ECTOPIC PREGNANCYA pregnancy implanted outside the cavity of the womb; most often in the fallopian tube. This is also termed a tubal pregnancy. This can usually be diagnosed in its early stages by following the pregnancy hormone, βHCG, very closely during the early part of pregnancy. Left undiagnosed and untreated, an ectopic pregnancy can have serious medical consequences.
EGG RETRIEVALThe procedure during an IVF cycle where the oocytes (eggs) are harvested through a minimally-invasive surgical procedure. This is done under light anesthesia so that the women are sleeping during the entire process. Typically takes about 30 minutes total.
EMBRYOThe term used to describe the early stages of fetal growth. Strictly defined from the second to the ninth week of pregnancy, but often used to designate any time after conception.
EMBRYO TRANSFERThe procedure of transferring embryos back into the endometrial cavity (womb) of a woman during an IVF cycle. It occurs on the third or fifth day after an egg retrieval or on the appropriate day of a ‘frozen’ cycle.
ENDOMETRIAL BIOPSYThe extraction of a small piece of tissue from the endometrium (lining of the womb) for microscopic examination.
ENDOMETRIAL CAVITYThe space inside the womb that is created by its inner lining.
ENDOMETRIOSISThe presence of endometrial tissue (tissue that normally lines the womb) in abnormal locations such as the ovaries, fallopian tubes and abdominal cavity. These lesions lead to local irritation and inflammation that can cause scarring to occur which can bind-up pelvic organs to the point of dysfunction and pain.
ENDOMETRIUMThe inner lining of the womb that responds to female hormones during the menstrual cycle and treatment cycles. This lining, when properly prepared, forms the area of attachment and implantation of the embryo. A portion of this lining is shed each month with menstruation.
EPIDIDYMISThe portion of the male genital tract next to the testis where sperm maturation is partially accomplished. Receives sperm from the testis and continues as the ductus (vas) deferens.
ESTRADIOL (OR OESTRADIOL)The principal hormone produced by the growing ovarian follicle. It is frequently measured in the blood to gauge the strength and development of the follicles during treatment cycles.
