Commonly used terms in Fertility: An encyclopaedia
IVF stands for in vitro fertilization, and is where an egg and sperm
are fertilised outside of the body in a glass dish, and placed back in the
woman’s uterus.
This treatment is recommended if a woman’s fallopian tubes are
damaged, there is unexplained infertility or for older women whose eggs have started to
deteriorate.
GIFT stands for gamete intrafallopian
transfer. In this procedure the sperm and egg and mixed, then placed back in
the body to fertilize naturally. GIFT is often used if the man has a low sperm count, or where ovulatory disorders
and cervical conditions are causing infertility. GIFT is only suitable for
women with healthy fallopian tubes.
ZIFT stands for zygote intra-fallopian
transfer, and is much the same as GIFT, except that a very young embryo is
transferred to the fallopian tube.
SUZI stands for subzonal insemination. A
single sperm is placed beneath the zona pellucida (the protein shell which
surrounds the egg) and can be a great benefit to men with a low sperm count or
have high percentages of sperm with abnormalities or a sperm blockage.
MIST stands for micro-insemination sperm
transfer and is similar to SUZI.
ICSI stands for intracytoplasmic sperm
injection. This technique involves selecting a single sperm and injecting it
directly into the egg. It is often used if the man experiences low sperm count,
sperm abnormalities and blockages. MESA
stands for micro-epididymal sperm aspiration. This involves sperm being
surgically extracted from the epididymis and is usually for men who have no
sperm in their ejaculate.
TESE stands for testicular sperm extraction
and is the same as MESA, except the sperm is collected from the testis.
