Sexual function and fertility in adult females and males with congenital adrenal hyperplasia

Psychological adjustment, quality of life, and self-perceptions of reproductive health in males with congenital adrenal hyperplasia: a systematic review

PURPOSE

Congenital adrenal hyperplasia (CAH) has been shown to potentially affect psychological adjustment. However, most research has focused on females, and knowledge about psychological challenges in males remains sparse. The aim of this systematic review was therefore to assess these in males with CAH.

METHODS

We systematically searched the OVID Medline, PsycINFO, CINAHL, and Web of Science databases, for articles published up to April 20, 2018, investigating psychological adjustment in males with CAH.

RESULTS

Eleven studies were included in the review. Three main health domains were identified: psychological and psychiatric health, quality of life (QoL), and self-perceptions of reproductive health. Some studies covered more than one health domain. Seven studies explored psychological adjustment and/or the presence of psychiatric symptoms or disorders. Results indicated that males with CAH had more problems related to internalizing behaviors (negative behaviors directed toward the self) and more negative emotionality compared to reference groups. Six studies examined QoL, five of them reporting reduced QoL compared to reference groups. Three studies explored the impact of fertility and sexual health issues on psychological health with varying results from impaired to normal sexual well-being.

CONCLUSIONS

CAH seems to have an impact on males' psychological health. However, the number of identified studies was limited, included few participants, and revealed divergent findings, demonstrating the need for larger studies and highlighting a number of methodological challenges that should be addressed by future research.

Sexual dysfunction and male infertility

Infertility affects up to 12% of all men, and sexual dysfunction occurs frequently in men of reproductive age, causing infertility in some instances. In infertile men, hypoactive sexual desire and lack of sexual satisfaction are the most prevalent types of sexual dysfunction, ranging from 8.9% to 68.7%. Erectile dysfunction and/or premature ejaculation, evaluated with validated tools, have a prevalence of one in six infertile men, and orgasmic dysfunction has a prevalence of one in ten infertile men. In addition, infertile men can experience a heavy psychological burden. Infertility and its associated psychological concerns can underlie sexual dysfunction. Furthermore, general health perturbations can lead to male infertility and/or sexual dysfunction. Erectile dysfunction and male infertility are considered proxies for general health, the former underlying cardiovascular disorders and the latter cancerous and noncancerous conditions. The concept that erectile dysfunction in infertile men might be an early marker of poor general health is emerging. Finally, medications used for general health problems can cause sperm abnormalities and sexual dysfunction. The treatment of some causes of male infertility might improve semen quality and reverse infertility-related sexual dysfunction. In infertile men, an investigation of sexual, general, and psychological health status is advisable to improve reproductive problems and general health.

One hundred years of congenital adrenal hyperplasia in Sweden: a retrospective, population-based cohort study

BACKGROUND

Congenital adrenal hyperplasia due to 21-hydroxylase deficiency results in cortisol and aldosterone deficiency and is, in its most severe form, lethal. We aimed to assess the effect of historical medical improvements in the care of patients with this disorder over time and to assess the effects of neonatal screening in Sweden.

METHODS

For this retrospective, population-based cohort study, we collected data for all known patients with congenital adrenal hyperplasia in Sweden between 1910 and 2011 [corrected]. Data sources included the registry at the Swedish national screening laboratory, patients identified via the Swedish neonatal screening programme, late-diagnosed patients reported to the laboratory, and patients who underwent genetic diagnostics or became known to us through clinical contacts. All known patients were included in a population-based cohort study of the distribution of clinical severity, genotype, sex, and the effect of nationwide neonatal screening.

FINDINGS

We identified 606 patients with the disorder, born between 1915 and 2011. The CYP21A2 genotype (conferring deficiency of 21-hydroxylase) was known in 490 patients (81%). The female-to-male ratio was 1·25 in the whole cohort, but close to 1 in patients detected by the screening. We noted a sharp increase in the number of patients diagnosed in the 1960s and 1970s, and after the introduction of neonatal screening in 1986 the proportion of patients with the salt-wasting form of congenital adrenal hyperplasia increased in both sexes, from 114 (47%) of 242 individuals between 1950 and 1985 to 165 (57%) of 292 individuals between 1986 and 2011 (p=0·038). On average, five to ten children were missed every year before 1970. The non-classic form of the disorder was diagnosed more often in women than in men, which accounts for the female preponderance in our cohort.

INTERPRETATION

Our findings suggest that, contrary to current belief, boys and girls with salt-wasting congenital adrenal hyperplasia were equally missed clinically. Neonatal screening improved detection of the salt-wasting form in girls as well as boys, saving lives in both sexes. The non-classic form was diagnosed more often in women than it was in men, leading to the female preponderance in this cohort.

Adrenal rest tissue in gonads of patients with classical congenital adrenal hyperplasia: multicenter study of 45 French male patients

OBJECTIVES

Several cases of testicular adrenal rest tumours have been reported in men with congenital adrenal hyperplasia (CAH) due to the classical form of 21-hydroxylase deficiency but the prevalence has not been established. The aims of this report were to evaluate the frequency of testicular adrenal rest tissue in this population in a retrospective multicentre study involving eight endocrinology centres, and to determine whether treatment or genetic background had an impact on the occurrence of adrenal rest tissue.

MATERIAL AND METHODS

Testicular adrenal rest tissue (TART) was sought clinically and with ultrasound examination in forty-five males with CAH due to the classical form of 21-hydroxylase deficiency. When the diagnosis of testicular adrenal rest tumours was sought, good observance of treatment was judged on biological concentrations of 17-hydroxyprogesterone (17OHP), delta4-androstenedione, active renin and testosterone. The results of affected and non-affected subjects were compared.

RESULTS

TART was detected in none of the 18 subjects aged 1 to 15years but was detected in 14 of the 27 subjects aged more than 15years. Five patients with an abnormal echography result had no clinical signs. Therapeutic control evaluated at diagnosis of TART seemed less effective when diagnosis was made in patients with adrenal rest tissue compared to TART-free subjects. Various genotypes were observed in patients with or without TART.

CONCLUSION

Due to the high prevalence of TART in classical CAH and the delayed clinical diagnosis, testicular ultrasonography must be performed before puberty and thereafter regularly during adulthood even if the clinical examination is normal.

Steroid 21 hydroxylase deficiency congenital adrenal hyperplasia

Steroid 21 hydroxylase deficiency is the most common form of congenital adrenal hyperplasia (CAH). The severity of this disorder depends on the extent of impaired enzymatic activity, which is caused by various mutations of the 21 hydroxylase gene. This article reviews adrenal steroidogenesis and the pathophysiology of 21 hydroxylase deficiency. The three forms of CAH are then discussed in terms of clinical presentation, diagnosis and treatment, and genetic basis. Prenatal diagnosis and treatment are also reviewed. The goal of therapy is to correct the deficiency in cortisol secretion and suppress androgen overproduction. Glucocorticoid replacement has been the mainstay of treatment for CAH, but new treatment strategies continue to be developed and studied.

Comparison of multiple steroid concentrations in serum and dried blood spots throughout the day of patients with congenital adrenal hyperplasia

BACKGROUND/AIM

periodic measurement of plasma concentrations of cortisol precursors on a clinic visit may be of limited value in patients with congenital adrenal hyperplasia because it does not reflect a patient's circadian patterns of adrenal steroid secretion. Steroid profiling in dried blood spots (DBS) may allow for more frequent and sensitive monitoring.

METHODS

we compared the agreement between 17α-hydroxyprogesterone (17-OHP) and androstenedione (D4A) levels determined from DBS samples and concurrently collected serum samples. Blood was drawn from 9 congenital adrenal hyperplasia patients every 4 h over a 24-hour period. Serum and DBS steroid levels were measured by liquid chromatography tandem mass spectrometry.

RESULTS

DBS determinations of 17-OHP overestimated corresponding serum levels (mean difference 1.67 ng/ml), and underestimated D4A serum levels (mean difference 0.84 ng/ml). However, the DBS assay yielded excellent agreement (97%) with serum 17-OHP, but did considerably poorer for D4A (31%).

CONCLUSIONS

our results indicate an excellent agreement between DBS and serum 17-OHP measurements to identify the peaks and troughs associated with an individual's circadian pattern. Larger-scale studies are required to evaluate the utility of DBS for home monitoring and to determine if more frequent monitoring leads to improved clinical outcomes.

Leukoencephalopathy in 21-beta hydroxylase deficiency: report of a family

21-hydroxylase deficiency is the most common cause of congenital adrenal hyperplasia, an autosomal recessive disorder characterized by impaired synthesis of cortisol from cholesterol by the adrenal cortex. Subclinical involvement of brain white matter has been reported in subjects with congenital adrenal hyperplasia. Here we report a woman with a genetically assessed classic congenital adrenal hyperplasia and brain white matter abnormalities. Both the carrier parents also showed signs of leucoencephalopathy. Common causes of leukoencephalopathy were excluded by appropriate analyses. Our observation suggests that white matter anomalies may also be present in carriers of a mutation in the CYP21 gene. We therefore suggest performing CYP21 gene analysis in subjects with brain MRI evidence of white matter abnormalities that cannot otherwise be explained.

Intersexuality and alternative gender categories in non-Western cultures

BACKGROUND

In the Western world, it is widely accepted as natural - and seen almost as a law of nature - that mankind is divided into two sexes or genders - males and females. In many cultures and societies, however, more than two sex and/or gender categories are recognized, which in some instances refer to the biological sex and in others to gender roles and social status.

AIMS

To give an intercultural comparison of various ways of dealing with gender variance.

METHODS

In the following paper, we review the anthropological literature during the last 100 years describing individuals who live neither as men nor women in various non-Western cultures.

RESULTS

Only rarely, these individuals suffer from disorders of sex development in the modern medical or biological definition: in many if not all societies there have been individuals who are not covered by the gender category of male and female.

CONCLUSION

There thus appears to be a cultural need for people with a special neither-male-nor-female status, which might be classified as 'gender variance'.

Congenital adrenal hyperplasia and P450 oxidoreductase deficiency

Congenital adrenal hyperplasia (CAH) comprises a group of autosomal recessive disorders, which are usually due to inactivating mutations in single enzymes involved in adrenal steroid biosynthesis. The characteristics of the biochemical and clinical phenotype depend on the specific enzymatic defect. In 21-hydroxylase and 11beta-hydroxylase deficiency only adrenal steroidogenesis is affected, whereas a defect in 3beta-hydroxysteroid dehydrogenase or 17alpha-hydroxylase also involves gonadal steroid biosynthesis. Recently, mutations in the electron donor enzyme P450 oxidoreductase were identified as the cause of CAH with apparent combined 17alpha-hydroxylase and 21-hydroxylase deficiency, thereby illustrating the impact of redox regulation enzymes on steroidogenesis. P450 oxidoreductase deficiency (ORD) has a complex phenotype including two unique features not observed in any other CAH variant, skeletal malformations and severe genital ambiguity in both sexes. Despite invariably low circulating androgens, females with ORD may present with virilized genitalia and mothers may suffer from virilization during pregnancy. This apparently contradictory finding may be explained by the existence of an alternative pathway in human androgen biosynthesis, with important implications for physiology and pathophysiology. This review discusses the biochemical and clinical presentation and the genetic and functional basis of the currently known CAH variants, with a specific focus on ORD.

Self-reported sexual arousability in women with congenital adrenal hyperplasia

As part of a larger study of psychosexual development and sexual functioning in women with congenital adrenal hyperplasia (CAH), we assessed self-reported sexual arousability with the Sexual Arousability Inventory-Short Form (SAI-SF; Hoon & Chambless, 1998). Compared to their unaffected sisters/female cousins (n = 15), women with CAH (n = 30) reported significantly lower sexual arousability on the SAI, with an effect size, using Cohen's d, of 1.16. For both the CAH women alone and combined with the controls, higher self-reported sexual arousability was significantly associated with (a) relationship status (married or cohabitating with a man versus being single or not in a relationship); (b) higher levels of sexual attraction to men in fantasy in the past 12 months on the Erotic Response and Orientation Scale (Storms, 1980); (c) higher Kinsey interview ratings of a heterosexual orientation in behavior in the past 12 months; and (d) more sexual experiences with men, according to a modified version of the Zuckerman (1973) Heterosexual Experience Scale (HES), in the past 12 months and lifetime (all ps < .001-.05). CAH women who were simple virilizers (versus salt-wasters) and those assigned female at birth (versus delayed or male) tended to report higher levels of sexual arousability (p < .10). Self-reported degree of satisfaction with genital surgery and genital function was also associated with higher levels of arousability. For CAH women and both groups combined, multiple regression analysis showed that the sole predictor of self-reported sexual arousability was HES lifetime sexual experiences with men. We discuss the results in the context of assessing sexual function and dysfunction in women with CAH.

Congenital adrenal hyperplasia due to 21-hydroxylase deficiency--the adult woman

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a disease with a varying phenotype depending on the mutation(s) present and the severity of the disease. All children with CAH need to be continuously cared for from birth or early infancy by specialists in paediatric endocrinology and surgery. Complications due to over- or under-treatment with corticosteroids are often seen during adolescence, and these problems often continue into adulthood. For the young woman with CAH, questions about menstruation, sexuality, fertility and the possible necessity of complementary surgery are always important issues that need to be discussed. To meet the needs of the young woman with CAH, it is important that the transition from paediatric to adult care be a process of parallel consultations over several years, always involving an experienced gynaecologic endocrinologist.

Genetic causes of human infertility

The currently characterized chromosomal disorders and gene mutations that cause infertility in humans were reviewed. Of the four arbitrary compartments, genes expressed in the gonad comprise the most common site affected by mutations causing infertility. Clinicians should be aware of the most common causes that have clinical implications: (1) women with a 45,X cell line commonly have cardiac anomalies that may pose a risk for maternal death in pregnancies achieved by donor egg IVF; (2) men with Y-chromosome deletions may produce male offspring with the same deletion, rendering them infertile; (3) CBAVD must be ascertained in men with azoospermia because of the risk for having a child with CF; and (4) some women with premature ovarian failure may be fragile X syndrome carriers, so other family members may be at risk for the full syndrome. In the future, more genes will be identified to cause infertility in humans, which will translate into clinical significance. In select cases, in which the genetic defect is known, it may be possible to use preimplantation genetic diagnosis to screen embryos prior to uterine transfer.

Endocrine causes of male infertility

Although endocrinopathies are not often seen in infertile men, these disorders are clinically significant; they often have potentially serious medical significance, regardless of fertility issues. Correction of these disorders represents a possible way to restore normal fertility for the male partner. Male fertility is critically dependent upon a normal hormonal milieu. The hypothalamic-pituitary-gonadal axis is quite sensitive to disruption by endocrine disorders and other generalized medical disorders. Thus, male infertility is occasionally the presenting sign for significant underlying medical disease; it is important to properly evaluate these patients.
