Abstract
INTRODUCTION Although it was common in the 1970s-1990s to assign female gender of rearing to 46,XY infants with limited virilization of varying etiologies, including those with partial androgen insensitivity syndrome (PAIS), long-term data on outcomes for these individuals are sparse. Therefore, our goal was to use the power of an international registry to evaluate clinical features, surgical management, and pubertal data in patients with a molecularly confirmed diagnosis of PAIS who were born before 2008 and were raised as girls. METHODS The current study interrogated the International Disorders of Sex Development Registry for available data on management and pubertal outcomes in individuals with genetically confirmed PAIS who were raised as girls. RESULTS Among the 11 individuals who fulfilled the key criteria for inclusion, the external masculinization score (EMS) at presentation ranged from 2 to 6 (median 5); 7 girls underwent gonadectomy before the age of 9 years, whereas 4 underwent gonadectomy in the teenage years (≥ age 13). Clitoral enlargement at puberty was reported for 3 girls (27%) who presented initially at the time of puberty with intact gonads. In the 9 individuals (82%) for whom gonadal pathology data were provided, there was no evidence of germ cell tumor at median age of 8.1 years. All girls received estrogen replacement, and 8/11 had attained Tanner stage 4-5 breast development at the last assessment. CONCLUSION In general, although it appears that female assignment in PAIS is becoming uncommon, our data provide no evidence to support the practice of prophylactic prepubertal gonadectomy with respect to the risk of a germ cell tumor.

Abstract
This study describes the clinical, biochemical, and molecular characteristics of Indian children with 46,XY DSD and suspected androgen insensitivity syndrome (AIS). Fifty children (median age 3.0 years, range 0-16.5 years) with 46,XY DSD and a suspected diagnosis of AIS were enrolled. Sanger sequencing was performed to identify pathogenic variants in the androgen receptor (AR) gene and to study genotype-phenotype correlations. All 5 (100%) patients with CAIS and 14/45 (31%) patients with PAIS had pathogenic/likely pathogenic variants in the AR gene (overall, 14 different variants in 19 patients; 38.8%). There was no significant difference in clinical (cryptorchidism, hypospadias, or external masculinizing score) or biochemical parameters (gonadotropins and testosterone) between patients with or without pathogenic variants. However, patients with AIS were more likely to have a positive family history, be assigned female gender at birth, and present with gynaecomastia at puberty. Three novel pathogenic/likely pathogenic variants, including one splice donor site variant c.2318+1G>A, one frameshift variant p.H790Lfs*40, and one missense variant p.G821E, were identified in 3 patients with CAIS. The missense variant p.G821E was predicted as deleterious, damaging, disease-causing, and likely functionally inactive by in silico analysis and protein modelling study. Two previously not reported pathogenic/likely pathogenic variants, including p.R386H and p.G396R, were identified in patients with PAIS. This study contributes in expanding the spectrum of pathogenic variants in the AR gene in patients with AIS. Only 31% patients with a provisional diagnosis of PAIS had pathogenic variants in the AR gene, suggesting other possible mechanisms or candidate genes may be responsible for such a phenotypic presentation.

Abstract
Introduction and importance The partial androgen insensitivity syndrome (PAIS) is a rare genetic disorder, which needs to be diagnosed early and provided suitable treatment. One-stage sex reassignment surgery can be considered as one of the treatment options for PAIS patients. Case presentation A 44-year-old patient with PAIS was admitted to our hospital. After getting a consultation, the patient decided to choose the one-stage sex reassignment surgery to be reassigned to be a female. The surgery consisted of breast augmentation and genital surgery. After 8 months of follow-up, the patient's breast had a desired shape and volume. The clitoris was in normal size with normal sensation, and the neovagina was 8 cm in depth with a smooth mucosal surface. We also observed that the minor labia were symmetric. The patient reported achieving orgasms with sex toys. Clinical discussion The one-stage sex reassignment surgery for the PAIS patient is safe and reduces treatment time for patients. It could also bring many benefits to the patients, such as reducing the incision, preventing gonadoblastoma and giving a sense of the patient's female gender which helps the patient feel confident and improve her quality of life. Thus, the one-stage surgery should be indicated for the patient at middle-aged who shouldn't be delayed anymore to have normal female breast and external genitalia. Conclusion The one-stage sex reassignment surgery was performed safely and successfully on the delayed presentation of the PAIS patient. This could be an effective and appropriate approach to treat late-diagnosed PAIS patients. One-stage sex reassignment surgery for a patient with partial androgen insensitivity syndrome A 44-year-old patient at the delayed presentation of the disorder We observed good treatment outcomes with a 8-moth follow-up

Abstract
Partial androgen insensitivity syndrome (PAIS) is a form of disorders of sexual development. Besides the issues of gender assignment, the fate of gonads in these patients poses a challenging problem. Debate still remains on the need and/or timing of gonadectomy in either complete or partial androgen insensitivity syndromes. In this case report, we present a 68-year-old patient who was raised as a woman, stayed married for 45 years and admitted to our endocrinology department with complaint of male type hair distribution after initial examination following move to a nursing home. Physical examination revealed no breast development, a phallus of 6 cm, labia majoras that include testes and a blind ending vagina. Chromosomal analysis confirmed 46,XY with intact SRY and AZF regions. Pelvic ultrasonography and magnetic resonance imaging results indicated testicular tissue in labia majoras in addition to a rudimentary prostate. Gonadectomy was not offered to the patient due to lacking evidence of benefit in this age group and considering possible hormonal side effects. Our patient might be the oldest patient to be diagnosed with PAIS. Treatment and follow-up protocols for adults with PAIS are not standardized and therefore these patients should be individually evaluated and treated. Risks and benefits of surgery should be kept in mind when suggesting gonadectomy.

Abstract
BACKGROUND Complete and partial androgen insensitivity syndrome (CAIS, PAIS) are associated with an increased risk of gonadal germ cell cancer (GGCC). Recent guidelines recommend gonadectomy in women with CAIS in late adolescence. Nevertheless, many adult women prefer to retain their gonads. AIMS This study aims to explore attitudes towards gonadectomy in AIS in centres around the world, estimate the proportion of adults with retained gonads and/or who developed GGCC, and explore reasons for declining gonadectomy. METHODS A survey was performed among health care professionals who use the International DSD Registry (I-DSD). RESULTS Data were provided from 22 centres in 16 countries on 166 women (CAIS) and 26 men (PAIS). In CAIS, gonadectomy was recommended in early adulthood in 67% of centres; 19/166 (11.4%) women refused gonadectomy. Among 142 women who had gonadectomy, evidence of germ cell neoplasm in situ (GCNIS), the precursor of GGCC, was reported in 2 (1.4%) out of 8 from whom pathology results were formally provided. Nine out of 26 men with PAIS (34.6%) had retained gonads; 11% of centres recommended routine gonadectomy in PAIS. CONCLUSION Although development of GGCC seems rare, gonadectomy after puberty is broadly recommended in CAIS; in PAIS this is more variable. Overall, our data reflect the need for evidence-based guidelines regarding prophylactic gonadectomy in AIS.
