Abstract
Congenital adrenal hyperplasia is a group of autosomal recessive disorders leading to multiple complex hormonal imbalances caused by various enzyme deficiencies in the adrenal steroidogenic pathway. The most common type of congenital adrenal hyperplasia is due to steroid 21-hydroxylase (21-OHase, henceforth 21OH) deficiency. The rare, classic (severe) form caused by 21OH deficiency is characterised by life-threatening adrenal crises and is the most common cause of atypical genitalia in neonates with 46,XX karyotype. After the introduction of life-saving hormone replacement therapy in the 1950s and neonatal screening programmes in many countries, nowadays neonatal survival rates in patients with congenital adrenal hyperplasia are high. However, disease-related mortality is increased and therapeutic management remains challenging, with multiple long-term complications related to treatment and disease affecting growth and development, metabolic and cardiovascular health, and fertility. Non-classic (mild) forms of congenital adrenal hyperplasia caused by 21OH deficiency are more common than the classic ones; they are detected clinically and primarily identified in female patients with hirsutism or impaired fertility. Novel treatment approaches are emerging with the aim of mimicking physiological circadian cortisol rhythm or to reduce adrenal hyperandrogenism independent of the suppressive effect of glucocorticoids.

De Clercq E, Starke G, Rost M. "Waking up" the sleeping metaphor of normality in connection to intersex or DSD: a scoping review of medical literature. HISTORY AND PHILOSOPHY OF THE LIFE SCIENCES 2022; 44:50.

Abstract
The aim of the study is to encourage a critical debate on the use of normality in the medical literature on DSD or intersex. For this purpose, a scoping review was conducted to identify and map the various ways in which "normal" is used in the medical literature on DSD between 2016 and 2020. We identified 75 studies, many of which were case studies highlighting rare cases of DSD, others, mainly retrospective observational studies, focused on improving diagnosis or treatment. The most common use of the adjective normal was in association with phenotypic sex. Overall, appearance was the most commonly cited criteria to evaluate the normality of sex organs. More than 1/3 of the studies included also medical photographs of sex organs. This persistent use of normality in reference to phenotypic sex is worrisome given the long-term medicalization of intersex bodies in the name of a "normal" appearance or leading a "normal" life. Healthcare professionals should be more careful about the ethical implications of using photographs in publications given that many intersex persons describe their experience with medical photography as dehumanizing.

45 years' experience with early childhood anatomical technique of feminising genitoplasty for 46 XX Congenital Adrenal Hyperplasia -observations of vaginal introital anatomy and its relationship to the perineal body. J Pediatr Urol 2022; 18:611.e1-611.e8. [PMID: 35970739 DOI: 10.1016/j.jpurol.2022.07.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2021] [Revised: 05/26/2022] [Accepted: 07/10/2022] [Indexed: 12/14/2022]
Abstract
In Manchester, feminising genitoplasty is offered to children with 46XX Congenital Adrenal Hyperplasia (CAH) when there is a single perineal opening and/or enlarged clitoris. Our aims are to describe the anatomical reconstructive technique and present long-term outcomes. Our hypothesis is that 'the common channel (CC) length and distance to the vagina from perineal skin is mostly due to virilisation and hypertrophy of perineal tissue over the almost normally positioned vaginal introitus (V-I) in relation to the perineal body (PB)'. METHOD AND RESULTS: This is a retrospective notes review of all consecutive 46XX CAH operations from 1976 to December 2021. 99 patients, who had feminising genitoplasty and being followed-up, were included. 15 patients who were lost to follow up were excluded. Median age at surgery was 15 months. In 91, midline division of the labia majora, spongiosum, bulbo-spongiosus muscle (BSM) and CC down to PB was performed. This was sufficient to expose the V-I at the same level or within 5 mm depth of PB in 88. In 78 V-I was adequate taking 10/12fr dilator (Type 1). In 10, CC resembled a male urethra and V-I was narrow (Type 2), requiring widening by 5-10 mm incision at 6 o'clock position. Dartos of labia majora was attached to BSM to reduce the distance to V-I from perineal skin and the gap was lined with inner foreskin to create a vestibule. Out of 70 who were post-pubertal, 75% (53/70) had adequate calibre vaginal openings. 5 had introitoplasty and 2 had dilatation under anaesthesia. 10 needed self dilators only. 29 patients, of one of the three surgeons, had measurements of clitoris, CC, urethra and vagina. A hymen was found in 86% (25/29). There was significant strong, inverse correlation between the CC length and the urethral length (r = -0.708, p < 0.001, n = 27) but not between CC and vaginal lengths. After adjusting for age, the urethral length of Type 2 patients was 3.825 mm shorter than those of Type 1 (p = 0.017). CONCLUSION: Our data show that 'high' confluence is mostly due to virilisation of genitalia; and the anatomical technique of reversing the fusion of the urethral folds, spongiosum and bulbo-spongiosus muscle could be performed with all degrees of virilisation with success in early childhood with no need of local flaps or mobilisation of the urethro-vaginal complex. About 10% require surgery to treat narrowing of vaginal opening post puberty.

Techniques of Primary Vaginoplasty in Young Adults with Differences of Sex Development and Female Identification. J Clin Med 2022; 11:jcm11133688. [PMID: 35806974 PMCID: PMC9267529 DOI: 10.3390/jcm11133688] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Revised: 06/20/2022] [Accepted: 06/22/2022] [Indexed: 02/01/2023] Open
Abstract
Background: The ideal timing of genital surgery in differences/disorders of sex development (DSD) is controversial and differs according to the underlying type of DSD. Increasing numbers of persisting sinus as a result of delayed feminizing genitoplasty in DSD patients require interdisciplinary collaboration of pediatric surgeons/urologists and gynecologists. This study focusses on surgical techniques other than bowel vaginoplasties and results of gender assigning surgery in young adolescents. Methods: Data of adolescent and adult patients treated between 2015 and 2022 were analyzed retrospectively: underlying type of malformation, techniques of vaginoplasty, vaginal length and caliber, possibility of sexual intercourse, and temporary vaginal dilatation. Results: A total of 9 patients received a primary vaginoplasty at a median age of 16.75 years (range 10.3–29.25). The underlying anatomical conditions were persistent urogenital sinus (UGS) in 8 patients (3 patients with CAH, 2 patients with XY-DSD, 1 patient with cloacal malformation and missed UGS, 2 patients with UGS only). One patient had a MURCS association. Surgical techniques were total urogenital mobilization and perineal flap vaginoplasty in 4 patients, modified McIndoe vaginoplasty in 4 patients, and a laparoscopic vaginal pull-through in 1 patient. In a median follow-up of 45 months (2–84), all but 1 patient presented with physiological vaginal length and width. Conclusions: If possible, modern treatment concepts delay gender assigning surgery until the participation of the patient in the decision-making process is possible. Optimal treatment concepts are given by transfer of surgical techniques from pediatric urology/surgery by multidisciplinary teams. Techniques other than bowel vaginoplasties are favorable.

Abstract
Disorders/differences of sex development (DSD) are congenital conditions in which there is atypical chromosomal, gonadal and/or phenotypic sex. While there remains controversy around the traditionally binary concept of sex, most patients with DSD are reared either male or female depending on their genetic sex, gonadal sex, genital phenotype and status of their internal genital tract. This study uses prospective data from 12 institutions across the United States that specialize in DSD care. We focused on patients raised female. Eligible patients had moderate to severe genital atypia (defined as Prader score >2), were ≤2 years of age at entry, and had no prior genitoplasty. The aim of this study is to describe early post operative complications for young patients undergoing modern approaches to feminizing genitoplasty. Of the 91 participants in the cohort, 57 (62%) were reared female. The majority had congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (n = 52), 1 had ovo-testicular syndrome, 2 had mixed gonadal dysgenesis and 2 had partial androgen insensitivity syndrome (PAIS). Of the 50 participants who received early genitoplasty, 43 (86%) had follow-up at 6-12 months post-surgery. Thirty-two participants (64%) received a clitoroplasty, 31 (62%) partial urogenital mobilization and 4 (8%) total urogenital sinus mobilization. Eighteen percent (9/50) experienced post-surgical complications with 7 (14%) being rated as Clavien-Dindo grade III. Both parents and surgeons reported improved satisfaction with genital appearance of participants following surgery compared to baseline. This information on post-operative complications associated with contemporary approaches to feminizing genitoplasty performed in young children will help guide families when making decisions about whether or not to proceed with surgery for female patients with moderate to severe genital atypia.

Abstract
The care of individuals with disorders/differences of sex development aims to enable affected individuals and their families to have the best quality of life, particularly those born with severe genital ambiguity. Two of the biggest concerns for parents and health professionals are: (1) making a gender assignment and (2) the decisions of whether or not surgery is indicated, and if so, when is best for the patient and parents. These decisions, which can be overwhelming to families, are almost always made in the face of uncertainties. Such decisions must involve the parents, include multidisciplinary contributions, have an underlying principle of full disclosure, and respect familial, philosophical, and cultural values. Assignment as male or female is made with the realization that gender identity cannot be predicted with certainty. Because of the variability among those with the same diagnosis and complexity of phenotype-genotype correlation, the use of algorithms is inappropriate. The goal of this article is to emphasize the need for individualized care to make the best possible decisions for each patient's unique situation.

Abstract
Appropriate management of disorders of sex development (DSD) has been a matter of discussion since the first guidelines were published in the 1950s. In the last decade, with the advent of the 2006 consensus, the classical methods, especially regarding timing of surgery and sex of rearing, are being questioned. In our culture, parents of DSD newborns usually want their children to undergo genital surgery as soon as possible after sexual assignment, as surgery helps them to confirm the assigned sex. Developmental psychology theories back this hypothesis. They state that anatomic differences between sexes initiate the very important process of identification with the parent of the same sex. Sex-related endocrinological issues also demand early care. For example, using dihydrotestosterone cream to increase penile length or growth hormone treatment to improve final height require intervention at young ages to obtain better results. Although the timing of surgery remains controversial, recent evidence suggests that male reconstruction should be performed between 6 and 18 months of age. Feminizing surgery is still somewhat controversial. Most guidelines agree that severe virilization requires surgical intervention, while no consensus exists regarding mild cases. Our perspective is that precocious binary sex assignment and early surgery is a better management method. There is no strong evidence for delays and the consequences can be catastrophic in adulthood.

Abstract
The human penis and clitoris develop from the ambisexual genital tubercle. To compare and contrast the development of human penis and clitoris, we used macroscopic photography, optical projection tomography, light sheet microscopy, scanning electron microscopy, histology and immunohistochemistry. The human genital tubercle differentiates into a penis under the influence of androgens forming a tubular urethra that develops by canalization of the urethral plate to form a wide diamond-shaped urethral groove (opening zipper) whose edges (urethral folds) fuse in the midline (closing zipper). In contrast, in females, without the influence of androgens, the vestibular plate (homologue of the urethral plate) undergoes canalization to form a wide vestibular groove whose edges (vestibular folds) remain unfused, ultimately forming the labia minora defining the vaginal vestibule. The neurovascular anatomy is similar in both the developing human penis and clitoris and is the key to successful surgical reconstructions.

Abstract
PURPOSE OF REVIEW Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a relatively common inherited disorder of cortisol biosynthesis that can be fatal if untreated. RECENT FINDINGS The basic biochemistry and genetics of CAH have been known for decades but continue to be refined by the discoveries of an alternative 'backdoor' metabolic pathway for adrenal androgen synthesis and the secretion of 11-hydroxy and 11-keto analogs of known androgens, by the elucidation of hundreds of new mutations, and by the application of high-throughput sequencing techniques to noninvasive prenatal diagnosis. Although hydrocortisone is a mainstay of treatment, overtreatment may have adverse effects on growth, risk of obesity, and cardiovascular disease; conversely, undertreatment may increase risk of testicular adrenal rest tumors in affected men. SUMMARY Refinements to screening techniques may improve the positive predictive value of newborn screening programs. Alternative dosing forms of hydrocortisone and additional therapeutic modalities are under study. Although surgical treatment of virilized female genitalia is widely accepted by families and patients, it is not without complications or controversy, and some families choose to defer it.
