Physical and Sedentary Activities in Association with Reproductive Outcomes among Couples Seeking Infertility Treatment: A Prospective Cohort Study. Int J Environ Res Public Health. 2021 Mar 8;18(5):27181661-7827http://hdl.handle.net/10668/4452Background: The aim of this study was to investigate the association of physical activity (PA) with assisted reproductive technology (ART) treatment and pregnancy outcomes among couples seeking infertility treatment. Methods: This prospective cohort study was carried out among 128 infertile individuals (64 couples), entering the infertility clinic for ART procedures. Baseline PA (before entering any treatment) was assessed using accelerometry for both women and men. For every couple the infertility treatment outcomes were recorded. Results: The couples that required invasive ART procedures such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) spent less time in vigorous PA (−73 min/week per couple, woman + man) than those couples who became spontaneously pregnant after entering the study (p = 0.001). We observed no significant associations between the time spent in physical activities and positive pregnancy test or live birth. Conclusions: Our results do not support a positive nor negative relation between the time the couples spent in physical activities and the chances of getting pregnant or having a baby among patients seeking infertility treatment. However, couples undergoing invasive ART procedures did less vigorous PA than couples that became spontaneously pregnant, suggesting that PA may interfere with their reproductive health.enAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/ExerciseInfertilityReproductive healthReproductive techniquesAssistedSedentary behaviorIntracytoplasmic sperm injectionLive birthPregnancy outcomeIn vitro fertilizationEjercicio físicoInfertilidadSalud reproductivaTécnicas reproductivasTécnicas reproductivas asistidasConducta sedentariaInyecciones de esperma intracitoplasmáticasNacimiento vivoResultado del embarazoFertilización In vitroMedical Subject Headings::Check Tags::FemaleMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Therapeutics::Reproductive Techniques::Reproductive Techniques, Assisted::Fertilization in VitroMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Check Tags::MaleMedical Subject Headings::Phenomena and Processes::Reproductive and Urinary Physiological Phenomena::Reproductive Physiological Phenomena::Reproductive Physiological Processes::Reproduction::PregnancyMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Therapeutics::Reproductive Techniques::Reproductive Techniques, AssistedMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Therapeutics::Reproductive Techniques::Reproductive Techniques, Assisted::Fertilization in Vitro::Sperm Injections, IntracytoplasmicMedical Subject Headings::Diseases::Female Urogenital Diseases and Pregnancy Complications::Female Urogenital Diseases::Genital Diseases, Female::InfertilityMedical Subject Headings::Phenomena and Processes::Reproductive and Urinary Physiological Phenomena::Reproductive Physiological Phenomena::Reproductive Physiological Processes::Reproduction::Pregnancy::Pregnancy Outcome::Live BirthMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Prognosis::Pregnancy OutcomeMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Study Characteristics as Topic::Epidemiologic Studies::Cohort Studies::Longitudinal Studies::Prospective StudiesMedical Subject Headings::Health Care::Population Characteristics::Health::Reproductive HealthMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Prognosis::Treatment OutcomeMedical Subject Headings::Anthropology, Education, Sociology and Social Phenomena::Human Activities::ExerciseMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Clinical Laboratory Techniques::Pregnancy TestsMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Accelerometryresearch article33800259Acceso abierto10.3390/ijerph180527181660-4601PMC7967443
