Abstract
Introduction: Which is optimal to treat clomiphene citrate-resistant polycystic ovary syndrome (CCR-PCOS) with LOD or metformin remains a problem. There are three inconsistent or even contradictory views.Objectives: The present meta-analysis aimed to evaluate the effectiveness and safety of Metformin with or without CC and to compare them with LOD with or without CC (Met/Met-CC vs. LOD/LOD-CC) in women with CCR-PCOS who also have anovulation.Data source: The PubMed, Cochrane, and Embase databases were searched to identify relevant studies reported between 1 Jan 1966 and 31 Aug 2019; the search was updated on 17 May 2022.Study eligibility criteria: We included randomized controlled trials (RCTs) of CCR-PCOS that had considered Met/Met-CC and LOD/LOD-CC as the exposure variables and fertility as the main outcome variable.Study appraisal and synthesis methods: We assessed study quality using the Cochrane risk-of-bias tool. The primary effectiveness outcome was live birth/ongoing pregnancy rate and the primary safety outcome was miscarriage rate. A fixed-effect meta-analysis was performed. The robustness of the results was assessed using sensitivity analyses. Meta-regression and subgroup analysis were performed to examine the reasons for heterogeneity. Publication bias was examined using the funnel plot, Egger linear regression, and Begg rank correlation tests. The quality of this meta-analysis was estimated according to the GRADE approach. This meta-analysis has been registered in PROSPERO (CRD42021240156).Results: Among 71 potentially relevant studies, we included five RCTs in our meta-analysis. We found no difference in effectiveness between Met-CC and LOD in terms of live birth/ongoing pregnancy (RR = 1.02, 95% CI: 0.87–1.21, z = 0.28; p = 0.780), and miscarriage rates (RR = 0.79, 95% CI: 0.46–1.36, z = 0.86; p = 0.390). I2 tests results revealed moderate or no heterogeneity (I2 = 51.4%, p = 0.083; I2= 0.0%; p = 0.952). Sensitivity analysis confirmed the robustness of the results. Funnel plot, Egger linear regression, and Begg rank correlation tests implied no publication bias (p > 0.05). LOD was more expensive than Met (€1050 vs. €50.16). The evidence quality was moderate.Conclusion: There is no evidence on the difference in the outcomes between the two interventions regarding ovulation, pregnancy, and live birth. As LOD is an invasive procedure and carries inherent risks, the use of Met/Met-CC should be the second-line treatment for women with CCR-PCOS.Systematic Review Registration: identifier CRD42021240156.

Abstract
PURPOSE To determine the contributing factor in infertility treatment with laparoscopic ovarian drilling (LOD) to the decrease in serum anti-Müllerian hormone (AMH) levels in patients with polycystic ovarian syndrome using an ultrasonically activated device. METHODS A retrospective analysis was performed in 60 patients (aged 23-36 years) who received 25-120 punctures in each ovary with LOD treatment from January 2014 to December 2018. RESULTS The mean decrease in serum AMH level per puncture with LOD was 0.07 ± 0.04 ng/ml in all 60 patients and 0.08 ± 0.04 ng/ml in patients with ≥10 ng/ml preoperative serum AMH level, which was significantly higher than in those with <10 ng/ml (0.05 ± 0.02 ng/ml). The mean decrease in serum AMH level per puncture in patients with body mass index (BMI) < 18.5 kg/m2 (0.10 ± 0.03 ng/ml) was significantly higher than in those with BMI 18.5-25 kg/m2 (0.07 ± 0.04 ng/ml) and >25 kg/m2 (0.06 ± 0.02 ng/ml). CONCLUSIONS The mean decrease in serum AMH levels per puncture with LOD using an ultrasonically activated device depends on the preoperative serum AMH level and BMI of patients.

Abstract
Abstract
Background
The main objective of this randomized controlled trial was to study the impact of LOD on the pregnancy rate after ICSI-ET in PCOS.
Results
The study was conducted in Egypt in the period 2015–2017 and included 212 clomiphene-resistant PCOS patients, with at least 1-year infertility. The study group was the drilling group who underwent LOD and then ICSI-ET, while the control group did not undergo LOD but directly proceeded to ICSI-ET. The primary outcome was the clinical pregnancy rate per ET cycle. The baseline characteristics and hormonal profiles were comparable (p > 0.05) between the two groups. Ovarian stimulation days were (p < 0.001) higher in the drilling group. Endometrial thickness, estradiol at triggering day, and the number of oocytes retrieved were (p < 0.001) lower in the drilling group. The numbers of embryos transferred were not different (p > 0.05). The clinical pregnancy rate per ET cycle was higher in the drilling group (51%) than in the control group (37%) (p = 0.046). Multiple pregnancies were not significantly (p = 0.265) different between groups. The rate of OHSS was (p = 0.046) higher in the control group. Coasting was (p < 0.001) higher in the control group (18%) compared to the drilling group (2%).
Conclusion
Laparoscopic ovarian drilling for PCOS patients before ICSI-ET improves the clinical pregnancy rate with a reduction of OHSS.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a common condition affecting 8% to 13% of reproductive-aged women. In the past clomiphene citrate (CC) used to be the first-line treatment in women with PCOS. Ovulation induction with letrozole should be the first-line treatment according to new guidelines, but the use of letrozole is off-label. Consequently, CC is still commonly used. Approximately 20% of women on CC do not ovulate. Women who are CC-resistant can be treated with gonadotrophins or other medical ovulation-induction agents. These medications are not always successful, can be time-consuming and can cause adverse events like multiple pregnancies and cycle cancellation due to an excessive response. Laparoscopic ovarian drilling (LOD) is a surgical alternative to medical treatment. There are risks associated with surgery, such as complications from anaesthesia, infection, and adhesions. OBJECTIVES To evaluate the effectiveness and safety of LOD with or without medical ovulation induction compared with medical ovulation induction alone for women with anovulatory polycystic PCOS and CC-resistance. SEARCH METHODS We searched the Cochrane Gynaecology and Fertility Group (CGFG) trials register, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL and two trials registers up to 8 October 2019, together with reference checking and contact with study authors and experts in the field to identify additional studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) of women with anovulatory PCOS and CC resistance who underwent LOD with or without medical ovulation induction versus medical ovulation induction alone, LOD with assisted reproductive technologies (ART) versus ART, LOD with second-look laparoscopy versus expectant management, or different techniques of LOD. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, assessed risks of bias, extracted data and evaluated the quality of the evidence using the GRADE method. The primary effectiveness outcome was live birth and the primary safety outcome was multiple pregnancy. Pregnancy, miscarriage, ovarian hyperstimulation syndrome (OHSS), ovulation, costs, and quality of life were secondary outcomes. MAIN RESULTS This updated review includes 38 trials (3326 women). The evidence was very low- to moderate-quality; the main limitations were due to poor reporting of study methods, with downgrading for risks of bias (randomisation and allocation concealment) and lack of blinding. Laparoscopic ovarian drilling with or without medical ovulation induction versus medical ovulation induction alone Pooled results suggest LOD may decrease live birth slightly when compared with medical ovulation induction alone (odds ratio (OR) 0.71, 95% confidence interval (CI) 0.54 to 0.92; 9 studies, 1015 women; I2 = 0%; low-quality evidence). The evidence suggest that if the chance of live birth following medical ovulation induction alone is 42%, the chance following LOD would be between 28% and 40%. The sensitivity analysis restricted to only RCTs with low risk of selection bias suggested there is uncertainty whether there is a difference between the treatments (OR 0.90, 95% CI 0.59 to 1.36; 4 studies, 415 women; I2 = 0%, low-quality evidence). LOD probably reduces multiple pregnancy rates (Peto OR 0.34, 95% CI 0.18 to 0.66; 14 studies, 1161 women; I2 = 2%; moderate-quality evidence). This suggests that if we assume the risk of multiple pregnancy following medical ovulation induction is 5.0%, the risk following LOD would be between 0.9% and 3.4%. Restricting to RCTs that followed women for six months after LOD and six cycles of ovulation induction only, the results for live birth were consistent with the main analysis. There may be little or no difference between the treatments for the likelihood of a clinical pregnancy (OR 0.86, 95% CI 0.72 to 1.03; 21 studies, 2016 women; I2 = 19%; low-quality evidence). There is uncertainty about the effect of LOD compared with ovulation induction alone on miscarriage (OR 1.11, 95% CI 0.78 to 1.59; 19 studies, 1909 women; I2 = 0%; low-quality evidence). OHSS was a very rare event. LOD may reduce OHSS (Peto OR 0.25, 95% CI 0.07 to 0.91; 8 studies, 722 women; I2 = 0%; low-quality evidence). Unilateral LOD versus bilateral LOD Due to the small sample size, the quality of evidence is insufficient to justify a conclusion on live birth (OR 0.83, 95% CI 0.24 to 2.78; 1 study, 44 women; very low-quality evidence). There were no data available on multiple pregnancy. The likelihood of a clinical pregnancy is uncertain between the treatments, due to the quality of the evidence and the large heterogeneity between the studies (OR 0.57, 95% CI 0.39 to 0.84; 7 studies, 470 women; I2 = 60%, very low-quality evidence). Due to the small sample size, the quality of evidence is not sufficient to justify a conclusion on miscarriage (OR 1.02, 95% CI 0.31 to 3.33; 2 studies, 131 women; I2 = 0%; very low-quality evidence). Other comparisons Due to lack of evidence and very low-quality data there is uncertainty whether there is a difference for any of the following comparisons: LOD with IVF versus IVF, LOD with second-look laparoscopy versus expectant management, monopolar versus bipolar LOD, and adjusted thermal dose versus fixed thermal dose. AUTHORS' CONCLUSIONS Laparoscopic ovarian drilling with and without medical ovulation induction may decrease the live birth rate in women with anovulatory PCOS and CC resistance compared with medical ovulation induction alone. But the sensitivity analysis restricted to only RCTs at low risk of selection bias suggests there is uncertainty whether there is a difference between the treatments, due to uncertainty around the estimate. Moderate-quality evidence shows that LOD probably reduces the number of multiple pregnancy. Low-quality evidence suggests that there may be little or no difference between the treatments for the likelihood of a clinical pregnancy, and there is uncertainty about the effect of LOD compared with ovulation induction alone on miscarriage. LOD may result in less OHSS. The quality of evidence is insufficient to justify a conclusion on live birth, clinical pregnancy or miscarriage rate for the analysis of unilateral LOD versus bilateral LOD. There were no data available on multiple pregnancy.

Abstract
Objective. To review the benefits and harms of N-acetylcysteine (NAC) in women with polycystic ovary syndrome (PCOS). Method. Literature search was conducted using the bibliographic databases, MEDLINE (Ovid), CINAHL, EMBASE, Scopus, PsyInfo, and PROQUEST (from inception to September 2013) for the studies on women with PCOS receiving NAC. Results. Eight studies with a total of 910 women with PCOS were randomized to NAC or other treatments/placebo. There were high risk of selection, performance, and attrition bias in two studies and high risk of reporting bias in four studies. Women with NAC had higher odds of having a live birth, getting pregnant, and ovulation as compared to placebo. However, women with NAC were less likely to have pregnancy or ovulation as compared to metformin. There was no significant difference in rates of the miscarriage, menstrual regulation, acne, hirsutism, and adverse events, or change in body mass index, testosterone, and insulin levels with NAC as compared to placebo. Conclusions. NAC showed significant improvement in pregnancy and ovulation rate as compared to placebo. The findings need further confirmation in well-designed randomized controlled trials to examine clinical outcomes such as live birth rate in longer follow-up periods. Systematic review registration number is CRD42012001902.

Abstract
BACKGROUND Infertility is defined as inability of couple to conceive after one year of unprotected intercourse. The prevalence of infertility in Pakistan is 21.9%. The most common cause of medically treatable infertility is polycystic ovarian syndrome (PCO). This study was conducted to see the frequency and outcome of treatment in PCOs related infertility in infertile couples coming to Mohammad Medical College Hospital, Mirpurkhas, Sindh. METHODS This prospective observational study was conducted at Muhammad Medical College for three years from 2005 to 2008. Total 1289 infertile couples were included in this study. RESULT The frequency of PCOs in female related infertility was 38.5%. Other causes of female infertility were in the frequency of 44% pelvic inflammatory disease, 12.3% endometriosis, 2.9% hyperprolactenemia, and 1.35% hypothyroidism. Patients with PCOS were given different treatment modalities. One hundred fifty patients with PCO were given ovulation induction with clomephene citrate and out of them 109 (72%) conceived. Sixty three women were given combination of clomephene citrate and Metformin. Out of them 50 (79%) conceived. Five patients were given gonadotrophins, Out of them 2 (40%) patients conceived. Five patients had laparoscopic drilling out of them 3 (60%) conceived. CONCLUSION In contrast to the literature review Polycystic Ovarian Syndrome turned out to be the second most common cause of female related infertility. But as the international literature shows it had very good out come after medical and /or surgical treatment.

Abstract
Polycystic ovaries syndrome (PCOS) is one of the most common female hormonal disorders. Its multiple components--reproductive, metabolic, neoplasic and cardiovascular--have a major impact on the public health. Androgen excess and resistance to insulin, probably from genetic origin, are responsible for most of the clinical symptomatology. Resistance to insulin seems to be accompanied by a greater risk of glucose intolerance, type 2 diabetes, lipidic anomalies and can involve the development of cardiovascular diseases. In addition, sleep apnea syndrome is more progressively described in PCOS. Infertility, menses disorders and hirsutism often push these patients to consult their physician. A better understanding of the physiopathological mechanisms led to the emergence of new therapeutic options increasing the sensitivity to insulin. Besides the pregnancy wishes, cares aim to attenuate the marks of the hyper-androgenism (hormonal treatment and cosmetic) and to correct cardiovascular, respiratory and gynaecological risk factors. In case of infertility by anovulation, cares must be performed by trained experts to minimize the risk of ovarian hyper-stimulation syndrome and multiple pregnancies. A gradation from loose weight to clomiphene citrate ovulation induction, ovarian drilling, low dose gonadotropin, in vitro fertilisation, or in vitro maturation of oocytes should bring back good reproduction potential.

Abstract
OBJECTIVE To describe the first reported cases of two women with polycystic ovary syndrome (PCOS) desirous of pregnancy who conceived trichorionic pregnancies following ovulation induction with metformin alone and metformin plus clomiphene. DESIGN Case report. SETTING Private fertility practice. PATIENT(S) Two women with polycystic ovary syndrome, one lean and one overweight, both oligoovulatory and not undertaking their first cycle of treatment. INTERVENTION(S) Ovulation induction by metformin alone or in combination with clomiphene MAIN OUTCOME MEASURE(S) Higher-order multiple pregnancy (triplet or greater). RESULT(S) Two cases of trichorionic pregnancy. CONCLUSION(S) This is the first report of higher-order multiple pregnancies resulting from the use of either metformin alone or in combination with clomiphene. The additive effects of adjunctive treatments such as weight reduction, ovarian drilling, and clomiphene and metformin therapy may result in an increased incidence of higher-order multiple pregnancy and women need to be counseled about this risk. Further research is required to quantify the risk of this event per treatment cycle.

Abstract
BACKGROUND Women with polycystic ovarian syndrome (PCOS) commonly consult endocrinologists or gynaecologists and it is not known whether these specialty groups differ in their approach to management. OBJECTIVE To compare the investigation, diagnosis and treatment practices of endocrinologists and gynaecologists who treat PCOS. DESIGN AND SETTING A mailed questionnaire containing a hypothetical patient's case history with varying presentations--oligomenorrhoea, hirsutism, infertility and obesity--was sent to Australian clinical endocrinologists and gynaecologists in teaching hospitals and private practice. RESULTS Evaluable responses were obtained from 138 endocrinologists and 172 gynaecologists. The two specialty groups differed in their choice of essential diagnostic criteria and investigations. Endocrinologists regarded androgenization (81%) and menstrual irregularity (70%) as essential diagnostic criteria, whereas gynaecologists required polycystic ovaries (61%), androgenization (59%), menstrual irregularity (47%) and an elevated LH/FSH ratio (47%) (all P-values < 0.001). In investigation, gynaecologists were more likely to request ovarian ultrasound (91%vs. 44%, P < 0.001) and endocrinologists more likely to measure adrenal androgens (80%vs. 58%, P < 0.001) and lipids (67%vs. 34%, P < 0.001). Gynaecologists were less likely to assess glucose homeostasis but more likely to use a glucose tolerance test to do so. Diet and exercise were chosen by most respondents as first-line treatment for all presentations. However, endocrinologists were more likely to use insulin sensitizers, particularly metformin, for these indications. In particular, for infertility, endocrinologists favoured metformin treatment whereas gynaecologists recommended clomiphene. CONCLUSIONS There is a lack of consensus between endocrinologists and gynaecologists in the definition, diagnosis and treatment of PCOS. As a consequence, women may receive a different diagnosis or treatment depending on the type of specialist consulted.

Abstract
BACKGROUND Infertility due to anovulation is a common problem in women. The first line oral treatment is with anti-oestrogens, such as clomiphene citrate. Unfortunately there may be resistance and alternative and adjunctive treatments have been developed. These include tamoxifen, dexamethasone, bromocriptine and aromatase inhibitors (AIs). OBJECTIVES To determine the relative effectiveness of anti-oestrogen agents, with or without medical adjuncts, in women with WHO group 2 anovulation. SEARCH STRATEGY We searched the Cochrane Menstrual Disorders and Subfertility Group trial register (searched 5th July 2004), CENTRAL (The Cochrane Library Issue 2 2004), MEDLINE (1966 to June 2004) and EMBASE (1980 to June 2004) for identification of relevant randomised controlled trials (RCTs). Additionally the United Kingdom National Institute for Clinical Excellence (NICE) guidelines and the references of relevant reviews and RCTs were searched. SELECTION CRITERIA RCTs that compare oral anti-oestrogen agents for ovulation induction (alone or in conjunction with medical adjuncts) in anovulatory subfertility, were considered for inclusion in the review. Metformin and other insulin sensitizing agents were not included. Hyperprolactinaemic infertility was not included. DATA COLLECTION AND ANALYSIS Data extraction and quality assessment was done independently by two reviewers. The primary outcome was live birth, secondary outcomes were: pregnancy, ovulation, miscarriage, multiple pregnancy, overstimulation, ovarian hyperstimulation syndrome and patient reported adverse effects. MAIN RESULTS Twelve RCTs were found and included in this review. No trials reported live birth as an outcome. Miscarriage and multiple pregnancy rates were poorly reported. Clomiphene was shown to be effective in increasing pregnancy rate when compared to placebo (fixed OR 5.8, 95% CI 1.6 to 21.5; NNT 5.9, 95% CI 3.6 to 16.7). No evidence of a difference in effect was found between clomiphene and tamoxifen (fixed OR 1.0, 95% CI 0.5 to 2.1). The use of clomiphene in combination with tamoxifen did not find any evidence of effect on pregnancy rate when compared to clomiphene alone (fixed OR 3.3, 95% CI 0.1 to 91.6). The comparison between two AIs (letrozole and anastrozole) did not find any evidence of a difference in effect on pregnancy rate (fixed OR 1.9, 95% CI 0.4 to 8.9). For the intervention of clomiphene plus ketoconazole vs clomiphene no evidence of a difference in effect for pregnancy rate was found (fixed OR 2.4, 95% CI 0.9 to 6.4). For clomiphene plus bromocriptine vs clomiphene no evidence of a difference in effect on pregnancy rate was found (fixed OR 1.0, 95% CI 0.3 to 3.0) rates. However, clomiphene plus dexamethasone treatment resulted in a significant improvement in the pregnancy rate (fixed OR 11.3, 95% CI 5.3 to 24.0; NNT 2.7, 95% CI 2.1 to 3.6) when compared to clomiphene alone as did clomiphene plus pretreatment with combined oral contraceptives (fixed OR 27.2, 95% CI 3.1 to 235.0; NNT 2.0, 95% CI 1.4 to 3.4). AUTHORS' CONCLUSIONS This review shows evidence supporting the effectiveness of the current first line treatment, clomiphene citrate. No evidence of a difference in effect was found between clomiphene and tamoxifen. The use of dexamethasone as an adjunct to clomiphene therapy appears promising as do combined oral contraceptives. This review has highlighted a gap in the literature on effects of these drugs on outcomes such as miscarriage rate. Evidence in favour of these interventions is flawed. RCTs of adequate power and of high methodological quality are required for the older treatments such as clomiphene, alone and with medical adjuncts, and also for the newer drugs such as the AIs.

Abstract
BACKGROUND Ovulation induction with gonadotrophins is the standard treatment strategy for women with clomiphene citrate (CC)-resistant polycystic ovary syndrome (PCOS). Laparoscopic electrocautery of the ovaries is an alternative treatment modality, leading to a comparable cumulative pregnancy rate. In deciding which treatment to opt for, women's health-related quality of life (HRQoL) should be taken into account. METHODS A total of 168 CC-resistant women with PCOS were randomly assigned to receive either the electrocautery strategy, entailing laparoscopic electrocautery of the ovaries followed by CC and recombinant FSH (rFSH) if anovulation persisted, or ovulation induction with rFSH. We assessed women's HRQoL with the standard questionnaires Short Form-36, Rotterdam Symptom Checklist and Center for Epidemiological Studies Depression Scale, administered before randomization and 2, 12 and 24 weeks thereafter. RESULTS The intention to treat analysis revealed no significant differences between the treatment groups on any of the scales at any point during follow-up. In women without an ongoing pregnancy, those treated with rFSH showed significantly more depressive symptoms than women allocated to the electrocautery strategy, with or without CC, although differences were small. CONCLUSIONS Overall, HRQoL was not affected in both groups. In women still under treatment, rFSH was slightly more burdensome for women's HRQoL than electrocautery with or without CC.

Abstract
BACKGROUND This paper is a systematic review of metformin versus clomiphene citrate (CC) in women with polycystic ovary syndrome (PCOS). METHODS Meta-analysis Of Observational Studies in Epidemiology (MOOSE) and QUality Of Reporting Of Meta-analyses (QUOROM) guidelines were followed. A systematic computerized literature search was done of seven bibliographic databases. Inclusion criteria included cohort and randomized controlled trials (RCT) of women with PCOS and the following medications: metformin versus placebo; metformin versus CC; metformin plus CC versus placebo plus CC. Rev-man 4.1 and Metaview 4.0 were used to analyse data. Relative risk (RR) estimates were presented. A chi2-test determined the significance of the association. Heterogeneity was determined by the Cochran Q-test. RESULTS Metformin was 50% better than placebo for ovulation induction in infertile PCOS patients [RR 1.50; 95% confidence interval (CI) 1.13, 1.99]. Metformin was also of benefit in non-infertile (i.e. patients with PCOS who were not complaining of infertility) PCOS patients for cycle regulation compared to placebo (RR 1.45; CI 1.11, 1.90). Metformin was not of confirmed benefit versus placebo for achievement of pregnancy (RR 1.07; CI 0.20, 5.74). Metformin plus CC may be 3-4-fold superior to CC alone for ovulation induction (RR 3.04; CI 1.77, 5.24) and pregnancy (RR 3.65; CI 1.11, 11.99) in women with PCOS. CONCLUSIONS Metformin is effective for ovulation induction and cycle regulation in this group of patients. Metformin plus CC appears to be very effective for achievement of pregnancy compared to CC alone. No RCTs directly compare metformin to CC but the need for such a trial exists.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most common endocrine diseases affecting women of fertile age, and is characterized by hyperandrogenism, chronic anovulatory cycles and oligomenorrhea or amenorrhea. Given the repercussions of chronic anovulation on sterility, PCOS is a heavy social burden. Here we describe the procedures used to induce ovulation in PCOS patients, the surgical approach and medical treatments that are still being experimented.

Abstract
Laparoscopic ovarian drilling is a relatively simple procedure performed by minimal access and usually on an outpatient basis. It provides an alternative treatment option for polycystic ovary syndrome (PCOS) patients anovulatory to clomiphene citrate. The mechanism of action of laparoscopic ovarian drilling is unclear; its beneficial effect is apparently due to destruction of the androgen-producing stroma. The procedure appears to have little or no effect on insulin sensitivity and lipoprotein profile. The majority (56-94%) of PCOS patients who are clomiphene citrate resistant ovulate after drilling, and at least half of them go on to achieve a pregnancy. Predictive factors for pregnancy are younger age and lower body mass index. The endocrine changes resulting from ovarian drilling last for an extended period of time. Exogenous gonadotrophin treatment and laparoscopic ovarian drilling appear to yield comparable ovulation and pregnancy rates; however, multiple pregnancy is rare with drilling. There are several complications associated with the procedure, including post-operative periadnexal adhesion formation. Alternative treatment options, including lifestyle modification (diet and exercise) and metformin, may well reduce the need for ovarian drilling in well-selected cases. Progress in understanding of this complex syndrome and effective new treatments will further diminish the need for surgery.

Abstract
Hirsutism, which is a common clinical problem in women of reproductive age, is characterized by excessive growth of terminal hair in the androgen-sensitive skin regions. It is the result of either androgen excess or increased sensitivity of the hair follicles to normal levels of androgens. The management, which includes cosmetic measures and medical treatment, is far from satisfactory. Anti-androgen drugs play a key role in the treatment of hirsutism, but they have some side-effects which may result in cessation of the drug. On the other hand, anti-androgen treatment often needs to be continued for a long time. So, safe, inexpensive, and effective anti-androgen drugs are needed. Recently low-dose anti-androgen drugs have been shown to be effective in the maintenance of treatment. On the other hand, cyproterone acetate plus ethyniloestradiol and spironolactone, cyproterone acetate plus ethyniloestradiol and finasteride, and spironolactone and finasteride combinations have been used successfully in decreasing the hirsutism score. There are also some promising data regarding the effects of insulin sensitizers in the treatment of hirsutism, particularly in patients with polycystic ovarian syndrome. In the present review, the main features of anti-androgen drugs, new combined treatments, and insulin sensitizers in the treatment of hirsutism are discussed.

Abstract
BACKGROUND In normal menstrual cycles, gonadotrophin releasing hormone (GnRH) secretion is pulsatile, with intervals of 60-120 minutes in the follicular phase. Treatment with pulsatile GnRH infusion by the intravenous or subcutaneous route using a portable pump has been used successfully in patients with hypogonadotrophic hypogonadism. Assuming that the results would be similar in women with polycystic ovary syndrome (PCOS), pulsatile GnRH has been used to induce ovulation in these women. Although ovulation and pregnancy have been achieved, the effectiveness of pulsatile GnRH in women with PCOS has not been clearly demonstrated. OBJECTIVES To assess the effectiveness of pulsatile GnRH administration in women with polycystic ovary syndrome (PCOS), in terms of ongoing pregnancy, ovulation, clinical pregnancy, ovarian hyperstimulation syndrome (OHSS), multiple pregnancy, miscarriage, and multifollicular growth. SEARCH STRATEGY We searched the Cochrane Menstrual Disorders & Subfertility Group trials register (searched 13 August 2003), the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library Issue 2, August 2001), MEDLINE (January 1966 to August 2003), EMBASE (January 1985 to August 2003) and reference lists of articles. We also contacted manufacturers and researchers in the field. SELECTION CRITERIA All relevant published randomised clinical trials were selected for inclusion if treatment consisted of pulsatile GnRH administration versus another treatment for ovulation induction in subfertile women with PCOS. DATA COLLECTION AND ANALYSIS Relevant data were extracted independently by two reviewers (NB, MW). Validity was assessed in terms of method of randomisation, completeness of follow-up, presence or absence of crossover and co-intervention. All trials were screened and analysed for predetermined quality criteria. DATA SYNTHESIS 2X2 tables were generated for all the relevant outcomes. Odds ratios were generated using the Peto method. MAIN RESULTS Four randomised clinical trials involving 57 women were identified comparing four different treatments: GnRH versus HMG, GnRH and FSH versus FSH, GnRH following pretreatment with GnRH agonist (GnRHa) versus GnRH only, GnRH following pretreatment with GnRHa versus clomiphene citrate. This means that there was only one trial in any one comparison. In two studies, data of pre- and post-crossover were not described separately. All trials were small and of too short duration to show any significant differences in pregnancy results. The odds ratio for ongoing pregnancy, only described in one trial, was 7.5 (95% CI 0.44 to 127) in the comparison GnRH following pretreatment with GnRHa versus GnRH only in favour of the first group. Multiple pregnancies were not seen. Ovarian hyperstimulation syndrome was seen only in women allocated to ovulation induction with HMG. REVIEWER'S CONCLUSIONS The four trials describing four different comparisons with a short follow up (1 to 3 cycles) were too small to either prove or discard the value of pulsatile GnRH treatment in patients with polycystic ovary syndrome.

Abstract
Polycystic ovary syndrome [PCOS] is the commonest cause of anovulatory infertility. Treatment modes available are numerous mainly relying on ovarian stimulation with FSH, a reduction in insulin concentrations and a decrease in LH levels as the basis of the therapeutic principles. Clomiphene citrate is still the first line treatment and if unsuccessful is usually followed by direct FSH stimulation. This should be given in a low dose protocol, essential to avoid the otherwise prevalent complications of ovarian hyperstimulation syndrome and multiple pregnancies. The addition of a GnRH agonists, while very useful during IVF/ET, adds little to ovulation induction success whereas the position of GnRH antagonists is not yet clear. Hyperinsulinemia is the commonest contributor to the state of anovulation and its reduction, by weight loss or insulin sensitizing agents such as metformin, will alone often restore ovulation or will improve results when used in combination with other agents. Laparoscopic ovarian drilling is proving equally as successful as FSH for the induction of ovulation, particularly in thin patients with high LH concentrations. Aromatase inhibitors are presently being examined and may replace clomiphene in the future. When all else has failed, IVF/ET produces excellent results. In conclusion, there are very few women suffering from anovulatory infertility associated with PCOS who cannot be successfully treated today.

Abstract
OBJECTIVE To evaluate the role of laparoscopic ovarian drilling and treatment with metformin in the management of the polycystic ovary syndrome (PCOS). DESIGN A literature search was conducted using the keywords laparoscopy, laparoscopic ovarian drilling, laparoscopic ovarian diathermy, PCOS, metformin, and ovulation. The MEDLINE and EMBASE databases and the Cochrane Database of Systematic Reviews were searched. RESULTS No randomized comparisons have been done between laparoscopic ovarian drilling and metformin therapy. However, the ovulation and pregnancy rates appear to be similar for both techniques. Both treatments decrease the incidence of ovarian hyperstimulation and the cancellation rate of IVF cycles. However, unlike laparoscopic ovarian drilling, metformin may decrease the incidence of type 2 diabetes and coronary heart disease. CONCLUSION(S) Given the similar magnitude of the results without the potential risks and complication of surgery, we propose that laparoscopic ovarian drilling should be used sparingly in favor of less invasive treatment with metformin.

Abstract
OBJECTIVE To assess the effectiveness of a second laparoscopic ovarian diathermy (LOD) in women with polycystic ovary syndrome (PCOS). DESIGN Retrospective study. SETTING Tertiary infertility clinic. PATIENT(S) Twenty anovulatory infertile women with PCOS who underwent LOD 1-6 years previously. Twelve subjects had previously responded positively to the first LOD, but the anovulatory status recurred (Group I), whereas eight subjects had not responded at all (Group II). INTERVENTION(S) Laparoscopic ovarian diathermy. MAIN OUTCOME MEASURE(S) Rates of ovulation, pregnancy and resumption of menstrual regularity, and biochemical changes. RESULT(S) An overall ovulation rate of 12 out of 20 women (60%) and a pregnancy rate of 10 out of 19 (53%) were achieved after the second LOD. In women (n = 12) who previously responded positively to the first LOD (LOD-sensitive), the ovulation and pregnancy rates were 10 out of 12 (83%) and 8 out of 12 women (67%), respectively, which were significantly (P<.05) higher than 2 out of 8 (25%) and 2 out of 7 (29%) of the previous nonresponders (LOD-resistant). Statistically significant hormonal changes including reduction of luteinizing hormone (LH), testosterone (T), and free androgen index (FAI) after the repeat LOD were only observed in the LOD-sensitive group. CONCLUSION(S) Repeat LOD is highly effective in women who previously responded to the first procedure.

Abstract
OBJECTIVE To compare the effectiveness of laparoscopic ovarian diathermy with gonadotropin ovulation induction for women with clomiphene citrate-resistant polycystic ovary syndrome. DESIGN Randomized controlled trial. SETTING A tertiary referral fertility clinic. PATIENT(S) Women with anovulatory infertility secondary to clomiphene-resistant polycystic ovary syndrome. Inclusion criteria were age of <39 years, body mass index of <35 kg/m(2), failure to ovulate with 150 mg of clomiphene citrate for 5 days in the early follicular phase, >12 months of infertility, and no other causes of infertility. INTERVENTION(S) Laparoscopic ovarian diathermy versus three cycles of urinary or recombinant gonadotropins. MAIN OUTCOME MEASURE(S) Cumulative pregnancy and miscarriage rates. RESULT(S) Cumulative pregnancy rates were 28% at 6 months for laparoscopic ovarian diathermy and 33% for three cycles of ovulation induction with gonadotropins. There were three miscarriages in each group. Women in the laparoscopic ovarian diathermy arm of the study had four additional spontaneous pregnancies 6 to 12 months after surgery. CONCLUSION(S) There was no statistically significant difference in pregnancy or miscarriage rates during the 6-month follow-up period or the three cycles. Laparoscopic ovarian diathermy is a safe and effective alternative to ovulation induction with gonadotropins.

Abstract
Hyperandrogenaemia in women presents in a variety of ways, including problems with the reproductive system. The commonest cause is polycystic ovary syndrome (PCOS), a condition found in 5-10% of all women. PCOS has origins that are genetic and environmental but the end organ, the ovary, exhibits excessive androgen production with enhanced sensitivity to luteinising hormone and insulin. Interventions include approaches that target both these hormones as well as the ovary itself.
