Are pregnancies in patients with infertility history different than pregnancies conceived naturally?
There are many reasons why a couple is
infertile. Although we tend to categorize infertility according to various
causes (male factor, tubal factor, uterine anomalies, ovulatory dysfunction
etc.), the truth is that most couples cannot be classified into any unique
category. Instead, most couples suffer from multiple factors that are
responsible for their fertility problems. Over the years, we have found that
with a few exceptions, implantation problems are the most common reason for
infertility. In other words, most infertility patients conceive but the embryo
is lost due to intrinsic inability to implant into the uterine cavity. The
second most common is early miscarriage due to placental failure in the
earliest stages of pregnancy. Thrombophilic disorders are present in >98% or
infertility patients and in our experience the most important cause of
infertility and early pregnancy loss.
