During ejaculation, semen containing millions of sperm cells is released from the male reproductive system. On average, a single ejaculation can release up to 500 million sperm. If these sperm reach the fallopian tubes, fertilization and embryo formation can occur.
Since sperm cannot survive for long periods inside the body, sperm freezing in cancer patients is a reliable method to preserve fertility. In this process, healthy sperm are stored at –196°C in a sperm bank and can be thawed later when the patient is ready to conceive.
One of the most important indications for sperm freezing in cancer patients is before undergoing cancer treatment. Chemotherapy, radiation, and surgeries can severely damage sperm quality and quantity. Freezing sperm beforehand allows men to retain their chance of fatherhood even after aggressive cancer treatments. Testicular cancer and prostate cancer are two common examples where sperm freezing in cancer patients is especially recommended before surgery or other treatments that may impair fertility.
Just as women experience reduced egg quality with age, men also face declining sperm quality. Aging can lead to reduced motility, abnormal morphology, and increased DNA fragmentation. For older men, sperm freezing in cancer patients and other high-risk individuals is a proactive way to preserve fertility. This procedure is available at Dr. Pegah Keramati’s advanced fertility center in Shiraz.
Certain jobs expose men to heat, radiation, or harmful chemicals that negatively affect sperm production. Men working in mines, chemical laboratories, bakeries, the military, or aboard ships may be at risk. In such cases, sperm freezing in cancer patients and men with hazardous occupations is strongly advised to safeguard their future reproductive potential.
Some surgeries and medications—especially those affecting the nervous system or reproductive organs—can impair sperm production or ejaculation. For these patients, consulting a specialist about sperm freezing in cancer patients is crucial before starting treatment.
