Idiopathic hirsutism.

Hirsutism, the presence of terminal (coarse) hairs in females in a male-like pattern, affects between 5% and 10% of women. Of the sex steroids, androgens are the most important in determining the type and distribution of hairs over the human body. Under the influence of androgens hair follicles that are producing vellus-type hairs can be stimulated to begin producing terminal hairs (i.e., terminalized). The activity of local 5alpha-reductase (5alpha-RA) determines to a great extent the production of dihydrotestosterone (DHT), and consequently the effect of androgens on hair follicles. While there are two distinct 5alpha-RA isoenzymes, type 1 and type 2, the activity of these in the facial or abdominal skin of hirsute women remains to be determined. Although the definition of idiopathic hirsutism (IH) has been an evolving process, the diagnosis of IH should be applied only to hirsute patients with normal ovulatory function and circulating androgen levels. A history of regular menses is not sufficient to exclude ovulatory dysfunction, since up to 40% of eumenorrheic hirsute women are anovulatory. The diagnosis of IH, when strictly defined, will include less than 20% of all hirsute women. The pathophysiology of IH is presumed to be a primary increase in skin 5alpha-RA activity, probably of both isoenzyme types, and possibly an alteration in androgen receptor function. Therapeutically, these patients respond to antiandrogen or 5alpha-RA inhibitor therapy. Pharmacological suppression of ovarian or adrenal androgen secretion may be of additional, albeit limited, benefit. New therapeutic strategies such as laser epilation or the use of new biological response modifiers may play an important role in offering a more effective means of treatment to remove unwanted hair. Further investigations into the genetic, molecular, and metabolic aspects of this disorder, including only well defined patients, are needed.

Normal ovulatory women with polycystic ovaries have hyperandrogenic pituitary-ovarian responses to gonadotropin-releasing hormone-agonist testing.

Women with polycystic ovary syndrome (PCOS) have chronic anovulation and hyperandrogenism and frequently have abnormalities in their lipid profiles and insulin/insulin-like growth factor axis that increase their lifetime risk for cardiovascular disease. Normal ovulatory women may have polycystic ovaries on ultrasonography and yet lack the clinical features of PCOS. To further explore whether ovulatory women without clinical/biochemical hyperandrogenism but with polycystic appearing ovaries (ov-PAO) have subclinical features of PCOS, we prospectively characterized 26 ov-PAO women and matched them by age and body mass index to 25 ovulatory women with normal appearing ovaries (ov-NAO) and to 22 women with PCOS. After an overnight fast, all women had baseline endocrine and metabolic assessments. In addition, a subset of each group of women underwent GnRH-agonist (leuprolide acetate 1 mg s.c.) testing, ACTH stimulation, and an insulin tolerance test (ITT). At baseline, ov-PAO and ov-NAO women had similar endocrine profiles (LH, LH:FSH, androstenedione, and DHEAS). Compared with ov-NAO, 31% of ov-PAO women had reduced glucose responses after insulin (K(itt)), suggesting mild insulin resistance, and 35% had high density lipoprotein levels below 35 mg/dL, a level considered to represent significant cardiovascular risk. After GnRH-agonist, ov-PAO women had response patterns in LH, total testosterone, and 17-hydroxyprogesterone (17-OHP) that were intermediate between ov-NAO and women with PCOS. Ovarian responses were above the normal range in 30-40% of women with ov-PAO. In ov-PAO, peak responses of LH after leuprolide correlated with triglyceride levels (P < 0.05) and peak responses of 17-OHP correlated inversely with Kitt values (P < 0.05). No significant differences were noted with ACTH testing. In conclusion, occult biochemical ovarian hyperandrogenism may be uncovered using GnRH-agonist in ovulatory women with ov-PAO, while adrenal responses remain normal. Subtle metabolic abnormalities may also be prevalent.

Do hyperandrogenic women with normal menses have polycystic ovary syndrome?

OBJECTIVE: To determine the prevalence of polycystic ovary syndrome (PCOS) among hyperandrogenic women who report normal menses. DESIGN: Prospective observational study. SETTING: Academic practice in reproductive endocrinology. PATIENT(S): Fifty-eight consecutively seen new patients with hyperandrogenism who reported normal menses. INTERVENTION(S): Ovulatory status was assessed with timed serum progesterone measurements. The following tests also were carried out: vaginal ultrasound examination; measurement of the ovarian response of 17-hydroxyprogesterone (17-OHP) after the administration of leuprolide acetate, 1 mg SC; and determination of fasting serum LH, FSH, E2, 17-OHP, insulin, and androgen levels. MAIN OUTCOME MEASURE(S): Determination of ovulatory status, polycystic appearance of ovaries, and increased response of 17-OHP to leuprolide acetate. RESULT(S): Twelve (20.7%) of the hyperandrogenic women were anovulatory and met the usual criteria for the diagnosis of PCOS. The ovulatory patients had lower serum total and unbound testosterone levels. Thirty-one (53.4%) of the ovulatory women had polycystic ovaries on ultrasound examination and/or an increased 17-OHP response to leuprolide acetate, suggesting the diagnosis of PCOS despite the presence of ovulation. Considering both the anovulatory and ovulatory patients, 74% of the hyperandrogenic women studied could have PCOS. CONCLUSION(S): The data suggest that most (74%) hyperandrogenic women who report normal menses have evidence for the diagnosis of PCOS.

Evidence that insulin and androgens may participate in the regulation of serum leptin levels in women.

OBJECTIVE: Although serum leptin is principally influenced by body mass, to understand the role of insulin and androgens in the regulation of serum leptin in normal weight women. DESIGN: Prospective observational study. SETTING: Academic practice in reproductive endocrinology. PATIENT(S): Twenty-one women with polycystic ovary syndrome (PCOS) of normal body weight, 8 apparently normal women with polycystic-appearing ovaries (PAO), and 21 normal women. INTERVENTION(S): Fasting blood levels of luteinizing hormone, follicle-stimulating hormone, testosterone (T), unbound T, dehydroepiandrosterone sulfate (DHEAS), insulin, insulin growth factor-binding protein-1 (IGFBP-1), and leptin. MAIN OUTCOME MEASURE(S): Comparisons of measured hormones in the different groups and correlative analysis RESULT(S): Women with PCOS had higher levels of serum luteinizing hormone, T, unbound T, DHEAS and insulin, and lower levels of IGFBP-1 compared with the normal controls, but they had similar leptin levels. Normal women with PAO had increased levels of insulin and leptin compared with controls, whereas IGFBP-1 was lower in PAO. In normal weight women with PCOS and PAO, leptin correlated positively with body weight and insulin, and negatively with IGFBP-1 and DHEAS. CONCLUSION(S): In normal weight patients serum leptin levels may be regulated in part by insulin. Androgens, on the other hand, may play a role in suppressing serum leptin.

The contributions of oestrogen and growth factors to increased adrenal androgen secretion in polycystic ovary syndrome.

Adrenal hyperandrogenism is prevalent in many women with polycystic ovary syndrome (PCOS), although the expression of this enhanced secretion may be heterogeneous. Since no single factor acts in isolation, this study was performed to assess the influence of oestradiol (total and unbound), insulin, insulin-like growth factor (IGF)-I, IGF-II and the binding proteins IGFBP-I, and IGFBP-3, on basal and adrenocorticotrophic hormone (ACTH) stimulated adrenal androgen secretion in 25 women with PCOS and 10 matched ovulatory controls. Women with PCOS exhibited elevations of all androgens as well as unbound oestradiol, insulin and non-IGFBP-1 bound IGF-I. Positive correlations were noted between oestrogen and basal and ACTH stimulated delta 5 adrenal androgens. Serum IGF-I was only correlated with basal dehydroepiandrosterone sulphate (DHEA-S), while insulin exhibited a strong correlation with the delta 4 pathway and androstenedione formation in particular. This correlation was also confirmed by dividing the PCOS group into those women with and without hyperinsulinaemia. The activity of 17,20 lyase favouring androstenedione was increased in the hyperinsulinaemic women. By multivariate analyses, body mass index did not influence these findings. Although there are inherent difficulties in making major conclusions based on correlative analyses, it is suggested that oestrogen may have a greater influence on enhancing delta 5 adrenal androgen secretion, and insulin a greater effect on the delta 4 pathway. In turn, the relative importance of these influences may contribute to the heterogeneous nature of adrenal hyperandrogenism in PCOS.

The addition of dexamethasone to antiandrogen therapy for hirsutism prolongs the duration of remission.

OBJECTIVE: To determine whether the addition of dexamethasone to antiandrogen therapy prolongs the duration of remission in women with hirsutism. DESIGN: Follow-up study of patients treated with one of four regimens: spironolactone (100 mg/d) for 1 year, dexamethasone (0.37 mg/d) for 1 year, dexamethasone (0.37 mg/d) plus spironolactone (100 mg/d) for 1 year, or dexamethasone (0.37 mg/d) plus spironolactone (100 mg/d) for 2 years. SETTING: Academic medical practice in reproductive endocrinology. PATIENT(S): Fifty-four women with hirsutism and hyperandrogenism. INTERVENTION(S): Ferriman-Gallwey-Lorenzo scores were obtained and serum levels of testosterone, unbound testosterone, and dehydroepiandrosterone sulfate were measured before therapy, every 6 months during therapy, and for 1 year after the withdrawal of therapy. MAIN OUTCOME MEASURE(S): Hirsutism scores and serum indices of hormonal changes were monitored. RESULT(S): Ferriman-Gallwey-Lorenzo scores and androgen levels remained low 1 year after the withdrawal of therapy in patients who were treated with dexamethasone, either alone or in combination with spironolactone. In patients who were treated with spironolactone alone, hirsutism scores had returned to baseline values after 1 year. CONCLUSION(S): The addition of an agent that suppresses androgen levels may be useful to prolong the duration of remission of hirsutism in women with hyperandrogenism who are treated with antiandrogens.

Prevalence of idiopathic hirsutism.

OBJECTIVE: To evaluate the prevalence of idiopathic hirsutism in a large population of hirsute women. DESIGN: 588 hirsute women (mean age 24+/-1, range 15-36 years) were evaluated as outpatients at the Department of Endocrinology of the University of Palermo, Italy. The diagnosis of idiopathic hirsutism was established in hirsute patients presenting regular ovulatory menstrual cycles and normal serum androgen levels (total testosterone, unbound testosterone and dehydroepiandrosterone sulfate). METHODS: Hirsutism was calculated by the Ferriman-Gallwey-Lorenzo index. Serum androgens were evaluated in the follicular phase (days 5 or 6) and normal androgen ranges were calculated as the mean+/-2S.D. of serum levels of 30 ovulatory non-hirsute women. The presence of ovulation was determined by serum progesterone levels during the presumed luteal phase (days 21 or 22). All steroids were determined by specific RIAs. RESULTS: 36 hirsute women (6%) had regular ovulatory cycles and normal androgen levels and were diagnosed as being affected by idiopathic hirsutism. CONCLUSIONS: Idiopathic hirsutism is a relatively uncommon cause of hirsutism, affecting approximately 6%, of our population.

Gonadotrophin-releasing hormone agonist therapy for hirsutism is as effective as high dose cyproterone acetate but results in a longer remission.

Both cyproterone acetate (CPA) and the gonadotrophin-releasing hormone agonist (GnRHa) have been shown to be effective for the treatment of hirsutism. We wished to compare the effectiveness of CPA in two standard doses with GnRHa and add-back therapy and to compare the length of remission after these treatments. A total of 60 hirsute hyperandrogenic women was assigned to the following treatment groups: CPA 2 mg with 35 microg of ethinylestradiol for 21 days each month (Diane group), CPA 50 mg, days 5-15, and ethinylestradiol 50 microg, days 5-25, each month (CPA group) or Decapeptyl 3.75 mg i.m. every 28 days with the addition of conjugated oestrogen 0.625 mg, days 1-21, and medroxyprogesterone acetate 10 mg, days 12-21 (GnRHa group). Hirsutism was graded by the Ferriman-Gallwey-Lorenzo (FGL) index and anagen hair shaft diameters and serum luteinizing hormone (LH) and testosterone were assessed before and every 3 months during and after treatment. All women were treated for 1 year with 1 year follow-up. At baseline hirsutism and endocrine patterns were similar in all groups. After one year of treatment, hirsutism decreased in all groups but the changes were greater (P <0.05) in the CPA and GnRHa groups than in the Diane group. Serum LH and testosterone were lowest in the GnRHa group. After withdrawal, hirsutism increased rapidly in the Diane and CPA groups and after 6 months, FGL scores and hair shaft diameters were similar to pretreatment values. In the GnRHa group, hirsutism increased more gradually and after 1 year of withdrawal, FGL scores and hair diameters were significantly (P <0.05) less than pretreatment values. Serum LH and testosterone increased rapidly in all three groups reaching pretreatment values by 6 months. These data suggest equal efficacy of the GnRHa and the high dose CPA regimen for the treatment of hirsutism in hyperandrogenic women. GnRHa with add-back treatment appears to result in a longer remission of hirsutism in comparison with CPA.

Endocrine abnormalities in ovulatory women with polycystic ovaries on ultrasound.

Polycystic-appearing ovaries (PAO) on ultrasound have been described in a variety of endocrinopathies and also occur in ovulatory women. By some investigators this is merely referred to as 'PCO' (polycystic ovaries). Although there is controversy in this regard, we do not consider women with PAO/PCO who have no known endocrine disturbance to have polycystic ovary syndrome (PCOS) and therefore prefer not to use the term 'PCO' which is often equated with PCOS. We studied 15 ovulatory women with normal-appearing (NAO) ovaries on ultrasound and 15 matched ovulatory women with PAO/PCO. Compared to ovulatory women, 25 other women were studied who were considered to have PCOS. Of these, 15 were overweight and 10 were of normal weight. All the PCOS women had serum concentrations of luteinizing hormone (LH), testosterone, unbound testosterone, androstenedione and dihydroepiandrosterone sulphate (DHEAS) which were significantly higher (P < 0.01) than values in the normal women, regardless of ovarian morphology. These values were similar in the two groups of ovulatory women with NAO and PAO/PCO. Fasting insulin was elevated in women with PCOS with increased body weight (P < 0.01) and was higher than in ovulatory women with NAO and PAO/PCO and than in women of normal weight with PCOS. Serum insulin-like growth factor (IGF)-I and binding protein (BP)-3 were similar in all groups but serum IGFBP-1 was significantly (P < 0.01) lower in those women with PCOS with increased body weight, compared to all other groups. Compared to values in ovulatory women with NAO, serum IGFBP-1 was also significantly (P < 0.05) lower in women with PAO/PCO and those women with PCOS of normal weight. These lower values were similar in women with PAO/PCO and in normal weight women with PCOS. On an individual basis, an elevation of at least one serum androgen value was found in 33% of women with PAO/PCO. These data confirm that increased body weight accentuates the metabolic alterations in PCOS, but suggest that subtle endocrine disturbances, similar to those that are found in PCOS, may be uncovered in up to a third of ovulatory women with PAO/PCO. It appears that a disturbance of the IGF/IGFBP-1 axis is common and apparently closely associated with alterations in ovarian morphology.

Reassessment of adrenal androgen secretion in women with polycystic ovary syndrome.

OBJECTIVE: To reevaluate the clinical significance of elevations of adrenal androgens in polycystic ovary syndrome (PCOS). METHODS: Thirty women with PCOS and ten ovulatory controls were evaluated. Serum dehydroepiandrosterone (DHEA) sulfate and 11 beta-hydroxyandrostenedione were measured before and after 3 and 6 months of GnRH agonist (GnRH-A) therapy. All controls and 15 women with PCOS received intravenous ACTH before and after GnRH-A therapy. RESULTS: Twenty-one (70%) of the women with PCOS had elevations of DHEA sulfate, and 16 (53%) had elevations in 11 beta-hydroxyandrostenedione. Only two women with PCOS had normal values of both adrenal androgens. After GnRH-A therapy, only 11 subjects (37%) had elevated values of DHEA sulfate. Four of 16 women had reductions in 11 beta-hydroxyandrostenedione. Only those with elevated baseline DHEA sulfate levels had reductions after GnRH-A therapy. The reduction of DHEA sulfate with GnRH-A correlated with the reduction in androstenedione. Of the subjects who had reductions in DHEA sulfate with GnRH-A therapy, there was a blunted response of DHEA to ACTH after treatment. CONCLUSION: Our findings suggest that the ovary may influence the prevalence and magnitude of adrenal androgen excess in PCOS.

Alterations in the sensitivity of serum insulin-like growth factor 1 and insulin-like growth factor binding protein-3 to octreotide in polycystic ovary syndrome.

OBJECTIVE: To determine if the somatostatin analog, octreotide, affects insulin and related peptides and, hence, androgen levels differently between polycystic ovary syndrome (PCOS) patients and controls. DESIGN: Prospective controlled trial. SETTING: Reproductive endocrinology clinic of our medical center. PATIENTS: Eleven women with PCOS and six matched ovulatory controls. INTERVENTIONS: Octreotide (100 micrograms) was administered subcutaneously in the midfollicular phase. Serum was obtained before and at 60, 120, 180, and 240 minutes after octreotide. MAIN OUTCOME MEASURES: Fasting insulin, insulin-like growth factor 1 (IGF-1), insulin-like growth factor binding protein-3 (IGFBP-3), T, androstenedione (A), and LH. RESULTS: In PCOS, baseline levels of T, A, LH, and fasting insulin were significantly higher than in controls. Pretreatment IGF-1 and IGFBP-3 levels were similar in PCOS and controls. Octreotide reduced fasting insulin levels significantly but to a similar degree in control and PCOS patients (77% and 90%, respectively). Both groups also experienced a significant decrease in LH levels after octreotide administration, but no significant changes were demonstrated in serum T or A. However, serum IGF-1 suppression in PCOS was greater (63% versus 8% in controls). Serum IGFBP-3 levels increased after octreotide administration in both groups with a larger increase (40%) occurring in the PCOS patients. CONCLUSIONS: These data suggest that women with PCOS may be more sensitive to the effects of octreotide in decreasing IGF-1 and increasing IGFBP-3. Although no significant changes could be demonstrated in ovarian androgens after a single dose, octreotide effectively reduced serum LH and insulin and, as such, may prove useful in treating some patients with PCOS.

Substrate dependency of C19 conjugates in hirsute hyperandrogenic women and the influence of adrenal androgen.

Serum C19 conjugates, specifically 3 alpha-androstanediol glucuronide (3 alpha G), reflect peripheral androgen action through the action of 5 alpha-reductase activity. The origin of 5 alpha-reduced C19 conjugates has been controversial and it has been suggested that they are derived primarily from adrenal androgens. We examined concentrations of 3 alpha G, 3 alpha-androstanediol sulphate (3 alpha S), androsterone glucuronide (AoG) and androsterone sulphate (AoS) in 40 hirsute hyperandrogenic women. These patients were divided into four groups based upon individual, combined or normal concentrations of the adrenal androgens dehydroepiandrosterone (DHEAS) and 11 beta-hydroxy-androstenedione. Testosterone, unbound testosterone and androstenedione were similar in these groups. Serum 3 alpha G was equally high in all groups and was correlated significantly with hirsutism, while the other conjugates were not. Androsterone glucuronide was raised in all groups but was higher in patients with raised DHEAS. Serum 3 alpha S was raised in all groups and was higher where both adrenal androgens were raised. Serum AoS was highly correlated with DHEAS. Serum 3 alpha G was correlated with unbound testosterone and androstenedione but not with the adrenal androgens. The glucuronide conjugates were correlated with one another as were the sulphate conjugates but glucuronides and sulphates were not correlated. These data confirm ovarian and adrenal dependency of C19 conjugates. Serum 3 alpha G appears to reflect hirsutism most accurately and is least dependent on adrenal androgens in patients with mixed hyperandrogenism.

Time-dependent changes in serum 3 alpha-androstanediol glucuronide correlate with hirsutism scores after ovarian suppression.

The clinical utility of serum 3 alpha-androstanediol glucuronide level has been controversial. Among the concerns regarding its lack of utility has been the finding that suppression of serum 3 alpha-androstanediol glucuronide does not occur readily with treatment. We hypothesized that because the treatment of hirsutism requires a prolonged duration, a longer observation period is required for changes in serum 3 alpha-androstanediol glucuronide to be measured. Therefore, we studied the clinical and hormonal changes in 11 women treated for hirsutism with a gonadotropin-releasing hormone agonist (GnRH-a) for 1 year. A progressive reduction in Ferriman-Gallwey scores occurred, which was significant at 6 weeks and was maximal at 12 months. Serum 3 alpha-androstanediol glucuronide and another peripheral marker, androsterone glucuronide, also fell commensurately. While there was no correlation at 3 months, by 6 weeks a significant correlation had occurred between the suppression in Ferriman-Gallwey scores and the suppression of serum 3 alpha-androstanediol glucuronide and androsterone glucuronide. The suppression of these steroids also correlated with the suppression of non-sex hormone-binding globulin-bound testosterone. These data confirm that markers of peripheral androgen action, particularly serum 3 alpha-androstanediol glucuronide, reflect the clinical manifestation of hirsutism. However, it appears that modifications in peripheral androgen activity (presumably through 5 alpha-reductase activity) are time-dependent, and that serum markers reflect changes after 6 months of treatment.

Ovarian suppression reduces clinical and endocrine expression of late-onset congenital adrenal hyperplasia due to 21-hydroxylase deficiency.

OBJECTIVE: To determine the effectiveness of GnRH-agonist (GnRH-a) treatment in women with late onset congenital adrenal hyperplasia. DESIGN: Prospective assessment of GnRH-a treatment in six women with documented late-on-set congenital adrenal hyperplasia who were not preselected. Comparisons were made to previous responses in the same patients receiving dexamethasone. Eight age- and weight-matched ovulatory women served as controls. SETTING: Academic medical center. INTERVENTION: Baseline blood determinations before and after i.v. ACTH, before and after 6 months of GnRH-a treatment. Estrogen and progestin replacement was begun in all women after the 3rd month of treatment. MAIN OUTCOME MEASURES: Serum 17-hydroxyprogesterone (17-OHP), gonadotropin, and androgen levels before and after GnRH-a treatment. Responses of 17-OHP and androgens to ACTH assessment of hirsutism using a modified Ferriman-Gallwey score. RESULTS: Gonadotropins, estrogen, androgen, and 17-OHP were suppressed with GnRH-a treatment. Levels were similar before and after estrogen and progestin replacement. Responses of 17-OHP after ACTH were blunted but still were elevated compared with responses in controls. Ferriman-Gallwey scores decreased significantly (-8 +/- 1; mean +/- SE). This response was greater than that observed previously with 6 months of dexamethasone (-2 +/- 0.3). CONCLUSIONS: Suppression of the ovary with GnRH-a treatment was beneficial in these patients with late-onset congenital adrenal hyperplasia. An ovarian influence on the clinical and biochemical findings of the disorder is suggested.

Alterations in androgen conjugate levels in women and men with alopecia.

OBJECTIVE: To assess levels of androgen metabolites thought to reflect, at least in part, peripheral androgen activity in women with androgenic alopecia and men with premature balding in an effort to determine if a common abnormality exists. DESIGN: Prospective study in various groups of women and men. SETTING: Reproductive Endocrine Clinic at our university medical center. PATIENTS: Ten normal ovulatory female controls and 50 hyperandrogenic women divided on the basis of hirsutism and alopecia as follows: [1] 8 hirsute women with androgenic alopecia; [2] 12 nonhirsute women with androgenic alopecia; [3] 18 hirsute women without androgenic alopecia; and [4] 12 nonhirsute women without androgenic alopecia. Ten normal men and 10 young premature balding men matched for age and weight also were compared. INTERVENTION: Blood was obtained from all subjects. MAIN OUTCOME MEASURE: Comparison of blood hormone levels in the various groups. RESULTS: Serum T, androstenedione, and DHEAS were similarly elevated in hyperandrogenic women with and without alopecia, compared with controls. The female groups were then divided on the basis of hirsutism. Hirsute groups with and without alopecia had similarly elevated levels of unconjugated 3 alpha-androstanediol, 3 alpha-androstanediol glucuronide, 3 alpha-androstanediol sulfate, androsterone glucuronide, and androsterone sulfate compared with controls. In the nonhirsute groups, androgenic alopecia patients were compared with hyperandrogenic females and cycling controls. The androgenic alopecia patients had elevated levels of 3 alpha androstanediol (0.75 +/- 0.12 versus 0.46 +/- 0.1 and 0.41 +/- 0.1 nmol/L), 3 alpha-androstanediol sulfate (200 +/- 31 versus 79.6 +/- 6 and 67.0 +/- 4.0 nmol/L), elevated ratios of 3 alpha-androstanediol sulfate:3 alpha-androstanediol (267 +/- 49 versus 170 +/- 20 and 164 +/- 49 nmol/L), elevated ratios of 3 alpha-androstanediol sulfate:3 alpha-androstanediol glucuronide (32.2 +/- 6 versus 10.8 +/- 1 and 10.0 +/- 1) and lower ratios of 3 alpha-androstanediol glucuronide:3 alpha-androstanediol glucuronide (8.3 +/- 1.8 versus 17 +/- 1.7 and 15.2 +/- 1.6 nmol/L). In men the premature balding group had lower levels of 3 alpha-androstanediol glucuronide compared with the male controls (29.8 +/- 4.4 versus 15.2 +/- 1.6 nmol/L). Also, the ratio of 3 alpha-androstanediol glucuronide:3 alpha-androstanediol was significantly decreased, whereas the ratio of 3 alpha-androstanediol sulfate:3 alpha-androstanediol glucuronide was elevated. CONCLUSIONS: These data provided evidence confirming that enhanced 5 alpha-reductase activity occurs in androgenic alopecia but also suggests that a disorder of androgen conjugation, favoring sulfurylation over glucuronidation, may be a characteristic feature of scalp hair loss.
