Infertility: a common issue
10-15% of all couples are affected by infertility, defined as failure to conceive after at least a year of trying. Following examination and treatment, however, around two-thirds of these couples go on to have children.
Causes of infertility in men:
Causes of infertility in women:
Causes of infertility in both men and women:
Polycystic ovary syndrome (PCOS)
The most common cause of ovulation problems is polycystic ovary syndrome (PCOS), which affects 5-10% of all women of childbearing age. PCOS has hereditary origins and can lead to increased production of the male sex hormone testosterone and problems with insulin and blood sugar balance.
The disease results in numerous small cysts - immature follicles - in the ovaries, failure to ovulate and irregular periods. PCOS is treated through diet, exercise, weight loss and contraceptive pills. If a woman with PCOS wishes to conceive, medication and follicle-stimulating hormone can be used to stimulate the maturation of follicles in the ovaries and induce ovulation.
Endometriosis - a cause of pain and fertility problems
Another common cause of infertility is the chronic disorder endometriosis, where the lining of the womb grows outside the womb itself, generally in the abdominal cavity. It often leads to blockages in the Fallopian tubes and can affect egg quality. It can also cause severe pain during menstruation and intercourse. 10% of all women suffer from endometriosis to some degree.
In vitro fertilization (IVF)
Hormones are given to the woman to make more eggs mature from one of the ovaries.
Mature eggs from the woman's ovaries used to be extracted using keyhole surgery. Today, ovarian follicles are located using ultrasound and the eggs are extracted with a thin needle.
Sperm are added to the egg so that fertilization can take place. The fertilized egg begins to divide and develops into an embryo.
The young embryo is returned to the womb where it attaches to the lining.

What is Infertility?
Infertility is the failure of a couple to conceive a pregnancy after trying to do so for at least one full year without using any method of birth control. This health issue may originate with problems originating in either or both members of the couple. About 30% of the time, the root of the couple's infertility is due to a problem with the male partner; about 30% of the time, it is due to the female partner; and about 40% of the time, there are fertility problems with both the man and the woman, or else the root cause is undetermined.
What factors cause infertility?
The main factors are infection by sexually transmitted diseases, a history of infection of the female reproductive organs, a history of testicular or sperm duct infection, a history of mumps in men, irregular or no menstruation, endometriosis (a condition in which bits of the tissue from the lining of the uterus flourish outside the uterus), congenital anomalies of the uterus, chronic diseases, advanced age, smoking, alcohol and drug addiction.
IUI (Intrauterine Insemination)
Sperm obtained through masturbation is processed in the laboratory, with the best examples being extracted and concentrated. The prospective mother whose eggs have been matured with hormone medication undergoes a painless 15-minute procedure in which motile sperms are inserted into her uterus for spontaneous fertilization. Vaccination treatment can be performed up to 4 times as long as there is nosevere disorder in the sperm, the woman’s tubes are open and there is no concern in terms of problems with the eggs or age. On average, each procedure carries a 20% chance of success.
‘Test Tube Babies’ (IVF)
Technically called in-vitro fertilization (IVF), the “test tube baby” method is a procedure in which eggs collected from the prospective mother’s ovaries are combined with the prospective father’s sperm in the laboratory, and the embryos that are obtained are re-implanted in the mother’s uterus. In the first stage of the treatment the eggs are formed and are then collected at the appropriate time. Fertilization occurs when they are combined with the sperm in the laboratory, and the embryos that develop are re-implanted in the mother’s womb. Traditional IVF methods were first carried out in 1978 and soon began to spread worldwide. Our Center has been carrying out successful IVF procedures since 1998, using the microinjection “ICSI” (Intracytoplasmic Sperm Injection) technique invented in 1992.
Traditional IVF (In Vitro Fertilization – Test Tube Baby)
About 500,000 sperms are combinedwith every 7 or 8 eggs, and spontaneous fertilization is then awaited. IVF is generally the preferred method for women who are unable to conceive because of blocked or restricted fallopian tubes,for male-factor infertility, and forwomen who do not have egg-related problems.
A single sperm is selected under the microscope and injected into each egg with a thin needle. Subsequent stages in the procedure follow the same path as the traditional test tube baby method. This method reduces the risk of non-fertilization. First introduced in 1992, ICSI represents a revolutionary development for couples who are unable to have a child, especially for male-factor reasons. Microinjection is the method of choice for minimizing failure to fertilize not only for male-factor infertility cases, but also when thickening or hardening of the outer egg membrane prevents entry of the sperm, for couples who have previously tried IVF without success, and in particular for older couples and women who produce few eggs.
ICSI (Intracytoplasmic Sperm Injection – Microinjection Method)
Who are suitable candidates for IVF?
Both fallopian tubes are severely blocked. In this case, the sperm cannot reach the egg for fertilization; even in less severe casesin which fertilization may occur rarely, there is an increased rate of ectopic pregnancy.There is severe disorder in sperm count, motility or appearance. These sperm-related problems may occur in conjunction or on their own, and the success rate for couples only facingsperm-related problems is generally higher. Couples who have undergone intrauterine treatment without success. IVF is not recommended for couples who have still failed to conceive after 4 attempts. Endometriosis. This is a condition in which cells from the lining of the uterus (the endometrium) that assure a regular monthly menstrual cycle flourish outside the uterus, in the tubes, ovariesand abdomen. Bleeding occurs in these regions during menstruation; adhesions develop in the abdomen and cysts in the ovaries and IVF treatment may be necessary. Age factor. We know that egg reserves diminish markedly in women over the age of 35. In these cases, IVF is recommended without undue delay.
IVF Treatment Step-by-Step
Various medications are used in order to stimulate egg development in the ovaries. Under normal conditions, one egg grows every month but in IVF treatment we know that the probability of success is increased when between 10 and 20 eggs are developed. For that reason the ovaries are stimulated with the controlled administration of medication. The eggs develop within small aggregations of cells called follicles. The eggs inside the follicles are not visible and follicle growth can only be followed using ultrasonography. Under ultrasonography, the eggs are collected in the 36th hour after the injection of hCG (a hormone used to induce ovulation). Eggs are collected in operating theater conditions via the vagina, under general anesthetic and with the aid of ultrasonography. Sperm is obtained from the male in a specially prepared room by means of masturbation and the highest quality sperms are selected in the laboratory. Subsequent procedures differ according to whether the couple is undergoing test tube baby or microinjection treatment.
The outer membrane of the egg (zona pellucida) is opened under the microscope by laser or mechanically, facilitating the emergence of the embryo before it is implanted in the uterine wall.
Defragmentation (removal of cell debris)
From time to time the embryos expel debris as they divide; these structures diminish embryo quality and can hinder the progress of division. This debris is removed by means of the insertion of a thin pipette.
If pre-implantation genetic diagnosis is to be carried out, one or two of the cells that comprise the embryo are removed for genetic examination. This aims to achieve selection of the healthiest embryos.
PGD (Pre-implantation Genetic Diagnosis)
In IVF procedures, embryos are selected between the 2nd and 6th days and transferred to the prospective mother. In spite of the selection of the embryos with the best appearance, the success rate for implantation into the uterine wall and clinical pregnancy is not 100%. In the first 3 months after pregnancy has occurred, miscarriages due to genetic disorders may take place. PGD techniques developed in recent years allow detection ofthis group of embryonic genetic disorders. The introduction of PGD in IVF applications has revealed some of the causes of low pregnancy rates. This method has shown that depending on age, an average of 30% of even the embryos with the best appearance (and 90% of those considered poor quality) are genetically impaired. For that reason, the probability of pregnancy resulting from embryos that appear healthy but have genetic abnormalities is very low, and even if pregnancy occurs there is a high probability of miscarriage.
Who has a higher incidence of embryonic genetic disorder?
If at least 2 healthy embryos are formed apart from the embryos that are transferred after treatment, they can be frozen and stored for up to 5 years. These embryos are stored in liquid nitrogen in very specific conditions at - 196° C and can be implanted in the patient’s uterus when desired. This process is designed to achieve pregnancy using the frozen embryos without having to repeat the egg development, collection and laboratory work that has already been carried out.
Implanting embryos in the uterus (Embryo Transfer)
2 to 6 days after the collection of eggs and fertilization, one or two of the embryos that have formed are implanted in the mother’s uterus by means of a special catheter in a highly sterile and sensitive manner. The procedure is painless and considerably easier than a normal gynecological examination. This takes about 15 minutes. The patient is then given detailed information about the number and quality of the implanted embryos, the risks of multiple pregnancy and the precautions that can be taken. The patient can return home after resting for half an hour or so. She may return to work the next day as long as it does not involve intense stress and physical activity. Sexual intercourse is not advisable during this period.
