Welcome to Dr Panagiotis Karantzis ΜD, PhD, DRCOG - Obstetrician - Gynecologist official webpage

Through these lines I would like to welcome you in this website.

I believe that that here you will find the answers to your questions. Questions like what subfertility is, and what it is all about assisted reproduction.

With simple words I am sure you will be able to clarify meanings and definitions that many times cause confusion and more often misunderstandings.

I believe a well informed couple has always a better chance of communicating better with his doctor.

This will cause less anxiety and stress to the couple and eventually this will make the patients calm and happy. This is my responsibility.

This is were you can find this website helpful. I hope you will enjoy it.

The standard way of oocyte fertilization with processed sperm in special culture medium and incubation in a special chamber.

ICSI (Microfertilization)

Fertilization of eggs with implantation of a morphologically good spermatozoon using a micropipette in the cytoplasm of every oocyte. This method has solved to a great extent the problem of male factor infertility.


Testis biopsy for the detection of spermatozoon in men with azoospermia, in other words, without the presence of any spermatozoons in the sperm.


Improves a relative ‘moderate’ sperm regarding its number and motility. To do an IUI it is mandatory to know that patient’s tubes are patent. It is for patient’s best interest not to do more than 3 IUI attempts. If all three fail it’s prudent to proceed to an IVF cycle.


Epididymis biopsy in order to find spermatozoons. It is recommended to men with azoospermia and atrophic testes.

Assisted Reproduction - IVF FAQ

Of course you can, we stress out to all women who are about to commence with the programme that they are not incapacitated and they do not have to discontinue their everyday activities and habits.

Oocyte retrieval is conducted transvaginally under ultrasound guidance and with mild anesthesia (sedation). Therefore, the patient awakens rapidly and may go home with the appropriate instructions.

As already mentioned, during ovarian stimulation monitoring nothing changes significantly in the woman’s everyday activities. Moreover, the woman can return to work the very next day following oocyte retrieval. However, after embryo transfer and for at least 3-4 days, she must remain at home. The patient must avoid lifting weight, sexual intercourse, exercise, using stairs and must be careful with constipation.

The woman who underwent embryo transfer is not ill. She can use the toilet, take her bath and eat with her spouse.

You do not discontinue the medication you are taking and you have to check serum estradiol levels and progesterone the next day. From there on, according to test results, the dosage of drugs is increased or decreased so as to maintain them within therapeutic levels.

When the serum levels of b-HCG exceed 1200 IU/l, which occurs 2-2 1/2 weeks later.

Levels of b-HCG should be overdoubled every 2 to 3 days.

Injections are now administered subcutaneously. In other words, we use a small-gauge needle used for diabetic patients and after a demonstration and training by the IVF Unit’s personnel, women can self-inject, without the need for a third person with experience in intramuscular injections.
