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.

Low-dose growth hormone-releasing factor may enhance folliculogenesis in regularly menstruating women: a preliminary study.

OBJECTIVE: To evaluate the effect of low-dose GH-releasing factor (GRF) on folliculogenesis in regularly menstruating women. DESIGN: Prospective clinical trial where individual patients served as their own control. SETTING: Outpatient Reproductive Endocrine/Infertility Clinic of the Los Angeles County-University of Southern California Medical Center, Los Angeles, California. PATIENTS: Seven regularly menstruating women. INTERVENTION: During treatment cycles, subjects received 100 micrograms SC GRF on cycle days 2 to 11 and were observed during a control cycle. MAIN OUTCOME MEASURES: Follicle number and diameter, as well as endometrial thickness were all assessed by vaginal ultrasound and blood was obtained for serum FSH, LH, E2, P, GH, insulin-like growth factor 1 (IGF-1), and insulin-like growth factor binding protein-3. RESULTS: During cycles treated with GRF, GH, and IGF-1 levels were normal. However, follicular growth rates and E2 to FSH ratios were significantly higher. The day of the peak E2 to follicular diameter ratio after GRF was earlier than in control cycles. Endometrial growth rates were also greater with GRF. CONCLUSIONS: Our data, although preliminary, support the hypothesis that low doses of GRF may independently stimulate the ovary and enhance folliculogenesis.

A dopamine D3 receptor genotype is associated with hyperandrogenic chronic anovulation and resistant to ovulation induction with clomiphene citrate in female Hispanics.

OBJECTIVE: To determine if dopamine (D3) receptor genotypes are associated with anovulation and response to ovulation induction with clomiphene citrate. DESIGN: Clinical and laboratory characteristics of anovulatory patients and ovulatory controls were compared with findings at the DNA level. SETTING: An outpatient clinic at an university medical center. PATIENTS: One hundred eighty human Hispanic female volunteers (130 of these with documented ovulatory status) were studied. INTERVENTIONS: Genomic DNAs were extracted from each patient. Polymerase chain reaction with subsequent restriction digest was performed to analyze the D3 receptor allele status (two possible alleles). MAIN OUTCOME MEASURES: Menstrual history, serum T, and midluteal serum Ps from spontaneous and clomiphene cycles were correlated with D3 receptor genotype. RESULTS: Hispanic females with the 22 genotype compared with the other genotypes (11 and 12) were more likely to have irregular menses, an elevated serum T (> or = 70 ng/dL [conversion factor to SI unit, 3.467]), and hyperandrogenic chronic anovulation. These patients tended to be resistant to ovulation induction requiring a significantly higher dose of clomiphene to achieve an ovulatory response (22 genotype [mean +/- SEM] [140.0 +/- 19.0 mg] versus 11 [77.1 +/- 17.5 mg] or 12 [69.2 +/- 13.1 mg]). This effect was independent of patient age, weight, or serum T level. CONCLUSIONS: Hyperandrogenic chronic anovulation may have a genetic component. Genetic analysis may be useful in predicting resistance to ovulation induction with clomiphene.

Metabolism of dihydrotestosterone to 5 alpha-androstane-3 alpha, 17 beta-diol glucuronide is greater in the peripheral compartment than in the splanchnic compartment.

OBJECTIVE: To compare the peripheral versus the splanchnic contribution to the formation of 3 alpha-diol G. DESIGN: Prospective study in various groups of women and men. SETTING: Reproductive Endocrine service of our University Medical Center. PATIENTS: Six normal ovulatory women, five hirsute women with polycystic ovary syndrome, and six normal men. INTERVENTIONS: All subjects received IV dihydrotestosterone (DHT) infusions as well as percutaneous administration of DHT. Serum was obtained at multiple time points before and after each administration of DHT. MAIN OUTCOME MEASURES: Comparison of serum levels of DHT, 3 alpha-androstanediol (3 alpha-diol), 3 alpha-diol G, and androsterone glucuronide in the three groups. RESULTS: Steady-state levels of DHT were similar in the three groups and were also similar after the two different routes of administration. However, ratios of 3 alpha-diol G to DHT were significantly greater after percutaneous gel than after IV administration in all three groups. This also was the case for the ratio of unconjugated serum 3 alpha-diol to DHT. Levels of androsterone glucuronide were similar with the different routes of administration. CONCLUSION: Using normal routes of administration and, in attempting to assess in vivo metabolism of DHT, our data confirm that the skin is the major site of unconjugated 3 alpha-diol and 3 alpha-diol G formation. Serum 3 alpha-diol G, therefore, appears largely to reflect skin DHT metabolism.

Prorenin is elevated in polycystic ovary syndrome and may reflect hyperandrogenism.

OBJECTIVE: To examine the null hypothesis that women with polycystic ovary syndrome (PCOS) produce similar levels of prorenin and other components of the ovarian-derived prorenin to angiotensin cascade (ODPAC) at baseline and after stimulation with clomiphene citrate (CC) or hMG when compared with normal age- and weight-matched ovulatory controls. DESIGN: Prospective controlled clinical trial. SETTING: Infertility clinic in a university-based county hospital and a hospital-based private infertility practice. PATIENTS: Twenty-eight infertile women aged 18 to 35 years. Thirteen patients were diagnosed with PCOS. Fifteen normal ovulatory patients who were matched for age and weight served as controls. INTERVENTIONS: Twenty patients were stimulated with CC and eight were stimulated with hMG. MAIN OUTCOME MEASURES: Serum E2, P, T, androstenedione (A), DHEAS, LH, FSH, and plasma prorenin, active renin, and angiotensin II (Ang II) were measured at baseline and during the preovulatory and midluteal phases of the stimulation cycles. RESULTS: Baseline plasma prorenin in PCOS was higher than that of follicular phase controls. Plasma prorenin correlated significantly with peripheral androgen levels. Prorenin, active renin, and Ang II increased in response to gonadotropins with the largest increases occurring in control patients receiving CC. An association was seen between ovulation with CC and lower baseline levels of active renin. CONCLUSIONS: The null hypothesis was rejected. Infertile women with PCOS have higher baseline prorenin levels when compared with age- and weight-matched ovulatory controls. There is a significant correlation between prorenin and the peripheral levels of androgens produced during ovarian stimulation. Baseline active renin levels may be predictive of ovulation with CC.

Preimplantation adoption: establishing pregnancy using donated oocytes and spermatozoa.

The experience of transferring embryos produced through in-vitro fertilization (IVF) utilizing donated oocytes and spermatozoa is described. Recipients (n = 28; aged 38-59 years) received oral micronized oestradiol and i.m. progesterone and were synchronized to donors undergoing ovarian stimulation. Reasons for selecting therapy included advanced reproductive age (> 42 years; n = 21) or hypergonadotrophic hypogonadism (n = 7), combined with severe male factor infertility in 23 couples. Five women were single and without partners. Oocytes were fertilized by cryopreserved spermatozoa designated for use by the recipient. Up to five embryos were transferred transcervically. Supernumerary embryos were cryopreserved. A total of 36 aspirations produced 15.6 +/- 7.3 oocytes per retrieval. In 10/36 cycles (27.8%), embryos were available for cryopreservation. Using fresh embryos, the overall pregnancy rate was 38.9% (14/36), clinical pregnancy rate 33.3% (12/36), and ongoing/delivered pregnancy rate 30.6% (11/36). Three ongoing pregnancies were later established by transferring cryopreserved embryos. Adjusting for these events, the per aspiration overall pregnancy rate per retrieval was 47.2%, clinical pregnancy rate 41.7%, and ongoing/delivered pregnancy rate 38.9%. Implantation rates per individual embryo transferred were 16.6% following fresh embryo transfer. A viable pregnancy was achieved by 14 of 28 women (50% cumulative pregnancy rate). We conclude that using donor oocytes and donor spermatozoa is efficacious and allows couples of whom both members suffer from severe gamete abnormalities and single functionally agonadal women an effective means of achieving pregnancy.

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.

Altered responses to stress in women undergoing in-vitro fertilization and recipients of oocyte donation.

Clinical impressions suggest the presence of considerable anxiety and depression in infertile couples. We utilized a psychological stress test to assess adaptations to provoked stress to improve the psychological profile of infertile women. A psychological stress test was administered to four groups: normal menstruating females (controls, n = 13); oocyte donors (n = 13); recipients of oocyte donation (n = 7); and women undergoing standard in-vitro fertilization (IVF; mean age 38.0 years; n = 8). The psychological stress test consisted of three active coping tasks: (i) serial subtraction, (ii) Stroop colour test, (iii) speech task and (iv) one passive coping task, the cold-pressor test. Haemodynamic responses (HD) were monitored before, during and after the psychological stress test, and serum samples were drawn for catecholamines and cortisol. Baseline blood pressures were similar among groups. The psychological stress test elicited different biophysical responses in controls compared with the other groups (P < 0.001). Oocyte donors had different speech task responses from baseline, although these and the other parameters of the psychological stress test were not different from either the recipient or IVF groups. Blood pressure responses from baseline were blunted in both recipients and standard IVF patients following provoked stress. Baseline cortisol and norepinephrine were similar among all groups, yet provoked stress elicited a significant increase in controls (142.0 +/- 25.2%, P < 0.001) compared with oocyte donors (17.1 +/- 19.7%), recipients and standard IVF patients (mean -15.5 +/- 17.3% respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

Isolated polycystic morphology in ovum donors predicts response to ovarian stimulation.

The isolated finding of polycystic-appearing ovaries on ultrasound examination of normal women is not uncommon. The purpose of this study was to determine the clinical significance of polycystic ovaries in a population of healthy, non-hirsute, fertile women preparing to undergo ovarian stimulation. We evaluated whether the finding of polycystic ovaries in oocyte donors predicts a different response to ovarian stimulation when compared to donors with normal-appearing ovaries. Furthermore, we examined whether oocytes from polycystic ovaries had the same capacity for fertilization and development as those retrieved from normal ovaries. In all, 11 donors with polycystic-appearing ovaries were compared prospectively to 13 donors with normal-appearing ovaries who were undergoing ovarian stimulation during the same time interval. The two groups were similar in age and baseline androgen concentrations. Significantly more oocytes were produced by the polycystic group for the amount of human menopausal gonadotrophin (HMG) administered (P < 0.05). In addition, all previous cycles completed by these 24 donors were compared (polycystic group: total of 31 cycles; normal group: total of 37 cycles). The donors with polycystic ovaries required less HMG to obtain optimal stimulation (P < 0.05), attained a greater peak oestradiol concentration (P < 0.05), produced a greater number of follicles (P < 0.05) and oocytes (P < 0.01) and a higher percentage of mature oocytes (P < 0.05). Furthermore, they achieved a higher peak oestradiol/HMG (P < 0.01) and oocytes/HMG ratio (P < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

Predictive value of serum oestradiol concentrations and oocyte number in severe ovarian hyperstimulation syndrome.

Ovarian hyperstimulation syndrome (OHSS) is a serious complication of gonadotrophin usage but it is difficult to accurately predict its occurrence. Previous investigators have identified the combination of high oestradiol concentrations and oocyte number as being predictive in 80% of cases. In this study we sought to identify the incidence of severe OHSS in patients with high oestradiol concentrations and large numbers of oocytes and to evaluate the importance of pregnancy in the development of OHSS. Between 1990 and 1993, we studied 139 cycles using two assisted reproductive techniques [oocyte donor, n = 72; in-vitro fertilization (IVF), n = 67] in which either oestradiol (> 4000 pg/ml), oocyte number (> 25), or both were elevated. OHSS was diagnosed by standard criteria. There were no cases of severe OHSS in the oocyte donor group and six in the IVF group. Among 10 patients with oestradiol concentration > 6000 pg/ml and > 30 oocytes, only one had OHSS (10%). The relative risk of OHSS with pregnancy was 12 (confidence interval 2.18-66.14). We conclude that the risk of OHSS even at high levels of stimulation is lower than previously believed. Secondly, donors have a very low risk of OHSS, probably because of the absence of pregnancy. As such, cryopreservation of all oocytes in IVF cycles is a reasonable alternative to cycle cancellation or use of adjunctive medication.

A prospective randomized trial comparing finasteride to spironolactone in the treatment of hirsute women.

Enhanced 5 alpha-reductase activity has been found in the skin of the majority of women with hirsutism. Finasteride is a specific competitive inhibitor of 5 alpha-reductase, preferentially inhibiting the type 2 isoenzyme. Therefore, we randomly assigned 14 hirsute women in a 2:1 ratio to 1 of 2 treatment arms: 1) finasteride (F) treatment (n = 9; 5 mg, orally, daily), or 2) spironolactone (S) treatment (n = 5; 100 mg, orally, daily). Each group was treated for 6 months. Patients were evaluated at baseline and after 3 and 6 months of treatment. The 2 groups were similar in age, weight, hip/waist ratio, baseline Ferriman-Gallwey score (F, 19 +/- 2; S, 19 +/- 2), and baseline androgen levels. Finasteride treatment resulted in a significant increase in testosterone (T; P < 0.01) and the T/dihydrotestosterone ratio (P < 0.01). Finasteride caused a significant decrease in 5 alpha-androstane-3 alpha,17 beta-diol glucuronide (3 alpha-diolG; P < 0.05), the 3 alpha-diolG/T ratio (P < 0.01), and the 3 alpha-diolG/androstenedione ratio (P < 0.05). All changes were consistent with 5 alpha-reductase inhibition. In contrast, spironolactone treatment did not result in significant changes in serum hormone levels. Both treatments produced a significant decrease in anagen hair diameters [F, -14.0 +/- 6.7% (P < 0.05); S, -13.4 +/- 3.8% (P < 0.05)] and Ferriman-Gallwey scores [F, -2.1 +/- 0.4 (P < 0.05); S, -2.5 +/- 0.7 (P < 0.05)]. In conclusion, despite significantly different effects on androgen levels, finasteride and spironolactone treatment resulted in a similar clinical effect on hirsutism. Both caused significant, but limited, improvement in hirsutism. Although promising, further studies with finasteride are needed to verify its effectiveness as a treatment for hirsutism. Such studies will also provide a better understanding of the relative contribution of 5 alpha-reductase isoenzymes to hirsutism.

Variations of steroid hormone metabolites in serum and urine in polycystic ovary syndrome after nafarelin stimulation: evidence for an altered corticoid excretion.

To evaluate the clinical relevance of testing pituitary-ovarian responses in patients suffering from polycystic ovary syndrome (PCOS) with the GnRH agonist nafarelin, a 1.2-mg dose of nafarelin was given intranasally to 19 women with PCOS and 15 healthy premenopausal women. The subsequent analysis of steroids in both serum and urine during the test was carried out at several time points for up to 24 h. Serum levels of 17 alpha-hydroxyprogesterone were elevated at all time points of the test in PCOS patients vs. controls [at baseline, 3.5 +/- 0.2 vs. 1.8 +/- 0.1 nmol/L (P < 0.001); at 24 h, 9.9 +/- 0.9 vs. 4.9 +/- 0.3 nmol/L (P < 0.001)]. Basal levels of androstenedione were higher in the patient group, but there was no significant change during the test in either group. Serum testosterone levels were also found to differ in PCOS patients compared with the control values at baseline (2.2 +/- 0.2 vs. 1.5 +/- 0.1 nmol/L; P < 0.05) and after nafarelin treatment (at 24 h, 3.2 +/- 0.4 vs. 1.8 +/- 0.2 nmol/L; P < 0.05). Serum estradiol levels rose significantly in both groups during the test; the posttest levels were significantly higher in PCOS than in controls. The PCOS patients displayed a significant increase in androgen and gestagen metabolites as well as in glucocorticoid metabolites excreted in the urine during the 24 h. In the control subjects, except for 17 alpha-hydroxypregnanolone, which rose significantly, none of the urinary steroids investigated showed relevant changes during the nafarelin test. The posttest excretion of allo-tetrahydrocortisol (1.4 +/- 0.2 vs. 0.3 +/- 0.1 mumol/g creatinine; P < 0.001) and the increase in 17 alpha-hydroxypregnanolone excretion (1.4 +/- 0.2 vs. 0.3 +/- 0.1 mumol/g creatinine; P < 0.001) were distinctly higher in PCOS patients than in the controls; the diagnostic sensitivity of the combination of both parameters was 89% at a 93% specificity. Thus, measurements of 17 alpha-hydroxyprogesterone levels in serum and of urinary allo-tetrahydrocortisol and 17 alpha-hydroxypregnanolone after nafarelin treatment make this stimulation test a valuable diagnostic tool for identifying PCOS patients. The significant changes in the excretion of urinary androgen and gestagen metabolites, unmasked by GnRH agonist stimulation, suggest a functional alteration of the pituitary-ovarian axis. The reason for the increased excretion of glucocorticoid metabolites after nafarelin stimulation remains to be clarified.

The impact of estrogen on adrenal androgen sensitivity and secretion in polycystic ovary syndrome.

Adrenal hyperandrogenism is a common feature of patients with polycystic ovary syndrome (PCO). This may be due to enhanced adrenal sensitivity to ACTH. Because enhanced ovarian androgen secretion does not appear to explain this phenomenon, we explored the role of estrogen in inducing enhanced adrenal sensitivity, in that a state of relative hyperestrogenism exists in PCO. Eight patients with PCO and seven matched controls received ovine corticotropin-releasing hormone (oCRH; 0.1 micrograms/kg) iv before and after hypoestrogenism was induced by leuprolide acetate (LA; 1 mg, sc, each day). In patients with PCO, a third oCRH test was repeated after transdermal estradiol (E2; 0.1 mg) had been applied for a week, during which time LA was continued. At baseline, patients with PCO had increased responses of 11 beta-hydroxyandrostenedione and dehydroepiandrosterone (P < 0.03 and P < 0.02) and increased delta maximal ratios of androstenedione (A4)/ACTH and dehydroepiandrosterone/ACTH (P < 0.01) after oCRH treatment. After LA administration to patients with PCO, these ratios were significantly suppressed (P < 0.01) and returned to baseline after E2 was added. There were no changes in controls. Steroid ratio responses to oCRH suggested that 17,20-desmolase activity (delta maximum change in the ratio of A4/17-hydroxyprogesterone) was lowered with estrogen suppression and increased again after transdermal E2 administration. There was a significant positive correlation between changes in E2 levels and delta maximum change in the ratios of A4/17-OHP after oCRH treatment, signifying 17,20-desmolase activity (r = 0.58, P < 0.02). In conclusion, these data provide evidence that estrogen is at least one factor that influences adrenal androgen sensitivity in PCO and may help explain the frequent finding of adrenal hyperandrogenism in this syndrome.

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.
