Causes / Why People Need It ?

  • Cancer treatments (chemotherapy, pelvic radiation) that harm eggs or sperm.
  • Major surgery that removes or damages reproductive organs
  • Medical conditions (e.g., severe endometriosis, autoimmune disease, sickle cell disease needing transplant).
  • Planned gender-affirming hormone/surgical care.
  • Occupational or environmental exposures (radiation, toxins).
  • Elective reasons, delaying childbearing for personal/career reasons (age-related decline).

When It’s Considered ?

  • At diagnosis of cancers or before other gonadotoxic therapy, immediate referral to fertility specialists is recommended so preservation can be planned without unnecessary treatment delay.
  • If a planned surgery may remove or injure reproductive tissue.
  • When a person wants to delay pregnancy and wishes “insurance” against age-related decline.
  • For children/adolescents facing therapy that risks future fertility (tissue freezing options).
  • For transgender patients before starting hormones or surgery.

Benefits

  • Keeps the option of biological children open
  • Reduces anxiety for patients facing fertility-threatening treatments.
  • Many methods have good success when performed appropriately and early.

Types

  • Egg (oocyte) freezing
  • Embryo freezing (IVF + freeze embryos)
  • Sperm freezing (semen cryopreservation; surgical retrieval if needed)
  • Ovarian tissue cryopreservation (and later reimplantation)
  • Gonadal shielding / ovarian transposition and medical suppression (GnRH agonists) as adjunct strategies
  • Counseling and oncofertility coordination

General Procedure

  • Rapid multidisciplinary counseling (oncology + fertility).
  • Baseline tests (hormones, ovarian reserve, infectious disease screen).
  • Choose the method best for age, time available, partner/donor status.
  • Collect gametes/tissue (stimulation/retrieval or surgical biopsy or semen collection).
  • Cryopreserve (vitrification or controlled freezing) and long-term storage in liquid nitrogen.
  • Later thaw/use with ART (IUI/IVF/ICSI) or reimplant tissue.

Results

  • Outcomes depend strongly on age (especially for eggs), number/quality of preserved gametes, the treatment that caused damage, and the method used later (IUI, IVF, ICSI).
  • Some methods (sperm, embryos) have long, proven track records; others (ovarian tissue) are newer but increasingly successful.
  • Not every preserved sample will produce a pregnancy; counseling about probabilities is essential.
