15 percent of the population is considered infertile. Infertility is
described as not having a baby after 6 months of unprotected
intercourse. Infertility is increasing in modern communities. In men
declines in sperm count due to toxic environment and possible
evolutionary effects are noted. Also women due to educational and
career concerns are married at a later age. Average menopausal age
ranges between 48 and 52 in women. We now know that, several years
before the menopause women are unable to bear children due to the
diminished ovarian function.
Historically,
the menopausal age did not change and the chance of having a baby is
very slim as the female approaches menopause. Therefore we recommend
that all women especially with the family history of early menopause
should have a baby at an earlier age. All the infertility treatments
and even IVF cannot be successful if women’s ovarian function is
diminished.
HOW
DO WE APROACH THE INFERTILE COUPLE ?
We first evaluate the male partner. Two or three sperm counts one
month apart are ordered and evaluated.
WHO (World Health Organization) and Krugers` criteria is used to
analyze the sperm parameters.
If the sperm count is
abnormal, hormonal tests and ultrasound of the testes is performed.
This way, hormonal and vascular problems may be detected.
In male infertility however, medical and surgical therapies are
getting less and less popular due to high failure rates.
Therefore for male
infertility, currently artificial insemination or IVF/ICSI is
recommended, depending on sperm count results.
For WOMEN,
We
order FSH, LH, E2, PRL, and TSH hormon levels on the third day of the
period. If these are normal, ovulations are monitored with ultrasound.
If there is an ovulation problem it is treated by oral medications or
hormonal injections, monitored by ultrasound.If the ovulation is
normal, then Hysterosalpingography ( X-ray of the uterus and tubes) is
performed to rule out the tubal blockage.
If there is a problem
with the tubes, laparoscopic correction is tried in certain cases.
However, in recent years due to highly successful IVF/ICSI results,
tubal surgery is performed less often.
In some couples no
cause is found. This is called as unexplained infertility. In this
group, firstly 3 to 6 months of ovulation induction treatment is
given. If this is unsuccessful, artificial insemination is used for 3
to 6 months as well.
If all these fail,
then IVF/ICSI should be performed
In general, below age 40 with normal hormones of the female, classical
treatments are successful in almost 70 percent of the cases. IVF/ICSI
would be the answer if the classical treatments are unsuccessful, the
sperm count is very low, and both tubes are blocked.
The age of woman is a
serious factor. If the age is over 40, the chance of getting pregnant
is lessened, so the classical non-IVF treatments should be given for a
short time only. Therefore IVF/ICSI is used earlier and more often.
IVF/ICSI
In 1978, the first test tube baby Louisa Brown is born
in London. This revolutionized the infertility technology. Millions of
IVF babies have been born and procedure is getting more and more
popular.
In
normal conditions, women produce an egg and this egg is captured by
the Fallopian Tube. Egg travels in the tube and meets the sperm.
Fertilization occurs in the tube and 2-3 days later, the fertilized
egg (zygote) enters the uterine (womb) cavity. Under natural
circumstances, this zygote implants in the endometrium (lining of the
womb) and the chance of pregnancy is 20% only. For some reason, these
events cannot occur in infertile couples.
IVF/ICSI
procedure mimics these natural events. Women receive hormonal
injections to increase their number of available eggs. The eggs are
monitored closely by ultrasound. When they reach to 18-20 mm in size,
they are triggered by HCG injection to complete maturity which happens
after 36 hours. At this time patients are taken to the operation room
and under sedation anesthesia eggs are retrieved by ultrasound guided
follicle puncture.
Meanwhile, male
partner gives sperm. Sperm is evaluated and most mobile and normal
part is taken to be used for the IVF/ICSI procedure.
In
normal IVF procedure, eggs are placed in a Petri dish and inoculated
with 100.000 sperm per egg. Mixture is placed in incubators and
following day eggs are checked for fertilization. In normal
circumstances with a good sperm count approximately 70/80 percent of
the eggs are fertilized. The eggs continue to divide and two days
after the egg recovery they achieve 4 cell stage. On the third day,
embryos reach 8 cell stage. Same day, healthiest three embryos are
taken and placed in the women’s uterus by plastic catheter. In our
center all the embryo transfers are performed under careful ultrasound
guidance in which uterus is seen easily, and embryos are transferred
exactly 2cm below the top of the cavity. This gives the best pregnancy
chance. Pregnancy test is performed 12 days later.
ICSI
PROCEDURE
In IVF procedure sperm and egg are placed in the same
dish and fertilization of the eggs by the sperm is expected. However,
if the sperm count is extremely low or the sperm is mostly abnormal,
fertilization cannot occur. Even with the normal sperm sometimes
fertilization cannot happen for some unknown reason. In ICSI procedure
single sperm is taken and injected into the egg by means of micro
needles which guarantees the fertilization.
ICSI procedures are
getting more and more popular, because it does not take a chance of
“sperm not fertilizing the egg”. In our clinic, ICSI is used
routinely and therefore the pregnancy rates are increased. Unlike
other clinics in the western world, there is no surcharge for ICSI in
Jinemed Hospital, Istanbul.
Sometimes no sperm is
found due to congenital absence of connecting tubes between the testes
and the penis. In this situation, sperm can be found by testicular
biopsy. This is called TESE procedure. Sperm achieved this way can
also be used for ICSI.
Increasing
the pregnancy rates
In order to increase the success rates, certain
procedures are performed as necessary. For example, some embryos have
a thick outer layer which prevents the embryos to attach the lining of
the womb. To solve this problem, the laser is used to thin out the
outer layer. This is called the Assisted Hatching. Also in some cases,
the embryos are transferred not 3 but 5 days after the egg recovery to
select best embryos. 5th day embryo is called blastocyst and this
procedure is called blastocyst transfer.
In multiple IVF/ICSI
failures, one reason maybe chromosomally abnormal embryos. For this
reason PGD (preimplantation genetic diagnosis) is performed. With this
technique one cell from the 4 cell embryo is taken carefully and
examined for chromosome analysis. Embryos, which have normal
chromosomes are then selected, and transferred to the woman’s uterus
the following day.
In some IVF/ICSI
cycles several embryos are produced and three of them are given,
remaining good quality embryos are frozen for the future use. Embryo
freezing is a well developed technique today that allows women to have
another chance of pregnancy. Embryo transfer is much cheaper than
regular cycle because no medication is used and no anesthesia is
required. Embryos are frozen for several years and can also be used in
the future if the couple desires another child or if the first cycle
is unsuccessful.
Ovarian
Cortex Freezing
For young women with certain types of
cancer (breast, lymphomas, etc.), chemotherapy is required which is
detrimental for ovarian functions. If these women desire future
pregnancy part of the ovaries should be removed and frozen. This is
done laparoscopically. Outer layer of the ovary contains numerous eggs
which can be frozen and used for ICSI procedures in the future. This
new technique seems very promising and available at Jinemed along with
very few clinics in the world. Approximate medical cost is $10.000
Sperm
and Egg Donation
Egg and sperm donation is not legal in Turkey.
Therefore we cannot do these programs in Istanbul, however we have
associated clinics in northern Cyprus and Greece. We can prepare the
patients for this procedure. Under our guidance and supervision, we
will send you to these clinics. Average medical cost is 6000 euro for
egg donation and 4000 euro for sperm donation.
We wish you great
success in your treatments and we are happy to welcome you to our
beautiful city of Istanbul with its famous Bosphorus and historical
places such as Topkapi Palace, and Hagia Sophia. You will also enjoy
the famous Turkish cuisine with Doner Kebabs, Shish Kebabs, and
delicious fish. It will not only be a medical visit but culinary
experience as well.
