Accumulation of oocytes in patients with a low response.

The number of oocytes retrieved is a key prognostic factor in In Vitro Fertilisation (IVF) treatments. Chances are greater the greater the number of retrieved oocytes is, until the moment when 6 to 8 oocytes have already been retrieved.
For this reason, care of patients with a Low Response should be especially thorough, both as regards the chosen protocol for ovarian stimulation and the processes of oocyte retrieval and management at the laboratory. In these cases, retrieving an extra oocyte may considerably increase the chances of success.
While many of these patients benefit from the implementation of specific stimulation protocols and the use of adjuvant therapies, some of them will be refractive and will yield a very poor response.
The appearance of vitrification as a successful technique to freeze both oocytes and embryos has stirred new expectations in patients with a low response at the possibility of accumulating vitrified oocytes from several stimulation cycles. This way, after performing a number of oocyte collection cycles and once collecting a number between 6 and 8 oocytes has been achieved, the processes of fertilisation begin. In this case, prognosis is more favourable, as patients now have more or less the same number of oocytes as those patients with a normal response. […]

Differences between Artificial Insemination and In Vitro Fertilisation

Artificial insemination is a simple technique carried out on couples with specific fertility problems.

The ideal candidate would be a young woman with permeable fallopian tubes, less than 3 years of sterility and a male partner with normal semen. Artificial insemination is useful for couples that meet these requirements. No more than 4 tries are carried out, and the overall pregnancy rates are 25% – 30 %.
