We know that on many occasions the possibility of having a child after undergoing chemotherapy or radiotherapy they are reduced, and even disappear, due to the aggressiveness of the treatment. These therapies can damage a woman's ovaries, even irreversibly.
In accordance with conventional protocols, ovarian stimulation It only begins at the beginning of the woman's menstrual cycle, so that a patient diagnosed with cancer who should start her treatment immediately may not be in that situation and not be able to produce eggs that would be saved for a future conception.
However, a group of researchers has demonstrated a new technique: the ovaries can be stimulated so that they produce eggs for their extraction as well. during the final phase of the menstrual cycle.
Specialists have pointed out that depending on what phase of the menstrual cycle the woman is in when she is diagnosed with cancer, it may take 2 to 6 weeks to start ovarian stimulation and remove the oocytes, which for many women is a long time without starting cancer treatment.
The pilot study has been carried out on 40 women to see if it would be possible initiate ovarian stimulation during the luteal phase (after ovulation) to stop this phase and advance the production of a new egg.
The researchers point out that the number of oocytes obtained after stimulation during the luteal phase is small, but not significantly lower than those obtained after stimulation during the proliferative phase (before ovulation). The most important thing is that oocyte quality It is the same in both groups.
This investigation, which opens new hopes for cancer patients who want to be mothers Once the disease has been overcome, it has been announced at the XXIV Annual Meeting of the European Society of Embryology and Human Reproduction.
Another of the meetings that have taken place in this meeting is what we have seen on the biological clock of man, which also begins to mark after 35 years.
