Abstract
Utilization of anti-obesity agents is rising in reproductive-age females with some planning for future pregnancy. Lifestyle-induced weight loss has been shown to increase spontaneous conception rate, improve rates of fertility intervention complications, and decrease pregnancy comorbidities. However, the definitive role of assisting weight loss with medication prior to pregnancy remains to be established. The implications of anti-obesity agent used prior to pregnancy are explored in this narrative review, considering benefits of weight loss as well as available evidence for use and risks of anti-obesity agents prior to pregnancy.

Abstract
Polycystic ovarian syndrome (PCOS) is considered the most common endocrine disorder affecting females in today's world. Although it has been primarily studied and discussed in terms of its reproductive symptoms such as infertility, amenorrhea or oligomenorrhea, acne, hirsutism, and mood disorders, there is yet another unexplored and under-diagnosed category in the PCOS spectrum of diseases: its cardio-metabolic consequences. PCOS patients are prone to these abnormalities from a very young age, increasing their morbidity and mortality rates compared to their regular counterparts. The usual pathogenesis of PCOS is a culmination of several genetic and environmental factors. Regarding its cardio-metabolic aspects, insulin resistance (IR) is said to be the single most important cause of a variety of metabolic risk factors, including type 2 diabetes mellitus (T2DM), metabolic syndrome (MetS), dyslipidemia, obesity, and hypertension (HTN), whereas a few other non-traditional factors such as C-reactive protein (CRP), carotid intima-media thickness (IMT), coronary artery calcification (CAC), and endothelial dysfunction are also said to be increased in PCOS patients, further increasing their risk of complications due to cardiovascular diseases (CVD). A timely diagnosis and adequate treatment of these risk factors by using lifestyle interventions, diet, and/or medications are essential to reduce the burden of PCOS in today's world. This article has highlighted an array of traditional and non-traditional cardio-metabolic consequences PCOS patients are prone to and their systematic pathogenesis. In addition, an outline of recommendations has been given in the pharmacological and non-pharmacological sections of this article, which may benefit doctors in managing this challenging condition.

Abstract
BACKGROUND Women with polycystic ovary syndrome (PCOS) are almost three times more likely to be obese than those without PCOS. However, we have no specific interventions to induce weight loss so far and rely on drugs used to treat other symptoms of the syndrome or obesity in the general population. OBJECTIVE The objective of this study is to compare the effectiveness of metformin, inositol, liraglutide and orlistat to induce weight loss in women with PCOS and overweight/obesity. METHODS A search was conducted using the MEDLINE, EMBASE, PubMed and CENTRAL databases. Individually randomized, parallel group trials that evaluated the effects of these pharmacological treatments among adults or adolescents with PCOS and overweight/obesity, compared with a placebo or metformin group, were considered eligible. Registration number: PROSPERO CRD 42017076625. RESULTS Twenty-three trials reporting on 941 women were included in the network meta-analysis. The amount of weight lost differed significantly among the drugs (in descending order): liraglutide, orlistat and metformin. Liraglutide alone, liraglutide/metformin and metformin alone significantly reduced waist circumference, but no change was found with orlistat. Data for waist-to-hip ratio were only available for metformin, which had no significant effect. CONCLUSION Liraglutide appears superior to the other drugs in reducing weight and waist circumference.

Abstract
Introduction Polycystic ovary syndrome is one of the most common endocrinopathies in young
women, and it affects 6% to 8% of women in reproductive age.
Hyperandrogenism is the hallmark of polycystic ovary syndrome. The aim of
the present study was to evaluate the effects of orlistat on weight loss and
serum androgen levels among Iranian women with polycystic ovary
syndrome. Methods The present study was carried out in the clinic of Infertility and
Reproductive Health Research Center, Shahid Beheshti University of Medical
Sciences, Tehran, Iran. Thirty-two patients with polycystic ovary syndrome
were randomly enrolled. We measured serum androgens (Testosterone,
17α-hydroxyprogesterone, dehydroepiandrosterone and sex
hormone-binding globulin) before and after 12 weeks of treatment with
orlistat. We used the Rotterdam Criteria for all patients and transvaginal
sonography was performed. Results The mean age of patients was 27.75±6.22 and the mean body mass index
was 32.69±0.94 kg/m2. Comparing with baseline, treatment
with orlistat resulted in a significant reduction in weight, BMI, and waist
circumference (p=0.001). We also found a remarkable
reduction in total testosterone levels (p>0.001).
Treatment improved the sex hormone-binding globulin plasma levels, but the
improvement was not statistically significant. There was no reduction in
other androgen levels. Conclusion This study showed a significant reduction of weight and total testosterone
level - the most important androgen in polycystic ovary syndrome - after 12
weeks of treatment with orlistat. Therefore, it seems that a short course of
orlistat can be useful in the management of patients with polycystic ovary
syndrome.

Abstract
Background Polycystic ovarian syndrome (PCOS), a commonly prevalent endocrinopathy among reproductive age group women, is most often associated with obesity. Increased insulin resistance appears to be the central pathophysiologic mechanism responsible for various complications of PCOS. This makes 'weight loss' as the first-line treatment approach in PCOS. So various trials have tried to compare metformin (an insulin-sensitizing agent) and orlistat (an anti-obesity drug) aiming to achieve weight loss and hence higher ovulation rate for the group of obese PCOS patients. Keeping an eye on all these background facts, we designed this systematic review and metaanalysis to compare the effects of metformin and orlistat on various aspects of PCOS and to pick the better among the two drugs. Materials and Methods This is a systemic review of randomized control trials that studied the effectiveness of orlistat versus metformin in terms of improvement in ovulation rate, weight loss, lipid profile, etc. Systematic literature search over the period January 2000-December 2016 was performed in the following electronic databases: Medline, embase, google scholar, pubmed and The Cochrane Library and only randomized controlled clinical trials were included in our study. All authors carefully went through all sources of information independently. Results According to this study, weight loss, testosterone level after 4 weeks of treatment, total serum cholesterol and triglyceride level showed significant fall in orlistat-treated group. Conclusion Our review shows that orlistat is a more effective drug than metformin and should be the preferred drug in obese PCOS in combination with weight loss.

Abstract
INTRODUCTION Our aim was to evaluate the effects of metformin and orlistat on body composition and glucose-insulin homeostasis in obese premenopausal women. MATERIAL AND METHODS Seventy-three obese premenopausal Caucasian women aged 32.4 ±8.3 years were treated with either metformin (1000 mg/day; n = 37) or orlistat (360 mg/day; n = 36). Anthropometric parameters were measured using dual-energy X-ray absorptiometry. Glucose tolerance, using the oral glucose tolerance test; insulin resistance, using the homeostasis model assessment (HOMA-IR); and insulin sensitivity, using the Matsuda insulin sensitivity index (ISI Matsuda), were assessed at the commencement of the study and after 3 months. RESULTS Those treated with orlistat showed greater weight loss (-9.4 ±2.3 vs. -4.9 ±1.3 kg, p < 0.05) and decrease of fat mass (-5.4 ±3.0 vs. -3.5 ±0.7 kg, p < 0.05) than those treated with metformin. The percentage of android and gynoid fat deposits was reduced in both groups; however, a greater decrease in android fat was observed in those treated with metformin. Improvement in ISI Matsuda and post-load insulin were similar in both groups. High initial post-load insulin and low ISI Matsuda corresponded with reductions in total fat, trunk fat, and waist circumference in both groups, and a decrease in android fat in those treated with metformin. CONCLUSIONS Orlistat treatment resulted in greater weight loss and improvement in body composition; metformin treatment resulted in a reduction of android fat. Both drugs produced a comparable improvement in insulin/glucose homeostasis. Overall, insulin-resistant women showed improvement with treatment, irrespective of which drug was used.

Abstract
BACKGROUND The effects of exercise, metformin, and orlistat on anthropometric parameters, lipid profile, endocrine parameters, and ovulation in polycystic ovarian syndrome (PCOS) women were compared. AIM The aim was to study the efficacy of orlistat compared with metformin and exercise in PCOS. DESIGN Randomized control trial. METHODS A total of 90 eligible PCOS women were randomly assigned to receive either of the two drugs (orlistat or metformin) in combination with lifestyle interventions or as controls where they received lifestyle interventions alone. Anthropometric parameters were assessed at baseline and 4 weekly intervals for 3 months. Androgen levels, insulin resistance, ovulation and conception rates and lipid profile were also assessed at the end of study. STATISTICAL ANALYSIS Statistical analysis was performed using the SPSS version 17.0. RESULTS The levels of fasting blood sugar, fasting insulin and homeostatic model assessment insulin resistance were comparable in three treatment groups. Mean total testosterone, serum hormone binding globulin, free androgen index, dehydroepiandrosterone sulfate in all arms were comparable and statistically nonsignificant. However, orlistat and metformin were more effective in reducing weight, body mass index, waist circumference and waist-hip ratio. However, side-effects were less with orlistat. Ovulation rate was 33.3%, 23.35% with orlistat and metformin group respectively, but were not statistically significant. In orlistat group, significant improvement was observed in lipid profile at the end of 3 months. Conception rates were 40% and 16.7% and 3.3% in orlistat, metformin group and control group respectively (P - 0.003). Weight loss was found to be the best predictor of ovulation with sensitivity with good sensitivity. CONCLUSION Orlistat is as effective as metformin in reducing weight and achieves similar ovulation rates in obese PCOS patients. However, orlistat has minimal side-effects and is better tolerated compared with metformin.

Abstract
OBJECTIVE Obesity is frequently present in women with the polycystic ovary syndrome (PCOS) and aggravates insulin resistance (IR) and hyperandrogenemia. We aimed to assess the effects of orlistat combined with lifestyle changes in overweight and obese women with PCOS and body mass index (BMI)-matched controls. DESIGN Prospective study. PATIENTS We studied 101 women with PCOS (age 26·1 ± 6·4 years, BMI 34·5 ± 5·9 kg/m(2) ) and 29 BMI-matched women with normal ovulating cycles. All women were instructed to follow a low-calorie diet to exercise and were treated with orlistat 120 mg tid for 6 months. MEASUREMENTS Metabolic and endocrine characteristics of PCOS, blood pressure (BP) and lipid profile. RESULTS A significant and comparable reduction in BMI was observed in women with PCOS and controls. Systolic and diastolic BP decreased only in women with PCOS. Serum low-density lipoprotein cholesterol levels decreased in both women with PCOS and controls; however, this reduction was greater in controls. In contrast, serum high-density lipoprotein cholesterol levels did not change in women with PCOS and decreased in controls. Serum triglyceride levels decreased significantly and to a comparable degree in the two groups. Similarly, markers of IR improved significantly and to a comparable degree in women with PCOS and controls. Serum testosterone levels and the free androgen index decreased significantly in women with PCOS and did not change in controls. CONCLUSIONS Orlistat combined with lifestyle changes induces substantial weight loss in women with PCOS, resulting in improvements in IR, hyperandrogenemia and cardiovascular risk factors.

Abstract
Obesity is associated with multiple adverse reproductive outcomes, but the mechanisms involved are largely unknown. Obesity has been referred to as a "complex system," defined as a system of heterogeneous parts interacting in nonlinear ways to influence the behavior of the parts as a whole. Human reproduction is also a complex system; hence the difficulty in identifying the mechanisms linking obesity and adverse reproductive function. This review discusses the adverse reproductive outcomes associated with obesity and the mechanisms involved and concludes with a discussion of public health policy with respect to the treatment of infertility in obese women.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder amongst women of reproductive age and is associated with various metabolic perturbations, in addition to chronic anovulation and factors related to androgen excess. In general, women live longer than men and develop cardiovascular disease at an older age. However, women with PCOS, as compared with age- and body mass index-matched women without the syndrome, appear to have a higher risk of insulin resistance, hyperinsulinemia, glucose intolerance, dyslipidemia, and an increased prothrombotic state, possibly resulting in a higher rate of type 2 diabetes mellitus, fatty liver disease, subclinical atherosclerosis, vascular dysfunction, and finally cardiovascular disease and mortality. Further alterations in PCOS include an increased prevalence of sleep apnea, as well as various changes in the secretion and/or function of adipokines, adipose tissue-derived proinflammatory factors and gut hormones, all of them with direct or indirect influences on the complex signaling network that regulates metabolism, insulin sensitivity, and energy homeostasis. Reviews on the cardiometabolic aspects of PCOS are rare, and our knowledge from recent studies is expanding rapidly. Therefore, it is the aim of the present review to discuss and to summarize the current knowledge, focusing on the alterations of cardiometabolic factors in women with PCOS. Further insight into this network of factors may facilitate finding therapeutic targets that should ameliorate not only ovarian dysfunction but also the various cardiometabolic alterations related to the syndrome.

Abstract
PURPOSE Comparing the effects of metformin or orlistat on hormone, lipid profile and ovulation status in obese women with polycystic ovary syndrome. METHODS A total of 80 women were prospectively recruited to receive either metformin (n = 40) or orlistat (n = 40). Weight, BMI, waist, serum LH, total serum testosterone and lipid profile were assessed at baseline and after 3 months. The subjects' ovulatory status was assessed after 3 months. RESULTS There was no significant difference in ovulation between the two treatment groups (30% vs 15%). Treatment with either drug showed a significant decline in body weight, BMI (Body Mass Index), and waist circumference, but the degree of decline in both groups was the same. Patients who were treated with orlistat, showed a significant reduction in total testosterone and serum lipid. Women in metformin group showed a significant reduction in serum LH. CONCLUSIONS Both metformin and orlistat showed a similar effect on weight loss and ovulation rates.

Insulin resistance/hyperinsulinemia and reproductive disorders in infertile women. Reprod Med Biol 2010; 9:185-190.

Abstract
Obesity, which disturbs lipid and glucose metabolism, is a recent medical concern. It threatens human health and also has adverse effects on reproductive functions by causing insulin resistance/hyperinsulinemia, especially in women with polycystic ovary syndrome (PCOS). For PCOS patients to prevent these adverse effects, it is important to take into account improving their lifestyles by exercise and proper diets. The relationship between insulin resistance/hyperinsulinemia and reproductive disorders should be understood as fully as possible in order to provide effective treatment. It is well known that insulin resistance and compensatory hyperinsulinemia can be triggered by obesity with visceral fat accumulation. Hyperinsulinemia affects granulosa cells in small follicles and theca cells. This condition induces early response to luteinizing hormones on granulosa cells of small follicles and causes premature differentiation of these cells, which eventually results in anovulation. For improvement of anovulation because of hyperinsulinemia, insulin-sensitizing agents (biguanide and thiazolidinedione derivatives) are useful. Hyperinsulinemia may adversely affect the endometrial functions and environment, and evoke implantation disturbance. Treatment with an insulin-sensitizing agent (metformin) improves the levels of glycodelin, insulin-like growth factor binding protein 1, and blood flow in spiral arteries during the peri-implantation period. It supports endometrial function, improves the endometrial environment, and facilitates embryo implantation. The rate of early pregnancy loss during the first trimester is 30-50% in women with PCOS, which is threefold higher than for normal women. Metformin treatment improves the levels of insulin, the homeostasis model assessment for insulin resistance, and plasminogen activator inhibitor activity, and decreases early pregnancy loss. It goes without saying that lifestyle change is fundamental for improving reproductive performance in addition to treatment with insulin-sensitizing agents.

Abstract
Whilst many multiparous women are obese (body mass index >30 kg/m(2)), obesity has been associated with impaired fecundity; however, the mechanism which links obesity to reduced fertility remains to be fully elucidated. Obese women, particularly those with central obesity, are less likely to conceive per cycle. Obese women suffer perturbations to the hypothalamic-pituitary-ovarian axis, menstrual cycle disturbance and are up to three times more likely to suffer oligo-/anovulation. A fine hormonal balance regulates follicular development and oocyte maturation, and it has been observed that obesity can alter the hormonal milieu. Leptin, a hormone produced by adipocytes, is elevated in obese women, and raised leptin has been associated with impaired fecundity. Obesity impairs ovulation but has also been observed to detrimentally affect endometrial development and implantation. The expression of polycystic ovary syndrome (PCOS) is regulated, in part, by weight, and so obese women with PCOS often have a more severe phenotype and experience more subfertility. Obesity also impairs the response of women to assisted conception treatments. Weight loss through lifestyle modification or bariatric surgery has been demonstrated to restore menstrual cyclicity and ovulation and improve the likelihood of conception. In this article, we will discuss the effect of obesity upon key reproductive mechanisms and its relation to fertility treatments.
