Fertility Preservation Before Blood Cancer Immunotherapy — The Window Closes at Cycle One

Yes, and before the first cycle of anything. Fertility preservation is time-limited in a way that almost nothing else in cancer care is. Sperm freezing often takes one to three days. Egg or embryo freezing takes about two weeks. Once chemotherapy has started, what can be stored is poorer, and some options close completely.

Start with what is actually planned for you. Most people treated for lymphoma, leukaemia or myeloma in India never receive immunotherapy at all. First-line multi-drug chemotherapy, sometimes with radiotherapy, does the work in the large majority of people treated for the first time, and immunotherapy has a defined later role, mainly in disease that comes back or does not respond. Being told you are not a candidate usually means the standard pathway is working as intended.

That matters here because the fertility risk follows the chemotherapy, not the immunotherapy. The drug families used in blood cancer differ widely in how much they affect eggs and sperm, and the highest risk of all sits with the conditioning treatment given before a stem-cell transplant and with total-body radiotherapy. Which regimen is planned, at what dose, and whether a transplant is on the horizon are the questions that decide how urgent this conversation is.

The gap this page exists to close is a practical one. Guidance from ASCO, ESMO and NCCN is consistent that fertility should be discussed with every patient of reproductive age as early as possible, and referral offered to those who want it. In practice it is one of the most frequently skipped conversations in the rush between diagnosis and the first cycle, because everyone in the room is focused on starting treatment.

Fertility preservation is carried out at assisted-reproduction and andrology units, not at a cancer centre. CION’s part is to raise it before treatment starts, say honestly how much time the disease allows, and coordinate the referral so that finding a unit does not fall to your family in the same week as the diagnosis.

Nothing here decides what is possible for you. That comes from your age, the diagnosis, the regimen planned, how urgently it must start and your own fertility baseline, read together by the haemato-oncology and fertility teams.

Freezing sperm, eggs, embryos or ovarian tissue, depending on who you are and how much time the disease allows. Everything else is either an addition to those or a way of protecting the ovaries from radiation. The right option is decided by age, whether puberty has been reached, whether there is a partner, and above all by the treatment start date.

Read the table as a menu of what exists, not a list of what is available to you this week. Availability varies by city and by unit, and the pre-pubertal options in particular are concentrated in a handful of centres.

Which of these applies is a joint decision between the haemato-oncology team and a fertility specialist, made against current ASCO, ESMO and NCCN guidance on fertility preservation in people of reproductive age.

The referral should be made the same week the treatment plan is agreed, and ideally the same day. Sperm freezing usually needs one to three days. Egg or embryo freezing needs about two weeks. Ovarian tissue freezing is normally one operation. The disease decides which of those the calendar can hold.

Work backwards from the start date rather than forwards from the diagnosis. If treatment is due to begin in three weeks, almost everything on the list is open. If it begins on Monday, the realistic conversation is about sperm freezing, ovarian tissue freezing, or proceeding without preservation and documenting why.

The step that most often costs time is not the procedure. It is finding the unit, getting the appointment and completing the consent and screening paperwork. That is administrative time, and it can be started the moment a plan exists, in parallel with staging scans and pre-treatment tests rather than after them.

Ask the question even when it feels premature. Being told there is no time is a clinical answer that can be acted on. Not being told anything leaves a decision made by default, and it is the one part of the treatment plan that cannot be revisited later.

If treatment has already started, the conversation is different but not over. Ask about assessing fertility after treatment finishes, and about what is worth preserving between lines of treatment or before a transplant referral.

For most people with lymphoma or myeloma, it does not. Sperm freezing rarely moves the start date. Around two weeks for egg or embryo collection is often workable when the disease is not an immediate threat. Acute leukaemia is the usual exception, because treatment may have to begin within hours to days.

The judgement belongs to the treating haemato-oncologist, who is weighing the risk of waiting against the value of what could be stored. Ask for that judgement explicitly, because “there is no time” sometimes means the disease genuinely cannot wait, and sometimes means the referral was never made.

No page can tell you whether your own treatment can wait a fortnight. What it can tell you is that the question is legitimate, that it should be asked on the day the plan is made, and that the answer should be recorded in your notes either way.

CION does not perform stem-cell transplants and does not provide CAR-T or any other cell therapy. Both are carried out at designated transplant and cell-therapy centres. What CION provides is medical oncology assessment, day-care immunotherapy where it is indicated, and coordination of the referral so that arranging it does not fall to your family.

These routes matter to a fertility page more than any other part of the pathway. The conditioning treatment given before a stem-cell transplant, and total-body radiotherapy where it forms part of the plan, carry the highest risk to future fertility of anything used in blood cancer. If a transplant is even being considered, preservation is more urgent, not less.

The practical failure is one of sequencing. Families often raise fertility at the transplant centre, at the point of admission, when the decision has already been taken and the schedule is fixed. Raise it while the referral is being organised, at the centre making the referral, when there is still a calendar to work with.

Cell therapy is usually preceded by chemotherapy of its own, and the designated centre delivering it runs a formal multi-year follow-up programme afterwards. Fertility questions belong inside that programme too. Ask which centre, who holds the long-term follow-up, and whether anything can be stored before the referral moves.

Ask these three questions early: is a transplant a realistic part of my plan, does the plan include radiotherapy to the pelvis or the whole body, and can anything be stored before the referral goes out.

• Does the planned regimen carry a high, moderate or low risk to fertility? Your team can answer this from the protocol. It is the single fact that decides how hard to push on everything below.
• How many days do I actually have before treatment must start? Ask for a number, not an impression. The number decides which options are open.
• Can the fertility referral be made today? The paperwork and the appointment take longer than the procedure does, and both can run in parallel with staging.
• Is a stem-cell transplant a realistic part of my plan? If it might be, preservation becomes more urgent, because conditioning treatment carries the highest fertility risk in the pathway.
• What contraception is advised during treatment, and for how long afterwards? This applies whether or not anything is preserved, and it is easy to leave unsaid.
• Please record the discussion in my notes. Whatever is decided, including a decision not to preserve, it should be written down with the date and who was present.

Cost belongs in the same conversation, and it is rarely covered where cancer treatment is. Fertility preservation is generally billed separately by the assisted-reproduction unit, with an annual storage charge for as long as material is kept. Any figure quoted anywhere, including by us, is indicative only, as of August 2026. Ask for a written estimate covering the procedure, the first year of storage and the renewal after that. On the cancer side, what actually drives the bill is set out in Cost of Blood Cancer Immunotherapy in India.

• If a transplant may follow first-line treatment, preservation matters more — Immunotherapy for Multiple Myeloma shows how a pathway with a transplant in it is sequenced.
