Introduction: Hysterectomy has been suggested to increase the risk of urinary incontinence (UI), although evidence is controversial. In our population-based cohort study, we aimed to assess the independent effect of hysterectomy on the risk of de novo UI.
Material And Methods: This is a population-based cohort study on the women of the Northern Finland Birth Cohort 1966 (n = 5889).
Study Question: Are there growth differences between singleton children born after frozen embryo transfer (FET), fresh embryo transfer (ET), and natural conception (NC)?
Summary Answer: Adolescent boys born after FET have a higher mean proportion and increased odds of overweight compared to those born after fresh ET.
What Is Known Already: Children born after FET have higher mean birthweights and an increased risk of large-for-gestational-age compared to those born after fresh ET and even NC. This raises questions about possible growth differences later in childhood.
Objective: To investigate whether there is an association between endometriosis and nongynecological diseases in the general female population by age 50?
Design: A prospective cohort study.
Setting: Study participants with and without endometriosis were identified from a general population-based birth cohort. The analyzed data, linking to the national hospital discharge registers, spanned up to the age of 50 years.
Study Question: Is the health of singletons born after frozen embryo transfer (FET) comparable to that of singletons born after fresh embryo transfer (ET) until early adulthood?
Summary Answer: The health of singletons born after FET does not differ from that of singletons born after fresh ET.
What Is Known Already: The differences in perinatal outcomes of children born after FET and fresh ET are well known. FET is associated with an increased risk of large-for-gestational-age but diminished risks of preterm birth (PTB), small-for-gestational-age and decreased perinatal mortality compared to fresh ET.
