Fertility preservation (egg/sperm freezing)

Fertility preservation involves freezing eggs (oocyte cryopreservation), sperm, or embryos for future use. It is pursued by individuals who want to delay parenthood, those facing medical treatments that may affect fertility (cancer treatment, surgery), transgender individuals before hormone therapy, and people who want to preserve their reproductive options.

1. Egg Freezing

  • Consult a reproductive endocrinologist (RE) — Schedule an initial consultation to discuss your goals, medical history, and timeline. The RE will assess your ovarian reserve through blood tests (AMH...
  • Choose a fertility clinic — Compare clinics based on success rates (SART.org publishes data), location, cost, and patient reviews.
  • Complete pre-cycle testing — Blood work (infectious disease screening, hormone levels), ultrasound, and sometimes genetic screening.
  • Begin ovarian stimulation (Days 1-14) — Starting on day 2-3 of your menstrual cycle:
  • Daily self-administered hormone injections (gonadotropins) for 10-14 days to stimulate multiple egg production
  • Monitoring visits every 2-3 days (blood work + ultrasound) to track follicle growth
  • Additional medications to prevent premature ovulation
  • Trigger shot (Day ~12-14) — When follicles are mature, a trigger injection (hCG or Lupron) is given to finalize egg maturation.
  • Egg retrieval (36 hours after trigger) — A 15-30 minute outpatient procedure under sedation. A needle guided by ultrasound retrieves eggs from the ovaries. Recovery takes 1-2 days. Most women retri...
  • Vitrification (flash-freezing) — Mature eggs are frozen using vitrification, which prevents ice crystal formation and improves survival rates compared to older slow-freezing methods.

2. Sperm Freezing

  • Consult with a fertility specialist or urologist — Discuss your reasons, timeline, and any health concerns.
  • Provide a semen sample — Collected via ejaculation at the clinic or at home (delivered within 1 hour). The sample is analyzed for count, motility, and morphology.
  • Freezing and storage — The sample is processed, divided into vials, and frozen. Multiple samples may be collected over 2-4 weeks for a larger bank.
  • Ongoing storage — Samples stored in liquid nitrogen. Annual storage fees apply.

3. Egg Freezing

  • Cost $10,000-$20,000 per cycle (including medications and procedure), plus $500-$1,000/year for storage. Most women undergo 2 cycles, bringing total cost to $20,000-$40,000.
  • Success rates Depend heavily on age at freezing:
  • Under 35: ~51% live birth rate per transfer cycle
  • Over 40: ~15-20%
  • Freezing 20+ eggs (under 38) gives approximately 70% chance of at least one live birth
  • Best age to freeze Before 35. Egg quality declines significantly after 35, with a sharp drop after 38.
  • Time commitment One cycle takes about 2 weeks of active treatment, plus 1-2 weeks of planning and testing.
  • Side effects Bloating, mood swings, injection site soreness, and in rare cases, ovarian hyperstimulation syndrome (OHSS).

4. Sperm Freezing

  • Cost $1,000-$4,000 total (including analysis and initial storage), plus $200-$600/year for storage.
  • Success rates Sperm freezes and thaws very well. Post-thaw survival rates are typically 50-75%, which is usually more than sufficient for IUI or IVF.
  • Time commitment 1-3 visits over 2-4 weeks.
  • Simplicity The process is significantly simpler, faster, and cheaper than egg freezing.

5. Insurance Coverage

  • 22 U.S. states (plus D.C.) have enacted laws requiring some level of fertility treatment insurance coverage as of 2025, though coverage scope varies widely.
  • Employer benefits Many large companies (Apple, Google, Meta, Amazon, etc.) offer fertility preservation benefits covering egg freezing.
  • Medical necessity Insurance is more likely to cover fertility preservation before cancer treatment or other medical procedures that may affect fertility.
  • Elective freezing Less commonly covered by insurance. Check your plan's specific benefits.

Common Mistakes

  • Waiting too long
  • Assuming one cycle is enough
  • Not researching clinic success rates
  • Underestimating the cost
  • Not checking insurance before starting
