May occur change in menstrual flow after the ligation. The frequency of menstrual changes ranges from 2.5 to 60%. A study conducted by the University of Botucatu with more than three hundred women found a percentage lower than 10% of menstrual changes.
At causes of menstrual changes are not entirely known. There are a few attempts to explain them, such as failure or interruption of ovary blood supply, modification of the nerve impulses of the fallopian tube and / or ovary, torsion of the ovary, and pelvic adhesions. Another possible explanation is an insufficiency in the luteal phase caused by suppression of irrigation between the uterus and ovary.
Also, stopping using the IUD (intrauterine device) or pill can also cause menstrual changes. The IUD predisposes to increase the amount and duration of the menstrual flow. When the user stops using it, these signs tend to decrease. The menstrual cycle is normalized and the amount of flow decreases when hormonal contraceptives are used. So when they stop using this method, irregular menstrual cycles often return.
It is important to take into account the menstrual patterns prior to sterilization. If the menstrual cycles were irregular, they will probably be irregular again.
In the presence of irregular menstrual cycles, hormonal pill may be prescribed, in an attempt to regularize the flow. The gynecologist should be consulted.
