Fertility preservation before chemotherapy: the options

The main options are sperm banking for men and teenage boys who have gone through puberty, egg freezing for women and teenage girls, and embryo freezing for couples. Other options, used in selected situations or specialised centres, include freezing ovarian tissue, freezing testicular tissue for boys who have not yet gone through puberty, shielding or moving the ovaries away from radiotherapy fields, and medicines that quieten the ovaries during chemotherapy. Each option differs in how it works, how long it takes, how much it costs, how established it is, and who it suits. The right choice depends on sex, age, whether puberty has happened, relationship status, the time available before treatment must start, the type of cancer and your personal and family values.

Sperm banking is usually the quickest and simplest option: semen samples can be provided and frozen within days, often before the first cycle without delaying treatment. Egg and embryo freezing involve around two weeks of hormone injections to stimulate the ovaries, monitoring scans and a short procedure to collect eggs, so they need a little more time and are considerably more expensive. For some hormone-sensitive cancers, special stimulation approaches can be used. Ovarian tissue freezing involves a small operation to remove and freeze ovarian tissue, which can be done quickly and does not need hormone stimulation, but it is available only in some centres and later use is more complex. Ovarian suppression medicines are sometimes used during chemotherapy to try to protect ovarian function, but they are not a reliable way to preserve fertility on their own. Because time is short, the most useful step is an urgent referral to a fertility specialist who works with cancer patients.

Preservation offers a chance, not a certainty

Stored sperm, eggs or embryos improve the chance of biological children later, but success depends on many factors.

Legal and consent rules apply

Assisted reproduction in India is regulated, with rules on consent, storage and use. Clinics will explain them.

Storage costs continue

Frozen sperm, eggs and embryos need storage fees each year.

It cannot tell you which option is right for you or whether there is time before your treatment. Those decisions depend on your cancer, how urgently treatment must begin, your age and circumstances, and are made by your oncologist and fertility specialist with you.

It also cannot give success rates. The chance of a future pregnancy depends on age at preservation, the number and quality of sperm, eggs or embryos stored, and later fertility treatment. Ask the fertility specialist for information relevant to you.

Hormone-sensitive cancers

For some breast cancers, fertility clinics use special stimulation methods. Your teams will discuss safety.

Unmarried women

Egg freezing allows preservation without a partner and avoids embryo consent issues.

Religious and ethical views

Some families have views on embryo storage. Egg freezing or other options may suit them better.

If preservation is not possible

Donor options, adoption and later fertility testing remain possible paths.

Children and teenagers

Options for young people are more limited. Specialist paediatric teams can advise.

Cost and insurance

Preservation is rarely insured. Ask for written estimates, including storage fees.

Documentation

Keep consent forms and storage details safe, and update the clinic if your contact details change.

Emotional support

Making fertility decisions quickly during a cancer diagnosis is stressful. Counselling can help.

Choosing between egg and embryo freezing

For women with a partner, the choice between freezing eggs and freezing embryos involves practical and personal considerations. Embryos are created by fertilising eggs with a partner's sperm before freezing, and have long been used successfully in fertility treatment. Egg freezing keeps options open if the relationship changes, avoids some ethical and consent issues, and suits women without a partner. Some couples freeze a mix of both. Consent rules mean that embryos usually need agreement from both partners for future use, which can become complicated if a relationship ends. Fertility specialists and counsellors can help couples think through these questions quickly.

Protecting fertility before puberty

Before puberty, sperm and mature eggs cannot be collected, so the options are different. For girls, ovarian tissue freezing may be offered in specialised centres, with tissue removed through keyhole surgery and stored for possible future use. For boys, testicular tissue freezing is still considered experimental and is available only in research settings. Parents should ask the paediatric oncology team early whether any option applies, and what realistic expectations are.

Counselling alongside preservation

Fertility counselling helps people understand choices, cope with uncertainty and make decisions that fit their values. It can be offered to patients, partners and parents together, and is especially valuable when time is short and emotions are running high.

What to do next

Ask your oncologist about fertility risk and time available, request an urgent referral, discuss the options, timelines and costs with a fertility specialist, involve your family where appropriate, and decide before the first cycle whenever possible.
