Study of time to pregnancy prognostic factors

“Study of time to pregnancy prognostic factors”. The aim of the study was to investigate the relation between various factors and female fecundity, which was expressed as time to pregnancy (TTP) and to create prognostic models. Tasks of the study were: 1.Estimate the relation between socioeconomic, demographic, life-style, environmental and job-related factors and time to pregnancy; 2.Create prognostic valuation model for the most important social, demographic, life-style, environmental and job-related factors what are associated with 12 month or longer time to pregnancy; 3.Estimate the impact of FSH receptor gene polymorphism variant on time to pregnancy; 4.Create prognostic model for the most important factors what are associated with 12 month or longer time to pregnancy under the influence of FSH receptor gene polymorphism. We established, that the most important independent risk factors prognoses time to pregnancy of 12 or more months in women analyzed for FSH receptor gene polymorphism group were older age, having gynecological diseases or fertility problems in the past, the use of contraception prior to conception and SER/SER polymorphism variant, what increased the probability of conceiving after 12 or more months 1.95, 1.57, 2.21, 1.87 and 1.68 times respectively
