Ovarian stimulation aims to achieve the growth of multiple eggs. This will mean that the ovaries will reach a much larger size than usual. This increase in size will be maintained from almost the beginning of the ovarian stimulation until several days after the puncture and ICSI.
The fact that the ovary is larger than usual is a risk factor for possible ovarian torsion. This consists of a complete or partial rotation of the ovary on its supporting elements, with the consequent loss of its blood supply, which is a medical emergency requiring early surgical intervention to avoid necrosis and loss of the ovary.
For this reason, it is advisable to rest after the puncture, avoiding above all exercise with impact and sexual relations until some time has passed and the ovaries have returned to their normal size. In addition, on the day of the puncture, this rest should be carried out more strictly due to the side effects that the anesthesia used for the intervention may have.
