IVF – Fertility

What is IVF?

IVF (in vitro fertilization) is a process by which an egg is fertilized by sperm outside the body in the lab. IVF is  an infertility treatment where all the other assistend reproduction methods like ovulation induction or IUI have failed.

Who is suitable for IVF?

  • Women with blocked tubes
  • Women with endometriosis
  • .Women who have tried  other methods of assistend  reproduction and failed
  • Women with ovarian failure
  • Couples with male factor infertility
  • Women with a history of repeated miscarriages
  • Surrogacy

What is the process?

  • First consultation

The first consultation is very important as a full medical history will be taken by both partners and the treatment will be explained in great detail. A transvaginal ultrasound will be performed to check the uterus, the endometrium and the ovaries (antral follicle count).

  • Hormonal treatment.

In IVF the woman receives hormonal therapy –gonadotrophins – in order to produce many eggs which are fertilized by partners sperm in the lab.

There are different IVF protocols  depending on woman’s age, hormone levels and previous response in IVF treatments.

  • Oocyte retrieval

The eggs are collected  transvaginally with fine needle  using ultrasound guidance under light sedation. The woman doesn’t feel any pain and she can return to her daily activities after 2 hours.

After the egg collection in classic IVF the eggs are mixed with the sperm in the laboratory under controlled conditions to promote fertilization. The next day we check how many embryos have resulted from the fertilization process and  day 2 or 3 or 5 (blastocyst stage) we transfer the embryos in the uterus.

If the quality of the sperm  is low  the method of choice  for fertilization is ICSI (intracytoplasmic  sperm injection). With this method we inject a single sperm inside the oocyte instead of using the whole sperm for fertilization.

12-14 days after embryo transfer the  woman  has  a pregnancy test (BHCG). We dont recommend a urine test. If the pregnancy test is positive an ultrasound should be performed 2 weeks later. The woman continues the medication she is given after the embryo transfer usually until the 12th week

IMSI (intracytoplasmic morphologically selected sperm injection) is a modified ICSI technique.

Fertility Preservation – Egg Freezing

Currently, many women postpone marriage and pregnancy until after 35 or even 40, due to professional commitments.

Mini Natural IVF

Mini IVF is a variation of IVF that requires little or no medication before oocyte retrieval.


As many as 65% of all embryos created do not survive the first months of pregnancy. Many of these embryos are unable to successfully implant.

Gestational Surrogacy

Surrogacy is a method of assisted reproduction where a woman gestates the child of another woman who is the biological mother.

Sperm Donation

Sperm donation is the provision of sperm for the purpose of of inseminating a female either through IUI or IVF
