Abstract
Background Observational studies have explored the impact of iron homeostasis on infertility; however, establishing definitive causal relationships remains challenging. This study utilized a two-sample Mendelian randomization approach to investigate the potential causal relationship between iron status and infertility. Materials and methods Four indicators of iron status-serum iron, ferritin, transferrin saturation, and total iron binding capacity, were considered as exposure factors. Infertility was the outcome variable for both men and women. Robust causality was assessed using the primary inverse-variance-weighted method, complemented by three supplementary Mendelian randomization approaches. Sensitivity analyses were performed to enhance the precision and reliability of the results. Results No statistically significant associations were identified between the four indicators of iron status and infertility. These results remained consistent across multiple Mendelian randomization methodologies. Conclusion In conclusion, there is no evidence of a genetic causal relationship between iron status and infertility. Nevertheless, this does not preclude the possibility of a connection between iron status and infertility at different mechanistic levels.

Abstract
Asthma is a prevalent chronic respiratory condition affecting a significant portion of women of reproductive age. While the impact of asthma on general health and well-being has been extensively studied, its association with fertility challenges in women remains an area of growing concern. This review article explores the complexities surrounding fertility challenges in asthmatic women, specifically focusing on pregnancy loss, infertility, and the utilization of assisted reproductive technologies (ARTs). Various factors contribute to the heightened risk of pregnancy loss in asthmatic women, including the systemic inflammation associated with asthma, suboptimal asthma control, medication usage, and comorbidities. The review highlights the need for multidisciplinary management approaches to optimize asthma control before and during pregnancy, reducing the risk of adverse pregnancy outcomes. Furthermore, the review investigates the potential impact of asthma on female fertility and the underlying mechanisms involved. Asthma-related factors, such as chronic inflammation, altered hormonal balance, and medication effects, may disrupt the delicate reproductive processes, leading to infertility. It emphasizes the importance of comprehensive fertility evaluations and personalized treatment strategies for asthmatic women experiencing difficulties conceiving. Additionally, the article explores the utilization of ARTs, including in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI), in asthmatic women. It discusses the safety considerations and potential challenges associated with these techniques, such as the impact of asthma medications on oocyte quality, the effects of hormonal stimulation on asthma control, and the risk of exacerbations during the IVF process. The review underscores the importance of collaborative efforts among healthcare providers, including allergists, pulmonologists, obstetricians, and fertility specialists, to ensure optimal management of asthmatic women seeking to conceive. It emphasizes the significance of preconception counseling, meticulous asthma control, appropriate medication management, and individualized fertility treatments to enhance the reproductive outcomes in this population.

Abstract
Objective We investigate symptoms of anxiety and depression among women with asthma prior to fertility treatment. Methods This is a cross-sectional study of women screened for eligibility to the PRO-ART study (RCT of omalizumab versus placebo in asthmatic women undergoing fertility treatment (NCT03727971)). All participants were scheduled for in vitro fertilization (IVF) treatment at four public fertility clinics in Denmark. Data on demographics and asthma control (ACQ-5) were obtained. Symptoms of anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS-A and D, respectively) and defined as being present on both subscales if a score >7 was obtained. Spirometry, diagnostic asthma test, and measurement of fractional exhaled nitric oxide (FeNO) were conducted. Results A total of 109 women with asthma were included (mean age 31.8 ± 4.6 and BMI 25.5 ± 4.6). Most women had male factor infertility (36.4%) or unexplained infertility (35.5%). Twenty-two percent of the patients reported uncontrolled asthma (ACQ-5 score > 1.5). The mean HADS-A and HADS-D scores were 6.0 ± 3.8 (95% CI 5.3-6.7) and 2.5 ± 2.2 (95% CI 2.1-3.0), respectively. Thirty (28.0%) women reported anxiety symptoms, and four (3.7%) had concomitant depressive symptoms. Uncontrolled asthma was significantly associated with both depressive (p = 0.04) and anxiety symptoms (p = 0.03). Conclusions More than 25% of women with asthma prior to fertility treatment had self-reported symptoms of anxiety, and just below 5% had self-reported depressive symptoms, possibly related to uncontrolled asthma.

Abstract
Asthma is a heterogeneous inflammatory disease characterized by abnormalities in immune response. Due to the inherent complexity of the disease and the presence of comorbidities, asthma control is often difficult to obtain. In asthmatic patients, an increased prevalence of irregular menstrual cycles, infertility, obesity, and insulin resistance has been reported. Given that these conditions are also common in patients with polycystic ovary syndrome (PCOS), we propose the definition of "asthma-PCOS overlap syndrome" to indicate a medical condition which shares characteristics of both diseases. The aim of this review is to analyze the links between asthma and PCOS and evaluate the therapeutic role of myo-inositol, a natural compound currently utilized in patients with PCOS, in the management of asthma patients.

Abstract
Asthma is the commonest chronic medical condition encountered in pregnancy. Poor asthma control and exacerbations are frequently encountered due to treatment non-adherence, pregnancy-related aggravating factors such as increased susceptibility to viral infections, and comorbidities that are commonly associated. Asthma-related inflammatory reactions and placental effects, the effect of medications, and respiratory symptoms and hypoxia are probably to interact to result in an increased adverse obstetric outcomes including miscarriage, foetal congenital anomalies, pregnancy hypertensive disorders, gestational diabetes, preterm labour and birth, antepartum haemorrhage, low birthweight and foetal growth restriction (FGR), caesarean delivery, postpartum haemorrhage (PPH), maternal intensive care admission, and even mortality, while the offspring also has increased long-term morbidity. Interdisciplinary management with frequent assessment by symptoms, spirometry, and biomarkers, together with removal of risk factors such as smoking and appropriate instigation of treatment including short courses of systemic corticosteroid, could ensure optimal and tailored treatment to control symptoms, prevent exacerbations, and ultimately enhancing maternal and perinatal outcomes.

Abstract
STUDY QUESTION Is the chance of childbirth, and risk of infertility, pregnancy loss and need for assisted reproduction different for women with asthma compared to women without asthma? SUMMARY ANSWER Women with asthma had comparable chances of giving birth compared to the reference population, however, their risk of both infertility and pregnancy loss, as well their need for medically assisted reproduction, was higher. WHAT IS KNOWN ALREADY Reproductive dysfunction has been reported among women with asthma, including longer time to pregnancy, increased risk of pregnancy loss and a higher need of medically assisted reproduction, but their risk of clinical infertility is unknown. STUDY DESIGN, SIZE, DURATION This longitudinal register-based cohort study included all women with a healthcare visit for delivery, infertility, pregnancy loss or induced abortion in the southernmost county in Sweden, over the last 20 years. PARTICIPANTS/MATERIALS, SETTING, METHODS Using the Skåne Healthcare Register, we identified all women aged 15-45 between 1998 and 2019, who received a diagnosis of asthma before their first reproductive outcome (n = 6445). Chance of childbirth and risk of infertility, pregnancy loss and assisted reproduction were compared to a healthcare seeking population of women without any asthma (n = 200 248), using modified Poisson regressions. MAIN RESULTS AND THE ROLE OF CHANCE The chance of childbirth was not different between women with asthma versus those without, adjusted risk ratio (aRR) = 1.02, 95% CI: 1.01-1.03. The risk of seeking care for infertility was increased, aRR = 1.29, 95% CI: 1.21-1.39, and women with asthma more often needed assisted reproduction aRR = 1.34 95% CI: 1.18-1.52. The risk of suffering a pregnancy loss was higher, aRR = 1.21, 95% CI: 1.15-1.28, and induced abortions were more common, aRR = 1.15, 95% CI: 1.11-1.20, among women with asthma. LIMITATIONS, REASONS FOR CAUTION The study was an observational study based on healthcare visits and lacked detailed anthropometric data, thus residual confounding cannot be excluded. Only women with a healthcare visit for a reproductive outcome were included, which cannot be translated into pregnancy intention. A misclassification, presumed to be non-differential, may arise from an incorrect or missing diagnosis of asthma or female infertility, biasing the results towards the null. WIDER IMPLICATIONS OF THE FINDINGS This study points towards reproductive dysfunction associated with asthma, specifically in regards to the ability to maintain a pregnancy and the risk of needing medically assisted reproduction following clinical infertility, but reassuringly the chance of subsequently giving birth was not lower for these women. STUDY FUNDING/COMPETING INTEREST(S) This article is part of the ReproUnion collaborative study, co-financed by EU Interreg ÖKS, Capital Region of Denmark, Region Skåne and Ferring Pharmaceuticals.

Abstract
BACKGROUND Women with asthma appear to have an increased risk of pregnancy loss (PL). The impact of asthma on recurrent pregnancy loss (RPL), defined as 3 consecutive losses, is, however, unknown. OBJECTIVE The aim of this study was to investigate whether having asthma before or during the fertile age is associated with PL and RPL. METHODS Based on Danish national health registers, we identified all women aged 6 to 45 years with at least 2 filled prescriptions of an antiasthma drug during the period 1977 to 2019. Women with asthma were compared with women without asthma. Pregnancy outcomes were retrieved for both groups from national health registers. Logistic regression with adjustment for the year of birth and educational level provided odds ratios (ORs) for the number of PLs. Subgroup analyses were conducted for early-onset (age 6-15 years), adult-onset (age 16-39 years), and late-onset (age 40-45 years) asthma. Lastly, we compared uncontrolled asthma (defined as ≥ 400 doses of a short-acting beta-2 agonist in a year) to controlled asthma (defined as < 400 doses of a short-acting beta-2 agonist in a year). RESULTS In a population of 1,309,786 women, we identified 128,553 women with asthma and 1,297,233 women without asthma. Compared with nonasthmatic women, women with asthma had ORs for 1, 2, and 3 or more PLs of 1.05 (95% CI 1.03-1.07), 1.09 (95% CI 1.05-1.13), and 1.18 (95% CI1.11-1.24), respectively, and for RPL of 1.19 (95% CI 1.12-1.27). In women with early-onset asthma, the OR of 3 or more PLs was 1.47 (95% CI 1.24-1.72). For women classified as having uncontrolled asthma compared with controlled asthma, we found a significant OR of 1.60 (95% CI 1.16-2.16) for 3 or more PLs. CONCLUSIONS We found a significant positive association between asthma and number of PLs and RPLs. Early-onset asthma and uncontrolled asthma were more strongly associated with PL than adult-onset and late-onset asthma and controlled asthma.

Abstract
Asthma and infertility are the most common disorders among women of reproductive age. Time to pregnancy is prolonged in women with asthma, and importantly, age seems to be a more important risk factor regarding fertility in women with asthma compared to women without asthma. Some data have shown a higher frequency of miscarriages in women with asthma, although the data are conflicting on this issue as studies have observed no association between asthma and pregnancy loss. Furthermore, studies have shown no negative effect of asthma on the total number of offspring. Pregnancy may, thus, have a significant impact on women with asthma, as well as on their offspring.The age of the women has an important impact on ability to conceive, but also for the pregnancy itself, with higher risk of uncontrolled asthma as well as asthma exacerbations with increasing age. Well-controlled asthma decreases the risk of maternal and fetal complications, while poorly controlled and undertreated asthma is associated with a range of risks for both mother and fetus. Asthma treatment should follow the general guidelines for asthma therapy, irrespective of pregnancy status, including treatment with inhaled corticosteroids, β2-agonists and muscarinic antagonists. Targeted treatment with biologics for severe asthma seems to be without important adverse effects. The use of systemic corticosteroids may be associated with adverse events during the first trimester; however, an exacerbation with the associated risk of hypoxaemia is worse for the fetus. Best possible asthma control may be achieved using repeated measurements of fractional exhaled nitric oxide (FENO), as the use of FENO compared with symptoms registration only has been shown to reduce exacerbation rate.In conclusion, women with asthma should be encouraged to conceive at an early age, might experience miscarriages, but the number of offspring are the same as in women without asthma. Well treated asthma is important for the well-being of both the mother and the unborn fetus.

Abstract
A potential correlation between polycystic ovary syndrome (PCOS) and asthma, used to be identified as diseases originating from two independent systems, has been supported by increasing evidence. From an epidemiological perspective, mounting studies have confirmed that women suffering from PCOS exhibit increased susceptibility to asthma. Meanwhile, PCOS and asthma seem to share several mutual pathological conditions, such as metabolic disorders, hormonal fluctuation, proinflammatory state, etc. Here, we further elucidate the correlation between asthma and PCOS by focusing on the internal common pathophysiology and adverse influences on women's health. Understanding the internal connection between PCOS and asthma may shed light on developing new prevention and control strategies to fight against these conditions.

Abstract
İNTRODUCTION Asthma is one of the most common chronic airway disease among reproductive period of women. Chronic inflammation in asthma, eosinophilia, high steroid treatment and uncontrolled asthma may cause infertility by affecting the reproductive organs, menstrual cycle and quality of life. Some patients with severe asthma have frequent exacerbations associated with persistent eosinophilic inflammation despite continuous treatment with high-dose inhaled glucocorticoids with or without oral glucocorticoids. Mepolizumab (anti-IL-5) is a succesful option of treatment. CASES First case; 25-year-old female patient has been diagnosed having asthma and rhinitis for 5 years. Even she had desired pregnancy for 3 years, she was unable to have a baby, and had been diagnosed having primary infertility. Second case; 36 years old female had rhinitis for 6 years and asthma for 4 years Although she used the same contraception method (withdrawal,condom) for years, she did not get pregnant until receiving the second dose of mepolizumab treatment. RESULT Two women were treated with mepolizumab for eosinophilic severe asthma and they got pregnant. CONCLUSION Unexplained infertility in people with severe eosinophilic asthma may be corrected by mepolizumab treatment. However, there is not enough data regarding the use of mepolizumab during pregnancy.

Abstract
AIM To update obstetric care providers about asthma management. SUMMARY Asthma is the most frequent comorbid chronic illness in pregnancy. Convincing evidence shows that uncontrolled asthma magnifies the risk of maternal, fetal and neonate complications. Unfortunately, one in four women take no inhaler during pregnancy, and it is likely that decreased adherence, rather than changes in pathology, explains uncontrolled maternal asthma. Patient surveys reveal a need for information and reassurance. Although some molecules are preferred in pregnancy, there is currently no basis to withhold any asthma medication - old or new. Biomarkers such as blood eosinophils and fractional exhaled nitric oxide are an effective way to assess the risk of asthma attacks and the likelihood of responding to inhaled steroids. Furthermore, practice-changing trials in mild asthma show that switching reliever-only regimens to as-needed 'controller-and-reliever' therapy is effective. We suggest that applying these changes can alleviate women's concerns and improve outcomes.

Abstract
This study assessed the rate of primary infertility and its associated factors among 402,807 currently married women aged 20-49 years in India using National Family Health Survey-4 data collected in 2015-2016. Dietary patterns and selected morbidities were included as independent variables, and socioeconomic variables were considered as covariates. Bivariate and multivariate analyses were done to estimate the prevalence of primary infertility and assess its association with the selected variables, respectively. The rate of primary infertility among currently married women in India in 2015-16 was 1.9% and this was significantly associated with younger age (<35 years), higher age at marriage (≥18 years), urban residence, higher secondary or above education and poverty. The consumption of dairy products (OR = 0.79, CI = 0.73-0.86), dark green leafy vegetables (OR = 0.57, CI = 0.39-0.81) and fruit (OR = 0.88, CI = 0.77-1.01) significantly reduced the odds of primary infertility. Daily consumption of fish and aerated drinks was related to 1.06-1.21 times higher odds of primary infertility. Overweight/obesity, high blood pressure and high blood glucose levels were associated with 1.08-1.21 times elevated odds of primary infertility. Thyroid disorder (OR = 1.38, CI = 1.21-1.60), heart disease (OR = 1.17, CI = 1.16-1.19) and severe anaemia (OR = 1.24, CI = 1.00-1.53) were associated with an increased likelihood of primary infertility among women (OR 1.17-1.39, CI 1.00-1.60). The findings provide compelling evidence that primary infertility among women is related to dietary patterns and morbidities. Interventions and programmes targeting the promotion of healthy diets and lifestyles could be beneficial in addressing the issue of primary infertility among women.

Abstract
The European Respiratory Society (ERS) accepted 4062 abstracts for presentation at the ERS International Congress in 2020. Although the conference was held virtually, making it possible to replay presentations, it remains a challenge to keep abreast of all the clinical and scientific advances. Therefore, this article provides highlights from the General Pneumology Assembly. Selected presentations from rehabilitation and chronic care, general practice and primary care, and electronic/mobile health (e-health/m-health) are summarised. The highlights incorporate novel findings from laboratory-based science, randomised controlled trials and qualitative research together with insights from newly available clinical guidelines.

Abstract
INTRODUCTION Asthma is associated with prolonged time to pregnancy and a higher need for fertility treatment. However, the mechanism underlying this association remains incompletely understood. Previous research points to asthma-driven systemic inflammation also affecting the reproductive organs and thereby fertility. The aim of this study was to determine if treatment with omalizumab prior to fertility treatment will increase pregnancy rate among women with asthma by decreasing the systemic asthma-related inflammation and, by that, to provide insight into the underlying mechanisms. METHODS AND ANALYSIS This is an ongoing prospective multicentre randomised controlled trial planned to enrol 180 women with asthma recruited from fertility clinics in Denmark. The patients are randomised 1:1 to either omalizumab or placebo. The primary endpoint is the difference in pregnancy rate confirmed with ultrasound at gestational week 7 of pregnancy. The secondary endpoints are change in sputum and blood eosinophil cell count, change in biomarkers, change in microbiota, together with rate of pregnancy loss, frequency of malformations, pre-eclampsia, preterm birth, birth weight, small for gestational age and perinatal death between groups. ETHICS AND DISSEMINATION The methods used in this study are of low risk, but if successful, our findings will have a large impact on a large group of patients as infertility and asthma are the most common chronic diseases among the young population. The study has been approved by the Ethics Committee-Danish national research ethics committee (H-18016605) and the Danish Medicines Agency (EudraCT no: 2018-001137-41) and the Danish Data Protection Agency (journal number: VD-2018486 and I-Suite number 6745). The test results will be published regardless of whether they are positive, negative or inconclusive. Publication in international peer-reviewed scientific journals is planned. TRIAL REGISTRATION NUMBER NCT03727971.

Abstract
Purpose Asthma has been positively associated with irregular menses and infertility in some studies, but data are limited on the relation between asthma medication use and fecundability (i.e., average per-cycle probability of conception among non-contracepting couples). This study examines the extent to which a history of asthma, asthma medication use, and age at first asthma diagnosis are associated with fecundability among female pregnancy planners. Participants and Methods Pregnancy Study Online (PRESTO) is an ongoing, web-based preconception cohort study of couples aged 21–45 years from North America. Between July 2013 and July 2019, a total of 10,436 participants enrolled in PRESTO, and 8286 were included in the present analysis. At study enrollment, women reported whether they had ever been diagnosed with asthma and, if so, the year they were first diagnosed. Women who reported ever being diagnosed with asthma were asked about medication use, including medication type and frequency of use. Participants completed follow-up questionnaires every 8 weeks for up to 12 months or until pregnancy. Proportional probabilities regression models were used to estimate fecundability ratios (FRs) and 95% confidence intervals (CIs), adjusting for potential confounders. Fecundability ratios below 1.00 indicate reduced probability of conception. Results There was little association between a history of asthma diagnosis or asthma medication use and fecundability. Compared with no history of asthma, the FR for ever-diagnosis of asthma with medication use was 1.02 (95% CI: 0.91–1.15) and for ever-diagnosis of asthma without medication use was 1.00 (95% CI: 0.91–1.09). Highest intensity asthma medication use (daily plus extra dosing for symptoms), combination inhaled corticosteroid and long-acting beta-agonist inhaler use, and a first diagnosis of asthma after age 17 years were associated with small reductions in fecundability. Conclusion The present study provides little evidence that asthma or asthma medication use is adversely associated with fecundability.

Abstract
Background Asthma has been linked with prolonged time to pregnancy compared to healthy controls, also asthma has been linked to a higher need for fertility treatment. However, knowledge of the possible association between allergy and need for fertility treatment is limited. Our aim was to explore a possible difference in having had fertility treatment in women with asthma and live births in those with perennial allergy (animals, fungi and dust mites) compared to no allergy/seasonal allergy. The primary outcome of interest was fertility treatment. Patients and Methods Women enrolled in the Management of Asthma during Pregnancy (MAP) program at Hvidovre Hospital, DK, were included in the present analysis provided they fulfilled the following criteria: 1) diagnosed with asthma and current anti-asthma therapy and 2) first visit to the respiratory outpatient clinic within the first 18 weeks of pregnancy. Participants were divided into two groups: asthma with perennial allergy (cases) and asthma with seasonal/no allergy (controls). Logistic regression analysis was applied, and findings expressed as odds ratios (OR). Results Among women with asthma and perennial allergy (n=544 cases), 13.8% (n=75) had fertility treatment, compared to only 10.1% (n=39) among women with asthma and seasonal/no allergy (n=388, controls) (OR 1.43, 95% CI 0.95–2.16, p=0.087). This association remained statistically insignificant after adjusting for confounders, including BMI (OR 1.19, 95% CI 0.77–1.84, p=0.433). In women ≥35 years of age, 28% (n=44) and 20% (n=19), respectively, among cases and controls had fertility treatment (OR 1.60, 95% CI 0.87–2.94, p=0.132), and likewise, statistically insignificant after adjusting for confounders (OR 1.41, 95% CI 0.74–2.69, p<0.293). Conclusion In women with asthma and live births, our study revealed a trend towards an association between perennial allergy and a higher need for fertility treatment compared to seasonal/no allergy.

Abstract
This European Respiratory Society/Thoracic Society of Australia and New Zealand statement outlines a review of the literature and expert opinion concerning the management of reproduction and pregnancy in women with airways diseases: asthma, cystic fibrosis (CF) and non-CF bronchiectasis. Many women with these diseases are now living into reproductive age, with some developing moderate-to-severe impairment of lung function in early adulthood. The statement covers aspects of fertility, management during pregnancy, effects of drugs, issues during delivery and the post-partum period, and patients' views about family planning, pregnancy and parenthood. The statement summarises current knowledge and proposes topics for future research, but does not make specific clinical recommendations.

Abstract
PURPOSE OF REVIEW Asthma, a common respiratory disease that affects about 10% of the US population, represents a significant public health issue. In the last decade, cumulative evidence has demonstrated sex disparities in asthma, including significant differences in epidemiology, clinical presentation, response to therapies, and health outcomes. Understanding sex-related differences in asthma enables clinicians to provide personalized asthma care and improve asthma outcome. RECENT FINDINGS Recent studies on sex-related differences in asthma inform us on mechanism underlying asthma pathogenesis across all age groups. Sex hormones directly modulate immune pathways crucial in asthma pathogenesis and affect individual's response to environmental triggers and medications, such as leukokotriene inhibitors. Not surprisingly, the use of external sex hormone supplementations appears to modulate asthma risk. Identification of sex-specific asthma risk loci through genome-wide association studies also provides supporting evidence on sex-related differences in asthma. There is an interaction between sex and obesity, an interaction that could place females at higher risk for systemic inflammation and, consequently, asthma. In this article, we review epidemiological and clinical studies on sex-related differences in asthma, with a special focus on the role of sex hormones, including hormonal therapies and the asthma-obesity interaction.

Abstract
Background and objective Asthma is one of the most common chronic diseases among women of reproductive age, and previous studies have suggested a link between female asthma and infertility. The aim of the present review is to provide an update on current knowledge of the association between female asthma and/or atopy and a reduction in fertility, ie, number of offspring, time to pregnancy (TTP) and need for fertility treatment. Methods Systematic review performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-guidelines. Results A total of 14 studies fulfilled the predefined criteria for inclusion in the present review. Six studies investigated the association between female asthma and/or atopy and number of offspring, of which one reported a positive, two a negative, and three no association. Three studies addressed the association between asthma and TTP and found that TTP was significantly prolonged in asthmatic women compared to non-asthmatic women. Five studies investigated subfertility and the need for fertility treatments of which two studies found a higher prevalence of infertility among women prescribed anti-asthma medication. One study found no difference in the number of fertility treatments of asthmatic women compared to non-asthmatic women, whereas three studies reported that female asthma was associated with significantly more fertility treatment compared to non-asthmatic women. Conclusion Although the available evidence is conflicting, there is a clear trend toward an association between female asthma and a reduction in fertility, and by that a larger proportion requiring fertility treatment, even though female asthma might not negatively affect total number of offspring.

Abstract
Asthma has been linked with prolonged time to pregnancy. Our aim was to explore a possible association between asthma and need for fertility treatment among women with live births.All women enrolled in the Management of Asthma during Pregnancy (MAP) programme at Hvidovre Hospital, Denmark were each matched with the next three consecutive women giving birth at Hvidovre Hospital. Information from the Danish National Assisted Reproductive Technology (ART) registry was cross-linked with the Danish Medical Birth registry to identify live births. The primary outcome of interest was births following fertility treatment.Our sample comprised pregnancies from asthmatic mothers (n=932, described as "cases") and non-asthmatic mothers (n=2757, described as "controls"), with 12% (n=114) and 8% (n=212), respectively, having had fertility treatment (OR 1.67, 95% CI 1.32-2.13; p<0.001). This association remained statistically significant after adjusting for confounders, including body mass index (OR 1.31, 95% CI 1.00-1.70; p=0.047). In women ≥35 years, 25% of cases (n=63) and 13% of controls (n=82) received fertility treatment (OR 2.12, 95% CI 1.47-3.07; p<0.001), which also remained statistically significant after adjusting for confounders (OR 1.65, 95% CI 1.11-2.46; p=0.013).A higher proportion of the births from asthmatic mothers involved fertility treatment compared to non-asthmatic mothers, not least among women aged ≥35 years.

Abstract
Recent research suggests that women with polycystic ovary syndrome (PCOS) have a higher risk of asthma. However, the severity of asthma, use of antiasthma medication and effect on fertility have yet to be investigated. In a case–control cross-sectional registry study using the Danish National Patient Register and other Danish registries, asthma prevalence, asthma severity, antiasthma medication use and fertility outcome were investigated among two groups of women with PCOS (n=1358 and n=17 123) and a healthy control group (n=5340). Both asthma prevalence (OR 1.45, 95% CI 1.24–1.70) and mean daily inhaled corticosteroid dose were higher among women with PCOS compared with healthy controls, whereas asthma severity was the same in women with and without PCOS. Women with PCOS and asthma had more in vitro fertilisation treatments than women in the control group with asthma, but the numbers of children per woman and spontaneous abortions were the same. Women with PCOS have a higher prevalence of asthma and a higher use of inhaled corticosteroids, whereas asthma severity is the same in women with and without PCOS. Asthma is associated with more in vitro fertilisation treatments in women with PCOS. Asthma and PCOS are associated; asthma is associated with more in vitro fertilisation treatments in women with PCOShttp://ow.ly/BTmh30lTP20

[PMID: 27692138 DOI: 10.1016/j.rmed.2016.08.025] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2016] [Revised: 08/23/2016] [Accepted: 08/24/2016] [Indexed: 10/21/2022]
Abstract
Asthma may be associated with polycystic ovary syndrome (PCOS), and possibly patients with PCOS have a more severe type of asthma. The purpose of this systematic literature review is to summarize evidence of a coexistense of PCOS and asthma using the available literature. The search was completed on 01.01.2016. English language articles were retrieved using the search terms 'Asthma' AND 'PCOS', 'Asthma' AND 'systemic inflammation', 'Asthma' AND 'metabolic syndrome', 'asthma' AND 'gynaecology', 'PCOS' AND 'systemic inflammation', 'PCOS' AND 'metabolic syndrome', 'PCOS' AND 'allergy'. Five papers meeting prespecified search criteria were found of which two were registry studies of relevance. The current literature supports a coexistense of PCOS and asthma and gives us an indication of the causes for the possible link between PCOS and asthma. Further research in the area must be conducted to determine the exact nature and magnitude of the association.
