This chapter defines infertility as the inability to conceive after twelve months of trying, noting a prevalence of 14% with secondary cases comprising at least half of these instances. It highlights that fecundability declines significantly with age and prior treatment history, dropping from 0.4 in 25-year-olds to 0.008 in those with unexplained infertility lasting two years. The text specifically notes that mean time to pregnancy exceeds seven years for women aged 35 undergoing donor insemination if they have previously received treatment for endometriosis. Relevance to endometriosis: mentioned only as a factor prolonging conception times in patients undergoing assisted reproductive technologies, while the paper's main focus is general infertility statistics and definitions.
