“…Many mechanisms have been proposed to cause fertility problems in endometriosis. These include altered folliculogenesis (Doody et al, 1988), leading to ovulatory dysfunction and low quality oocytes, as well as luteal phase defects (Grant, 1966), impaired fertilization (Wardle et al, 1985), and abnormal embryogenesis (Garrido et al, 2002), abnormalities in peritoneal fluid (Minici et al, 2008), eutopic endometrium and immunological abnormalities (Akoum et al, 2006). It seems that not one mechanism is responsible for the reduced fecundability in endometriosis it is rather a complex of several mechanisms rather than one mechanism.…”
