Chemotherapy drugs may lower the number of sperm cells, reduce their ability to move, or cause other abnormalities. These changes can result in infertility, which may be temporary or permanent. It is important that you discuss this issue with your doctor before you begin chemotherapy. Men undergoing chemotherapy should use an effective means of birth control with their partners during treatment.
Anticancer drugs can damage ovaries and reduce the amount of hormones they produce.
A result, some women find that their menstrual periods become irregular or stop completely while they are having chemotherapy. Because of the damage to the ovaries, infertility may result or the ability to become pregnant may be lost. It is advisable during chemotherapy to avoid pregnancy and to use effective birth control measures. Anticancer drugs may also cause birth defects. Sexual feelings and attitudes vary among people during chemotherapy.
