When is fertility preservation recommended for fertility problems after cancer treatment?

Cancer treatment can affect egg supply, sperm production, hormone signals, or the ability to carry a pregnancy. Fertility after treatment varies with the cancer, treatment exposure, age, and recovery. Tests may include hormone assessment, ovarian reserve testing, semen analysis, or imaging. A result showing reduced fertility does not by itself decide whether preservation or assisted reproduction is suitable.

Request a fertility referral if treatment has ended and you are considering biological parenthood. Bring treatment dates and medicine names, and mention any menstrual changes, erectile or ejaculation concerns, or previous stored eggs, embryos, or sperm. The specialist can discuss freezing reproductive material, using material stored before treatment, donor options, or other routes to parenthood. Decisions should reflect recovery and any advice about pregnancy timing.

Arrange assessment if periods have not returned, there is persistent pelvic or testicular pain, sexual function changes, or concern about pregnancy after treatment. Seek urgent care for sudden severe pain, heavy bleeding, fever, or acute breathlessness.

Ask which tests are useful now, whether fertility may recover, what preservation choices remain, how cancer follow-up affects pregnancy planning, and which specialist will manage the next step.
