Artificial
Insemination Is a technique involving the artificial insertion of
sperm-containing semen from a male into a female uterus to cause
pregnancy. There are two methods for AI: 1) Cervical insemination
- for this technique, the sperm is placed in a cap that fits over
the women's cervix (opening to the womb). The sperm can be placed
in this way without any special preparation. This keeps the sperm
in place until the cap is removed, and avoids the natural spillage
that occurs after intercourse. 2) Intrauterine insemination (IUI)
- for this technique, the sperm is separated in the laboratory from
the seminal fluid (white coloured liquid), and then inserted directly
into the uterus, bypassing the cervix (opening to the womb). This
prevents spillage and inability of the sperm to pass through the
cervical mucus. When the man has a low sperm count, it allows more
sperm to "get to" the egg. It does not however guarantee
that the sperm fertilizes an egg.
Artificial
insemination (AI) has a long history and is much less "high-tech"
than some other methods of assisted conception. In AI, semen is
introduced into the woman's uterus at around the time of ovulation,
with the aim of getting the sperm nearer to the egg. It can help
couples where the man has a low sperm count, or where the sperm
are unable to get through the woman's cervical mucus. Because sperm
is placed directly inside the woman, AI can help couples who are
unable to have intercourse because of disability, injury, or difficulties
such as premature ejaculation.
Your
doctor may prescribe fertility drugs to induce ovulation. These
can improve your chances of becoming pregnant, either by making
a woman's cycles regular, when they are irregular, or by inducing
more than one follicle to develop to increase the probability of
one fertilizing. Fertility drugs can have some side effects (LINK),
and they can slightly increase your chance of twins, and very rarely
more. You'll start taking the drug near the beginning of your menstrual
cycle to stimulate your ovaries to develop mature eggs for fertilization.
This
procedure may be an effective solution for men with a low sperm
count or poor sperm motility, where the sperm can't make the long
journey to the egg. It's also a good treatment option for couples
who have problems because the man's sperm can't get through the
woman's cervical mucus, perhaps because of an immune reaction. It
can only work for couples where the woman has one or both fallopian
tubes open. Donor sperm can be used in cases where the man is producing
no sperm at all, for single women or for same sex couples.
