Abstract
There are currently various protocols for in vitro fertilization (IVF). For patients with polycystic ovarian syndrome (PCOS), an optimized protocol for the downregulation of pituitary follicle stimulating hormone and luteinizing hormone via gonadotropin-releasing hormone agonist (GnRHa) remains a challenge. In the present study, the primary endpoint of an ultra-long and a conventional long GnRHa protocol for intracytoplasmic sperm injection/IVF treatments of patients with PCOS was retrospectively compared. In the modified ultra-long protocol group, endometrial thickness, morphology, and blood flow were significantly improved, as compared with in the conventional long protocol group. Furthermore, the serum progestogen (P) concentrations and P/estrogen (E2) [(Px1,000/E2)] ratio on the day of human chorionic gonadotrophin administration were significantly decreased in the modified ultra-long downregulation group, whereas the pregnancy and implantation rates were significantly higher. There were no significant differences in the average number of obtained oocytes, good quality embryo rates, cancel rates, fertilization rates, abortion rates, serious ovarian hyperstimulation syndrome incidences, ectopic pregnancy rates or gonadotropin (Gn) dosages between the two groups. These results suggest that the modified ultra-long protocol plus human menopausal Gn medication may be superior to the conventional long protocol, and may lead to improved implantation and pregnancy outcomes for infertile patients with PCOS.

Abstract
PURPOSE The aim of this study is to investigate the effect of female BMI and metabolic dysfunction on blastocyst formation rate. METHODS This was a retrospective cohort study that was performed in an academic center for reproductive medicine. Patients who were normal weight, overweight with metabolic dysfunction, or obese who had ≥6 oocytes retrieved in a fresh IVF cycle were included in the study. The blastocyst formation rate was calculated from the number of ≥5 cell embryos on day 3 observed in culture until day 5 or day 6. Only good quality blastocysts were included in the calculation as defined by a morphologic grade of 3BB or better. RESULTS The blastocyst formation rate was significantly better in the normal-weight controls versus overweight/obese patients (57.2 versus 43.6 %, p < 0.007). There was no difference in blastocyst formation between the patients with a BMI 25-29.9 kg/m(2) with metabolic dysfunction and those with a BMI ≥30 kg/m(2). CONCLUSION The maternal metabolic environment has a significant impact on embryo quality as measured by blastocyst formation. A decreased blastocyst formation rate is likely a significant contributor to poorer reproductive outcomes in overweight and obese women with infertility.

Abstract
OBJECTIVE The objective of this study was to assess the relationship between BMI and oocyte number and maturity in participants who underwent minimal stimulation (mini-) or conventional IVF. METHODS Participants who underwent their first autologous cycle of either conventional (n = 219) or mini-IVF (n = 220) were divided according to their BMI to analyze IVF outcome parameters. The main outcome measure was the number of oocytes in metaphase II (MII). Secondary outcomes included the number of total oocytes retrieved, fertilized (2PN) oocytes, cleavage and blastocyst stage embryos, clinical pregnancy (CP), and live birth (LB) rates. RESULTS In conventional IVF, but not in mini-IVF, the number of total oocytes retrieved (14.5 ± 0.8 versus 8.8 ± 1.3) and MII oocytes (11.2 ± 0.7 versus 7.1 ± 1.1) were significantly lower in obese compared with normal BMI women. Multivariable linear regression adjusting for age, day 3 FSH, days of stimulation, and total gonadotropin dose demonstrated that BMI was an independent predictor of the number of MII oocytes in conventional IVF (p = 0.0004). Additionally, only in conventional IVF, BMI was negatively correlated with the total number of 2PN oocytes, as well as the number of cleavage stage embryos. CONCLUSIONS Female adiposity might impair oocyte number and maturity in conventional IVF but not in mini-IVF. These data suggest that mild ovarian stimulation might yield healthier oocytes in obese women.

Abstract
STUDY QUESTION Do prenatal exposure to cigarette smoking and birthweight influence age at menarche (AAM) in a cohort of Australian girls? SUMMARY ANSWER We find that prenatal smoke exposure and lower birthweight increase the chance of earlier menarche in accordance with theoretical predictions as do confounding factors of maternal AAM and higher BMI of the girls. WHAT IS KNOWN ALREADY Much prior research focuses on the role of the early childhood environment in determining AAM but fewer studies consider the role of the prenatal environment. Those studies that examine the prenatal period find an acceleration of maturation associated with maternal smoking and low birthweight. Life history theory predicts that early life exposure to stressful environments should promote more rapid maturation and that this timing can be established before birth, making the prenatal environment particularly important. STUDY DESIGN, SIZE, DURATION Statistical analysis of longitudinal survey data collected from a large cohort (n = 2446) of Australian children using data from birth to 12-13 years of age. PARTICIPANTS/MATERIALS, SETTING, METHODS Owing to missing data, 1493 girls were included in the final analysis. Using cox regression, we examine how (i) maternal cigarette smoking during gestation and (ii) birthweight influence girls' AAM. Cox regression was used because not all girls had reached menarche. MAIN RESULTS AND THE ROLE OF CHANCE We find that older maternal AAM (hazards ratio (HR): 0.75, confidence interval (CI) (95%): 0.71-0.79) and higher birthweight (HR: 0.86, CI (95%): 0.75-0.97) lower the chance of earlier menarche; while higher girls' BMI at 8-9 years (HR: 1.12, CI (95%): 1.10-1.15), and maternal cigarette smoking on 'most days' during gestation (HR: 1.40, CI (95%): 1.10-1.79 with 'no smoking' as the reference level) increased the chance of earlier menarche. All factors were statistically significant at P = 0.05. LIMITATIONS, REASONS FOR CAUTION Not all girls had reached menarche, necessitating the use of cox regression. As with other longitudinal studies, there was study sample attrition and some missing data, particularly in reports of maternal smoking. In addition, as the degree of bias in the missing data is unknown, possible inaccurate reporting of maternal smoking may influence the results of birthweight on AAM. WIDER IMPLICATIONS OF THE FINDINGS Because of the association between younger AAM and higher risk of uterine, endometrial and breast cancer development, our finding adds to the need to consider the stress caused by prenatal smoke exposure as an important health risk. In addition, this study needs to be extended, when the same girls are 14-15 years of age, and on a larger dataset from a younger cohort within the same Australian Government project. STUDY FUNDING/COMPETING INTERESTS No funding was received for this study and there are no competing interests to declare.

Abstract
OBJECTIVE To determine whether obesity alters genes important in cellular growth and inflammation in human cumulus granulosa cells (GCs). METHODS Eight reproductive-aged women who underwent controlled ovarian hyperstimulation followed by oocyte retrieval for in vitro fertilization were enrolled. Cumulus GC RNA was extracted and processed for microarray analysis on Affymetrix Human Genome U133 Plus 2.0 chips. Gene expression data were validated on GCs from additional biologically similar samples using quantitative real-time polymerase chain reaction (RT-PCR). Comparison in gene expression was made between women with body mass index (BMI) <25 kg/m(2) (group 1; n = 4) and those with BMI ≥25 kg/m(2) (group 2; n = 4). RESULTS Groups 1 and 2 had significantly different BMI (21.4 ± 1.4 vs 30.4 ± 2.7 kg/m(2), respectively; P = .02) but did not differ in age (30.5 ± 1.7 vs 32.7 ± 0.3 years, respectively; P = .3). Comparative analysis of gene expression profiles by supervised clustering between group 1 versus group 2 resulted in the selection of 7 differentially expressed genes: fibroblast growth factor 12 (FGF-12), protein phosphatase 1-like (PPM1L), zinc finger protein multitype 2 (ZFPM2), forkhead box M1 (FOXM1), cell division cycle 20 (CDC20), interleukin 1 receptor-like 1 (IL1RL1), and growth arrest-specific protein 7 (GAS7). FOXM1, CDC20, and GAS7 were downregulated while FGF-12 and PPM1L were upregulated in group 2 when compared to group 1. Validation with RT-PCR confirmed the microarray data except for ZFPM2 and IL1RL. As BMI increased, expression of FOXM1 significantly decreased (r = -.60, P = .048). CONCLUSIONS Adiposity is associated with changes in the expression of genes important in cellular growth, cell cycle progression, and inflammation. The upregulation of the metabolic regulator gene PPM1L suggests that adiposity induces an abnormal metabolic follicular environment, potentially altering folliculogenesis and oocyte quality.

Abstract
Infertility is a relatively common condition, greatly affecting couples medically and psychologically. Although infertility treatment is safe, it can be time-intensive, expensive and increase the risk of multiple gestations. Thus, to reduce costs and risks, couples may initially consider lifestyle change to increase their fertility and chances of pregnancy. For many of the diet factors studied (for example: caffeine, soy, protein, iron), there are conflicting data. However, there are some items men and women consume that are detrimental to fertility, such as alcohol and tobacco. The data on exercise are varied but may have an effect on ovulation and fertility - positive or negative. Body mass index appears to impact fertility also, with obesity in both men and women negatively affecting pregnancy rates. In addition, there remains concern and a growing body of research on environmental toxin exposures and reproductive health. Finally, supporting patients through infertility diagnosis and treatment is critical, as psychological stress may impact conception. It is imperative that the relationship between lifestyle factors and fertility continue to be explored as to lessen the morbidity associated with infertility.

Abstract
BACKGROUND Infertility patients are increasingly using complementary and alternative medicine (CAM) to supplement or replace conventional fertility treatments. The objective of this study was to determine the roles of CAM practitioners in the support and treatment of infertility. METHODS Ten semi-structured interviews were conducted in Ottawa, Canada in 2011 with CAM practitioners who specialized in naturopathy, acupuncture, traditional Chinese medicine, hypnotherapy and integrated medicine. RESULTS CAM practitioners played an active role in both treatment and support of infertility, using a holistic, interdisciplinary and individualized approach. CAM practitioners recognized biological but also environmental and psychosomatic determinants of infertility. Participants were receptive to working with physicians, however little collaboration was described. CONCLUSIONS Integrated infertility patient care through both collaboration with CAM practitioners and incorporation of CAM's holistic, individualized and interdisciplinary approaches would greatly benefit infertility patients.

Abstract
Chemo- and radiation therapies used to treat cancer can have the unintended effect of making patients infertile. Clinically established fertility preservation methods, such as egg and embryo cryopreservation, are not applicable to all patients, which has motivated the development of strategies that involve ovarian tissue removal and cryopreservation before the first sterilizing treatment. To restore fertility at a later date, the early-stage follicles present in the tissue must be matured to produce functional oocytes, a process that is not possible using existing cell culture technologies. This review describes the application of tissue engineering principles to promote ovarian follicle maturation and produce mature oocytes through either in vitro culture or transplantation. The design principles for these engineered systems are presented, along with identification of emerging opportunities in reproductive biology.

Abstract
OBJECTIVE To investigate the association of individual follicular fluid (FF) leptin and adiponectin levels with the quality of the corresponding oocyte and embryo. METHODS We prospectively enrolled 67 women who underwent controlled ovarian hyperstimulation with 89 FF samples. FF and the corresponding oocyte was obtained from a single dominant preovulatory follicle at the time of oocyte retrieval. Concentrations of leptin and adiponectin were measured by enzyme-linked immunosorbent assay in an individual follicle. The oocyte quality, fertilization rate, and corresponding embryo development were assessed. RESULTS The FF level of leptin was significantly associated with body mass index (r=0.334, p<0.01). The FF adiponectin level was significantly higher in the normal fertilization group than the abnormal fertilization group (p=0.009) in the non-obese women. A lower FF leptin level was associated with a trend toward mature oocytes, normal fertilization, and good embryo quality, although these relationships were not statistically significant. The leptin:adiponectin ratio of FF did not differ significantly according to oocyte and embryo quality. The quality of the oocyte and embryo was not associated with the FF leptin level tertile. However, the normal fertilization rate was positively associated with FF adiponectin level tertile. There was a trend towards improved oocytes and normal fertilization rates with the lowest tertile of the FF leptin:adiponectin ratio, but this difference was not statistically significant. CONCLUSION Our results suggest that a high FF adiponectin concentration could be a predictor of normal fertilization. However, the FF leptin concentration and leptin:adiponectin ratio is not significantly related to oocyte maturity and corresponding embryo development.

Abstract
The current study indicates that life-long intake, from early-life, of an obesogenic diet with high saturated-fat (HSF) content induces dyslipidemia (high plasma concentrations of triglycerides in concurrence with low concentrations of HDL-cholesterol) in obese swine with leptin resistance (Iberian sows). In case of pregnancy, ovarian features (ovulatory efficiency and luteal steroidogenesis) of sows fed with HSF are not affected but embryo features are affected at so early stages like 28 days of pregnancy (first quarter), although embryo viability was still not affected. In this way, offspring from HSF sows showed a higher incidence of alterations in their developmental trajectory, mainly due to a higher incidence of growth retardation, in their steroidogenic activity and in their availability of triglycerides and cholesterol. In conclusion, the results obtained in the present study illustrate the deleterious effects of maternal dyslipidemia, induced by the intake of HSF diets, on the oestradiol secretion of the conceptuses at early-pregnancy stages and, thus, on their developmental and metabolic features. This article is part of a Special Issue entitled 'Pregnancy and steroids'.

Abstract
ABSTRACT
Background
Various prognostic factors in assisted reproduction procedures have been described and analyzed which includes woman's age, cause of infertility, ovarian response and uterine receptivity, the semen quality, and the body mass index (BMI). Optimal BMI is required for an optimal response. There is controversy among various reports, which is partly caused by the varying focus of investigators and differences in study designs, which led us to examine the relationship between BMI, in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) outcome in our unit.
Objective
To study impact of BMI on IVF outcome prospectively

It is a prospective study over a period of 1 year in the age group 25 to 35 years attending the IVF clinic was conducted at a tertiary infertility center in Bangalore, India between November 2010 and October 2011.
Results
There is a close association of increased BMl in particular when BMl is > 30 kg/m2 and the reduced outcomes of IVF/ ICSI treatment in the form of decreased clinical pregnancy and higher early pregnancy loss. Furthermore, increased BMl is related to higher dosage and duration of gonadotropins requirement increased risk of cancellation and fewer collected oocytes.
Conclusion
Obesity is associated with an increased risk of early pregnancy loss. Also need of high dose of gonadotropin, less number of collected oocytes is observed. Implantation rate, pregnancy rate and miscarriage rate was comparable but live births are high in normal weight and overweight as compared to extremes of BMI. So will be appropriate to recommend life style modifications including weight loss to achieve an appropriate BMI prior to IVF.

Abstract
STUDY QUESTION What is the role of knowledge, perceived vulnerability and level of risk of infertility in women's intentions to take action to improve their chance of becoming pregnant (i.e. by seeking medical and/or non-medical help and making lifestyle changes)? SUMMARY ANSWER Women younger than age 35 were more likely to intend to take measures to improve their chance of conceiving when they were knowledgeable about fertility and felt susceptible to infertility; however, there was no such association in older women. WHAT IS KNOWN ALREADY The majority of young adults wish to become parents but many are jeopardizing their chances by engaging in behaviours that decrease fertility (e.g. smoking, not seeking timely medical advice when faced with problems conceiving). Research is needed to establish what motivates people to take steps to optimize their chances of pregnancy. The Health Belief Model (HBM) postulates that knowledge and beliefs about susceptibility to infertility are critical in whether people will engage in fertility-optimizing behaviours. STUDY DESIGN, SIZE AND DURATION This cross-sectional survey included 1345 childless women (trying to conceive and having never engaged in fertility medical treatment) from the International Fertility Decision-Making Study (IFDMS). PARTICIPANTS/MATERIALS, SETTING, METHODS Infertility risk factors were determined using the FertiSTAT. The Cardiff Fertility Knowledge Scale (CFKS) assessed fertility knowledge. Perceived susceptibility was defined as whether a fertility problem was suspected. The outcome measure was intentions to optimize one's fertility by making lifestyle changes and/or seeking help. MAIN RESULTS AND THE ROLE OF CHANCE In this study, 75.5% of women had an infertility risk factor and 60.3% suspected a fertility problem. The average correct score on the CFKS was 51.9%. Intentions to optimize fertility were lower among women who were heavy smokers (P < 0.05) and who had been trying to conceive for a year or over (P < 0.01), while intentions to optimize fertility were greater among those with a higher body mass index or greater knowledge and those who suspected a fertility problem (all P < 0.001). These overall effects were qualified in some subgroups. Heavy smokers were more likely to intend to seek medical help when they had greater knowledge (P < 0.001) and women having difficulty conceiving were more likely to intend to seek medical help if they felt susceptible to infertility (P < 0.001). Heavy smokers who were knowledgeable intended to change their lifestyle only when they felt they had a fertility problem (P < 0.01). Intentions to change were not dependent on knowledge and perceived susceptibility in older women. LIMITATIONS, REASONS FOR CAUTION The data were cross-sectional and thus we cannot infer causality. The results may have been affected by the sample profile, which was biased towards high levels of perceived susceptibility and low levels of knowledge. WIDER IMPLICATIONS OF THE FINDINGS To maximize impact, educational campaigns should take into account the presence and type of infertility risk factors in the target audience.

Abstract
In 2002, 15.4% of women of childbearing age in the USA reported struggles with infertility. Over the past 3 decades, drugs and assisted reproductive technologies have been developed to treat infertility, but treatment is costly. Since 1985, several states have adopted insurance mandates that require providers to cover or offer infertility treatments. In this paper, I examine the impact of strong mandate-to-cover laws on multiple births, which are associated with infertility treatment use. I also investigate whether the laws had heterogeneous treatment effects. Using birth certificate data from 1980-2002, I show that the laws had a small and statistically insignificant impact on multiple birth rates. However, I find that there were over 5300 mandate-induced triplet and higher-order births over the period, for which the delivery costs alone are estimated to be over $900 million. Increases in multiple birth rates are only observed for women over 30 and are greater for women who are married, white, or have a college degree. This is consistent with previous work, which finds that the mandates did not reduce disparities in treatment use.

What are the risks of the assisted reproductive technologies (ART) and how can they be minimized? Reprod Med Biol 2013; 12:151-158.

Abstract
Although assisted reproductive technologies (ART) have become established procedures performed around the world, there are still many unanswered questions regarding safety. Possible risks associated with infertility and ART include (1) those inherent to pregnancy, delivery, and childhood; (2) those associated with the infertility itself and its causes; and (3) risks iatrogenic to ART. Although there are many potential risks associated with ART, it has become clear that the major risk is multiple pregnancy and its consequences. Major efforts are warranted to reduce the risk of multiple gestations with IVF, but it is also clear that single-embryo transfer is not the solution in all cases. Moreover, several studies have now documented that perinatal outcomes are somewhat poorer in IVF singleton infants than in spontaneously conceived singletons, but it is not clear if this increased risk is due to the ART or the infertility. Concerns about the impact of abnormalities in genomic imprinting persist at this time, as do risks associated with the culture conditions and even our environment. Only time will tell if children born following ART are at any increased risk of developing certain chronic diseases as they age. In any case, the risks to IVF children and mothers are likely to remain higher than those for children and mothers conceived spontaneously without medical assistance. However, since there have been over 5 million births after ART worldwide, and the vast majority of pregnancies and children have been essentially "normal", it is obvious that any excess risk must be relatively small. The normality of most pregnancies mandates that extreme care be exercised in making any changes to current practice.

Abstract
In modern society, obesity has become a major health problem and has been associated with impaired fertility. The aim of this study is to assess the role of obesity in women undergoing controlled ovarian hyperstimulation (COH) stimulated either with GnRH agonists or with GnRH antagonists. Records of 463 women undergoing in vitro fertilization (IVF) treatment were reviewed. The influence of body mass index (BMI) on treatment outcome was examined, after accounting for differences in stimulation protocols. In the agonist group (286 patients), the total amount of gonadotropins used was significantly higher in patients with a BMI ≥ 25 kg/m², when compared to those with a normal BMI. The same result was found in the antagonist group (177 patients). No significant differences were found in length of stimulation, number of oocytes retrieved or number of embryos transferred. In both the antagonist and the agonist group, the number of clinical pregnancies was found to be higher in patients with normal BMI, suggesting that obesity could impair the ovarian response to exogenous gonadotropins. Considering the results obtained and the many theoretical advantages of GnRH antagonists, ovarian stimulation with GnRH antagonists is an efficient treatment for both women with normal and high BMI.

Abstract
OBJECTIVE To assess the relation between body mass index (BMI) and short-term weight change with assisted reproductive technology (ART) outcomes. DESIGN Prospective cohort study. SETTING Fertility center. PATIENT(S) A total of 170 women undergoing 233 ART cycles. INTERVENTION(S) Baseline BMI and short-term weight change were related to ART outcomes. Regression models accounting for repeated observations were used to adjust data for potential confounders. MAIN OUTCOME MEASURE(S) Peak E2 levels, oocyte yield, MII yield, fertilization rate, embryo quality, postive [beta]-hCH, clinical pregnancy and live birth rates. RESULT(S) Overweight and obesity were associated with lower live birth rates. The adjusted live birth rate (95% confidence interval) was 42% (28%-58%) among women with a BMI between 20 and 22.4 kg/m(2) and 23% (14%-36%) among overweight or obese women. Short-term weight loss was associated with a higher proportion of metaphase II (MII) oocytes retrieved. The adjusted proportion of MII eggs was 91% (87%-94%) for women who lost 3 kg or more and 86% (81%-89%) for women whose weight remained stable. This association was stronger among women who were overweight or obese at baseline. Short-term weight loss was unrelated to positive β-hCG, clinical pregnancy, or live birth rates. CONCLUSION(S) Overweight and obesity were related to lower live birth rates in women undergoing ART. Short-term weight loss was related to higher MII yield, particularly among overweight and obese women, but unrelated to clinical outcomes.

Abstract
BACKGROUND Based on a presumed negative impact of overweight and obesity on reproductive capacity and pregnancy outcome, some national guidelines and clinicians have argued that there should be an upper limit for a woman's BMI to access assisted reproductive technologies (ART). However, evidence on the risk of complications or expected success rate of ART in obese women is scarce. We therefore performed a systematic review on the subject. METHODS We searched the literature for studies reporting on complications or success rates in overweight and obese women undergoing ART. Articles were scored on methodological quality. We calculated pooled odds ratios (ORs) to express the association between overweight and obesity on the one hand, and complications and success rates of ART on the other hand. We only pooled results if data were available per woman instead of per cycle or embryo transfer. RESULTS We detected 14 studies that reported on the association between overweight and complications during or after ART, of which 6 reported on ovarian hyperstimulation syndrome (OHSS), 7 on multiple pregnancies and 6 on ectopic pregnancies. None of the individual studies found a positive association between overweight and ART complications. The pooled ORs for overweight versus normal weight for OHSS, multiple pregnancy and ectopic pregnancy were 1.0 [95% confidence interval (CI) 0.77-1.3], 0.97 (95% CI 0.91-1.04) and 0.96 (95% CI 0.54-1.7), respectively. In 27 studies that reported on BMI and the success of ART, the pooled ORs for overweight versus normal weight on live birth, ongoing and clinical pregnancy following ART were OR 0.90 (95% CI 0.82-1.0), 1.01 (95% CI 0.75-1.4) and OR 0.94 (95% CI 0.69-1.3), respectively. CONCLUSIONS Data on complications following ART are scarce and therefore a registration system should be implemented in order to gain more insight into this subject. In the available literature, there is no evidence of overweight or obesity increasing the risk of complications following ART. Furthermore, they only marginally reduce the success rates. Based on the currently available data, overweight and obesity in itself should not be a reason to withhold ART.

Abstract
BACKGROUND In IVF treatment a considerable proportion of women are faced with a low number of oocytes retrieved. These poor responders have reduced pregnancy rates compared with normal responders. However, this may not be applicable to all poor responders. This review aims at identifying patient characteristics and ovarian reserve tests (ORT) that will determine prognosis for pregnancy in poor responders. METHODS A systematic search was conducted in PubMed, Embase, Cochrane and SCOPUS databases in April 2010. Studies regarding patient characteristics or ORT in poor responders and their pregnancy prospects were included. All included papers were summarized in descriptive tables. RESULTS Nineteen studies were included. Pooled data of six studies comparing poor and normal responders demonstrated clearly lower pregnancy rates in poor responders (14.8 versus 34.5%). Ten studies indicated that older poor responders have a lower range of pregnancy rates compared with younger (1.5-12.7 versus 13.0-35%, respectively). Four studies showed that pregnancy prospects become reduced when fewer oocytes are retrieved (0-7% with 1 oocyte versus 11.5-18.6% with 4 oocytes). Five studies concerning pregnancy rates in subsequent cycles suggested a more favourable outcome in unexpected poor responders, and if ≥2 oocytes were retrieved. CONCLUSIONS Poor responders are not a homogeneous group of women with regards to pregnancy prospects. Female age and number of oocytes retrieved in particular will modulate the chances for pregnancy in current and subsequent cycles. Applying these criteria will allow the identification of couples with a reasonable prognosis and balanced decision-making on the management of poor responders.

Abstract
BACKGROUND Ovarian tissue cryopreservation is an emerging fertility preservation option, and culturing follicles isolated from this tissue to obtain mature gametes may ultimately be the best solution for patients for whom transplantation is contraindicated. It is unclear, however, how patient-specific variables (including age, weight and menstrual cycle stage) impact follicle growth and quality during three-dimensional culture. METHODS We used a mouse model to systematically determine how these variables impact in vitro follicle growth. We characterized metabolic and hormonal profiles of mice at specific ages, weights and cycle stages and secondary follicles from these cohorts were isolated and cultured. We then assessed follicle survival, growth and function, as well as meiotic competence and spindle morphology of the resulting oocytes. RESULTS We found that older mice and mice with increased body weight had higher serum cholesterol, abnormal glucose tolerance and lower levels of circulating Anti-Müllerian hormone compared with younger and leaner controls. Secondary follicles isolated from different cohorts and grown in vitro had indistinguishable growth trajectories. However, the follicles isolated from older and heavier mice and those in diestrus had altered hormone profiles. These follicles contained oocytes with reduced meiotic competence and produced oocytes with greater spindle defects. CONCLUSIONS These results suggest that the original physical environment of the follicle within the ovary can impact its function when isolated and cultured. These findings are valuable as we begin to use in vitro follicle growth technology for a heterogeneous fertility preservation patient population.

Abstract
Weight, fat mass and obesity have been shown to play a major role in female reproduction. Obese women have a greater risk than nonobese women of infertility and they fail to become pregnant in both natural and assisted conception cycles. This cannot be explained only by their lack of ovulation. There are several potential mechanisms. On one hand, the endometrium seems to be partially responsible for this low fecundity in obese women. On the other hand, the oocyte seems to be implied. In a model of obese mouse, maternal obesity prior to conception is associated with altered mitochondria in mouse oocytes and an increased generation of reactive oxygen species (ROS). Furthermore, compared with controls, obese mice have significantly more decreased embryonic IGF-IR staining, smaller fetuses and smaller pups. In this model, all weaned pups have been fed with a regular diet. At 13 weeks, pups delivered from obese mice were significantly larger, and these pups demonstrated early development of a metabolic-type syndrome. These findings suggest that maternal obesity has adverse effects as early as the oocyte and preimplantation embryo stages and that these effects may contribute to lasting morbidity in offspring, underscoring the importance of optimal maternal weight and nutrition before conception.

Abstract
BACKGROUND To determine whether women with extremely low-serum anti-Mullerian hormone (AMH) levels (<0.1-0.4 ng/ml) still demonstrate live birth potential with assisted reproduction and whether such potential is age dependent. METHODS Between January 2006 and October 2009, 128 consecutive infertility patients with AMH ≤0.4 ng/ml were retrospectively evaluated for pregnancy chances and live birth rates after IVF. RESULTS Patients presented at a mean (±SD) age of 40.8 ± 4.1 years, with mean (±SD) baseline FSH of 15.7 ± 11.1 mIU/ml and mean (±SD) AMH of 0.2 ± 0.1 ng/ml. One hundred and twenty-eight women underwent a total of 254 IVF cycles. Twenty clinical pregnancies were recorded (7.9% per cycle start [95% confidence interval (CI): 4.9-11.9%]; 15.6% cumulative [CI: 9.8-23.1%]). These pregnancies resulted in 13 live births in 12 women (i.e. 11 singletons and a pair of twins) and 8 patients miscarried. Eight deliveries occurred after the first cycle (6.3% per cycle start) and four after subsequent IVF cycles (3.2%). When evaluated according to female age, 70 women ≤42 years presented with 16 clinical pregnancies that resulted in 10 deliveries (14.3%), while 58 patients >42 years presented with four clinical pregnancies that resulted in 2 deliveries (3.4%), representing a reduced pregnancy chance (P = 0.013) and delivery rate (P = 0.036) versus age ≤42 years. CONCLUSIONS With extremely low-serum AMH levels, moderate, but reasonable pregnancy and live birth rates are still possible. Extremely low AMH levels do not seem to represent an appropriate marker for withholding fertility treatment.

Abstract
Metabolic syndrome affects one in four women in the USA, and the incidence is rising every year. Metabolic syndrome is strongly associated with development of coronary artery disease and diabetes. Women of reproductive age are not spared from the complications of metabolic syndrome, which overlaps with obesity and polycystic ovary syndrome (PCOS), both of which are linked to infertility and poor reproductive outcome. Therefore, the relationship between the metabolic syndrome and reproductive dysfunction is an active area of study. In this review, we discuss the animal and human data available to determine if the abnormality is at the level of the ovary and/or endometrium, and discuss the underlying mechanisms causing the associated poor reproductive outcomes.

Abstract
Prediction of assisted reproduction treatment outcome has been the focus of clinical research for many years, with a variety of prognostic models describing the probability of an ongoing pregnancy or a live birth. This study assessed whether serum anti-Müllerian hormone (AMH) concentrations may be incorporated into a model to enhance the prediction of a live birth in women undergoing their first IVF cycle, by analysing a database containing clinical and laboratory information on IVF cycles carried out between 2005 and 2008 at the Mother-Infant Department of University Hospital, Modena. Logistic regression was used to examine the association of live birth with baseline patient characteristics. Only AMH and age were demonstrated in regression analysis to predict live birth, so a model solely based on these two criteria was generated. The model permitted the identification of live birth with a sensitivity of 79.2% and a specificity of only 44.2%. In the prediction of a live birth following IVF, a distinction, however moderate, can be made between couples with a good and a poor prognosis. The success of IVF was found to mainly depend on maternal age and serum AMH concentrations, one of the most relevant and valuable markers of ovarian reserve.

Abstract
OBJECTIVES To evaluate the proportion of women with threatened miscarriage (TM) who proceed to miscarriage in a population of single ethnicity and to investigate prospectively their risk of adverse pregnancy outcome in relationship with the cytokines levels in their circulation. METHODS We conducted a prospective observational study over a period of 1 year of 94 Maltese women presenting with TM at the same hospital and compared their clinical data with those of 564 age-matched controls from the National Obstetric Information System (NOIS) of Malta. Main outcome measures included gestational age and weight at delivery and incidence of adverse pregnancy outcomes. A pilot study was carried out, where in subgroups of 10 women with TM (n=10), non-pregnant women (n=12), normal pregnant controls (n=9) and women presenting with missed-miscarriage (n=11), the plasma levels of β-human chorionic gonadotrophin (β-hCG), tumour necrosis factor α (TNFα), interferon γ (IFNγ), interleukin-6 (IL-6), interleukin-10 (IL-10) and TNF-receptors 1 (R1) and 2 (R2) were measured. RESULTS Of the women presenting with TM, 25 (26.6%) proceeded to complete miscarriage. The TM group had also a significantly higher incidence of antepartum haemorrhage (p<0.005), pre-eclampsia (p<0.05), foetal growth restriction (p<0.05), premature labour (p<0.001) and retained placenta (p<0.005). In the pilot biochemical analysis, significantly (p<0.05) higher levels of TNFα and lower levels of TNFR2 were found in the TM subgroup compared to non-pregnant controls. The ratio TNFα/IL-10 was significantly (p<0.05) higher and the β-hCG levels was significantly lower (p<0.01) in missed-miscarriage and non-pregnant subgroups than in TM and normal pregnant controls. The IFNγ/1L-10 and IFNγ/1L-6 ratio were significantly (<0.001) different between the four subgroups with the lowest level found in TM. No similar gradient was found for the TNFα/1L-6 ratio. CONCLUSION Women presenting with TM are at significantly increased risk of adverse pregnancy outcome and the pathophysiology of these conditions involves a change in the Th1/Th2 balance. Changes in levels of cytokines could help to predict and thus prevent the development of some of these complications.

Abstract
Infertility affects approximately one in six couples during their lifetime. Obesity affects approximately half of the general population and is thus a common problem among the fertile population. Obese women have a higher prevalence of infertility compared with their lean counterparts. The majority of women with an ovulatory disorder contributing to their infertility have polycystic ovary syndrome (PCOS) and a significant proportion of women with PCOS are obese. Ovulation disorders and obesity-associated infertility represent a group of infertile couples that are relatively simple to treat. Maternal morbidity, mortality and fetal anomalies are increased with obesity and the success of assisted reproductive technology (ART) treatments is significantly reduced for obese women. Body mass index (BMI) treatment limits for ART throughout the UK vary. The mainstay for treatment is weight loss, which improves both natural fertility and conception rates with ART. The most cost-effective treatment strategy for obese infertile women is weight reduction with a hypo-caloric diet. Assisted reproduction is preferable in women with a BMI of 30 kg/m(2) or less and weight loss strategies should be employed within primary care to achieve that goal prior to referral.

Abstract
BACKGROUND Clinical infertility is a prevalent problem with significant financial and psychosocial costs. Modifiable lifestyle factors exist that may affect a person's time to conception and their chance of having a healthy, live birth. However, no guideline delineates what preconception advice should be offered to people presenting for infertility treatment. AIM The aim of this article is to review the literature regarding modifiable lifestyle factors in people seeking infertility treatment. RESULTS A person's time to pregnancy and their chance of having a healthy, live birth may be affected by factors such as weight, vitamin and iodine intake, alcohol and caffeine consumption, smoking, substance abuse, stress, environmental pollutants, vaccinations and oxidative stress. CONCLUSIONS Advice on modifiable lifestyle factors should be given to people presenting for infertility treatment to help them make positive changes that may improve their chances of pregnancy and delivering a healthy, live baby. Developing a guideline for this would be a prudent step towards helping clinicians to implement this aspect of preconception care.

Abstract
Background In the Netherlands, 30% of subfertile women are overweight or obese, and at present there is no agreement on fertility care for them. Data from observational and small intervention studies suggest that reduction of weight will increase the chances of conception, decrease pregnancy complications and improve perinatal outcome, but this has not been confirmed in randomised controlled trials. This study will assess the cost and effects of a six-months structured lifestyle program aiming at weight reduction followed by conventional fertility care (intervention group) as compared to conventional fertility care only (control group) in overweight and obese subfertile women. We hypothesize that the intervention will decrease the need for fertility treatment, diminish overweight-related pregnancy complications, and will improve perinatal outcome. Methods/Design Multicenter randomised controlled trial in subfertile women (age 18-39 year) with a body mass index between 29 and 40 kg/m2. Exclusion criteria are azoospermia, use of donor semen, severe endometriosis, premature ovarian failure, endocrinopathies or pre-existent hypertensive disorders. In the intervention group the aim is a weight loss of at least 5% to10% in a six-month period, to be achieved by the combination of a diet, increase of physical activity and behavioural modification. After six months, in case no conception has been achieved, these patients will start fertility treatment according to the Dutch fertility guidelines. In the control group treatment will be started according to Dutch fertility guidelines, independently of the patient's weight. Outcome measures and analysis The primary outcome measure is a healthy singleton born after at least 37 weeks of gestation after vaginal delivery. Secondary outcome parameters including pregnancy outcome and complications, percentage of women needing fertility treatment, clinical and ongoing pregnancy rates, body weight, quality of life and costs. Data will be analysed according to the intention to treat principle, and cost-effectiveness analysis will be performed to compare the costs and health effects in the intervention and control group. Discussion The trial will provide evidence for costs and effects of a lifestyle intervention aiming at weight reduction in overweight and obese subfertile women and will offer guidance to clinicians for the treatment of these patients.

Abstract
BACKGROUND Various models have been developed for the prediction of pregnancy after in vitro fertilization (IVF). These models differ from one another in the predictors they include. We performed a systematic review and meta-analysis to identify the most relevant predictors for success in IVF. METHODS We systematically searched MEDLINE and EMBASE for studies evaluating IVF/ICSI outcome. Studies were included if they reported an unconditional odds ratio (OR) or whenever one could be calculated for one or more of the following factors: age, type of infertility, indication, duration of infertility, basal FSH, number of oocytes, fertilization method, number of embryos transferred and embryo quality. RESULTS Fourteen studies were identified. A summary OR could be calculated for five factors. We found negative associations between pregnancy and female age [OR: 0.95, 95% confidence interval (CI): 0.94-0.96], duration of subfertility (OR: 0.99, 95% CI: 0.98-1.00) and basal FSH (OR: 0.94, 95% CI: 0.88-1.00). We found a positive association with number of oocytes (OR 1.04, 95% CI: 1.02-1.07). Better embryo quality was associated with higher pregnancy chances. No significant association was found for the type of infertility and fertilization method. A summary OR for IVF indication and number of embryos transferred could not be calculated, because studies reporting on these used different reference categories. CONCLUSIONS Female age, duration of subfertility, bFSH and number of oocytes, all reflecting ovarian function, are predictors of pregnancy after IVF. Better quality studies are necessary, especially studies that focus on embryo factors that are predictive of success in IVF.

Abstract
OBJECTIVE To investigate the effects of body mass index (BMI) on ovarian stimulation and the outcome of IVF or ICSI treatment in Asian population who have different characteristics of BMI from white people. DESIGN In this retrospective study, the first fresh cycles of 1107 Chinese women were classified by BMI: underweight (BMI <18.5 kg/m(2)), normal weight (BMI: 18.5-23.9 kg/m(2)) and overweight (BMI >or= 24 kg/m(2)). Dose and days of ovarian simulation, cancelled cycles and number of oocytes collected, fertilisation and embryo utilisation rates and pregnancy outcome were compared among BMI groups. RESULTS It showed that overweight women required more ampoules of gonadotrophin (P = 0.002) and had lower peak oestradiol concentration (P = 0.001), increased cycle cancellation due to insufficient follicle development (P = 0.018) and a higher miscarriage rate (10.5 vs. 5.4%, P = 0.018, OR = 2.006 (95% CI: 1.09-3.69, P = 0.025)) compared with normal weight women. However, no differences were found in clinical pregnancy and live-birth rates. Underweight compared with normal weight women showed no differences in ovarian stimulation and IVF outcome although the clinical pregnancy rate was lower (31.1 vs. 37.3%). CONCLUSION At a lower cutoff point of BMI in Chinese women, overweight is associated with increased miscarriage risks and impaired response to ovarian stimulation after IVF and ICSI.

Abstract
BACKGROUND Infertility is a prevalent problem and has significant consequences for individuals, families and the wider community. People's chance of having a healthy, live birth may be impacted upon by factors such as weight, diet, smoking, other substance abuse, environmental pollutants, infections, medical conditions, medications and family medical history. However, there is no current guideline about what preconception advice should be offered to people presenting for infertility treatment. It is important to determine what preconception advice should be given about these types of factors to such people in order to help them to make positive changes and hopefully improve their chances of conception and delivering a healthy, live baby. OBJECTIVES To assess the effects of preconception advice on the chances of a live birth for people who perceive that they may be infertile and are investigating the possibility of medical treatment to address subfertility. SEARCH STRATEGY All published and unpublished randomised controlled trials addressing preconception advice to influence lifestyle factors in people who perceived that they may be infertile and investigated the possibility of medical treatment to address subfertility were sought from the Cochrane Menstrual Disorders and Subfertility Review Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), The Cochrane Library, MEDLINE, PubMed, EMBASE, PsycINFO, AMED, Cumulative Index to Nursing and Allied Health Literature (CINAHL), LILACS, trial registers for ongoing and registered trials, citation indexes, ISI Web of Knowledge, Clinical Study Results database, OpenSIGLE database, China National Knowledge Infrastructure (CNKI) Periodical Index and Google (inception to 5 October 2009). SELECTION CRITERIA Only randomised controlled trials (RCTs), including cluster-randomised (group-randomised) trials, that considered preconception advice given to individuals who perceived that they may be infertile and were investigating the possibility of medical treatment from subfertility specialist services were eligible for inclusion. The primary outcome was live birth, defined as delivery of a live fetus after 20 completed weeks of gestation. DATA COLLECTION AND ANALYSIS Two review authors independently applied eligibility criteria to, extracted data from and assessed the risk of bias in the single included trial. MAIN RESULTS One trial assessing smoking cessation advice for 94 infertile women smokers fulfilled the criteria for this review, but the trial did not report on the review's primary outcome of live birth or any other fertility-related outcomes. This trial of women attending a fertility clinic showed that smoking cessation advice tailored to a woman's "stage-of-change" (readiness to stop smoking) did not show significant evidence of a difference in stage (including smoking cessation rates) compared with standard clinical advice. AUTHORS' CONCLUSIONS No RCTs were located that assessed the effects of preconception advice on the chance of a live birth or other fertility outcomes in people who perceived that they may be infertile and were investigating the possibility of medical treatment to address subfertility. Given the lack of RCTs evaluating the effectiveness of preconception lifestyle advice for people in the afore-mentioned population, this review cannot provide guidance for clinical practice in this area. However, it does highlight the need for further research into this important subject.

Abstract
OBJECTIVE Smoking is a significant health hazard that has been associated with poor reproductive outcome and reduced fertility in reproductive age women. The aim of this study was to assess the effect of nargile smoking on intra-cytoplasmic sperm injection (ICSI) outcome. STUDY DESIGN A prospective analysis of the outcomes of 297 women who underwent ICSI treatment at the ART Unit at the American University of Beirut Medical Center between January 1, and December 31, 2006 was done. The patients were divided into 3 groups based on their smoking status: cigarette smokers (n=42), nargile smokers (n=51) and non-smokers (n=204). RESULTS The mean age of nargile smokers was significantly lower than the other groups; however, the 3 groups were similar with respect to the cause of infertility, total dose of follicular stimulating hormone (FSH), number of oocytes and embryos obtained, and number and quality of embryos transferred. There was no significant difference in the clinical pregnancy rate between nargile smokers and non-smokers (51.0% vs 43.6%). However, cigarette smokers had a significantly lower clinical pregnancy rate compared to non-smokers (23.8% vs 43.6%, p=0.0238). On multiple logistic regression analysis, factors that decreased the clinical pregnancy rates were cigarette smoking and maternal age. CONCLUSION Although this study did not find a deleterious effect of nargile smoking on ICSI outcome, the results need to be confirmed in prospective studies that would include larger number of women with more objective measures of nargile smoke exposure.

Abstract
BACKGROUND Overweight and obesity are an epidemic in Western society, and have a strong impact on fertility. We studied the consequences of overweight and obesity with respect to fecundity, costs of fertility treatment and pregnancy outcome in subfertile women. METHODS We searched the literature for systematic reviews and large studies reporting on the effect of weight on both fecundity and pregnancy outcome in subfertile women. We collected data on costs of treatment with ovulation induction, intrauterine insemination and in vitro fertilization, as well as costs of pregnancy complications. We calculated, for ovulatory and anovulatory women separately, the number of expected pregnancies, complications and costs in a hypothetical cohort of 1000 normal weight, overweight and obese women each. RESULTS In our hypothetical cohort of 1000 women, compared with women with normal weight, live birth was decreased by 14 and 15% (from 806 live births to 692 and 687 live births) in overweight and obese anovulatory women, respectively, for ovulatory women it was decreased by 22 and 24% (from 698 live births to 546 and 531 live births), respectively. These outcomes were associated with an increase in the number of complications and associated costs leading to cost per live birth in anovulatory overweight and obese women were 54 and 100% higher than their normal weight counterparts, for ovulatory women they were 44 and 70% higher, respectively. CONCLUSIONS Overweight and obese subfertile women have a reduced probability of successful fertility treatment and their pregnancies are associated with more complications and higher costs.

Abstract
The FIVCAT. NET database in Catalonia is the only official obligatory registry of human assisted reproduction practitioners in Spain. The present study assessed the effectiveness and outcomes of assisted reproduction over the period 2001-2005 relative to other established worldwide registries. The data analysed were derived from all centres conducting assisted reproduction in Catalonia, and included users of the services (resident and non-resident); all cycles performed; descriptive characteristics of the assisted reproduction procedures; and sociodemographic characteristics of the women. Effectiveness of assisted reproduction was measured by standard indicators such as rates of pregnancy and rates of live births per pregnancy. The results indicated that the preferred number of embryos for transfer changed from three to two over this period. Pregnancies per transfer improved from 33.2% to 37.1% (from 36.9% to 40.2% using fresh embryos and from to 18.4% to 27.0% with frozen embryos). Multiple births decreased from 50.1% to 38.6%, premature births from 37.5% to 28.3% and low-birth-weight infants from 38.0% to 25.6%. It is concluded that the conduct of assisted reproduction in Catalonia has improved considerably and compares favourably with other countries, not only with respect to the level of activity, but also the effectiveness and outcomes achieved, although the quality of the sociodemographic information requires improvement.

Abstract
The increasing miscarriage rate with advancing female age is attributed to a decline in oocyte quality. A poor response to ovarian hyperstimulation is often an expression of a decrease in oocyte quantity. Although oocyte quality and quantity both decrease as a result of ovarian ageing, it is unclear whether these two processes are related to each other. To investigate the relationship between oocyte quantity and quality, we compared miscarriage rates between IVF treated women with a poor and normal response, respectively. Data were studied from a retrospective nationwide cohort of Dutch women undergoing IVF treatment from 1983 to 1995. Women achieving an ongoing pregnancy after their first complete IVF cycle (n=1468) were compared with those experiencing miscarriage (n=357) with respect to their ovarian response. Logistic regression analysis showed a statistically significant association between poor response (fewer than four retrieved oocytes) and miscarriage (P=0.001). Due to interaction, this association became stronger with increasing female age. Among women < 36 years, miscarriage rates between poor and normal responders did not differ, whereas among women 36 years poor responders had a statistically significant increased miscarriage rate compared with normal responders (P=0.001). These results support the hypothesis of a relationship between quantitative ovarian reserve and oocyte quality.
