Because many chemotherapy drugs have an inhibitory effect on the ovaries, many women experience irregular menstruation or even amenorrhea during chemotherapy, so chemotherapy definitely has an effect on women’s fertility, but its effect is different depending on the age of each patient, for example, if the patient is a young woman, then the effect of chemotherapy drugs on her may be transient, and most patients have Most patients may regain the ability to have children after chemotherapy. Therefore, we must pay attention to ovarian protection during chemotherapy. At present, the main ovarian protection agents are drugs such as goserelin, which are given 1-2 months or at least 2 weeks before chemotherapy, and once a month during chemotherapy. Regular application may be expected to protect the function of the ovaries. The chances of recovery of ovarian function after chemotherapy are relatively higher than in patients who do not use ovarian function inhibitors.
