Patients with Uterine Factor Infertility: General
Absolute uterine factor infertility (AUFI) refers to a type of infertility that is 100% attributable to the absence of a normal uterus, either anatomical or functional, which prevents the implantation of an embryo or the ability to carry a term pregnancy. Relative uterine factor infertility (RUFI) refers to uterine abnormalities whose presence can cause variable degrees of infertility or subfertility, although it is difficult to prove that such uterine abnormality is the major cause of infertility in each specific case. The group AUFI includes congenital pathologies such as uterine agenesis or hypoplasia and also acquired conditions such as hysterectomy post-partum or difficult-to-treat diseases like leiomyomas or neoplasia of the uterus. The group RUFI covers a broad spectrum of conditions in which the uterus is present, ranging from different degrees of uterine malformations to presence of conditions such as fibroids or even dysfunctional problems related to implantation failures.
