Chances and Risks of the Treatment

Prospects of success and possible risks of infertility treatment

Here, we would like to mention that the probability of origination of natural conception at a healthy and fertile couple is approximately 15 – 20 % per cycle.


The reason is the fact that ovulation may not occur or ovulation occurs, but the ovum may not be quite mature and thus infertilizable. We further know that many pregnancies finish prematurely with menstrual flow - the so-called preclinic miscarriage. We have to find the explanation in complicated mechanisms connected with origin of a new life in the mother's body. Sometimes also failure of the first division of the fertilized ovum occurs or the embryo fails to nest in the uterus for various reasons.


For these reasons it is usually recommended, particularly at heavy fertility disorders and higher age of the woman, to carry two (however not more than tree) embryos. Therefore the hormone stimulation of ovaries is necessary so that we have more embryos for the selection. All of these increases the chance for occurrence of pregnancy.


However, the hormone stimulation may lead to undesirable hyperstimulation of ovaries. This situation is called the ovarian hyperstimulation syndrome (OHSS). A large quantity of liquid gathers in the body cavity, which leads to strong pains in lower abdomen and a feeling of inability to take a breath. Therefore it is necessary to keep in touch with our workplace during the entire treatment. To manage the hyperstimulation syndrome it is necessary to stay in a hospital for a short period in exceptional cases. If regular examinations are carried out during the treatment, it is possible to reduce the percentage of hyperstimulation cases to 1 – 2 %. Therefore we rely on out mutual informing, so that we can prevent this situation already at first symptoms.


It is good to know that:


Based on current studies the hormones used do not increase the risk of occurrence of tumorous conditions.


Considering the fact that 1 to 3 embryos may be implemented at in vitro fertilisation, the risk of multiple pregnancies rises. At approximately 5 – 15 % cases the bigeminal pregnancy and at 1 - 2 % the trigeminal pregnancy occurs. If a spontaneous failure of one of the embryos does not occur until the 9th week, we recommend carrying out selective reduction from 3 to 2 embryos during the 10th - 11th week of pregnancy.


Extra uterine pregnancies are more frequent in case of infertile women after natural conception and in IVF program as well. The reason is that embryos may move to a damaged fallopian tube after the transfer. Therefore it is important to examine the gestational sac after 2 weeks after a positive pregnancy test, ascertain this danger, and treat it in time.


Approximately 10 % of all pregnancies end with a miscarriage. After IVF, this risk is a little bit higher - approximately 10 – 15 %. This is probably caused by higher average age of the treated women in comparison with the group of women with spontaneous pregnancy. The reason is that the risk of miscarriage rises with the age due to genetic changes of the ovum.


Is there any Risk for the Child?


Here we have to note that the risk of developmental defects for pregnancies originated in a standard manner ranges between 2 and 4 % . This rate of risk is not increased or decreased for IVF.


Existing results of research of pregnancy after IVF prove that even after ICSI the risk rate of developmental defects is not increased. It was recently ascertained that hereditary factors caused heavy fertility disorder at approximately 3 – 5 % of men with such problem. If those men have a male descendent thanks to the ICSI method, the descendent may also suffer fertility disorder, but in other aspects he will be probably healthy. Further, it is known that approximately 1 – 2 % of infertile men are carriers of a hereditary disorder of metabolism - cystic fibrosis /CFTR/. Only an examination of their female partners for cystic fibrosis may almost completely exclude origin of this serious disorder at children. For these reasons we recommend these couples to carry out a detailed genetic examination and a preconceptual counselling. All the female and male donors are excluded from the donation program if the cystic fibrosis has been ascertained. Generally, we can say that no genetic cause of infertility is ascertained at the majority of infertile couples who undergo IVF / ICSI. However, larger occurrence of this disease may appear in cases of repeated failure of implantation or repeated miscarriage.


Prospects of Successful Treatment of Infertility


The success rate in achievement of pregnancy of a concrete couple after a simple hormone stimulation connected with insemination ranges between 10 and 18 % for a cycle. If more such cycles are carried out, it is possible to achieve the longed-for pregnancy at approximately 70 % couples. However, we have to add that this procedure may be selected only for light fertility disturbances with a real chance for success.


After in vitro fertilization the rate of success of treatment ranges between 25 and 45 %. The chance for origination of pregnancy after ICSI is a little bit higher, and for this there are two possible explanations: firstly - the women of men with fertility disorder are younger than the women undergoing IVF, and secondly, ICSI provides higher chances for fertilization of an ovum. The probability of pregnancy rises also with the number of past cycles - currently, we can say, that during three IVF treatment cycles we can help to approximately 60 – 70 % couples to have their children. This is the so-called cumulative successfulness of treatment applying IVF methods.
