Correlation between pregnancy outcomes and concentrations of progesterone,interleukin-4 and interferon-γin gestation period after artificial insemination
Objective:To explore the relationship between pregnancy outcomes and serum levels of progesterone(P),γ-interferon(IFN-γ) and interleukin-4(IL-4) and pregnancy outcomes in cycles of artificial insemination(AI) in order to determine the security and the rationality of luteal support.Methods:Serum levels of P,IFN-γ and IL-4 were measured at different time points(in the early follicular phase,during ovulation and embryo implantation,during the first and second trimesters) in 190 pregnant women with a total of 7...
