In our clinic we offer fertility treatment for women with poor egg quality, as there is always a reason for this. With conditions such as PCOS (Polycystic Ovarian Syndrome), Endometriosis, etc., this is treatable in most cases, but there are other circumstances such as age which require a different strategy. Ageing of the eggs is a determining factor for egg quality, making fertilisation more difficult or provoking repeated miscarriages. In these cases we focus our efforts on defining and selecting the best cycles for egg extraction. It is also essential to have a stimulation strategy that will help us to obtain the best egg.
