Abstract
PURPOSE/BACKGROUND Prolactin-related adverse effects contribute to nonadherence and adverse health consequences, particularly in women with severe mental illness. Treating these adverse effects may improve treatment acceptability, adherence, and long-term outcomes. METHODS/PROCEDURES Premenopausal women with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision diagnosis of schizophrenia, schizoaffective disorder, or bipolar disorder were recruited for a randomized, double-blind, placebo-controlled 16-week trial of adjunct aripiprazole (5-15 mg/d). Participants had elevated prolactin (>24 ng/mL) and were experiencing galactorrhea, amenorrhea, oligomenorrhea, or sexual dysfunction on a prolactin-elevating antipsychotic. Participants were evaluated biweekly for prolactin elevation and galactorrhea and completed a menstrual diary review. Psychiatric symptoms and adverse effects were closely monitored. FINDINGS/RESULTS Forty-six women were randomized (n = 25 aripiprazole, n = 21 placebo). Thirty-seven completed at least 8 weeks of the study (n = 20 [80%] aripiprazole and n = 17 [81%] placebo). Aripiprazole (mean dose, 11.7 ± 2.4 mg/d) was effective for lowering prolactin relative to placebo (P = 0.04). In addition, 45% (9/20) of the aripiprazole group had a normalized prolactin (<24 mg/mL) compared with 12% (2/17) of the placebo group (P = 0.028). Galactorrhea resolved in 77% (10/13) of the aripiprazole-treated participants compared with 33% (4/12) in the placebo group (P = 0.028). Normalization of sexual function (<16 on the Arizona Sexual Experience Scale) occurred in 50% on aripiprazole (7/14) versus 9% (1/11) on placebo (P = 0.030). No differences between groups in symptoms or adverse effects were noted. Overall, women rated a mean score of 4.6 ± 0.6 on a 5-point Likert scale for sexual function improvement, suggesting their particular satisfaction with improvement in this domain. IMPLICATIONS/CONCLUSIONS Building upon prior studies, this rigorous evaluation confirms the utility of adjunctive aripiprazole as a strategy for improving prolactin and managing prolactin-related adverse effects in premenopausal women with psychosis.

Low-dose oral sirolimus and the risk of menstrual-cycle disturbances and ovarian cysts: analysis of the randomized controlled SUISSE ADPKD trial. PLoS One 2012; 7:e45868. [PMID: 23071528 PMCID: PMC3468602 DOI: 10.1371/journal.pone.0045868] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2012] [Accepted: 08/22/2012] [Indexed: 01/05/2023] Open
Abstract
UNLABELLED Sirolimus has been approved for clinical use in non proliferative and proliferative disorders. It inhibits the mammalian target of rapamycin (mTOR) signaling pathway which is also known to regulate ovarian morphology and function. Preliminary observational data suggest the potential for ovarian toxicity but this issue has not been studied in randomized controlled trials. We reviewed the self-reported occurrence of menstrual cycle disturbances and the appearance of ovarian cysts post hoc in an open label randomized controlled phase II trial conducted at the University Hospital Zürich between March 2006 and March 2010. Adult females with autosomal dominant polycystic kidney disease, an inherited kidney disease not known to affect ovarian morphology and function, were treated with 1.3 to 1.5 mg sirolimus per day for a median of 19 months (N = 21) or standard care (N = 18). Sirolimus increased the risk of both oligoamenorrhea (hazard ratio [HR] 4.3, 95% confidence interval [CI] 1.1 to 29) and ovarian cysts (HR 4.4, CI 1.1 to 26); one patient was cystectomized five months after starting treatment with sirolimus. We also studied mechanisms of sirolimus-associated ovarian toxicity in rats. Sirolimus amplified signaling in rat ovarian follicles through the pro-proliferative phosphatidylinositol 3-kinase pathway. Low dose oral sirolimus increases the risk of menstrual cycle disturbances and ovarian cysts and monitoring of sirolimus-associated ovarian toxicity is warranted and might guide clinical practice with mammalian target of rapamycin inhibitors.

Predictors of oligoamenorrhea at 1-year follow-up in premenopausal women using a levonorgestrel-releasing intrauterine system. Contraception 2007; 76:91-5. [PMID: 17656176 DOI: 10.1016/j.contraception.2007.04.003] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2007] [Revised: 03/21/2007] [Accepted: 04/14/2007] [Indexed: 10/23/2022]
Abstract
OBJECTIVE The study was conducted to identify predictors of oligoamenorrhea at 12 months in levonorgestrel-releasing intrauterine system (LNG-IUS) users. DESIGN A 12-month observational study. SETTING Gynecologic outpatient clinic in a large regional hospital in Flanders, Belgium. POPULATION OR SAMPLE A total of 150 women who had made an informed decision to use a LNG-IUS either as a method of contraception or to manage menorrhagia. METHODS All women were premenopausal and first-time users. The variables recorded prior to insertion on Days 1 to 5 of the menstrual cycle were age, parity, body mass index, indication for LNG-IUS use, prior contraceptive use, menstrual bleeding history, length of the uterine cavity, endometrial thickness, number of antral follicles, serum follicle-stimulating hormone, inhibin B and anti-Müllerian hormone. Menstrual bleeding pattern, patient satisfaction or wish to discontinue the method was noted at 3, 6 and 12 months of follow-up visits. MAIN OUTCOME MEASURES Menstrual bleeding pattern (amenorrhea, oligomenorrhea, menorrhagia) at 12 months was taken as the primary outcome measurement. Patient satisfaction was followed as a secondary outcome. RESULTS Oligoamenorrhea was associated with a high patient satisfaction. A bleeding period less than 5 days, absence of severe uterine bleeding at baseline, LNG-IUS use for contraception and oligoamenorrhea at 3 months were predictors of a favorable outcome at 12 months in a univariate analysis. The absence of severe bleeding prior to LNG-IUS insertion was the only clinically useful predictor of favorable outcome in the multivariate analysis (odds ratio 0.13, 95% confidence interval 0.02-0.66). CONCLUSIONS Patient profiling as described is not helpful in counselling women for intentional LNG-IUS use, especially not if it is planned as a method of managing menorrhagia.

Valproate is associated with new-onset oligoamenorrhea with hyperandrogenism in women with bipolar disorder. Biol Psychiatry 2006; 59:1078-86. [PMID: 16448626 DOI: 10.1016/j.biopsych.2005.10.017] [Citation(s) in RCA: 78] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2005] [Revised: 07/15/2005] [Accepted: 10/18/2005] [Indexed: 10/25/2022]
Abstract
BACKGROUND Preliminary evidence suggests that valproate is associated with isolated features of polycystic ovarian syndrome (PCOS), while contradictory data support an association between epilepsy and PCOS. The development of PCOS features after initiation of valproate was therefore examined in women with bipolar disorder using a standardized definition of PCOS. METHODS Three hundred women 18 to 45 years old with bipolar disorder were evaluated for PCOS at 16 Systematic Treatment Enhancement for Bipolar Disorder sites. A comparison was made between the incidence of hyperandrogenism (hirsutism, acne, male-pattern alopecia, elevated androgens) with oligoamenorrhea that developed while taking valproate versus other anticonvulsants (lamotrigine, topiramate, gabapentin, carbamazepine, oxcarbazepine) and lithium. Medication and menstrual cycle histories were obtained, and hyperandrogenism was assessed. RESULTS Among 230 women who could be evaluated, oligoamenorrhea with hyperandrogenism developed in 9 (10.5%) of 86 women on valproate and in 2 (1.4%) of 144 women on a nonvalproate anticonvulsant or lithium (relative risk 7.5, 95% confidence interval [CI] 1.7-34.1, p = .002). Oligoamenorrhea always began within 12 months of valproate use. CONCLUSIONS Valproate is associated with new-onset oligoamenorrhea with hyperandrogenism. Monitoring for reproductive-endocrine abnormalities is important when starting and using valproate in reproductive-aged women. Prospective studies are needed to elucidate risk factors for development of PCOS on valproate.

Abstract
The objective of this study was to evaluate the efficacy and performance, for up to 1 year, of an intrauterine system releasing 20 microg/day of levonorgestrel (LNG-IUS, Mirena) in the treatment of women with menorrhagia. It was a descriptive, prospective, non-comparative study. A 20 microg/day LNG-releasing-IUS was inserted on any day during bleeding to 44 women (between 24 and 49 years of age) who presented with menorrhagia after medical therapies had failed. Menstrual patterns were assessed, and hemoglobin concentrations were measured before LNG-IUS was inserted and at 3, 6, 9, and 12 months of use. The most common bleeding pattern at 3 months after insertion was spotting, and after 6, 9, and 12 months the majority of women presented with amenorrhea or oligomenorrhea. Three women requested removal of the LNG-IUS because of spotting, and six women expelled it spontaneously. Hemoglobin levels were improved from 102 g/L to 123 and 128 g/L at 3 and 12 months, respectively, after insertion of the LNG-IUS (p < 0.01). At 12 months 79.5% of participants continued the use of LNG-IUS. In conclusion, LNG-IUS was an effective treatment for three out of four women with menorrhagia and could be an alternative treatment for women with menorrhagia who are either contraindicated for or refuse hysterectomy or endometrial ablation.

Abstract
To investigate the association between organic solvent exposure and menstrual disturbance, we conducted a cross-sectional study among 1408 petrochemical workers in China. Based on an industrial hygiene evaluation, we classified the workshops according to the presence or absence of organic solvents (benzene, styrene, toluene, or xylene). We used logistic regression to estimate odds ratios and 95% confidence intervals for prolonged menstrual cycle length (oligomenorrhea: average cycle length > 35 days during the previous year) associated with the exposure. After adjustment for confounders, each additional year of work in an exposed workshop was associated with a 7% increase in oligomenorrhea (odds ratio, 1.07; 95% confidence interval, 1.00 to 1.14). Compared with no exposure, 3 or more years of exposure was associated with a 53% increase in oligomenorrhea (odds ratio, 1.53; 95% confidence interval, 1.00 to 2.34). We concluded that exposure to organic solvents is associated with a trend toward increased frequency of oligomenorrhea.

Abstract
BACKGROUND An exploratory, cross-sectional retrospective study was conducted to examine the effects of benzene exposure on menstrual problems. METHODS The study was based on a survey administered to over 3,000 women who worked in a large petrochemical company in Beijing, China. An abnormal menstrual cycle length (AMCL), defined as an average menstrual cycle length of greater than 35 days or less than 21 days, is the major outcome of interest. RESULTS After 7 years of benzene exposure, the adjusted odds ratio of having AMCL for each additional 5 years of exposure was 1.71 (95% CI 1.27-2.31). Feeling stressed at work was also an important predictor. CONCLUSIONS This study suggests a significant association of benzene exposure and perceived stress with menstrual disturbance. A prospective study is needed to confirm this finding.

Abstract
AIM Tamoxifen is the antihormonal treatment of choice for premenopausal breast cancer patients with advanced breast disease. Its premenopausal administration has been shown to induce supraphysiological 17beta-estradiol serum levels and to be associated with the presence of persistent, bilateral functional ovarian cysts. However, these abnormalities have not yet been compared to controls. In this study we evaluated the possibility that the above hormonal and/or ovarian abnormalities are more frequent among premenopausal breast cancer patients treated with tamoxifen than among similar nontreated patients, and thus they may be attributed to tamoxifen effect. METHODS We evaluated serum hormone levels of 17beta-estradiol, follicular-stimulating hormone, luteinizing hormone, and progesterone, the presence of ovarian cysts, and various demographic and clinical characteristics in 20 premenopausal breast cancer patients treated with tamoxifen (study group) and compared them to those observed in 12 similar nontreated patients (control group). RESULTS Ovarian cysts were found in 80% of the study patients and only in 8.3% of the control patients (P = 0.001). The incidence of oligomenorrhea was nearly significantly higher in the study than in the control group (50 and 16.7%, respectively; P = 0.0651). Various serum hormone levels tested were not found to be significantly different between the two groups, except for 17beta-estradiol serum levels as detected on days 14 and 21 of the menstrual cycle, which were significantly higher among the study than in the control patients. (Day 14 serum estradiol: 757.7 +/- 372.0 pg/mL versus 206.5 +/- 275.0 pg/mL, P = 0.0012. Day 21 serum estradiol: 300.0 +/- 134.5 pg/mL versus 96.5 +/- 71.5 pg/mL, P = 0.0008.) CONCLUSIONS Tamoxifen treatment increases the incidence of ovarian cysts and the significantly higher 17beta-estradiol serum levels in premenopausal breast cancer patients.

Abstract
To study the ovarian toxicity associated with cyclophosphamide in girls with systemic lupus erythematosus (SLE), we retrospectively reviewed the charts of 30 SLE girls aged 16 yr or younger at diagnosis, followed at three university hospitals. Gynaecological history was extracted from the charts or obtained prospectively. Ten had not received cyclophosphamide therapy, six were treated with daily oral cyclophosphamide, 10 with intravenous pulses and four with daily oral and intravenous pulses. Median oral cyclophosphamide dose was 38 g (inter-quartile range 75) and median intravenous dose 12.95 g (inter-quartile range 6.2). Six girls had oligomenorrhoea (20%) and one amenorrhoea (3%). Two treated with oral cyclophosphamide had oligomenorrhoea (33%) and one amenorrhoea (17%), two treated with both oral and intravenous pulses had oligomenorrhoea (50%), and none of those treated with intravenous pulses alone had menstrual disturbances (50% oral vs 0% intravenous pulses; P = 0.016). Girls who had menstrual disturbances had received higher doses of cyclophosphamide than those who did not (medians: 63 vs 15 g; P < 0.05). In summary, menstrual disturbances in SLE girls treated with cyclophosphamide are related to the total dose and perhaps to the administration method.

Abstract
Ninety-two women with systemic lupus erythematosus treated with oral cyclophosphamide were studied to ascertain the prevalence and the factors associated with ovarian dysfunction. Menstrual disturbance during treatment occurred in 55% of patients: 36% had amenorrhoea and 19% had oligomenorrhoea. Sustained oligomenorrhoea occurred in 12% patients. Permanent amenorrhoea (> 12 months) after cessation of oral cyclophosphamide occurred in 27% of patients. Hormonal studies in these patients were consistent with ovarian failure. Older age at initiation of treatment and high cumulative dose of cyclophosphamide were found to be associated with this outcome. There was a trend towards linear relationship between the age of initiation of cyclophosphamide therapy and frequency of amenorrhoea. A statistically significant association between amenorrhoea and cumulative dose of cyclophosphamide after adjustment for age was found whereas no such association was linked to the duration of treatment. Fourteen of the 23 women who wished to become pregnant after cessation of treatment conceived resulting in 20 live births and two abortions.

Abstract
Six stable psychiatric outpatients with hyperprolactinemia and amenorrhea/oligomenorrhea associated with their neuroleptic medications were treated with bromocriptine. Daily dosages of 5-10 mg corrected the hyperprolactinemia and restored menstruation in four of the six patients. One woman, however, developed worsened psychiatric symptoms while taking bromocriptine, and it was discontinued. Thus, three of six patients had their menstrual irregularity successfully corrected with bromocriptine. This suggests that bromocriptine should be further evaluated as potential therapy for neuroleptic-associated hyperprolactinemia and amenorrhea/galactorrhea.

Abstract
The main side effect associated with the use of Norplant contraceptive implants is a disruption of the menstrual bleeding pattern. To explore the relationship between bleeding and hormonal changes, we analyzed the estradiol (E2) and progesterone (P) patterns that preceded bleeding episodes or that corresponded to periods of amenorrhea in 103 cycles observed among 82 women using Norplant subdermal implants. Five different bleeding patterns were defined: 'normal' (24-45 day cycles), oligomenorrhea (46-90 day cycles), amenorrhea (over 90 day cycles), irregular/frequent bleeding (less than 25 day cycles), and prolonged bleeding (continuous bleeding/spotting for more than 10 days). All 'normal' cycles were associated with a rise followed by a fall in E2 levels preceding bleeding. In half of the 'normal' cycles (28/54), a rise and fall of P was also observed. The same pattern was found in oligomenorrheic cycles, but only two of 12 cycles had a rise and fall of both E2 and P. None of the subjects with amenorrhea had luteal activity. Six of the nine amenorrheic cycles displayed persistently low E2 levels (below 75 pg/ml). The remaining three had a moderate elevation in E2 levels during the sampling period. Sixty percent of the subjects who showed irregular/frequent bleeding (15/25) had low E2 levels (less than 75 pg/ml), without luteal activity, and bleeding occurred without clear evidence of a further drop in E2 levels. In the remaining 40%, bleeding was preceded by a rise and drop of E2 without luteal activity, with the exception of one women, who exhibited a rise and fall of both E2 and P. Samples were obtained in only three subjects during continuous bleeding. One had low E2 levels, and the remaining two bled continuously, in spite of having E2 levels in the normal range. We conclude that ovarian hormones continue to influence endometrial shedding during the use of Norplant contraceptive implants.

Abstract
Two young girls with epilepsy presented with menstrual disturbances whilst on treatment with sodium valproate. On withdrawing valproate therapy, period cyclicity returned to normal in both individuals. An exaggerated luteinising hormone response to parenterally administered gonadotropin-releasing hormone was present in both subjects. The temporal relationship between normalisatin of periods and stopping the sodium valproate suggests that this drug may possibly affect the control of the menstrual cycle through a GABAergic mechanism.

Abstract
We randomized 122 premenopausal women to receive tamoxifen or to undergo a surgical oophorectomy. Of 54 evaluable women treated with tamoxifen, 24% had an objective response, as compared with 21% of 53 women having an oophorectomy. The median duration of response for tamoxifen (20 months) was longer than that for surgical oophorectomy (7 months), but this did not achieve statistical significance (P = .056). Overall median survival was 15 months for 58 patients receiving tamoxifen and 25 months for 53 patients undergoing oophorectomy (P = .18). Toxicity was greater in those undergoing oophorectomy, though both treatments were well tolerated. In those premenopausal women for whom hormonal therapy is indicated, tamoxifen is a suitable alternative to surgical oophorectomy.

Abstract
In a randomized clinical study, contraceptive efficacy and bleeding patterns were studied in a group of healthy, regularly menstruating, non-lactating women (n = 84) using two 4.4 cm covered silastic rods containing levonorgestrel, Norplant(R)-2, and compared with another group of women (n = 88) using six 3.4 cm capsules also containing levonorgestrel, Norplant(R). The silastic rods or capsules were placed subdermally in the medial aspect of the upper arm. No method failure was reported up to 24 months of use in this study with either of the device. The bleeding pattern was also similar for both devices as indicated by average episode length, number of bleeding runs and number of spotting days. The continuation rates with both devices were over 80 per 100 users at the end of 12 months and over 65 per 100 users at the end of 24 months. Discontinuations due to expulsion of the device, bleeding problems or personal reasons were few and similar for both devices. The results suggest that silastic-covered rods, Norplant(R)-2, which are comparatively easier to insert and remove and have similar clinical effect, could replace capsules, Norplant(R), as a long-term reversible subdermal contraceptive.

Abstract
A Phase II multicentric study was carried out to compare the different contraceptive treatment schedules of the monthly injectable consisting of norethisterone oenanthate (NET OEN) 50 mg either given alone or in combination with estrogen esters, 2.5 or 5 mg of estradiol valerate (E2 Val.) or estradiol cypionate (E2 Cyp.). A total of 364 women were observed for 1686 months of use. Analysis of the bleeding pattern data indicated that NET OEN 50 mg when given alone gave rise to delayed cycles and/or amenorrhoea. However, the addition of estrogen esters in a dose of either 2.5 or 5 mg provided significantly better bleeding patterns. Of the different treatment schedules investigated, the combination of NET OEN 50 mg with E2 Val. 5 mg provided more consistent and better cycle control. These findings however need further validation on a larger study sample.

Abstract
Sequential examination and interview of diethylstilbestrol-exposed (DES-exposed) and -unexposed women verified that DES exposure has no effect on age at menarche and indicated no differences in the age at first coitus, pregnancy and live birth. Analysis of variance indicated that there is an age-related increase in oligomenorrhea in DES-exposed women as compared to unexposed women that disappears as the patients reach their late 20s. Prospective data collection is required to substantiate this finding. There appears to be no substantial effect of in utero exposure to DES on women's ability to conceive.

Abstract
This report summarises a survey of the management of menstrual disturbances occurring during injectable progestogen use (depot-medroxyprogesterone acetate, DMPA, and norethisterone enanthate, NET-EN) by 35 investigators from 20 countries with ongoing experience of these contraceptives. A wide range of approaches are described. The most frequently emphasised aspect of management is thorough pre-treatment counselling with further support and counselling at follow-up visits. Oestrogens in various forms are widely used for the treatment of prolonged, frequent or heavy episodes of bleeding, but nowadays are not usually used for the induction of withdrawal bleeding in women with amenorrhoea. Heavy or "severe" bleeding appears to be very uncommon and figures of 1-2% were frequently mentioned. Anecdotal information suggests that intramuscular doses or longer courses (14-21 days) of oral oestrogen, including the combined pill, are more likely to successfully stop an episode of bleeding than short courses. However, there are no hard data to show that a course of oestrogen treatment has any beneficial effect on long-term bleeding patterns. Nevertheless, temporary cessation of spotting or light bleeding may be sufficiently reassuring to the patient to ensure continued use of the method. There appears to be very little risk associated with the short-term oestrogen regimens currently used. Dilatation and curettage is almost never necessary to stop an episode of bleeding, but may occasionally be recommended for diagnostic reasons. It is clear that the bleeding disturbances associated with DMPA and NET-EN use are poorly understood and that urgent research is necessary to clarify pathophysiological mechanisms and improve management.

Abstract
Marvelon was tolerated without side effects by 338 women during 2,104 cycles. Although some errors of administration were made by patients there were no pregnancies. In contradistinction to other low dosage combination oral contraceptives this new oral contraceptive has a good control of the menstrual cycle. The incidence of clinical side effects was low. An over-suppression syndrome after the discontinuation of the treatment was not observed. Hormonal assays were done in order to investigate the difficult problems of oligomenorrhoea in adolescents with oral contraception. A marked inhibition of ovulation evident by low values of pituitary ovarian hormones was found. When the treatment was discontinued the majority of the patients showed ovulation in the first post-treatment cycle.

Abstract
An overview is presented of the major methods of contraception available to the sexually active adolescent. Emphasis is given to the combined birth control pill, while the literature describing absolute and relative contraindications to oral contraception is reviewed. It is noted that adolescents with chronic illness must also be evaluated for contraceptive needs. Other methods covered include the intrauterine device, barrier methods (diaphragm, condom, and vaginal contraceptives), injectable contraceptives, postcoital contraception, and methods under current investigation. The approach to each patient must be individualized, based on her coital activity, understanding of alternatives, medical status, and what method is chosen.

Abstract
This is an analysis of changes in menstrual cycle length and regularity occurring for a group of 211 women who had discontinued use of oral contraceptives. The analysis is based on prospectively recorded histories from the Menstruation and Reproduction History Program. Post-pill menstrual cycle length and regularity are compared with pre-pill averages. In the first post-pill cycle, there was an average increase of 6 days in cycle length. In subsequent cycles, however, cycle length and regularity were comparable to pre-pill norms in most cases.

Significance of low body weight in ovulatory dysfunction after stopping oral contraceptives. BRITISH MEDICAL JOURNAL 1976; 2:399-401. [PMID: 947444 PMCID: PMC1687484 DOI: 10.1136/bmj.2.6032.399] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 12/25/2022]
Abstract
In a group of patients who developed ovulatory dysfunction on stopping oral contraception the mean body weight of those with previosly regular cycles was significantly lower than that of women who had had ovulatory dysfunction beforeoral contraception and also that of a control group. Women of low body weight may be at particular risk of developing post-pill amenorrhoea even when there is no history pointing to ovulatory dysfunction. This should be considered when selecting a form of contraception in such women.

Abstract
Eight-seven cases of secondary amenorrhoea of more than 6 months' duration developing after treatment with oral contraceptives (group I) were compared with 227 cases of secondary amenorrhoea not preceded by treatment with combined tablets (group II). The two groups were collected during the same period. The average age of the patients was 4 years higher in group I than in group II. Oligomenorrhoea and previously occurred in 30% of group I and in 46% of group II. Pronounced predisposing factors., such as psychogenic trauma and stress with or without considerable change in body weight, were encountered in 26% in group I and 56% in group II. The incidence of increased urinary output of 17-keto steroids, 17-ketogenic steroids and of hirsutism was slightly higher in group II. The percentage of eosinophilic cells in vaginal scrapings was low in 20% in group I as compared with 46% in group II. Spontaneous return of pituitary-ovarian function occurred in 40% in both groups. Patients recovering spontaneously in group I presented a maximum during the first few months, followed by a steady and fairly uniform decline. Spontaneous recovery in group II was more or less independent of time. It seems reasonable to believe that oral contraceptives did promote or contribute to the development of secondary amenorrhoea in about 50%, representing cases with various predisposing factors. A causal relation between oral contraceptives and secondary amenorrhoea was indicated in the remaining 50% because of perfectly normal ovarian function before treatment and absence of predisposing factors.
