Most of the ways of preserving fertility have to happen before the first dose of chemotherapy, and two of them take about a fortnight. Lymphoma is often treated quickly, so this is one of the few decisions in the illness with a real deadline, and it is easy to miss while everything else is being arranged.
**Why the clock matters here more than in most cancers.** Lymphoma is commonly diagnosed in people of reproductive age, and an aggressive lymphoma is usually treated within days or a very few weeks of diagnosis. Lymphoma Action says fertility preservation is generally more effective when it begins before lymphoma treatment, and that sperm must be banked before treatment starts because treatment affects both the number and the quality of sperm.
**What takes how long.** Sperm banking takes a visit or a few visits and can usually be arranged quickly; Lymphoma Action says NICE recommends that all men whose cancer treatment could affect their fertility be offered it, and that it is also an option for teenagers who have been through puberty. Egg freezing is the slower one: Lymphoma Action describes about two weeks of daily injections to stimulate the ovaries before the eggs are collected under ultrasound guidance. Embryo storage begins the same way and takes the same time, with the added point that if a partner withdraws consent later the embryos must be destroyed. Ovarian tissue freezing is keyhole surgery and is possible before puberty. Testicular tissue freezing is offered for research only, in a very small number of centres, and no baby has yet been born through it.
**What NICE says, as Lymphoma Action quotes it.** There should be no lower age limit on who is offered fertility preservation before treatment; people who go on to have fertility difficulties should be offered support and counselling; preservation may be available up to the age of 40, although this varies across the NHS; and the impact of the cancer and its treatment on future fertility should be discussed at diagnosis between the person and their cancer team.
**What the risk actually is.** It depends on the drugs, the total dose and, for women, age. Lymphoma Action says most women who have lymphoma treatment can have children naturally afterwards, that periods very commonly stop during chemotherapy and usually return in younger women, and that chemotherapy does not affect the uterus's ability to carry a pregnancy. High-dose chemotherapy before a stem cell transplant raises the risk; radiotherapy to the pelvis can cause temporary or permanent infertility in both sexes; and total body irradiation usually causes permanent infertility and often leaves a woman unable to carry a pregnancy. In the German HD13 to HD15 survivor analysis, after six to eight cycles of escalated BEACOPP menstrual activity was reported by 82 per cent of women under 30 and 45 per cent of women aged 30 or more.
**The question to ask on the first day.** Whether the planned treatment carries a fertility risk, whether a referral to a fertility clinic has been made, and how many days there are before treatment must start. Those three answers together are the decision. If treatment cannot safely wait two weeks, the options narrow, and knowing that early is better than finding it out afterwards.
