Glossary
Human Chorionic Gonadotropin (HCG)
The hormone produced in early pregnancy that keeps the corpus luteum producing progesterone. Also used via injection to trigger ovulation after some fertility treatments, and used in men to stimulate testosterone production.
Hypogonadism
Inadequate ovarian or testicular function as shown by low sperm production or lack of follicle production, as well as low or absent levels of FSH and LH.
Hysteroscopy
A visual examination of the uterus using an instrument called a hysteroscope, which enables the doctor to see into the organ without making a large incision.
Implantation (Embryo)
The embedding of the embryo into tissue so it can establish contact with the mother's blood supply for nourishment. Implantation usually occurs in the lining of the uterus however, in an ectopic pregnancy it may occur elsewhere in the body.
In Vitro Fertilization (IVF)
Eggs produced by administering fertility drugs are retrieved from the woman's body and fertilized by sperm in a laboratory. The resulting embryos are transferred by catheter to the uterus.
In Vitro Maturation (IVM)
A revolutionary fertility treatment IVM, was developed as a safer and more affordable alternative to conventional IVF. IVM treatment collects immature eggs from unstimulated or minimally stimulated ovaries under ultrasound scan guidance after a shortened hormone treatment. These immature eggs are then matured in the laboratory for 24-48 hours using culture medium and small quantities of hormones. Finally, intracytoplasmic sperm injection (ICSI) is used for fertilization of the matured eggs. The resulting embryos are then finally transferred to a women's womb. \r\n\r\nIVM benefits: patients with PCOS due to increased risk of OHSS budget conscious younger women with normal menstrual cycles females diagnosed with cancer prior to chemotherapy or radiotherapy salvaging immature eggs collected during a standard IVF/ICSI.\r\n
Infertility
The inability to conceive after a year of unprotected intercourse (six months if the woman is over age 35) or the inability to carry a pregnancy to term.
Intracytoplasmic Sperm Injection (ICSI)
A micromanipulation (occurring under the microscope) procedure in which a single sperm is injected directly into the egg to enable fertilization with very low sperm counts or with non-motile sperm (sperm that don't swim effectively toward the egg). The embryo is then transferred to the uterus.
