Abstract
STUDY QUESTION Do children born to mothers with polycystic ovary syndrome (PCOS) have an adverse cardiometabolic profile including arterial stiffness at 9 years of age compared to other children? SUMMARY ANSWER Children of mothers with PCOS did not have differing cardiometabolic outcomes than children without exposure. WHAT IS KNOWN ALREADY While women with PCOS themselves have higher risk of cardiometabolic conditions such as obesity and diabetes, the evidence on intergenerational impact is unclear. Given in utero sequalae of PCOS (e.g. hyperandrogenism, insulin resistance), the increased risk could be to both boys and girls. STUDY DESIGN, SIZE, DURATION The Upstate KIDS cohort is a population-based birth cohort established in 2008-2010 to prospectively study the impact of infertility treatment on children's health. After ∼10 years of follow-up, 446 mothers and their 556 children attended clinical visits to measure blood pressure (BP), heart rate, arterial stiffness by pulse wave velocity (PWV), mean arterial pressure, lipids, high-sensitivity C-reactive protein (hsCRP), hemoglobin A1c (HbA1c), and anthropometrics. PARTICIPANTS/MATERIALS, SETTING, METHODS Women self-reported ever diagnoses of PCOS ∼4 months after delivery of their children in 2008-2010. Linear regression models applying generalized estimating equations to account for correlation within twins were used to examine associations with each childhood cardiometabolic outcome. MAIN RESULTS AND THE ROLE OF CHANCE In this cohort with women oversampled on infertility treatment, ∼14% of women reported a PCOS diagnosis (n = 61). We observed similarities in BP, heart rate, PWV, lipids, hsCRP, HbA1c, and anthropometry (P-values >0.05) among children born to mothers with and without PCOS. Associations did not differ by child sex. LIMITATIONS, REASONS FOR CAUTION The sample size of women with PCOS precluded further separation of subgroups (e.g. by hirsutism). The population-based approach relied on self-reported diagnosis of maternal PCOS even though self-report has been found to be valid. Participants were predominantly non-Hispanic White and a high proportion were using fertility treatment due to the original design. Differences in cardiometabolic health may be apparent later in age, such as after puberty. WIDER IMPLICATIONS OF THE FINDINGS Our results provide some reassurance that cardiometabolic factors do not differ in children of women with and without self-reported PCOS during pregnancy.

Female reproductive function after treatment of childhood acute lymphoblastic leukemia. Pediatr Blood Cancer 2021; 68:e28894. [PMID: 33459500 DOI: 10.1002/pbc.28894] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Revised: 12/04/2020] [Accepted: 12/24/2020] [Indexed: 11/06/2022]
Abstract
BACKGROUND The aim was to evaluate self-reported reproductive characteristics and markers of ovarian function in a nationwide cohort of female survivors of childhood acute lymphoblastic leukemia (ALL), because prior investigations have produced conflicting data. PROCEDURE Self-reported reproductive characteristics were assessed by questionnaire among 357 adult 5-year survivors, treated between 1964 and 2002, and 836 controls. Ovarian function was assessed by serum levels of anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), and inhibin B and by antral follicle count (AFC). Differences between controls and (subgroups of) survivors (total group, chemotherapy [CT]-only group, CT and radiotherapy [RT] group) were analyzed. RESULTS Survivors treated with CT only do not differ from controls regarding timing of menarche, virginity status, desire for children, or pregnancy rates. Compared to controls, the CT+RT group was at significantly increased risk of a younger age at menarche (P < .01), virginity, an absent desire for children, and lower pregnancy rates (odds ratio [OR] [95% CI]: 0.3 [CI 0.1-0.6], 0.5 [0.3-0.9], and 0.4 [0.2-0.9], respectively). Survivors in the CT-only group were significantly younger at the birth of their first child. Pregnancy outcomes were not significantly different between any (sub)groups. Survivors treated with total body irradiation (TBI) or hematopoietic stem cell transplantation (HSCT) are at increased risk of abnormal markers of ovarian function. CONCLUSION Reproductive function of ALL survivors treated with CT only does not differ from controls. However, survivors additionally treated with RT seem to be at an increased risk of certain adverse reproductive outcomes. Providing personalized counseling about (future) reproductive health risks in this group is imperative.

Jung AM, Missmer SA, Cramer DW, Ginsburg ES, Terry KL, Vitonis AF, Farland LV. Self-reported infertility diagnoses and treatment history approximately 20 years after fertility treatment initiation. FERTILITY RESEARCH AND PRACTICE 2021; 7:7. [PMID: 33712085 PMCID: PMC7953690 DOI: 10.1186/s40738-021-00099-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Accepted: 03/01/2021] [Indexed: 11/17/2022]
Abstract
Background Infertility history may have important implications for clinical practice and scientific discovery. Previous research on the validity of self-reported infertility measurements has been limited in scope and duration (< 5 years). In this study, we validated self-reported infertility history measures 15–23 years after fertility treatment initiation among women who utilized assisted reproductive technology (ART). Methods Women who received ART treatments from three Boston infertility clinics and who enrolled in a prior study (1994–2003) were re-contacted in 2018 for the AfteR Treatment Follow-up Study (ART-FS). Infertility history was collected from clinical records and two self-report questionnaires (at ART initiation and at ART-FS enrollment). Treatment history included specific details (fresh or frozen embryo transfers, number of cycles) and treatment recall prior to ART initiation. Self-reported infertility diagnoses included polycystic ovary syndrome (PCOS), endometriosis, uterine factor infertility, tubal factor infertility, diminished ovarian reserve/advanced maternal age, male factor infertility, and other/unknown. We compared self-reported measures from 2018 to self-reported and clinical data from prior study initiation, using Cohen’s kappa, sensitivity, specificity, and 95% confidence intervals. Results Of 2644 women we attempted to recontact, 808 completed the ART-FS, with an average follow-up of 19.6 years (standard deviation: 2.7). Recall of fertility treatment usage had moderate sensitivity (IVF = 0.85, Clomiphene/Gonadotropin = 0.81) but low specificity across different infertility treatment modalities (IVF = 0.63, Clomiphene/Gonadotropin = 0.55). Specific IVF details had low to moderate validity and reliability with clinical records. Reliability of recalled infertility diagnosis was higher when compared to self-report at ART initiation (PCOS K = 0.66, Endometriosis K = 0.76, Tubal K = 0.73) than when compared to clinical records (PCOS K = 0.31, Endometriosis K = 0.48, Tubal K = 0.62) and varied by diagnosis. Conclusions The ability of women to recall specific IVF treatment details was moderately accurate and recall of self-reported infertility diagnosis varied by diagnosis and measurement method.

Anti-Müllerian Hormone Levels in Adolescence in Relation to Long-term Follow-up for Presence of Polycystic Ovary Syndrome. J Clin Endocrinol Metab 2021; 106:e1084-e1095.

Abstract
CONTEXT Anti-Müllerian hormone (AMH) measured in adolescence as biomarker for prediction of adult polycystic ovary syndrome (PCOS) is doubtful but not substantiated. OBJECTIVE To investigate whether serum AMH levels and other PCOS-associated features in adolescence can predict the presence of PCOS in adulthood. DESIGN AND SETTING A long-term follow-up study based on a unique adolescent study on menstrual irregularities performed between 1990 and 1997. PARTICIPANTS AND INTERVENTIONS AMH was assayed in 271 adolescent girls. Data on PCOS features were combined with AMH levels. In 160 of the 271 (59%) participants, we collected information in adulthood about their menstrual cycle pattern and presence of PCOS (features) by questionnaire 2 decades after the initial study. RESULTS AMH was higher in adolescent girls with oligomenorrhea compared with girls with regular cycles, median (interquartile range): 4.6 (3.1-7.5) versus 2.6 (1.7-3.8) μg/L (P < 0.001). Women with PCOS in adulthood had a higher median adolescent AMH of 6.0 compared with 2.5 μg/L in the non-PCOS group (P < 0.001). AMH at adolescence showed an area under the receiver operating characteristic curve for PCOS in adulthood of 0.78. In adolescent girls with oligomenorrhea the proportion developing PCOS in adulthood was 22.5% (95% CI, 12.4-37.4) against 5.1% (95% CI, 2.1-12.0) in girls with a regular cycle (P = 0.005). Given adolescent oligomenorrhea, adding high AMH as factor to predict adult PCOS or adult oligomenorrhea was of no value. CONCLUSIONS Adolescent AMH either alone or adjuvant to adolescent oligomenorrhea does not contribute as prognostic marker for PCOS in adulthood. Therefore, we do not recommend routine its use in clinical practice.

The associations of maternal polycystic ovary syndrome and hirsutism with behavioral problems in offspring. Fertil Steril 2020; 113:435-443. [PMID: 32106995 DOI: 10.1016/j.fertnstert.2019.09.034] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2019] [Revised: 09/10/2019] [Accepted: 09/20/2019] [Indexed: 12/13/2022]
Abstract
OBJECTIVE To study the associations between maternal polycystic ovary syndrome (PCOS) and hirsutism with offspring attention-deficit/hyperactivity disorder (ADHD), anxiety, conduct disorder, and behavioral problems. DESIGN Prospective birth cohort study. SETTING Not applicable. PATIENT(S) A total of 1,915 mother-child dyads. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Maternal report of offspring ADHD, anxiety, or conduct disorder diagnosis at 7 to 8 years; emotional symptoms, behavioral problems (including peer relationship, conduct, hyperactivity/inattention), and prosocial problems measured with the Strengths and Difficulties Questionnaire (SDQ) at 7 years. RESULT(S) Prevalence of PCOS and hirsutism were 12.0% and 3.9%; 84% of women with hirsutism had PCOS. After adjustment for sociodemographic covariates, prepregnancy body mass index, and parental history of affective disorders, children born to mothers with PCOS had higher risk of anxiety (adjusted risk ratio [aRR] 1.62; 95% confidence interval [CI], 1.02-2.57) and borderline emotional symptoms (aRR 1.66; 95% CI, 1.18-2.33) compared with children born to mothers without PCOS. The associations between maternal PCOS and offspring ADHD were positive but imprecise. Maternal hirsutism was related to a higher risk of children's ADHD (aRR 2.33; 95% CI, 1.28-4.24), conduct disorder (aRR 2.54; 95% CI 1.18-5.47), borderline emotional symptoms, peer relationship problems, and conduct problems (aRRs 2.61; 95% CI, 1.69-4.05; 1.92; 95% CI, 1.16-3.17; and 2.22; 95% CI, 1.30-3.79, respectively). CONCLUSION(S) Maternal PCOS was associated with offspring anxiety, and hirsutism was related to other offspring behavioral problems. These findings should be interpreted with caution as replication is needed in prospective cohort studies that assess PCOS and hirsutism diagnoses using medical records.

Abstract
Purpose To evaluate pregnancy rates, time to pregnancy (TTP) and obstetric outcomes in female childhood cancer survivors (CCSs) and to identify specific diagnosis- and treatment-related factors associated with these outcomes. Methods The study is part of the DCOG LATER-VEVO study, a nationwide multicenter cohort study evaluating fertility among long-term Dutch female CCSs. Data were collected by questionnaire. The current study included 1095 CCSs and 812 controls, consisting of sisters of CCSs and a random sample of women from the general population. Results Among the subgroup of women who ever had the desire to become pregnant, the chance of becoming pregnant was significantly lower for CCSs than controls (OR 0.5, 95%CI 0.4–0.8). Moreover, TTP was 1.1 times longer for CCSs compared to controls (p = 0.09) and was significantly longer in survivors of CNS and renal tumours. Overall, no differences were found between CCSs and controls regarding the probability of ever having had a miscarriage, still birth, or induced abortion. However, CCSs had a significantly increased risk of delivering preterm (OR 2.2, 95%CI 1.3–3.7) and delivering via caesarean section (OR 1.8, 95%CI 1.2–2.6). Treatment with lower abdominal/pelvic radiotherapy was strongly associated with several adverse obstetric outcomes. Conclusion CCSs are less likely to have ever been pregnant. Among those who do become pregnant, certain subgroups of CCSs are at increased risk of longer TTP. Moreover, as pregnant CCSs, especially those treated with lower abdominal/pelvic radiotherapy, are more likely to develop various adverse obstetric outcomes, appropriate obstetric care is highly advocated.

Abstract
STUDY QUESTION Do female childhood cancer survivors (CCSs) express a decreased desire to have children and do they use reproductive health care more often compared to women without a history of cancer? SUMMARY ANSWER Overall, no difference was found in the desire to have children between CCSs and controls, whereas CCSs consult a fertility specialist more often, at a younger age, and sooner after their first attempt at conceiving. WHAT IS KNOWN ALREADY Female CCSs may face a shorter than anticipated reproductive window as a result of their cancer treatment. Little is known about their desire to have children and use of reproductive health care, especially in relation to their former cancer treatment. STUDY DESIGN, SIZE, DURATION This study is part of the DCOG LATER-VEVO study, a nationwide retrospective cohort study on female fertility in Dutch CCSs. In total, 1749 CCSs and 1673 controls were invited for the study. Data collection took place between January 2008 and May 2014. PARTICIPANTS/MATERIALS, SETTING, METHODS Data on the desire to have children and use of reproductive health care were collected by questionnaire. The control group consisted of sisters from CCSs and females from the general population. In total, 1106 (63%) CCSs and 818 (49%) controls completed the questionnaire. MAIN RESULTS AND THE ROLE OF CHANCE Overall, no difference was found in the desire to have children between CCSs and controls (86% and 89%, respectively). However, survivors of a CNS tumour were less likely to desire children and CCSs without biological children at time of study were more likely to report that their desire to have children was unfulfilled because of medical reasons (9%), compared to controls (1%). In total, 12% of CCSs ever consulted a fertility specialist compared to 10% of controls (OR = 1.7, 95% CI: 1.3-2.4). Mean (SD) age at time of their first visit was 27.7 (4.4) years for CCSs and 29.9 (3.9) years for controls (P < 0.01). In total, 43% of CCSs consulted a fertility specialist within 12 months after they had started trying to achieve a pregnancy, compared to 27% of controls. Risk factors for consulting a fertility specialist included a previous diagnosis of renal tumour, leukaemia, lymphoma or a CNS tumour, and treatment with alkylating chemotherapy, gonadotoxic radiotherapy or both. In total, 70% of CCSs reported a female factor as cause of subfertility compared to 34% of controls (OR = 4.5, 95% CI: 2.3-8.7) and in this specific group, CCSs seemed more likely to use fertility treatment (OR = 2.9, 95% CI: 1.0-8.2). LIMITATIONS, REASONS FOR CAUTION Because of the low number of CCSs who used fertility treatment, we were not able to look at specific diagnoses and treatment types associated with using fertility treatment. Nevertheless, we were able to identify diagnostic- and treatment-related risk factors for consulting a fertility specialist. Details regarding consultations with a fertility specialist and fertility treatment were based on self-report and may therefore be subject to recall bias. WIDER IMPLICATIONS OF THE FINDINGS Decisions about parenthood affect all CCSs. It's important to evaluate reproductive intentions and function timely after cancer treatment, so CCSs can be adequately counselled regarding family planning and fertility treatment.

Sex Transm Infect 2019; 95:300-306. [PMID: 30606817 PMCID: PMC6585279 DOI: 10.1136/sextrans-2018-053778] [Citation(s) in RCA: 42] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Revised: 10/30/2018] [Accepted: 11/15/2018] [Indexed: 11/04/2022] Open
Abstract
OBJECTIVES A better understanding of Chlamydia trachomatis infection (chlamydia)-related sequelae can provide a framework for effective chlamydia control strategies. The objective of this study was to estimate risks and risk factors of pelvic inflammatory disease (PID), ectopic pregnancy and tubal factor infertility (TFI) with a follow-up time of up until 8 years in women previously tested for chlamydia in the Chlamydia Screening Implementation study (CSI) and participating in the Netherlands Chlamydia Cohort Study (NECCST). METHODS Women who participated in the CSI 2008-2011 (n=13 498) were invited in 2015-2016 for NECCST. Chlamydia positive was defined as a positive CSI-PCR test, positive chlamydia serology and/or self-reported infection (time dependent). Data on PID, ectopic pregnancy and TFI were collected by self-completed questionnaires. Incidence rates and HRs were compared between chlamydia-positive and chlamydia-negative women corrected for confounders. RESULTS Of 5704 women included, 29.5% (95% CI 28.3 to 30.7) were chlamydia positive. The incidence rate of PID was 1.8 per 1000 person-years (py) (1.6 to 2.2) overall, 4.4 per 1000 py (3.3 to 5.7) among chlamydia positives compared with 1.4 per 1000 py (1.1 to 1.7) for chlamydia negatives. For TFI, this was 0.4 per 1000 py (0.3 to 0.5) overall, 1.3 per 1000 py (0.8 to 2.1) and 0.2 per 1000 py (0.1 to 0.4) among chlamydia positives and negatives, respectively. And for ectopic pregnancy, this was 0.6 per 1000 py (0.5 to 0.8) overall, 0.8 per 1000 py (0.4 to 1.5) and 0.6 per 1000 py (0.4 to 0.8) for chlamydia negatives. Among chlamydia-positive women, the strongest risk factor for PID was symptomatic versus asymptomatic infection (adjusted HR 2.88, 1.4 to 4.5) and for TFI age <20 versus >24 years at first infection (HR 4.35, 1.1 to 16.8). CONCLUSION We found a considerably higher risk for PID and TFI in chlamydia-positive women, but the incidence for ectopic pregnancy was comparable between chlamydia-positive and chlamydia-negative women. Overall, the incidence rates of sequelae remained low. TRIAL REGISTRATION NTR-5597.

Abstract
Previous studies of associations between ASD and conception using assisted reproductive technology (ART) are inconsistent and few studies have examined associations with other infertility treatments or infertility disorders. We examined associations between ASD and maternal/paternal infertility disorders and numerous maternal treatments among 1538 mother-child pairs in the Study to Explore Early Development, a population-based case-control study. ASD was associated with any female infertility diagnosis and several specific diagnoses: blocked tubes, endometriosis, uterine-factor infertility, and polycystic ovarian syndrome. Stratified analyses suggested associations were limited to/much stronger among second or later births. The findings were not explained by sociodemographic factors such as maternal age or education or multiple or preterm birth. ASD was not associated with ART or non-ART infertility treatments.

Abstract
PURPOSE Endometriosis is associated with ovarian cancer, but the relation with endometrial cancer is unclear. Prior studies generally were retrospective and had potential limitations, including use of self-reported endometriosis, failure to account for delays between symptom onset and endometriosis diagnosis, and changes in risk factors post-endometriosis diagnosis. We evaluated whether these limitations obscured a weak association with endometrial cancer and the extent to which these limitations impacted associations with ovarian cancer. METHODS Cox proportional hazards regression models were used to assess associations between endometriosis and cancer risk, evaluating the impacts of self-reported vs. laparoscopically confirmed endometriosis, delayed diagnosis, and post-endometriosis diagnosis changes in risk factor exposures on relative risk estimates. RESULTS Over 18 years of follow-up, we identified 228 ovarian and 166 endometrial cancers among 102,025 and 97,109 eligible women, respectively. Self-reported endometriosis was associated with ovarian cancer [relative risk (RR): 1.81; 95% confidence interval (CI): 1.26-2.58]; this association was stronger for laparoscopically confirmed endometriosis (HR: 2.14; 95% CI 1.45-3.15). No association was observed with endometrial cancer (self-report RR: 0.78; 95% CI 0.42-1.44; laparoscopic-confirmation RR: 0.76; 95% CI 0.35-1.64). Accounting for diagnosis delays or post-endometriosis diagnosis changes in risk factors had a little impact. CONCLUSIONS This study adds to the evidence that endometriosis is not strongly linked to endometrial cancer risk and that the association with ovarian cancer is robust to misclassification, diagnostic delay, and changes in exposures post-endometriosis diagnosis. Our analysis suggests that confounding and misclassification do not obscure a weak association for endometrial cancer risk, although our results should be replicated.

Abstract
It is predicted that Japan and European Union will soon experience appreciable decreases in their populations due to persistently low total fertility rates (TFR) below replacement level (2.1 child per woman). In the United States, where TFR has also declined, there are ethnic differences. Caucasians have rates below replacement, while TFRs among African-Americans and Hispanics are higher. We review possible links between TFR and trends in a range of male reproductive problems, including testicular cancer, disorders of sex development, cryptorchidism, hypospadias, low testosterone levels, poor semen quality, childlessness, changed sex ratio, and increasing demand for assisted reproductive techniques. We present evidence that several adult male reproductive problems arise in utero and are signs of testicular dysgenesis syndrome (TDS). Although TDS might result from genetic mutations, recent evidence suggests that it most often is related to environmental exposures of the fetal testis. However, environmental factors can also affect the adult endocrine system. Based on our review of genetic and environmental factors, we conclude that environmental exposures arising from modern lifestyle, rather than genetics, are the most important factors in the observed trends. These environmental factors might act either directly or via epigenetic mechanisms. In the latter case, the effects of exposures might have an impact for several generations post-exposure. In conclusion, there is an urgent need to prioritize research in reproductive physiology and pathophysiology, particularly in highly industrialized countries facing decreasing populations. We highlight a number of topics that need attention by researchers in human physiology, pathophysiology, environmental health sciences, and demography.

Abstract
STUDY QUESTION Is ovarian or extra-ovarian endometriosis associated with an increased risk of ovarian cancer and borderline ovarian tumours (BOT)? SUMMARY ANSWER We found a 3- to 8-fold increased risk of ovarian tumours associated with endometriosis: the magnitude of the risk increase depended on the definition of endometriosis. WHAT IS KNOWN ALREADY There is increasing evidence of an association between endometriosis and increased risk of ovarian cancer. However, most reports were based on self-reported diagnosis of endometriosis. STUDY DESIGN, SIZE, DURATION We conducted a nationwide historic cohort study among women with subfertility problems between 1980 and 1995. For this analysis we selected all cohort members with endometriosis, and a comparison group of subfertile women (male factor or idiopathic) without endometriosis (total cohort of 8904 women). Median follow-up time was 15.2 for the entire study population. PARTICIPANTS/MATERIALS, SETTING, METHODS For this analysis we selected all cohort members with (n = 3657) and without (n = 5247) evidence of endometriosis. Seventy-eight per cent of diagnoses of endometriosis were confirmed by pathology report, and 22% was self-reported endometriosis (positive predictive value of 73%). We linked the cohort with the Dutch Pathology Database and the Netherlands Cancer Registry to assess the occurrence of ovarian cancer and BOT between January 1989 and June 2007. MAIN RESULTS AND THE ROLE OF CHANCE We observed a substantially increased risk of all ovarian malignancies combined in women with endometriosis when we based the definition of endometriosis on self-report, medical records information at subfertility treatment and/or the nationwide pathology database (hazard ratio (HR) 8.2; 95% confidence interval (CI) 3.1-21.6). The HR associated with endometriosis was 12.4 (95% CI 2.8-54.2) for ovarian cancer and 5.5 (95% CI 1.5-20.2) for BOT. When we excluded information from the pathology database, HRs were 3.0 (95% CI 1.5-6.1) for all ovarian tumours, 4.3 (95% CI 1.6-11.2) for ovarian cancer and 1.9 (95% CI 0.6-5.8) for BOT. Both ovarian and extra-ovarian endometriosis carried a significantly increased risk for ovarian cancer and BOT. LIMITATIONS, REASONS FOR CAUTION We did not have information on oral contraceptive use and parity for 23.4 and 3.4%, of women in the analytic cohort, respectively. Furthermore, a limitation of our study, and also of other studies, is that the date of diagnosis of endometriosis is usually made long after the onset of the disease. Also, the number of cases in the cohort is small (n = 34), resulting in wide CIs. WIDER IMPLICATIONS OF THE FINDINGS The fact that endometriosis was assessed before diagnosis of ovarian malignancy and the high degree of medical confirmation in our study likely contribute to the validity of our estimate of a 3- to 8-fold increased risk of ovarian tumours associated with endometriosis. The risk of ovarian malignancies associated with endometriosis was much higher in analyses including information on endometriosis from the nationwide pathology database, implying that risk estimates from studies using self-reported information on endometriosis may be too low due to non-differential misclassification bias. STUDY FUNDING/COMPETING INTEREST(S) None. TRIAL REGISTRATION NUMBER None.

Abstract
BACKGROUND Advances in childhood cancer treatment over the past decades have significantly improved survival, resulting in a rapidly growing group of survivors. However, both chemo- and radiotherapy may adversely affect reproductive function. This paper describes the design and encountered methodological challenges of a nationwide study in the Netherlands investigating the effects of treatment on reproductive function, ovarian reserve, premature menopause and pregnancy outcomes in female childhood cancer survivors (CCS), the DCOG LATER-VEVO study. METHODS The study is a retrospective cohort study consisting of two parts: a questionnaire assessing medical, menstrual, and obstetric history, and a clinical assessment evaluating ovarian and uterine function by hormonal analyses and transvaginal ultrasound measurements. The eligible study population consists of adult female 5-year survivors of childhood cancer treated in the Netherlands, whereas the control group consists of age-matched sisters of the participating CCS. To date, study invitations have been sent to 1611 CCS and 429 sister controls, of which 1215 (75%) and 333 (78%) have responded so far. Of these responders, the majority consented to participate in both parts of the study (53% vs. 65% for CCS and sister controls respectively). Several challenges were encountered involving the study population: dealing with bias due to the differences in characteristics of several types of (non-) participants and finding an adequately sized and well-matched control group. Moreover, the challenges related to the data collection process included: differences in response rates between web-based and paper-based questionnaires, validity of self-reported outcomes, interpretation of clinical measurements of women using hormonal contraceptives, and inter- and intra-observer variation of the ultrasound measurements. DISCUSSION The DCOG LATER-VEVO study will provide valuable information about the reproductive potential of paediatric cancer patients as well as long-term survivors of childhood cancer. Other investigators planning to conduct large cohort studies on late effects may encounter similar challenges as those encountered during this study. The solutions to these challenges described in this paper may be useful to these investigators. TRIAL REGISTRATION NTR2922; http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=2922

Abstract
STUDY QUESTION What is the self-reported use of in vitro fertilization (IVF) and ovulation induction (OI) in comparison with insurance claims by Australian women aged 28-36 years? SUMMARY ANSWER The self-reported use of IVF is quite likely to be valid; however, the use of OI is less well reported. WHAT IS KNOWN AND WHAT THIS PAPER ADDS Population-based research often relies on the self-reported use of IVF and OI because access to medical records can be difficult and the data need to include sufficient personal identifying information for linkage to other data sources. There have been few attempts to explore the reliability of the self-reported use of IVF and OI using the linkage to medical insurance claims for either treatment. STUDY DESIGN This prospective, population-based, longitudinal study included the cohort of women born during 1973-1978 and participating in the Australian Longitudinal Study on Women's Health (ALSWH) (n = 14247). From 1996 to 2009, participants were surveyed up to five times. PARTICIPANTS AND SETTING Participants self-reported their use of IVF or OI in two mailed surveys when aged 28-33 and 31-36 years (n = 7280), respectively. This study links self-report survey responses and claims for treatment or medication from the universal national health insurance scheme (i.e. Medicare Australia). MAIN RESULTS AND THE ROLE OF CHANCE Comparisons between self-reports and claims data were undertaken for all women consenting to the linkage (n = 3375). The self-reported use of IVF was compared with claims for OI for IVF (Kappa, K = 0.83), oocyte collection (K = 0.82), sperm preparation (K = 0.83), intracytoplasmic sperm injection (K = 0.40), fresh embryo transfers (K = 0.82), frozen embryo transfers (K = 0.64) and OI for IVF medication (K = 0.17). The self-reported use of OI was compared with ovulation monitoring (K = 0.52) and OI medication (K = 0.71). BIAS, CONFOUNDING AND OTHER REASONS FOR CAUTION There is a possibility of selection bias due to the inclusion criteria for participants in this study: (1) completion of the last two surveys in a series of five and (2) consent to the linkage of their responses with Medicare data. GENERALIZABILITY TO OTHER POPULATIONS The results are relevant to questionnaire-based research studies with infertile women in developed countries.

Abstract
The evaluation of cancer risk among patients treated for infertility is complex, given the need to consider indications for use, treatment details, and the effects of other factors (including parity status) that independently affect cancer risk. Many studies have had methodologic limitations. Recent studies that have overcome some of these limitations have not confirmed a link between drug use and invasive ovarian cancers, although there is still a lingering question as to whether borderline tumors might be increased. It is unclear whether this merely reflects increased surveillance. Investigations regarding breast cancer risk have produced inconsistent results. In contrast, an increasing number of studies suggest that fertility drugs may have a special predisposition for the development of uterine cancers, of interest given that these tumors are recognized as particularly hormonally responsive. Additional studies are needed to clarify the effects on cancer risk of fertility drugs, especially those used in conjunction with in vitro fertilization. Because many women who have received such treatments are still relatively young, further monitoring should be pursued in large well-designed studies that enable assessment of effects within a variety of subgroups defined by both patient and disease characteristics.

Abstract
AIMS To compare prisoners' self-reported history of TBI associated with hospital attendance with details extracted from relevant hospital medical records and to identify factors associated with the level of agreement between the two sources. METHODS From a sample of prison entrants, this study obtained a history of TBIs for which medical attention was sought at a hospital. Audit tools were developed for data extraction relevant to any possible TBI from records at a total of 23 hospitals located within New South Wales, Australia. The level of agreement between self-report and hospital records was compared in relation to demographic, psychological and criminographic characteristics. RESULTS Of the 200 participants in the study, 164 (82%) reported having sustained a past TBI giving a total of 420 separate TBI incidents. Of these, 156 (37%) were alleged to have resulted in attendance at a hospital emergency department including 112 (72%) at a hospital accessible for the validation exercise. For 93/112 (83%) of reported TBIs, a corresponding hospital medical record was located of which 78/112 (70%) supported the occurrence of a TBI. Lower education and a lifetime history of more than seven TBIs were associated with less agreement between self-report and medical record data with regard to specific details of the TBI. CONCLUSIONS Overall, these findings suggest that prisoners' self-report of TBI is generally accurate when compared with the 'gold standard' of hospital medical record. This finding is contrary to the perception of this group as 'dishonest' and 'unreliable'.

Abstract
BACKGROUND An increasing number of children are born after assisted conception and in surveillance programmes information on mode of conception is often achieved via maternal self-report. We assessed the validity of self-reported assisted conception in The Danish National Birth Cohort (DNBC), a prospective pregnancy cohort. Here, the term assisted conception refers to IVF, ICSI, ovulation induction and insemination. METHODS We compared self-reported assisted conception in the DNBC to corresponding data from Danish national registers; the IVF Register and Danish Drug Prescription Register, providing method of conception in the entire population. In the DNBC, 101,042 women accepted the invitation in early pregnancy from 1996 to 2002. Our final study population comprised 88,151 DNBC women aged 20 years and older who participated in the first DNBC interview with a pregnancy resulting in a live born child. RESULTS In the DNBC, assisted conception was reported with a sensitivity of 83% and positive predictive value of 88%. Misclassification was largely explained by ambiguous phrasing of the DNBC interview question and interview skip patterns. Women with false negative reporting were more often multipara (P < 0.001) and older (P = 0.027 for IVF/ICSI and P = 0.002 for ovulation induction). The risk ratio (RR) for being born preterm in IVF/ICSI children was lower for children identified via the DNBC, RR 3.61 (95% confidence interval (CI) 3.31-3.94), than the IVF Register, RR 4.36 (95% CI 4.02-4.74). CONCLUSIONS There was a high positive predictive value of self-reported assisted conception in the DNBC, but the structure of the DNBC interview represented a problem and misclassification could introduce bias.

Abstract
Aims. This study assessed whether recent screening recommendations have led to increased diagnosis of type 2 diabetes mellitus (T2DM) through routine screening. Methods. Respondents to the 2006 US SHIELD survey reported whether a physician told them they had T2DM, age at diagnosis, specialty of the physician who made the diagnosis, and whether the diagnosis was made after having symptoms, during routine screening, or when being treated for another health problem. Results. Of 3 022 T2DM respondents, 36% of respondents reported that T2DM diagnosis was made during routine screening alone, 20% after having symptoms alone, and 6% when being treated for another health problem alone. The proportion of T2DM respondents reporting a diagnosis based only on screening increased approximately 42% over a 15+-year time span (absolute increase from 31% to 44%) (P < .001), whereas symptom-based diagnosis did not change significantly (P = .10). T2DM was diagnosed primarily by family physicians (88.3%). Conclusion. These findings highlight the importance of regular screening for diabetes and the vital role of primary care physicians in recognizing individuals with T2DM.

Abstract
Subfertility is a statistical concept. When a pregnancy has not been achieved within a year of unprotected intercourse, the odds are that an underlying pathological mechanism is at play. Advanced female age, longer duration and primary infertility, are important prognostic factors, suggestive of low fecundity and indicating a need for further diagnosis and treatment. Many diagnostic tests only have screening value and the only gold standards are hysteroscopy and laparoscopy. Severely impaired semen quality should lead to andrological work-up. Postcoital test and endometrial biopsy are obsolete. Treatment should preferably be aetiological, such as in anovulation, and sometimes also in endometriosis and tubal infertility. Primary treatment of male infertility is not proven to be advantageous. Conception-enhancing techniques such as intrauterine insemination (IUI), in vitro fertilisation (IVF) with or without intracytoplasmic sperm injection (ICSI), have shown to be effective. As a rule, and where possible, IUI is preferred and only if four to six cycles have failed should IVF be offered.
