Interview with Staff of Women’s Health Dexeus in Barcelona
Dr Nikolaos P. Polyzos is a new doctor and the Clinical and Scientific Director of the Service of Reproductive Medicine at Women’s Health Dexeus in Barcelona, Spain. He attended the 43th Dexeus International Forum, a meeting organised by Dexeus Institute on October 26-28th 2016 with more than 850 attendants from 41 different countries. The Dexeus Forum, that was held in Barcelona, updated the current knowledge in Obstetrics, Gynaecology and Reproductive Medicine. In this Forum Dr. P. Polyzos described how ovarian stimulation treatments have improved in last years and offer solutions for poor responder women.
How did ovarian stimulation treatments improve since its conception?
All over the last 20 years we have seen a lot of improvement in terms of medication that has been used in reproductive medicine for ovarian stimulation. This has changed and has improved the outcome in the patients, but I think that one of the key points that has changed has been the segmentation of IVF treatment. We stimulate the patients and we don’t do the fresh embryo transfer as it was done in the past, but we simply freeze the embryos due to the better cryopreservation techniques we have and we can transfer in the next cycle. This appears to be something really promising and we need future research to validate whether in the future this possibly can be applicable to all patients attending an IVF unit.
And what can be done in case of poor responders?
Poor responders is a very difficult group of patients which unfortunately we face quite often in our everyday practice. For example, in some centres the incidence is 25%, while in other centres it can be up to 30%. Patients come to your consultation and you need to provide a solution. Current treatments options do not really manage to increase a lot the chances of pregnancy in this population. Nevertheless, we are doing a lot of studies and actually one of the studies that has been now done in Institut Dexeus is the T-transport, in which we try to evaluate the effect of testosterone pretreatment in these patients. We hope this can give us another horizon for these patients and we can improve the chances of pregnancy in this very difficult population.
