Assisted Reproduction

  • Intrauterine Insemination: Insemination may be the first step for infertility treatment. The method is simple and affordable. The success rate in homologous insemination reaches 10-15%, while in cases of heterologous insemination, the rate is higher (~25%).
  • Assisted Reproduction (IVF-ICSI-FNA-TESE): In vitro fertilization (IVF) is currently the definite choice of infertility  treatment when other,  simpler methods of assisted reproduction are not able to  provide solutions (i.e. women with closed or destroyed fallopian tubes). ICSI (Intra-Cytoplasmic Sperm Injection) is a type of IVF with micro-fertilization. It is indicated in cases of male infertility and may be  combined with  TESE or FNA (Testicular Sperm Extraction - Fine Needle Aspiration).
  • Male Infertility Treatment: Andrology unit of IAKENTRO offers both diagnosis and treatment in male infertility.
    Male infertility covers a wide range from  complete absence of germ cells till mild  forms of astheno-oligo-teratospermia.
  • Oocyte Donation: The oocyte donation program of IAKENTRO was established in 1989, when we achieved the first pregnancy from oocyte donation in Greece, which resulted in the birth of full-term twins. This success has been the trigger for the initiation of a special oocyte donation program, with the participation of volunteer donors.
  • Sperm Donation: Sperm donation is the only solution in cases when  methods  for the treatment of male infertility (IUI, ICSI, FNA, TESE) cannot be applied.
    Sperm donors, 18-35 years of age, are examined by an Internal Medicine Physician and are subject to a number of laboratory tests.

  • Embryo Donation: This is indicated for couples where both partners (man and woman) are not able to undergo infertility treatments with their own gametes (oocytes and sperm).
  • Gestational Surrogacy
  • Sperm Diagram | Sperm Enrichment: This test checks the quality of semen, identifying sperm concentration, motility and morphology.
  • Sperm DNA Analysis (DNA Fragmentation): Recent studies have shown that sperm DNA fragmentation, which is an indication of increased sperm apoptosis percentage, might be the cause for IVF failures. These studies have demonstrated  that, in semen samples in which the percentage of sperm with DNA damage is higher than 20%, the chances to achieving  pregnancy are significantly reduced.
  • In Vitro Maturation Of Oocytes (IVM): In  cases of IVM, ovaries are only mildly stimulated. Oocytes are then collected, however, final stage of maturation takes place at the laboratory. Finally, fertilization and embryo transfer  follows, like in an  IVF cycle. IVM is a method which may provide solutions in certain cases where  administration of hormones to stimulate the ovaries is difficult or contraindicated.
  • Biochemical Assessment: This is a new technique  assessing  the ability of embryos resulting from IVF  to implant  in the endometrium.
    Results of recent studies have shown that embryos demonstrating sHLA-g protein above certain levels,  have higher implantation rates.
  • Assisted Hatching: At the early stages of development, embryos are covered by an outer layer, the transparent zone, which protects embryonic cells. This zone is partially diluted and the embryo “hatches” when it reaches the uterus, so that it can be implanted in the endometrium and keep developing. However, in certain cases of IVF, it is considered necessary to assist hatching by reducing the transparent zone width. The procedure is performed on the day of embryo transfer using a special laser.

  • Preimplantation Genetic Diagnosis: In this  procedure, the  genetic material of embryos is checked prior to embryo transfer. This method constitutes a combination of in vitro fertilization and special genetic analysis  techniques.
  • Blastocyst Embryo Transfer: Culture media are continuously improved   to adapt  in  the best way to the embryo’s needs in different stages of development and culture conditions in incubators are continuously  optimized Thus, recent advances  have allowed us embryo   culture until the blastocyst stage.
  • Oocyte Cryopreservation: Oocyte vitrification was first announced in 1987; however, until recently it was an experimental procedure, since gestation rates were disappointing due to the low survival rates of embryos. Recently, an improved vitrification method has been  developed, based on faster vitrification, which ensures a higher oocyte survival rate (up to 100%) and a pregnancy rate of 40%.
    Vitrification of unfertilized oocytes will bring revolution in the treatment of assisted  reproduction as women will be able to keep their oocytes vitrified for a long period of time.
  • Embryo Cryopreservation - Vitrification: This method is used in the following cases:
    When embryo transfer cannot be performed for some reason (e.g. hyperstimulation of the ovaries);
    When there are excess embryos with normal development and morphology after the transfer and can be  used in a subsequent  cycle.
  • Ovarian Tissue Cryopreservation: Ovarian tissue cryopreservation is, currently at experimental stage. It may be applied in women who will undergo chemotherapy or surgical removal of ovaries. During this procedure, solid parts of the ovary containing several immature follicles are removed by laparoscopy and are frozen.

  • Sperm Cyropreservation | Sperm Bank: Sperm cryopreservation is a widespread method, frequently applied with great success as  survival rates of spermatozoa after thawing are very high.
  • Psychological Support: In vitro fertilization has set new grounds in the treatment of infertility, currently demonstrating high success rates. Nevertheless, it remains a difficult procedure causing psychological stress. Each person reacts differently to infertility. It is normal that any of the partners  attempting IVF may  fear the unknown medical action and feel insecure about the impending procedure.  Very often, couples wish to share those feelings with a specialist who will support them, in strict confidence.

Preserving Female Fertility – Freezing the Biological Clock

The latest developments in the field of reproductive medicine guarantee the preservation of fertility for women who wish or need to do so. This involves the new revolutionary method of oocyte vitrification combined with rapid thawing. According to professor Nikos Prapas, who applies this new method at the IAKENTRO medical centre, the rate of viability is as high as 90%.

According to theprocedure followed, the oocytes are retrieved either following hormonal stimulation of the ovaries (freezing of multiple oocytes) or during the natural menstrual cycle (freezing of the oocyte that is naturally produced every month). When the woman wishes to become a mother, the oocytes will be thawed and the standard procedure of in-vitro fertilization will be followed (fertilisation and embryo transfer).

This method is applied to women of a young age, when their oocytes are still “young”, who wish to start a family at a later age due to their careers or other circumstances, in which case it is deemed necessary to preserve their fertility. In fact, the ageing of the ovaries begins gradually at the age of 34-37, and becomes more drastic from the age of 38 onwards. There are also other iatrogenic conditions that speed up the ageing of the ovaries, such as ovarian cancer, chemotherapy or radiation, and early menopause.

“By applying this method we are essentially freezing time and giving all women the opportunity to feel complete through child-bearing, even if their biological clock has already stopped ticking”, states Mr. Nikos Prapas.

Sub-fertility among ultra-thin women

According to recent studies, ultra-thin women face minor or major sub-fertility problems. This differs from the view widely accepted to date, i.e. that overweight women were those less likely to achieve pregnancy, either naturally or by in vitro fertilisation.  

The index indicating whether a woman is ultra-thin, of normal weight or obese is called Body/Mass Index (BMI) and it is calculated by dividing a person’s weight in kilos by the square of their height in metres (weight/height2). Women with a BMI of 14-18 are considered ultra-thin, with a BMI of 19-28 normal and with a BMI of 29-43 obese. Initially it was assumed that women with a low body weight were less likely to conceive due to low oestrogen production. This might have a negative impact on ovulation or even interrupt it, while also affecting endometrial thickness, and, consequently, the capacity for embryo implantation. However, it has been observed that body weight plays a role even in cases of women on hormonal treatment in preparation for in vitro fertilisation, which leads to the conclusion that the weight – sub-fertility correlation is not a matter of hormones.   

According to Professor Nikos Prapas (Obstetrician – Gynaecologist), “the most recent current view is that pregnancy may not be achieved due to embryo undernourishment, leading to implantation failure”. This is what Mr. Prapas concludes: “When a woman wishes to get pregnant, either naturally or following some form of sub-fertility treatment, she needs to look after her weight and maintain it within normal range, rather than trying to comply with social norms”.
