Cancer can have an impact on your sexuality and may alter your priorities. Surgery, pain or the unwanted effects of the medication are all physical factors that may upset your intimate relations. In the same way, anxiety, certain treatments or changes to your body image may reduce your libido. The chemotherapy does not in itself reduce your sexual capacity or desire.
During chemotherapy the residue of the medicine is to be found in minute quantities in sperm or vaginal secretions up to 72 hours after administration, so it is important to use a condom during that time to protect your partner from direct contact with those substances.
Specialists in sexual health and cancer are available at the HUG and the cancer care teams are aware of the subject.
The association Prosca offers support for men with prostate cancer.
Once an anti-cancer treatment has been decided on for the man or the woman, it is inadvisable for the couple to plan a pregnancy. Treatment can have side effects on the foetus.
Certain forms of chemotherapy or radiotherapy reduce the number of spermatozoa and bring about a temporary decline in fertility or even male sterility. Your doctor will inform you of the possibilities of freezing a sperm sample before your treatment begins
Some chemotherapy or radiotherapy can temporarily or permanently reduce ovarian function. If you want to have a child or think you may want to later, it is important to discuss with your doctor the probable effects of your cancer and of its treatment on your fertility.
In some cases taking measures to preserve fertility (freezing the ova, in-vitro fertilization) can be envisaged before treatment is begun with a view to a subsequent pregnancy.
Chemotherapy can trigger early menopause with the appearance of the following customary symptoms: hot flashes, an irregular or non-existent menstrual cycle, dryness and changes to the vagina.
Do not hesitate to speak to your doctor about the choice of an appropriate treatment.
During treatment you are recommended to use appropriate contraception as prescribed by your doctor. Even if the menstrual cycle is interrupted or the production of sperm diminished, there is still a risk of a child being conceived.
