Malaga, Espana (PressExposure) July 12, 2011 -- Clinica Fertia Spain understands that the fertility journey is very daunting for couples and single women; and a lack of knowledge contributes to fears and uncertainties. To help those considering or going for treatment, this interview with Dr. Elena Puente explains clearly the various stages of IVF-In Vitro Fertilisation in Spain, at Clinica Fertia.
Q: Dr. Puente, what would you say to couples and women who are considering IVF-in vitro fertilisation?
A: "The process of IVF-in vitro fertilisation is not such a complicated procedure, and includes three different stages. Stage one is stimulation, which at our clinic is light stimulation, then the second stage is collection, which is done under sedation and finally embryo transfer which is painless."
Q: What do you mean by light stimulation?
A: "Light stimulation refers to the fact that nowadays, most centres promote friendly stimulation in order to get an accurate number of eggs so that patients are not uncomfortable, and there are enough eggs to succeed.
Overuse of drugs is not good. A larger quantity of eggs does not translate into the best chance of success; more is not better. This was the old-fashioned approach, but is not popular anymore.
With our approach, women will experience symptoms like premenstrual symptoms, so they can go about their normal daily activity."
Q: How many eggs are recommended for the best chance of success?
A: "Too many eggs can mean too many abnormal eggs- eggs which have chromosomal abnormalities.
Best practices are stimulation resulting in between 8 to 15 eggs in one or two cycles, so you can get best option for pregnancy. If we analyse the number of embryos you will need to transfer in order to have a baby, these are the average statistics.
5 embryos will give an average chance of 52%, 10 embryos 69% and 15 embryos 79%. Over this number a plateau is reached, so you do not get a better result, with a larger number of embryos.
Our clinic performs friendly stimulation protocol. Our aim is to get around ten eggs, so we make sure, that the stimulation is cost effective, less complex, less time consuming and best for patients so they do not get so many side effects and complications."
Q: How does the egg collection stage work?
A: "We make the patient feel comfortable, as we do it under sedation, so she feels nothing during this procedure.
This procedure does have risks, but nowadays we have very accurate ultrasound machines, doctors are very familiar with this technique, and the incidence of major complications is very low."
Q: Explain how the embryo transfer works?
A: "It is an easy procedure; the patient feels nothing while we perform embryo transfer. Most centres nowadays perform this procedure under ultrasound guidance, and in our centre we also perform this guided transfer before the actual cycle. We call it test embryo transfer, so we get familiar with this particular case, and make sure the procedure is easy, feasible and comfortable for patient.
Our centre performs double or single embryo transfer. Our law for reproduction allows us to transfer three embryos maximum, but we never transfer three.
Nowadays, we perform more and more single embryo transfers, we get as good result, when we transfer one embryo on blastocyst stage, as when we transfer two embryos on day three, this is best way to reduce multiple pregnancy which is risky for mothers and children."
Q: What type of risks do multiple pregnancies hold?
A: "Some of the main risks related to multiple pregnancies are early birth, premature rupture of membranes, diabetes and preeclampsia."
Q: Have you any advice or guidance to offer those considering IVF-in vitro fertilisation?
A: "The main thing is to realise that the whole process is easier than you think. If it wasn't so easy, for example donors, will never accept to donate their eggs more than once, and in our clinic, for example, 99% of donors want to do it again.
We are a conservative clinic and would recommend that those seeking IVF bear this in mind when choosing a clinic. What I mean by conservative, in the case of IVF treatment, is that we do not perform too much stimulation. It is not going to improve results and we are very concerned about multiple pregnancies."
