  • a

  • Arcuate uterus
    A variant of the normal uterus for some experts, classified by others as a septate uterus.
  • b

  • Bicornuate uterus
    A common uterine abnormality that is characterized by the formation of two uterine cavities. The uterus has a V shape instead of the inverted pear shape.
  • Blastocyst
    The development stage of an embryo 5 to 7 days after fertilization.
  • c

  • Corpus luteum
    Formed from the follicle that has just released a mature ovum (or egg). It secretes oestrogen and progesterone, which are both necessary for the proper course of pregnancy.
  • Cryopreservation
    A conservation process where cells, embryos or tissues are preserved by cooling to very low temperatures (-196°C) for use in the future.
  • d

  • DNA
    (deoxyribonucleic acid): Found in chromosomes, it carries an individual’s genetic information.
  • e

  • Ejaculate
    The semen discharged during ejaculation.
  • Embryo
    An organism in its first stages of development, created from the fertilization of the oocyte by the sperm cell, during the period up to the 8th week of pregnancy
  • Endometrial cycle
    (or Uterine) : This cycle prepares the endometrium to receive the embryo in the event of fertilization. The start of the uterine cycle occurs with menstruation.
  • Endometriosis
    The abnormal growth of cells that make up the uterine lining.
  • Endometrium
    The mucous membrane lining the internal wall of the uterus.
  • Endovaginal ultrasound
    A medical imaging technique in which an ultrasonic probe is placed into the vagina to examine the uterus and ovaries.
  • Epididymis
    A duct located behind the testes. It allows for the conservation, maturation and transportation of sperm outside the body during ejaculation.
  • f

  • Fertility preservation
    Freezing or cryopreservation of gametes (eggs or sperm) to use in the future.
  • Follicles
    Located inside the ovaries, these tiny pockets of fluid contain the ova (or eggs).
  • g

  • Gamete
    A reproductive cell. The egg in women and the sperm in men.
  • Gonadotropin hormones
    Hormones secreted by the pituitary gland, acting on the ovarian functions (i.e. LH – luteinizing hormone and FSH – follicle-stimulating hormone).
  • h

  • Hormones
    Chemical messengers secreted by certain specialized glands. They influence the functioning of organs located in other areas of the organism.
  • m

  • Microdeletion
    A genetic mutation characterized by the deletion of genetic material on a chromosome.
  • o

  • Oocyte
    (or ovum): A female reproductive cell contained in an ovary.
  • Ovarian cycle
    A series of biological events that take place each month in one of the two ovaries. The objective is to produce a mature oocyte.
  • Ovarian hormones
    The hormones secreted by the ovaries: oestrogen, progesterone and inhibin.
  • Ovarian hyperstimulation syndrome
    Complication related to the injection of hormones intended to stimulate ovulation in order to collect eggs.
  • Ovulation induction
    The stimulation of ovulation by medication in women who usually do not ovulate.
  • Ovum
    (or oocyte): A female reproductive cell contained in an ovary.
  • p

  • Pelvis
    (adj. pelvic): The lower part of the trunk, including the lower abdomen and genital area.
  • Polycystic ovary syndrome
    Caused by a hormonal imbalance in women, this syndrome is characterized by irregular menstrual periods, increased facial and body hair, and the presence of acne. Numerous immature follicles are visible using ultrasound.
  • s

  • Seminogram
    (or spermiogram) : Microscopic analysis of the sperm to evaluate mobility, concentration and the general condition of sperm.
  • t

  • Thrombosis
    The formation of a blood clot in a vein or artery.
  • u

  • Unicornuate uterus
    A uterus that has a single fallopian tube and therefore a single ovary, instead of two.
  • Uterine fibroids
    Benign (non-cancerous) tumours located on the wall of the uterus.
