revealed that Group C showed statistically significant histological changes, such as an increase in fibrotic tissue in the bladder, prostate, and penis. Similarly, Group B showed fibrotic changes in the prostate and penis compared with the Group A. Immunofluorescent staining revealed that the androgen receptor was more strongly expressed than the estrogen receptor beta in Group A. On the other hand, in Group C, weak expression of the androgen receptor and strong expression of the estrogen receptor beta was noted. In Group B, these changes were noted in the prostate and penis. These findings suggest that dutasteride cause morphological changes not only in prostate but also in penis. These changes are associated with altered expression patterns of androgen receptor and estrogen receptor.

Abstract
Master N had genital malformation at birth and had bilateral gonads in the labial fold. He was reared as a boy and corrective surgery was done at the age of 4 years and was reassessed at the age of 14 years. His testosterone/dihydrotestosterone (DHT) was 11.8 (reference range <=10). Molecular analysis of SRD5A2 gene indicated the presence of a novel heterozygous missense mutation of p.A52T in exon 1, which was also detected in mother. The father, sister and maternal grandfather were found to have normal SRD5A2 gene sequence. We also detected an intronic (1-2) homozygous T>C transition in patient, whereas both parents were found to have the same transition in heterozygous form. Although 5α-steroid reductase 2 deficiency is an autosomal-recessive disorder, in this case, it appears that there may be a dominant inheritance because only one identified mutation was present which was passed from mother to son.

Abstract
INTRODUCTION Both biological and psychosocial factors influence psychosexual development. High levels of pre- and postnatal androgens lead to more male-typical behavior. So far, the influence of androgens on gender identity and sexual orientation is unclear. Disorders of sex development (DSDs) are heterogeneous genetic conditions with different levels of prenatal androgens resulting in variations of genital development. Through DSD, the role of the different factors, especially androgen exposure, on psychosexual development can be evaluated. AIM The purpose of the study was to assess psychosexual development in adolescents and adults with different forms of DSD. METHODS For the examination of psychosexual development of 66 adolescents and 110 adults with DSD, the authors used the Utrecht Gender Dysphoria Scale for adolescents, the Questionnaire of Gender Identity for adults, and a condition-specific DSD study questionnaire. Individuals were analyzed in four subgroups reflecting the karyotype, absence/presence of androgen effects, and gender of rearing. MAIN OUTCOME MEASURES Main outcome measures used were gender identity, friendships, love and sexual relationships, and sexual orientation in adolescents and adults with DSD. RESULTS Individuals with DSD did not show increased gender dysphoria. However, partnership and sexuality were identified to be difficult areas of life. Both adolescents and adults with DSD reported fewer experiences regarding love or sexual relationships compared with unaffected individuals. Especially men with DSD and undervirilization and women with DSD and androgen effects less often had a love relationship. Adult women with DSD and androgen effects more frequently engaged in love and sexual relationships with individuals of the same gender compared with women without DSD. CONCLUSION Individuals with DSD experience atypical hormonal influences (higher levels of androgens in girls/women and lower levels in androgens in boys/men); however, they did not show increased gender dysphoria in this study. However, partnership and sexual relationships are difficult areas of life for adolescents and adults with DSD. We recommend that individuals with DSD should get support from a multiprofessional team with competency in assessing and counseling issues regarding relationships and sexuality. Contact to other individuals with DSD can be helpful for nonprofessional support and exchange of experiences.

Abstract
The aim of this study was to search for clinical and laboratorial data in 46,XY patients with ambiguous genitalia (AG) and normal testosterone (T) synthesis that could help to distinguish partial androgen insensitivity syndrome (PAIS) from 5α-reductase type 2 deficiency (5α-RD2) and from cases without molecular defects in the AR and SRD5A2 genes. Fifty-eight patients (51 families) were included. Age at first evaluation, weight and height at birth, consanguinity, familial recurrence, severity of AG, penile length, LH, FSH, T, dihydrotestosterone (DHT), Δ4-androstenedione (Δ4), and T/DHT and T/Δ4 ratios were evaluated. The AR and SRD5A2 genes were sequenced in all cases. There were 9 cases (7 families) of 5α-RD2, 10 cases (5 families) of PAIS, and 39 patients had normal molecular analysis of SRD5A2 and AR genes. Age at first evaluation, birth weight and height, and T/DHT ratio were lower in the undetermined group, while penile length was higher in this group. Consanguinity was more frequent and severity of AG was higher in 5α-RD2 patients. Familial recurrence was more frequent in PAIS patients. Birth weight and height, consanguinity, familial recurrence, severity of AG, penile length, and T/DHT ratio may help the investigation of 46,XY patients with AG and normal T synthesis.

Abstract
Psychosexual development is influenced by biological and psychosocial factors. Human beings show a great variability in psychosexual development both between and within gender-groups. However, there are relatively stable gender-related behaviors and self-perceptions, in which males and females differ distinctly. There is strong evidence that high concentrations of androgens lead to more male-typical behavior and that this also influences gender identity. Disorders of sex development (DSD) provide the opportunity to analyze the role of different factors on psychosexual development. We examined 166 children age 4 to 12 with DSD using instruments concerning gender role behavior, gender identity, and friendship. Results underline the hypothesis, that androgens play a decisive role in the masculinization of gender role behavior in children. There are also some relations between the experience of gender change and psychosexual outcomes which have to be discussed. Nevertheless, results indicated a high congruence between the children's gender identity and gender of rearing.
