INTRA-UTERINE
INSEMMINATION AND GONADOTROPHIN THERAPY
This
is an infertility treatment suitable for couples with:-
1.
Unexplained infertility
2. Mild male factor problems
3. Immunological infertility
4. Cervical factor infertility
5. Some forms of sexual dysfunctions
Techniques of Treatment
1.
The female partner will be given fertility treatment to ensure that
she has at least 2 or 3 really good eggs. This comprises:
a)
clomiphene tablets 50-100 mg daily for 5 day and,/or
b) gonadotropin injections
2
Ultrasound scans are performed to ensure that the response of the
ovaries is adequate
3
Provided that the follicles are of appropriate size, an injection
of HCG (10,000 units) will be given by intramuscular injection This
injection causes maturation of the follicles and ovulation.
4
24-36 hours later, the male partner will be asked to provide a sample
of seminal fluid which will be prepared by a special technique,
to select out the healthiest and strongest swimming sperm.
5
The specially prepared semen sample will then be gently injected,
using a very fine plastic tube, through the cervix (mouth of the
uterus), into the upper part of the uterus, close to the opening
of the tubes. This procedure does not require any anaesthetic and
causes minimal discomfort.
6
This sperm will swim along the tube to meet the eggs, and hopefully
fertilisation of one or more of the eggs will occur.
7
The fertilized eggs then travel back along the tube and into the
uterus. Hopefully implantation will occur, leading to pregnancy.
Risks
and Side-Effects
The
use of fertility injections is associated with a small risk of causing
too many follicles to grow (hyperstimulation). This may result either
in multiple pregnancy, or in a condition called Ovarian Hyperstimulation
Syndrome (OHSS).
With
OHSS the ovaries become swollen, form cysts and very rarely, the
women may become very ill. In an attempt to minimise the risks of
causing these problems, it is usual to begin treatment with a low
dose of gonadotrophin therapy and always to count and measure the
follicles before giving the HCG (egg releasing) injection. If the
scan suggests that there may be too many very large follicles, the
HCG injection will NOT be given and you will be advised not to have
sexual intercourse.
Contra-Indications
This
treatment is not suitable for couples who are infertile due to:
a)
damage or blockage of the fallopian tubes
b) severe male factor problems (very low sperm counts)
c) significant endometriosis
This
form of treatment will not be effective if :
a)
there are not enough good quality eggs in the ovaries
b) if there are any adhesions which may cause the eggs to be trapped
c) if the fimbrial ends of the tubes are damages and are therefore
unable to collect the eggs after ovulation
d) if there is any significant damage to the tubes so that sperms
and eggs cannot travel freely along the tubes
e) if the sperm are very weak, and either not strong enough to swim
along the tube to meet the eggs, or are not strong enough to burrow
their way through the outer covering of the egg in order to bring
about fertilisation.
In
all these cases other forms of Assisted Reproduction would be the
treatment of choice.
Success
Rates
1.
1 pregnancy out of every 9 treatment cycles.
2. It is usually offered for 3-6 treatment cycles. If you fail to
become pregnant within the first 6 attempts, the likelihood of becoming
pregnant if you continue treatment, is very small, and should then
go ahead with other forms of Assisted Reproductive Techniques. (ART)
