Abstract
Fertility challenges are a personal and important part of a woman's reproductive health and are associated with health and lifestyle factors. Limited data exist on infertility among women in Palau. We describe the lifetime prevalence of self-reported infertility in a nationally representative sample of women in Palau and investigate the association between tobacco and/or betel nut use and infertility. During May-December 2016, a population-based survey of noncommunicable diseases was conducted in Palau using a geographically stratified random sample of households (N=2409). Men and women ≥18 years of age were chosen randomly from each selected household. The prevalence of a self-reported lifetime episode of infertility (having tried unsuccessfully to become pregnant for ≥12 months) was evaluated among 874 women aged ≥18 years by key health and lifestyle factors. Prevalence ratios (PR) and 95% confidence intervals (CI) were calculated. Of 315 women who ever tried to become pregnant, 39.7% (95% CI: 34.2%, 45.3%) reported a lifetime episode of infertility. Prevalence was higher in women of Palauan vs other ethnicity (PR=1.6, 95% CI: 1.1, 2.3), those who self-reported poor/not good vs. excellent/ very good health status (PR=2.1, 95% CI: 1.4, 3.3), and those with a body mass index (BMI) ≥30 vs <30 (PR=1.7, 95% CI: 1.3, 2.2). Adjusted models showed that tobacco and/or betel nut users were almost twice as likely to report infertility versus non-users (PR=1.8, 95% CI: 1.3, 2.5). More research is needed to understand the infertility experiences of women in Palau and to promote lifestyle factors contributing to optimal reproductive health.

Sexually Dimorphic Response of Increasing Dietary Intake of High Amylose Wheat on Metabolic and Reproductive Outcomes in Male and Female Mice. Nutrients 2019; 12:nu12010061. [PMID: 31881677 PMCID: PMC7019933 DOI: 10.3390/nu12010061] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2019] [Revised: 12/11/2019] [Accepted: 12/18/2019] [Indexed: 02/07/2023] Open
Abstract
High amylose wheat (HAW) has a higher resistant starch content and lower glycaemic index than standard amylose wheat (SAW), which may be associated with health benefits. This study aimed to determine the effects of replacing SAW with HAW on metabolic and reproductive parameters in male and female mice. Male and female C57BL/6 mice were randomly divided into groups (n = 8/group/sex) and fed either a SAW65 (65% SAW w/w; control), HAW35 (35% HAW w/w), HAW50 (50% HAW w/w) or HAW65 (65% HAW w/w) diet for eight weeks. In male but not female, the HAW65 group had a lower abdominal circumference, relative total fat mass, relative gonadal fat mass and plasma leptin concentration compared to the HAW35 group. There were no differences in fasting blood glucose concentrations or plasma concentrations of cholesterol, triglycerides or non-esterified fatty acids between groups in either males or females. The HAW-fed males had a higher testicular weight and HAW-fed females spent less time in diestrus and a longer time in metestrus compared to the SAW-fed mice. Higher dietary intake of HAW appears to reduce abdominal fat deposition compared to the lower level of HAW in a sexually dimorphic manner. The impacts on reproductive parameters in the HAW-fed mice require further investigation.

Abstract
PURPOSE University students happen to be in a transitional period at the beginning of one's adult life and thereby establish the basis for their health care. The negative lifestyles followed by students during this period can also affect their reproductive health. The purpose of this study was to identify lifestyle, reproductive health, gender differences and relationships between lifestyle and reproductive health in university students. METHODS We used a descriptive cross-sectional design. A total of 300 subjects were enrolled. Data were collected using structured questionnaires between October 11 and 25, 2017 and analyzed using SPSS 25.0. Subjects agreed to undergo a face-to-face interview, including administration of the Health Promotion Lifestyle Profile II (HPLP-II) and reproductive health (knowledge, attitude, and behaviors). RESULTS The mean age of the subjects was 21.4 years. HPLP-II and reproductive health behaviors were significantly different between the genders. The scores of physical activity and nutrition in females were significantly lower than males. The scores of safe sex and sexual responsibility in females were significantly higher than males, and the score of genital health management was significantly lower in females than males. High HPLP-II score was observed to be in correlation with high reproductive health attitudes and behaviors. CONCLUSION The result revealed differences in lifestyle and reproductive health between both the genders. For improvement of reproductive health of university students, provision of lifestyle intervention including healthy nutritional habits and physical activity is imperative.

Cannabis consumption might exert deleterious effects on sperm nuclear quality in infertile men. Reprod Biomed Online 2019; 40:270-280.

Abstract
RESEARCH QUESTION Can cannabis consumption alter sperm nuclear integrity in infertile men? DESIGN A retrospective cross-sectional study conducted between July 2003 and December 2013, which included 54 men who consulted for male-factor infertility. Twenty-seven infertile men who were regular cannabis users were matched to 27 infertile men who were cannabis non-users. To complement the conventional semen parameter and plasma hormone level assessments, sperm nuclear alterations were explored using fluorescence in-situ hybridization to assess numerical chromosomal abnormalities, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling to investigate DNA fragmentation, aniline blue staining to examine chromatin condensation and a motile sperm organelle morphology examination to detect vacuoles in sperm heads. RESULTS The rates of sperm aneuploidy (P = 0.0044), diploidy (P = 0.037), total chromosome abnormalities (P = 0.0027) and DNA fragmentation (P = 0.027) were significantly higher in cannabis users than in non-cannabis users. CONCLUSIONS Cannabis consumption might have deleterious effects on sperm nuclear quality in infertile men by increasing numerical chromosome abnormalities and DNA fragmentation. Cannabis consumption induces these detrimental effects on the progression of spermatogenesis from meiotic stages to spermiogenesis and potentially on post-testicular sperm maturation in infertile men. Any potential findings, however, need to be validated with larger sample size, and our data are only exploratory findings.

Abstract
Context With the increase of obesity, it is imperative to understand the neuroendocrine mechanisms, including the neuroendocrine hormone leptin, by which obese or overweight women are at increased risk for subfertility and infertility. Objective The objective was to examine associations between preconception serum leptin concentrations, fecundability, pregnancy, and live birth. Design Secondary analysis of a prospective cohort among women with prior pregnancy losses. Setting The study was conducted at four US medical centers (2006 to 2012). Intervention Not available. Materials and Methods Preconception serum leptin concentrations were measured at baseline, and women were followed for up to six menstrual cycles, and throughout pregnancy if they conceived. Discrete Cox proportional hazard regression models were used to assess fecundability odds ratios (FORs) and log-binomial regression to estimate risk ratios (RRs) for pregnancy and live birth. Models were adjusted for age, physical activity, treatment arm, and adiposity, either by measured waist-to-hip ratio or body mass index (BMI). Results High leptin concentrations were associated with decreased fecundability (FOR 0.72, 95% CI 0.58, 0.90), reduced risk of pregnancy (RR 0.87, 95% CI 0.78, 0.96) and live birth (RR 0.76, 95% CI 0.65, 0.89) comparing the upper to the lower tertile. However, adjustment for BMI in lieu of waist-to-hip ratio nullified observed associations. Conclusions In women with a history of pregnancy loss, relations between higher preconception leptin and fecundability were attenuated after adjustment for BMI, although not after adjustment for other markers of adiposity. Leptin may serve as a complementary marker of adiposity for assessment of obesity and reproductive outcomes.

Abstract
BACKGROUND Bisphenol S (BPS) was introduced in the market as a potentially safer alternative to bisphenol A (BPA). However, there are limited studies on health effects of BPS and no epidemiologic studies on its relationship with male reproductive health outcomes, specifically semen quality. OBJECTIVE To investigate predictors of urinary BPS concentrations and its association with semen parameters among men attending a fertility center. METHODS This cross-sectional analysis included 158 men of couples seeking fertility treatment (2011-2017) contributing 338 paired semen and urine samples. At the time of sample collection, men completed a questionnaire on self-reported use of household products and food intake within the previous 24 h. Urinary concentrations of BPA, BPS and bisphenol F were quantified using isotope-dilution tandem mass spectrometry. Semen samples were analyzed following WHO guidelines. Multivariable mixed models were used to investigate predictors of urinary BPS concentrations and to evaluate associations between urinary BPS concentrations and semen parameters, using random intercept to account for correlation in outcomes across multiple observations per man and adjusting for abstinence time, specific gravity, age, body mass index (BMI), year of sample collection and BPA concentrations. Analyses were also stratified by BMI (≥25 vs <25 kg/m2). RESULTS Median (IQR) urinary BPS concentration was 0.30 (0.20, 0.90) μg/L, and 76% of samples had detectable (>0.1 μg/L) concentrations. Self-reported fabric softener and paint/solvent use as well as intake of beef and cheese within 24 h before urine collection were positively associated with BPS concentrations. Men with higher BPS concentrations also had significantly higher BMI. Lower semen parameters were found among men with detectable BPS concentrations, compared to men with non-detectable BPS [2.66 vs. 2.91 mL for volume (p = 0.03), 30.7 vs. 38.3 mil/mL for concentration (p = 0.03), 76.8 vs. 90.0 mil for total count (p = 0.09), 43.7 vs. 47.0% for motility (p = 0.06), and 5.42 vs. 6.77% for morphologically normal sperm (p = 0.24)]. Some associations of BPS with lower semen parameters were only found among men with a BMI ≥ 25 kg/m2. CONCLUSIONS We identified dietary and lifestyle factors associated with BPS exposure, suggesting potential avenues for reducing exposures. We also observed negative associations between BPS and semen parameters, especially among overweight and obese men.

Abstract
Despite advances in the field of male reproductive health, idiopathic male infertility, in which a man has altered semen characteristics without an identifiable cause and there is no female factor infertility, remains a challenging condition to diagnose and manage. Increasing evidence suggests that oxidative stress (OS) plays an independent role in the etiology of male infertility, with 30% to 80% of infertile men having elevated seminal reactive oxygen species levels. OS can negatively affect fertility via a number of pathways, including interference with capacitation and possible damage to sperm membrane and DNA, which may impair the sperm's potential to fertilize an egg and develop into a healthy embryo. Adequate evaluation of male reproductive potential should therefore include an assessment of sperm OS. We propose the term Male Oxidative Stress Infertility, or MOSI, as a novel descriptor for infertile men with abnormal semen characteristics and OS, including many patients who were previously classified as having idiopathic male infertility. Oxidation-reduction potential (ORP) can be a useful clinical biomarker for the classification of MOSI, as it takes into account the levels of both oxidants and reductants (antioxidants). Current treatment protocols for OS, including the use of antioxidants, are not evidence-based and have the potential for complications and increased healthcare-related expenditures. Utilizing an easy, reproducible, and cost-effective test to measure ORP may provide a more targeted, reliable approach for administering antioxidant therapy while minimizing the risk of antioxidant overdose. With the increasing awareness and understanding of MOSI as a distinct male infertility diagnosis, future research endeavors can facilitate the development of evidence-based treatments that target its underlying cause.

Sodium nitrite negatively affects reproductive ability and offspring survival in female mice. Toxicology 2019; 427:152284. [PMID: 31476334 DOI: 10.1016/j.tox.2019.152284] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2019] [Revised: 08/26/2019] [Accepted: 08/29/2019] [Indexed: 12/12/2022]
Abstract
Sodium nitrite (NaNO2) is an industrial chemical that is frequently used as a food additive to prevent botulism and enhance glossiness, such as curing meat. In addition, in some regions, water source NaNO2 concentrations exceed standard regulatory levels. Whether the excessive intake of NaNO2 has toxic effects on female fertility and fetal development remain unknown. In this study, we administered ICR mice control saline, low-dose NaNO2 (60 mg/kg/day), or high-dose NaNO2 (120 mg/kg/day) by intragastric gavage for 21 days. We then assessed oocyte morphology, spindle-chromosome dynamics, mitochondrial distribution, ATP content, apoptotic cell numbers, DNA damage levels, histone modifications, reactive oxygen species (ROS) levels, and offspring survival. Results showed that NaNO2 treatment decreased oocyte number, impaired polar body extrusion, and increased zona pellucida thickness in oocytes. Furthermore, NaNO2 disrupted MII spindle integrity, caused abnormal mitochondrial distribution, decreased ATP content, and increased levels of ROS and H3K4me2. Moreover, the number of oocytes in early stages of apoptosis and with levels of DNA damage increased in NaNO2-treated mice along with decreased offspring numbers and survival rates. We demonstrated the negative effects of NaNO2 on female reproductive abilities in mice.

Association of frequency of television watching with overweight and obesity among women of reproductive age in India: Evidence from a nationally representative study. PLoS One 2019; 14:e0221758. [PMID: 31465465 PMCID: PMC6715273 DOI: 10.1371/journal.pone.0221758] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2019] [Accepted: 08/14/2019] [Indexed: 01/22/2023] Open
Abstract
Background For women of reproductive age, overweight and obesity are an established risk factor for several medical complications. To address the increasing rate of obesity in India through public health awareness programs, the association between common behaviors and overweight and obesity needs to be investigated. This study aims to determine whether there is any association between the frequency of television watching and overweight and obesity among women of reproductive age (15–49 years) in India. Methods This is a cross-sectional study that utilized data from the National Family Health Survey (NFHS-4), which utilized a nationally representative sample from all 29 states and 7 union territories of India. The survey itself followed a two-staged stratified random sampling technique. The primary outcome of interest was overweight (23.0 kg/m2 to <27.5 kg/m2) and obesity (≥27.5 kg/m2), measured by using the Asian body mass index cut-off. The major explanatory variable was the frequency of television watching, measured in days per week. Sample weight of NFHS-4 was adjusted during the analysis. Multilevel ordered logistic regression was conducted to identify the factors associated with overweight and obesity. To show the strength of association, both the unadjusted Crude Odds Ratio (COR) and the Adjusted Odds Ratio (AOR) were reported with a 95% confidence interval (CI). A p-value<0.05 was considered statistically significant. Results The analysis included weighted data from 644,006 Indian women of reproductive age (15–49 years). Among the respondents, 33.5% were overweight or obese (BMI ≥23.0 kg/m2). The prevalence of overweight and obesity increased with age (p-value <0.0001) and almost half of the women aged 35–49 years were either overweight or obese (48.6%). The prevalence was significantly higher among those living in an urban area compared to a rural area (urban 46.5% vs. rural 26.5%; p-value <0.001). The prevalence of overweight and obesity increased with the frequency of watching television and was the highest among the individuals who reported watching television almost every day (p-value <0.0001). Women watching television almost every day had 24% (AOR: 1.24, 95% CI: 1.21–1.26; p-value <0.001) increased odds of being overweight and obese compared to their counterparts who never watched television. Conclusions This study found that the likelihood of being overweight and obese significantly increased with the frequency of watching television; likely due to physical inactivity during leisure time. Further studies should examine the physical activity and food habits of this target group. Public health promotion programs in India should raise awareness regarding the harmful effects of the sedentary lifestyle associated with watching television.

Urinary concentrations of benzophenone-3 and reproductive outcomes among women undergoing infertility treatment with assisted reproductive technologies. THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 678:390-398. [PMID: 31077917 PMCID: PMC6550292 DOI: 10.1016/j.scitotenv.2019.04.452] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2018] [Revised: 04/30/2019] [Accepted: 04/30/2019] [Indexed: 05/20/2023]
Abstract
Benzophenone-3 is used in a variety of cosmetic products as a sunscreen, and has shown weak estrogenic and antiandrogenic activity in animal and in vitro studies. Few studies have evaluated whether benzophenone-3 is associated with reproductive outcomes among women. We studied 304 women undergoing infertility treatment (2007-2017) in the prospective Environment and Reproductive Health cohort study and who underwent 449 treatment cycles (n = 788 urines). Generalized linear mixed models were used with random intercepts to account for multiple cycles, and adjusting for confounders including physical activity. Analyses were also stratified by self-reported moderate/heavy outdoor work. The cycle-specific median (IQR) urinary benzophenone-3 concentration was 147 (58, 462) μg/L, and 98% samples had detectable concentrations. Self-reported sunscreen use, physical activity, and time spent on moderate/heavy outdoor work were positively associated with urinary benzophenone-3. Adjusted probabilities of implantation, clinical pregnancy and live birth were higher in increasing quartiles of benzophenone-3, but these associations were restricted to women who reported spending time outdoors performing moderate/heavy work. Specifically, among these women, those in the highest quartile of benzophenone-3 concentrations had 51% higher implantation (p,trend = 0.02), 68% higher clinical pregnancy (p,trend = 0.01) and 75% higher live birth (p,trend = 0.02) adjusted probabilities than women in the lowest quartile. Benzophenone-3 was unrelated to these outcomes among women who did not report doing moderate/heavy work outdoors. These results confirm that sunscreen use is a source of benzophenone-3 exposure, and show positive associations between benzophenone-3 and pregnancy outcomes, especially among women who reported engaging in outdoor work. Since these associations may be subject to important residual confounding by lifestyle factors, further research is needed to confirm these novel results in other populations, and to investigate whether other factors may be affecting the relation of benzophenone-3 with fertility and other health outcomes.

Abstract
Strong evidence suggests that sexual behavior and reproductive success can be predicted by personality traits. Here, I review new studies that have contributed to the understanding of these associations and outline potential avenues for further research. Findings show that extraversion is the most important personality trait in sexual behavior (number of lifetime sexual partners, involvement in casual sex, marital infidelity, condom use, male and female sexual dysfunction, sexual coercion, and sexual harassment) and that neuroticism, agreeableness, and conscientiousness are also associated with these outcomes. Extraversion has emerged as the most important personality trait for fertility in men but appears relatively unimportant for fertility in women. Findings for other personality traits are somewhat mixed, probably because of variations in research design, and further prospective studies are recommended to address potential bidirectional associations. Further research is also needed in adolescent samples, in understudied topic areas (e.g., sexually transmitted infections, biomarkers of fertility), and on personality similarity between sexual partners in samples from both poor and developed nations.

Abstract
Alcohol exposure during pregnancy results in impaired growth, stillbirth, and fetal alcohol spectrum disorder. Fetal alcohol deficits are lifelong issues with no current treatment or established diagnostic or therapeutic tools to prevent and/or ameliorate some of these adverse outcomes. Despite the recommendation to abstain, almost half of the women consume alcohol in pregnancy in the United States. This review focuses on the trends in prenatal alcohol exposure, implications for maternal and fetal health, and evidence suggesting that preconception and the prenatal period provide a window of opportunity to intervene, mitigate, and ideally curtail the lifetime effects of fetal alcohol spectrum disorder.

Abstract
Consumption of unhealthy, energy-dense palatable food during early age leads to obesity in children and the onset of obesity during childhood has a profound effect on the reproductive health of women. In this study, the mechanism underlying diet-induced obesity on ovarian dysfunction was studied by exposing rats to cafeteria diet (CAFD) for two different durations. For that purpose, 21-day-old female Sprague Dawley rats were fed ad libitum with a standard diet (control group) and a cafeteria diet (CAFD group) for a period of 20 weeks (20 W) and 32 weeks (32 W). We observed obesity, hyperglycemia, hyperlipidemia, hyperleptinemia and hypoadiponectinemia in CAFD fed groups. Hyperinsulinemia, hypergonadotrophism, hypertestosteronemia and hyperprogesteronemia were observed in the 20 W-CAFD group. Conversely, in the 32 W-CAFD group hypersecretion declined to hyposecretion. The levels of estradiol remained low during both time periods. The duration of estrous cycle was extended in the CAFD fed rats. The ovary weight was higher in the 20 W-CAFD fed rats but it was drastically reduced over a longer duration cafeteria diet feeding. In the 20 W-CAFD fed rats, the protein levels of LHR, StAR, CYP11A1, 3β-HSD and 17β-HSD were increased but FSHR and CYP19A1 levels were decreased in the ovary. On the other hand, gonadotropin receptor and the protein levels of steroidogenic enzymes were decreased in the ovary of 32 W-CAFD fed rats. We conclude that the duration of energy-dense diet consumption has differential regulatory mechanism in altering the ovarian steroid production. In 20 W-CAFD fed rats, hypergonadotropic condition was observed whereas, 32 W-CAFD consumption induced hypogonadotropic hypogonadism.

Abstract
OBJECTIVE Dietary quality (DQ), as assessed by the Alternative Healthy Eating Index for Pregnancy (AHEI-P), and conception and pregnancy outcomes were evaluated. DESIGN In this prospective cohort study on couples planning their first pregnancy. Cox proportional hazards regression assessed the relationship between AHEI-P score and clinical pregnancy, live birth and pregnancy loss. SETTING Participants were recruited from the Northeast region of the USA.Participants: Healthy, nulliparous couples (females, n 132; males, n 131; one male did not enrol). RESULTS There were eighty clinical pregnancies, of which sixty-nine resulted in live births and eleven were pregnancy losses. Mean (sd) female AHEI-P was 71·0 (13·7). Of those who achieved pregnancy, those in the highest tertile of AHEI-P had the greatest proportion of clinical pregnancies; however, this association was not statistically significant (P = 0·41). When the time it took to conceive was considered, females with the highest AHEI-P scores were 20 % and 14 % more likely to achieve clinical pregnancy (model 1: hazard ratio (HR) = 1·20; 95 % CI 0·66, 2·17) and live birth (model 1: HR = 1·14; 95 % CI 0·59, 2·20), respectively. Likelihood of achieving clinical pregnancy and live birth increased when the fully adjusted model, including male AHEI-P score, was examined (clinical pregnancy model 4: HR = 1·55; 95 % CI 0·71, 3·39; live birth model 4: HR = 1·36; 95 % CI 0·59, 3·13). CONCLUSIONS The present study is the first to examine AHEI-P score and achievement of clinical pregnancy. DQ was not significantly related to pregnancy outcomes, even after adjustments for covariates.

Urinary concentrations of bisphenol A, parabens and phthalate metabolite mixtures in relation to reproductive success among women undergoing in vitro fertilization. ENVIRONMENT INTERNATIONAL 2019; 126:355-362. [PMID: 30826614 PMCID: PMC6469504 DOI: 10.1016/j.envint.2019.02.025] [Citation(s) in RCA: 64] [Impact Index Per Article: 12.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/14/2018] [Revised: 02/04/2019] [Accepted: 02/10/2019] [Indexed: 05/19/2023]
Abstract
BACKGROUND We have previously investigated whether urinary concentrations of bisphenol A (BPA), parabens, and phthalate metabolites were individually associated with reproductive outcomes among women undergoing in vitro fertilization (IVF) treatment. However, humans are typically exposed to many man-made chemicals simultaneously. Thus, investigating one chemical at a time may not represent the effect of mixtures. OBJECTIVE To investigate whether urinary concentrations of BPA, parabens, and phthalate metabolite mixtures are associated with reproductive outcomes among women undergoing IVF. METHODS This prospective cohort study included 420 women contributing 648 IVF cycles who provided up to two urine samples per cycle prior to oocyte retrieval (N = 1145) between 2006 and 2017 at the Massachusetts General Hospital Fertility Center, and had available urine biomarker data. Urinary concentrations of BPA, parabens, and phthalate metabolites were quantified using isotope-dilution tandem mass spectrometry. Intermediate and clinical end-points of IVF treatments were abstracted from electronic medical records. Principal component analysis (PCA) and Bayesian kernel machine regression (BKMR) were used to identify main patterns of BPA, parabens, and phthalate metabolites concentrations. We used generalized linear mixed models to evaluate the association between PCA-derived factor scores, in quartiles, and IVF outcomes, using random intercepts to account for multiple IVF cycles and adjusting for known confounders. Because of temporal trends in exposure, we conducted a sensitivity analysis restricted to women who underwent IVF cycles in the earlier years of study (2006-2012). RESULTS Urinary concentrations of BPA, parabens, and most phthalate metabolites were significantly lower during the second half of the study period (2013-2017) than during the first half (2006-2012). None of the three factors derived from the PCA [di(2-ethylhexyl) phthalate (DEHP), non-DEHP, and paraben] was associated with IVF outcomes in the main analyses. Similarly, BKRM analyses did not identify any associations of individual urinary concentrations of BPA, paraben and phthalate metabolites with IVF outcomes while accounting for correlation between exposures. However, in sensitivity analyses restricted to women who underwent IVF cycles from 2006 to 2012, where concentrations of most phthalates and phenols were higher, there were decreases in implantation, clinical pregnancy, and live birth across quartiles of the DEHP factor. Specifically, women in the highest quartile of the DEHP factor had, on average, lower probabilities of implantation (-22% p, trend = 0.08), clinical pregnancy (-24% p, trend = 0.14), and live birth (-38% p, trend = 0.06) compared to women in the lowest quartile. Among this group of women, BKMR results did not identify any single contributor driving the decreased probabilities of live birth within the DEHP factor. CONCLUSIONS We confirmed that women undergoing IVF are concurrently exposed to multiple endocrine disrupting chemicals (EDCs). While we found no overall significant associations, we observed diminished pregnancy success with specific clusters of chemicals among women who underwent IVF cycles in earlier years of study, when urinary concentrations of these EDCs were higher.

Abstract
OBJECTIVE The aim of this study was to assess whether luteinising hormone (LH) surge characteristics influenced the likelihood of conceiving naturally. METHODS This was a single-cycle, home-based, observational, case-controlled study. Volunteers collected daily urine samples for one menstrual cycle. LH was measured and the basal levels, surge day, peak day, peak concentration and magnitude of LH surges were examined. Predictive models using sociodemographic data, LH surge characteristics, and sociodemographic data combined with LH profile properties, were evaluated. RESULTS The surge profile did not differ between cycles with early or late ovulation and was not affected by age or body mass index (BMI). The mean LH surge day was day 16 for both groups. Mean LH surge and concentrations did not differ between groups (surge concentration 54.8 IU/l vs. 58.2 IU/l and peak concentration 82.0 IU/l vs. 81.6 IU/l for pregnant vs. non-pregnant volunteers, respectively). Non-pregnant volunteers were more likely, however, to have a raised or a reduced basal LH on day 6 or have an atypical LH profile. Sociodemographic characteristics were significant predictors of pregnancy, and sociodemographic variable-based models had the greatest predictive ability for conception, providing up to 65% predictive accuracy. CONCLUSIONS Sociodemographic variables can be used to predict the likelihood of a woman conceiving naturally. Provided an LH surge is present, its profile does not relate to the likelihood of spontaneous pregnancy. The conception rate was significantly lower, however, in women with elevated or reduced basal levels of LH, suggesting that follicular maturation needs an optimal basal level of LH in natural conception cycles.

Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the gastrointestinal tract that is usually diagnosed in young individuals. Crohn's disease and ulcerative colitis are the 2 principal forms of IBD. Patients with IBD demonstrate varying degrees of disease activity and sometimes need to undergo bowel surgery such as proctocolectomy with ileal pouch-anal anastomosis that involves removal of the entire colon and rectum with consequent sexual dysfunction. Several studies have shown that sulfasalazine, affects male fertility. Additionally, many men with IBD are unable to control their smoking, drinking, and eating habits, which can cause worsening of disease activity and fertility. Therefore, infertility and sexual dysfunction are important issues in young patients diagnosed with IBD because they are related to optimal management of the disease and patients' quality of life. Only a few studies have reported sexual dysfunction and infertility in men with IBD. Therefore, this study reviewed the current literature describing male sexual dysfunction scales and evaluated the causes of sexual dysfunction and infertility in men with IBD.

Abstract
Assisted reproductive techniques including in vitro fertilization (IVF) are being used increasingly worldwide and screening for genital tract infections (GTIs) is recommended prior to treatment as their presence may affect the success rate of IVF. The current study aimed to assess the possible associations between GTI-associated factors and reproductive outcome in a group of reproductive age fertile females and infertile females receiving IVF. A total of 111 infertile women enrolled in an IVF programme (Group A) and 104 fertile women (mothers of at least one child; Group B) underwent microbiological screening of vaginal and cervical samples. All samples were cultured using different protocols for aerobic pathogens, bacterial vaginosis (BV), Ureaplasma urealyticum, Mycoplasma hominis, Chlamydia trachomatis and human papilloma virus (HPV). Although each group were comparable in age, more infertile women were >30 years (P=0.0064), had a higher education level (P=0.0001) and were smokers (P=0.007). Only BV (P=0.0013) was more prevalent in Group A. Of the 111 infertile females who were scheduled for IVF, 32 females had a successful pregnancy (Group C) and 79 females exhibited IVF failure (Group D). Tubal factor (P=0.012), estradiol-2 (E2) levels <2,500 pg/ml (P=0.0009) and Mycoplasma infection (P=0.003) were identified to be the strongest predictors of IVF failure. The current study determined certain GTI-associated factors that may contribute to infertility in Greek females of reproductive age as well as other risk factors associated with failure in patients undergoing IVF. Further studies are required to confirm this conclusion.

Abstract
OBJECTIVE: To assess the prevalence of successful assisted reproductive technology and to identify the associated factors. METHODS: This population-based birth cohort study was carried out with 4,333 pregnant women expected to deliver in 2015 in the urban area of Pelotas, Southern Brazil. Use of an assisted reproductive technology procedure, type of assisted reproductive technology [in vitro fertilization or intracytoplasmic sperm injection or artificial insemination], number of embryos transferred, success of embryo transfer, number of attempts, and reported reasons for seeking assisted reproductive technology were the main outcomes measured. Use of an assisted reproductive technology procedure was analyzed according to sociodemographic, nutritional, reproductive history, and behavioral characteristics. Unadjusted and adjusted analyses were performed by logistic regression. RESULTS: Among the 4,275 newborns enrolled in the Pelotas 2015 Birth Cohort Study, 18 births (0.4%) were conceived by assisted reproductive technology. Most cases of assisted reproductive technology were by in vitro fertilization (70.6%). All cycles were performed in private clinics under direct out-of-pocket payment. Even after controlling for confounders, maternal age > 35 years, nulliparity and high family monthly income were strongly associated with assisted reproductive technology. CONCLUSIONS: The use of assisted reproductive technology services was reported by only a few women in the Pelotas 2015 Birth Cohort Study. Our study highlights sociodemographic factors associated to assisted reproductive technology procedures. To better understand the patterns and barriers in overall use of assisted reproductive technology services over time, national-level trend studies in assisted reproductive technology treatments and outcomes, as well as studies exploring the characteristics of women who have sought this kind of treatment are needed in low-middle income countries.

Abstract
Stress is deeply rooted in the modern society due to limited resources and large competition to achieve the desired goal. Women are more frequently exposed to several stressors during their reproductive age that trigger generation of reactive oxygen species (ROS). Accumulation of ROS in the body causes oxidative stress (OS) and adversely affects ovarian functions. The increased OS triggers various cell death pathways in the ovary. Beside apoptosis and autophagy, OS trigger necroptosis in granulosa cell as well as in follicular oocyte. The OS could activate receptor interacting protein kinase-1(RIPK1), receptor interacting protein kinase-3 (RIPK3) and mixed lineage kinase domain-like protein (MLKL) to trigger necroptosis in mammalian ovary. The granulosa cell necroptosis may deprive follicular oocyte from nutrients, growth factors and survival factors. Under these conditions, oocyte becomes more susceptible towards OS-mediated necroptosis in the follicular oocytes. Induction of necroptosis in encircling granulosa cell and oocyte may lead to follicular atresia. Indeed, follicular atresia is one of the major events responsible for the elimination of majority of germ cells from cohort of ovary. Thus, the inhibition of necroptosis could prevent precautious germ cell depletion from ovary that may cause reproductive senescence and early menopause in several mammalian species including human.

Abstract
OBJECTIVE There is some evidence that personality relates to childbearing in adulthood but the importance of personality for reproductive capacity is unknown. This study explored cross-time associations between the major dimensions of trait personality and self-reported fertility and fecundity. METHODS A representative sample of young Australian adults [n = 4501; age range ≈ 18-44 (women), 18-54 (men)] provided information on personality, fertility, fertility intentions, fecundity and lifestyle factors (cigarette smoking, alcohol consumption, physical activity) in 2006 and again in 2016. Older Australian adults [n = 4359; age ≥ 45 (women), ≥ 55 (men)] provided information on personality, lifestyle factors and completed fertility. RESULTS After controlling for sociodemographic factors, completed fertility was associated with higher agreeableness in both sexes, and lower conscientiousness and openness in women. In younger adults, higher levels of openness were associated with fewer children 10 years later in both sexes, and higher extraversion was associated with more children 10 years later in men. The association between fertility intentions and subsequent fertility was stronger among women scoring higher on conscientiousness, and women scoring higher on neuroticism were more likely to acquire medical or health difficulties in having children - an effect that was mediated by higher levels of cigarette smoking. CONCLUSIONS The study provides initial evidence for an association between personality and the acquisition of difficulties in having children.

Abstract
BACKGROUND Exposure to non-persistent chemicals in consumer products is ubiquitous and associated with endocrine-disrupting effects. These effects have been linked to infertility and adverse pregnancy outcomes in some studies and could affect couple fecundability, i.e. the capacity to conceive a pregnancy, quantified as time to pregnancy (TTP). OBJECTIVE AND RATIONALE Few epidemiologic studies have examined the impact of non-persistent chemicals specifically on TTP, and the results of these studies have not been synthesized. We undertook a systematic review to summarize the strength of evidence for associations of common non-persistent chemicals with couple fecundability and to identify gaps and limitations in the literature, with the aim of informing policy decisions and future research. SEARCH METHODS We performed an electronic search of English language literature published between 1 January 2007 and 25 August 2017 in MEDLINE, EMBASE.com, Global Health, DART/TOXLINE, POPLINE and DESTAF. We included human retrospective and prospective cohort, cross-sectional and case-control studies that examined phthalates, bisphenol A, triclosan, triclocarban, benzophenones, parabens and glycol ethers in consumer products, and considered TTP or fecundability as an outcome among women, men and couples conceiving without medical assistance. We excluded editorials, opinion pieces, introductions to special sections, articles that described only lifestyle (e.g. caffeine, stress) or clinical factors (e.g. semen parameters, IVF success). Standardized forms for screening, data extraction and study quality were developed using DistillerSR software and completed in duplicate. We used the Newcastle-Ottawa Scale to assess risk of bias and devised additional quality metrics based on specific methodological features of fecundability studies. OUTCOMES The search returned 3456 articles. There were 15 papers from 12 studies which met inclusion criteria, of which eight included biomarkers of chemical exposure. Studies varied widely in terms of exposure characterization, precluding a meta-analytic approach. Among the studies that measured exposure using biospecimens, results were equivocal for associations between either male or female phthalate exposure and TTP. There was preliminary support for associations of female exposure to some parabens and glycol ethers and of male exposure to benzophenone with longer TTP, but further research and replication of these results are needed. The results provided little to no indication that bisphenol A, triclocarban or triclosan exposure was associated with TTP. WIDER IMPLICATIONS Despite a growing literature on couple exposure to non-persistent endocrine-disrupting chemicals and fecundability, evidence for associations between biologically measured exposures and TTP is limited. Equivocal results with different non-persistent chemical compounds and metabolites complicate the interpretation of our findings with respect to TTP, but do not preclude action, given the documented endocrine disrupting effects on other reproductive outcomes as well as fetal development. We therefore advocate for common-sense lifestyle changes in which both females and males seeking to conceive minimize their exposure to non-persistent chemicals. SYSTEMATIC REVIEW REGISTRATION NUMBER CRD42018084304.

Abstract
Sertoli cells are somatic cells present in seminiferous tubules which have essential roles in regulating spermatogenesis. Considering that each Sertoli cell is able to support a limited number of germ cells, the final number of Sertoli cells reached during the proliferative period determines sperm production capacity. Only immature Sertoli cells, which have not established the blood-testis barrier, proliferate. A number of hormonal cues regulate Sertoli cell proliferation. Among them, FSH, the insulin family of growth factors, activin, and cytokines action must be highlighted. It has been demonstrated that cAMP/PKA, ERK1/2, PI3K/Akt, and mTORC1/p70SK6 pathways are the main signal transduction pathways involved in Sertoli cell proliferation. Additionally, c-Myc and hypoxia inducible factor are transcription factors which participate in the induction by FSH of various genes of relevance in cell cycle progression. Cessation of proliferation is a pre-requisite to Sertoli cell maturation accompanied by the establishment of the blood-testis barrier. With respect to this barrier, the participation of androgens, estrogens, thyroid hormones, retinoic acid and opioids has been reported. Additionally, two central enzymes that are involved in sensing cell energy status have been associated with the suppression of Sertoli cell proliferation, namely AMPK and Sirtuin 1 (SIRT1). Among the molecular mechanisms involved in the cessation of proliferation and in the maturation of Sertoli cells, it is worth mentioning the up-regulation of the cell cycle inhibitors p21Cip1, p27Kip, and p19INK4, and of the gap junction protein connexin 43. A decrease in Sertoli cell proliferation due to administration of certain therapeutic drugs and exposure to xenobiotic agents before puberty has been experimentally demonstrated. This review focuses on the hormones, locally produced factors, signal transduction pathways, and molecular mechanisms controlling Sertoli cell proliferation and maturation. The comprehension of how the final number of Sertoli cells in adulthood is established constitutes a pre-requisite to understand the underlying causes responsible for the progressive decrease in sperm production that has been observed during the last 50 years in humans.

Abstract
To examine the effect of serum follicle-stimulating hormone (sFSH) level, body-mass index (BMI) and smoking on Testicular Sperm Extraction-Intracytoplasmic Sperm Injection (TESE-ICSI), and pregnancy outcomes.In this retrospective study, data were extracted from files of 52 azoospermic men who underwent TESE and in-vitro fertilization (IVF)-ICSI in our IVF unit. Demographic information, treatment cycle follow-up and pregnancy outcomes were collected.Fifty-two patients underwent 79 TESE due to azoospermia in 143 IVF cycles. Smoking was found to significantly affect sperm motility in TESE specimens before freezing (45.5% vs 14.8%; P <.001); however, this finding did not influence the pregnancy rate. Male FSH was inversely correlated with testicle volume (r = -0.595, P <.0001). Body weight did not affect semen parameters after TESE or ICSI outcomes.Among azoospermic patients with extremely poor sperm quality, male BMI, male FSH or smoking did not have an adverse effect sperm parameters or pregnancy and delivery rates.

Abstract
OBJECTIVES The objective of our manuscript is to review the current state of research on the genetics of male infertility, highlighting the genetic abnormalities that can lead to non-syndromic male infertility and genetic testing proposed to patients. It is intended primarily for clinicians and biologists of reproductive medicine. METHODS A comprehensive review of the scientific literature available on PubMed was conducted using keywords related to male infertility and genetics. Since the first genes related to non-syndromic male infertility were identified after the 2000s, bibliographic research was conducted after this date. RESULTS Thirty-three genes have been identified as responsible for non-syndromic male infertility. The evolution of techniques based on whole genome analysis has allowed the development of more successful methods in the identification of new genes and mutations inducing an infertility phenotype. Through this article, we propose, by concrete examples, a clinical approach for genetic tests considering the semen analysis alterations. CONCLUSIONS The identification and characterization of these genes and the mutations responsible for certain infertility phenotypes allow better management and better treatment for patients as well as a better understanding of the physiopathological mechanisms of human gametogenesis.

Abstract
BACKGROUND Many men have limited knowledge about reproductive health and fertility. The aim of the study was to evaluate if Reproductive Life Plan (RLP)-based counselling during a sexual health visit could increase men's fertility awareness. MATERIAL AND METHODS The study was a randomized controlled trial including 201 men aged 18-50 who visited either of two participating sexual health clinics in Sweden for sexually transmitted infection testing during 2014-2016. All men received standard care, and men in the intervention group (IG) also received oral and written RLP-based information about lifestyle and fertility. Awareness about fertility and lifestyle-related factors were the main outcomes, measured through a questionnaire before the intervention and through a telephone survey after three months. Impressions from the counselling were also assessed at follow-up. RESULTS A majority (71%) of men wanted children in the future. General fertility awareness increased from a mean score of 4.6 to 5.5 out of 12 (P = 0.004) in the IG. The mean number of accurate lifestyle factors (that could affect fertility) mentioned increased from 3.6 to 4.4 (P < 0.001) in the IG. There were no improvements in the control group. Among the men in the IG, 76% had a positive experience of the counselling, and 77% had received new information. CONCLUSION The intervention managed to increase different aspects of men's fertility awareness. In the future, the format for preconception care for men needs further development. Including men in preconception health policy guidelines and identifying suitable actors for care provision would be important first steps.

Effects of Diet-Induced Obesity and Deficient in Vitamin D on Spermatozoa Function and DNA Integrity in Sprague-Dawley Rats. BIOMED RESEARCH INTERNATIONAL 2018; 2018:5479057.

Abstract
Obesity has adverse effects on male fertility and usually is diagnosed with a prevalence of vitamin D deficiency (VD−). Discussion on the impact of obesity/VD− on sperm function has been limited. This study analyzed the effects of diet-induced obesity/VD− on viability and plasma membrane integrity (PMI), superoxide anion (O2−) level, and DNA fragmentation (DNAfrag) in sperm Sprague-Dawley rats. The males were randomized into four groups and fed for a period of 12 weeks: G1: control diet with vitamin D (C/VD+), G2: control diet without vitamin D (C/VD−), G3: high-fat diet with vitamin D (HF/VD+), and G4: high-fat diet without vitamin D (HF/VD−). Sperm function parameters were analyzed by flow cytometry. PMI percentages and O2− levels were not affected by any of the diets. DNA fragmentation was increasing significantly (p<0.05) in the spermatozoa of animals with diets vitamin D deficient (G2) and diet-induced obesity (G4). Our results allow us to point out that diet-induced obesity and VD− produce greater damage in DNA sperm of rats. The use of nutraceuticals containing vitamin D could be reducing the risk of fragmentation of DNA in spermatozoa.

Abstract
Permanent childlessness is increasingly acknowledged as an outcome of a dynamic, context-dependent process, but few studies have integrated a life course framework to investigate the complex pathways leading to childlessness. This study focuses on an understudied yet revealing dimension of why individuals remain childless: stated fertility expectations over the life course. Using data from the National Longitudinal Survey of Youth 1979 cohort, I use a combination of sequence analysis, data-driven clustering techniques, and multivariable regression models to identify and describe groups of permanently childless women who follow similar trajectories of stated fertility expectations. Results indicate that a little more than one-half (56 %) of eventually childless women fall into a cluster where childlessness is expected before age 30. Women in the remaining clusters (44 %) transition to expecting childlessness later in the life course but are differentiated by the types of trajectories that precede the emergence of a childless expectation. Results from multivariable regression show that several respondent characteristics, including race/ethnicity, education, and marital history, predict cluster membership. Taken together, these findings add to a growing body of literature that provides a more nuanced description of permanently childless women and motivates further research that integrates interdependencies between life course domains and fertility expectations and decision-making of those who remain childless.

Abstract
Background It has been known that acupuncture treatment relieves gynecological disorders such as menopause, ovarian dysfunction, and dysmenorrhea. Sex hormones, including estrogen, progesterone, and gonadotropins, are related to the women disease. However, regulative effect of acupuncture on sex hormones has not been fully identified. Methods Acupuncture articles including analysis of sex hormones were searched in electronic databases from inception to June 2018. The methodological quality was assessed using modified CAMRADES tool. A total of 23 articles were selected and analyzed. Results In the results, overall studies showed that acupuncture increases estrogen, especially estradiol, progesterone, prolactin, and other hormones. Estradiol level was increased in most of studies except 3 studies which resulted in decreased level or not meaningful change. Two studies showed increase of FSH and LH whereas it was decreased in other studies. Other hormones were mostly increased by acupuncture. Conclusion This study possibly indicates that acupuncture changes sex hormone in various gynecological conditions in women.

Abstract
OBJECTIVE This study aimed to investigate the interaction between obesity, low-calorie sweeteners, and prebiotic oligofructose on reproductive parameters in rats. METHODS Data were derived from two separate studies of female Sprague-Dawley rats with (1) Lean (n = 24), (2) Obese (n = 27), (3) Obese+Aspartame (n = 14), (4) Obese+Stevia (n = 15), and (5) Obese+Prebiotic (n = 15) groups. Obesity was induced with a high-fat/high-sucrose diet prior to pregnancy. In one study, human-approved doses of aspartame (5-7 mg/kg/d) and stevia (2-3 mg/kg/d) in drinking water were examined, and in the second, 10% prebiotics (oligofructose) in the diet was examined. Reproductive parameters, including fertility, pregnancy, and delivery indexes, were analyzed. RESULTS Obesity significantly reduced pregnancy index in Obese dams (60.7% successful pregnancies) compared with lean (100%). Obesity also reduced the number of pups born alive and pup survival percentage compared with those of Lean dams (P < 0.001). Only 53.3% of rats were able to conceive in the Obese+Stevia group, but if rats did become pregnant, they had 100% pregnancy and delivery index. While prebiotic administration rescued the pregnancy index, it could not remediate pup survival percentage (P = 0.025) in Obese dams. CONCLUSIONS Both obesity status and dietary ingredients affect the ability to conceive. Future rigorously controlled studies designed to examine reproductive outcomes in depth are needed to confirm these findings.

Abstract
Objective To evaluate the behavior of seminal parameters over the years - 2010 to May
2017. Methods A retrospective study, carried out from January 2010 to May 2017, covering
men who underwent sperm examination. Seminal parameters (volume, sperm
concentration, motility, morphology, age and duration of infertility in
years) of 23,504 men were evaluated. The groups were compared to each other
to check whether there were changes to the seminal parameters in that
period. Results There was no change over the years considering the time of infertility, in an
average of 3.78 years. The mean age of the patients was 36.53 years, with a
trend of increase in 0.2 years. In relation to the volume of semen samples,
the mean value was 3.29mL, with a decrease trend in 0.05mL. As for sperm
concentration, the average was 34.37 million/mL, with a decrease trend of
1.0 million/mL. Progressive sperm motility showed an average of 47.27% and
there was a decrease trend of 0.67%. Finally, sperm morphology presented an
average of 2.79% of normal spermatozoa, with a decrease trend of 0.33%. Conclusion It can be noted that over the years, the sperm quality of men looking for
assisted reproduction clinics has tended to decrease in macroscopic and
microscopic parameters (volume, sperm concentration, motility and
morphology).

Abstract
Objective The current study focused on the pro-fertility potential of Senecio
biafrae (Sb) extract and vitamin C in Male Sprague Dawley (SD)
rats with tetracycline-induced infertility. Methods A total of 36 male and 36 female adult SD rats were used for this
investigation. The male rats randomly assigned to Group A (controls) were
given normal saline 2ml/kg. Rats in Groups B, C, D, E, and F were
respectively administered [30 mg/kg of body weight (bwt) of
tetracycline], [30 mg/kg bwt of tetracycline + 50 mg/kg of
vitamin C], [30 mg/kg bwt of tetracycline + 500 mg/kg bwt of
Sb], [30 mg/kg bwt of tetracycline + 50
mg/kg of vitamin C + 500 mg/kg bwt of Sb], and
[30 mg/kg bwt of tetracycline reversal] daily for 28 days via
gastric gavage. Tested parameters included sperm parameters, hormonal
profile, histology, and fertility test. Results Significant (p<0.05) increases were seen in sperm
quality, hormone profile, organ and body weights of the groups treated with
vitamin C, Sb, and tetracycline. There was derangement in
sperm quality, hormone profile, and organ and body weight of the animals in
group B. Histoarchtecture of the testes showed normal cellular composition
in the germinal epithelium with sperm cells in the lumen and normal
interstitium in groups A, C, D, and E. Group F showed abnormal
spermatogenesis and poor association of spermatogenic cells, however there
was depletion in the seminiferous epithelium in the group treated with
tetracycline. Conclusion Senecio biafrae defeated the deleterious effects of
tetracycline on the male reproductive system of rats treated with the
drug.

Abstract
RESEARCH QUESTION Does delaying IVF for 6 months in couples with unexplained infertility, compared with immediate IVF treatment, decrease the cost of IVF without compromising success rates? DESIGN Decision modelling was used to evaluate the cost and outcomes of immediate IVF versus delayed IVF for a cohort of women aged <40 years suffering unexplained infertility. Australian data and costs were used in the analysis. For different age groups, three scenarios were tested where 10%, 50% and 90% of couples with unexplained infertility delayed IVF for 6 months if they had a good prognosis for natural conception. The study included a total of 8781 couples aged <40 years, diagnosed with unexplained infertility and who had IVF in 2013. RESULTS The studied couples underwent 27,648 fresh and frozen embryo transfers, for an estimated total cost of $141 million. Potential out-of-pocket cost savings if 90% of couples delayed IVF ranged from $4.7 to $12.2 million, with Medicare cost savings of up to $15.1 million. The impact on the total pregnancy and live birth rates after 18 months was minimal. CONCLUSIONS In couples with unexplained infertility and a good prognosis for natural conception, delaying IVF for 6 months could substantially decrease out-of-pocket costs without compromising pregnancy and live birth rates over an 18-month period.

Abstract
The main risk factors for important reproductive health issues such as subfertility and perinatal mortality largely originate in the periconception period. To evaluate associations between modifiable maternal lifestyle factors and periconception outcomes, a systematic search was conducted for relevant studies published from 1990 to February 2017 on Embase, Medline, Web of Science, Cochrane database, PubMed and Google Scholar. The initial search identified 6166 articles, of which 49 studies were eligible for inclusion. Fecundity (the capacity to have a live birth) showed significant inverse associations with smoking, alcohol use and poor diet. Studies regarding time to pregnancy showed a decline in fecundity ratios (the monthly conception rate among exposed relative to unexposed couples) with increasing body mass index (BMI). Furthermore, risk of first-trimester miscarriage was found to be increased in smokers, alcohol and caffeine consumers, and with increasing BMI. Vitamin supplement use showed a decrease in this risk. This review demonstrates that maternal modifiable lifestyle factors affect periconception outcomes. If couples planning a pregnancy are more aware and supported to adopt healthy lifestyles during the periconceptional 'window of opportunity', short-term reproductive health as well as health in later life and even of future generations can be further improved.

Abstract
STUDY QUESTION Are specific gravity (SG)-adjusted urinary concentrations of 3-(diethylcarbamoyl)benzoic acid (DCBA) associated with semen parameters among men attending an academic fertility center? SUMMARY ANSWER Our study did not demonstrate any association between SG-adjusted urinary DCBA concentrations and semen parameters among men attending an academic fertility center. WHAT IS KNOWN ALREADY N,N-Diethyl-m-toluamide (DEET) is the most common active ingredient in consumer insect repellents. The recent rise in public health concerns regarding mosquito-borne diseases such as Zika, have led to an increased use of DEET insect repellents, especially among couples planning pregnancy. Animal studies have observed reproductive toxicity from DEET exposure. However, the reproductive health effects of DEET and its metabolites on human reproduction are unknown. STUDY DESIGN, SIZE, DURATION Between 2007 and 2015, 90 men participating in a prospective cohort study at the Massachusetts General Hospital Fertility Center provided 171 urine samples and 250 semen samples for analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS The urinary concentrations of DEET, N,N-diethyl-3-hydroxymethylbenzamide (DHMB) and DCBA were quantified by isotope-dilution tandem mass spectrometry and adjusted by SG. We used linear mixed models to evaluate the association between tertiles of SG-adjusted urinary DCBA concentrations and semen parameters (semen volume, sperm concentration, total sperm count, progressive motility, total progressive motility count, normal morphology and total normal morphology count), adjusting for covariates. DEET and DHMB were not considered for analysis because of the low percentage of detectable concentrations (<7%). Effect modification by BMI and smoking status was explored. MAIN RESULTS AND THE ROLE OF CHANCE Participants had a median age of 36 years and BMI of 27 kg/m2, and 68% had never smoked. The SG-adjusted geometric mean DCBA urinary concentration was 2.20 μg/l, with 85% detection frequency. The majority of semen parameters fell within the normal range with the exception of progressive motility, where 64% of the men had values below the WHO 2010 lower reference limits. SG-adjusted urinary DCBA concentrations were not associated with semen parameters in unadjusted or adjusted models. Men in the highest tertile of SG-adjusted urinary DCBA concentrations had comparable semen parameters to men in the lowest tertile (2.59 vs. 2.88 ml for semen volume, 47.9 vs. 45.8 million/ml for sperm concentration, 116 vs. 118 million for total sperm count, 25 vs. 24% for progressive sperm motility, and 6.1 vs. 5.8% for morphologically normal sperm). In addition, BMI and smoking status did not modify the associations. LIMITATIONS REASONS FOR CAUTION We had a relatively small sample size with similar socioeconomic backgrounds and with overall relatively low urinary concentrations of DEET biomarkers. However, our sample size was enough to detect moderate differences with at least 80% statistical power, between the first and third tertiles of urinary DCBA concentrations. Limitations also include possible misclassification of DCBA exposure and difficulties in extrapolating the findings to the general population. WIDER IMPLICATIONS OF THE FINDINGS Our study found no associations between urinary concentrations of DCBA, a major metabolite of the insect repellent DEET, and semen parameters in men presenting for infertility treatment. While these results are reassuring, further studies including larger sample sizes and higher exposures are warranted. STUDY FUNDING/COMPETING INTEREST(S) The project was financed by the National Institute of Health grants R01ES022955 and R01ES009718 and by grant P30ES000002 from the National Institute of Environmental Health Sciences (NIEHS).

Genetic evaluation of patients with non-syndromic male infertility. J Assist Reprod Genet 2018; 35:1939-1951. [PMID: 30259277 DOI: 10.1007/s10815-018-1301-7] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Accepted: 08/28/2018] [Indexed: 02/06/2023] Open
Abstract
PURPOSE This review provides an update on the genetics of male infertility with emphasis on the current state of research, the genetic disorders that can lead to non-syndromic male infertility, and the genetic tests available for patients. METHODS A comprehensive review of the scientific literature referenced in PubMed was conducted using keywords related to male infertility and genetics. The search included articles with English abstracts appearing online after 2000. RESULTS Mutations in 31 distinct genes have been identified as a cause of non-syndromic human male infertility, and the number is increasing constantly. Screening gene panels by high-throughput sequencing can be offered to patients in order to identify genes involved in various forms of human non-syndromic infertility. We propose a workflow for genetic tests which takes into account semen alterations. CONCLUSIONS The identification and characterization of the genetic basis of male infertility have broad implications not only for understanding the cause of infertility but also in determining the prognosis, selection of treatment options, and management of couples. Genetic diagnosis is essential for the success of ART techniques and for preserving future fertility as well as the prognosis for testicular sperm extraction (TESE) and adopted therapeutics.

Henkel R, Sandhu IS, Agarwal A. The excessive use of antioxidant therapy: A possible cause of male infertility? Andrologia 2018; 51:e13162. [PMID: 30259539 DOI: 10.1111/and.13162] [Citation(s) in RCA: 90] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2018] [Revised: 08/22/2018] [Accepted: 09/04/2018] [Indexed: 12/18/2022] Open
Abstract
Reactive oxygen species and oxidative stress are closely associated with various pathologies such as neurodegenerative diseases, ageing and male infertility. Hence, antioxidants such as vitamin C, vitamin E, N-acetyl cysteine, L-carnitine and folic acid are regularly used in various treatment regimens to protect cells from the damage induced by free radicals. However, given their over-the-counter availability at unnaturally high concentrations and also the fact that they are commonly added to various food products, patients may run a risk of consuming excessive dosages of these compounds, which may then be toxic. The few studies that have assessed antioxidant overuse and the associated adverse effects found that large doses of dietary antioxidant supplements have varying-if any-therapeutic effects even though free radicals clearly damage cells-a phenomenon that has been termed the "antioxidant paradox." Furthermore, overuse of antioxidants such as vitamin C, vitamin E, N-acetyl cysteine may lead to reductive stress, which is reported to be as dangerous to cells as oxidative stress and can be the cause of diseases such as cancer or cardiomyopathy. Therefore, we feel that there is a need for more elaborate research to establish the clear benefits and risks involved in antioxidant therapy for male infertility.
